The International Energy Agency (IEA) estimates that globally US$38 trillion must be invested in energy supply infrastructure from 2011 to 2035—with US$17 trillion going just to the power sector. On top of that, enormous sums will be needed in the power sector to handle additional investment needs stemming from the green growth agenda and related policies. Already, in 2008, for the first time, renewable energy (including large hydro) attracted more power sector investment globally than fossil-fuel based technologies (UNEP 2011). By 2035, renewable sources of energy are expected to triple (IEA 2010). This growth in renewables is being driven by an alignment of global factors: First, demand for energy from emerging economies has risen sharply. China alone increased its oil consumption by 840,000 barrels a day between 2005 and 2007. Over the next 25 years, 90 percent of the projected growth in global energy demand will come from developing countries, with China, India, Indonesia, and Brazil leading the pack. Second, competition for energy resources has increased. The higher demand for energy and faster use of natural resources is creating greater competition for limited resources—which sometimes plays out in volatile demand and related price fluctuations. Third, oil and gas prices have been rising. Whereas historical oil price shocks were primarily caused by physical disruptions of supply, the price run-up of 2007/08 was caused by strong demand confronting stagnating world produc- tion. More recently, the uprisings in the Middle East in part helped push the world oil crude price above US$120 in April 2011, although this was still below the July 2008 record of US$145 a barrel. In real terms, these prices are compa- rable to those that caused the 1973 and 1979 energy crises. But if the oil price xi   xii Overview Chapter rises high enough, the use of alternative clean fuels could help control carbon emissions from fossil fuel use. Fourth, political concerns about fossil fuel energy security have re-emerged in many countries. Take the case of the European Union (EU). The Ukrainian gas supply crises of 2006 and 2009 resulted in the EU receiving lower supplies of Russian gas, owing to a dispute between Ukraine and the Russian Federation. This development has heightened concerns about gas security in the EU and reduced politicians’ willingness to allow the power sector to become more dependent on combined cycle gas turbine power plants (Noel 2009). Fifth, the Kyoto Protocol’s implementation in early 2005, along with greater political interest in climate change has refocused the energy debate. The green growth agenda is now a topic of discussion at the highest political levels, with politicians debating measures to control emissions and switch to a low-carbon growth path. With such enormous sums needed, public-private partnerships (PPPs) could play a big role. But the financial crisis has raised worries about funding, and much is still not known about how best to attract PPPs. This report reviews the evidence to date with sectoral reforms and considers different approaches in varying cir- cumstances to help outline the potential role of the private and public sector in (1) strengthening the corporate governance of private and public utilities; (2) helping governments to establish legal, regulatory, contractual, and fiscal frameworks; and (3) improved market governance to attract private investment. Chapter 1 reviews the impact of the recent financial crisis on PPP invest- ment compared with what happened in earlier financial crises. It also looks out the latest projections for additional power sector investment needed because of climate change and the possible sources of financing. Chapter 2 examines how PPP investment in the power sector has fared. It also gives the results of an econometric study that explores which types of incentives and variables matter most to PPPs when they are weighing entering the power sector, espe- cially in renewables, and what influences the ongoing level of investment. The idea is to provide a powerful benchmarking tool at the sector and country levels against which governments and policy makers can evaluate progress on this issue. Chapter 3 examines four case studies—in China, Brazil, Peru, and Mexico—to identify, disseminate, and promote best practices on alternative ways to attract PPPs. The key messages are: • While many private electricity projects have been delayed and financing costs have increased, the impact of the global financial crisis was less severe than that of previous crises that originated in developing countries • This resilience stems from developing countries’ need to expand generation capacity, electricity sector reforms and better regulatory frameworks, packages to attract independent power producers, and short-term solutions (such as rental power plants) Overview Chapter xiii • Although the crisis brought both short-term relief—lower electricity demand to take the pressure off supply shortages—it also brought longer term problems—higher financing costs for infrastructure • The sharply reduced appetite of commercial banks for long-term financing in many countries makes international financing institutions especially valuable for private projects • When weighing whether to enter the power sector, PPPs weigh sectoral gov- ernance (feed-in tariffs and electricity regulation), economy-wide governance (control of corruption and degree of democracy), short-run economic drivers (population and income), and long-run climate change (PPP investment in transmission and renewables, the oil price, and legal commitments, such as the Kyoto Protocol, and green policies). Why Attracting PPPs Matters What exactly are PPPs and why do they matter so much in the power sector? Ever since a first wave of reform in the 1970s and 1980s, policy makers, donors, and international financial institutions (IFIs) have attempted to improve per- formance while maintaining public ownership. But these attempts to reform state-owned enterprises (SOEs) largely failed, except for a few difficult-to- sustain exceptions. For instance, performance-based contracts were introduced, as were a number of managerial and policy reforms aimed at increasing the autonomy and accountability of managers, reforming the nature and functions of SOE boards of directors, introducing and reinforcing financial and manage- rial information systems, and pursuing a range of other mechanisms short of ownership change. Typically, SOE reforms were not implemented or failed to produce the desired results. Even when successes were recorded, they could not be sustained over time. For that reason, in the 1990s, there was a big push for privatization and the use of PPPs (see box O.1)(see table O.1). By 2004, PPPs already represented the lion’s share in electricity generation and distribution, particularly in middle- income countries. However, even after 20 or more years of electricity market reforms, there is still an unfinished agenda. As noted in Pollitt’s (2009) review of progress with electricity market reforms in the European Union (EU), it is difficult to find Table O.1  PPPs Play a Major Role in Developing Country Power Sectors extent of private sector participation in developing countries as of 2004 Existence of private capital Low income Lower middle income Upper middle income Electricity generation 41% (59) 48% (42) 58% (33) Electricity distribution 29% (62) 37% (43) 48% (33) Source: Estache and Goicoechea 2005. Note: The entries refer to the shares of sample of countries with some form of private capital (percent of total sample size for each country is given in parenthesis). xiv Overview Chapter Box O.1 A Snapshot of PPPs A PPP takes the form of a contract between a private sector entity and the government that calls for the private sponsor to deliver a desired service and assume the associated risks in exchange for the right to earn an adequate return. The government may be currently provid- ing that service, or it may be a new service that would benefit the country and economy. Risk allocation is at the heart of how PPPs are structured. In other words, the public sector passes on a portion of the risk of service delivery to the private sector. The nature of the partnership between the private and the public sector can range from fairly simple contractual arrangements to supply a specific service, to complex arrange- ments to design, construct, operate, maintain, finance, and provide services. The figure below illustrates the broad spectrum of private sector participation in service delivery. As more equity and control is transferred to the private sector, so too are the risks, commercial and noncommercial. PPPs, in which the private sector can provide significant amounts of financing for the project, may provide relief to government budgets, as well as significant transfers of skills and know-how. With these savings, the government could invest in projects that are less amenable to PPPs. The majority of new investment in electricity generation has been through build-operate- transfer contracts, sometimes combined with leases for existing plants. The absence of liberal- ized wholesale power markets means that investors rely on long-term agreements with (usually) state-controlled or guaranteed purchasers. Under these conditions, it is natural to link the purchase agreement to the license to operate the power plant. From a regulatory point of view, however, the downside of long-term power purchase agreements is that they can impede subsequent liberalization and the introduction of competition. Management and outsourcing contracts are operating contracts without any investment obligations. In the early phase of privatization, most countries were focused on divesting assets, but in recent years, these contracts have become more common as countries have found it harder to attract private operators if the government is hesitant to impose cost- reflective tariffs or cede control of the basic network infrastructure.

A more recent review revisiting policy options for unbundling for developing countries (Vagliasindi and Besant Jones, 2012) shows a current distribution of power markets around intermediate structures between full integration and full unbundling that suggests there has not been a linear path to reform in practice. Instead, many developing countries may retain intermediate structures for foreseeable future. For now, PPPs, and in some cases public ownership, remain a significant way in which governments can attempt to insure against and potentially prevent undesirable outcomes of embracing the classic paradigm of private sector participation as a fit to all strategy. How PPPs Weathered the Financial Crisis While many private electricity projects have been delayed and financing costs have increased, the impact of the global financial crisis—with 15 large projects implemented in 2009—was less severe than that of previous crises that origi- nated in developing countries. Investment commitments to PPP electricity projects in developing countries reached US$46.5 billion in 2007, about double that of the previous year, and remained around the same level in 2008. Such a level represents an increase of over 150 percent from the level in 2004, and brings investment just 17 percent below the peak level reached in 1997. However, this recovery was highly selective. Three countries—Brazil, India, and the Russia—accounted for most of the growth in 2007–09 (figure O.1). This resilience stems from developing countries’ need to expand generation capacity, electricity sector reforms and better regulatory frameworks, packages to attract independent power producers, and short-term solutions (such as rental power plants). The crisis brought short-term relief—lower electricity demand to take the pressure off supply shortages. However, it also brought longer-term problems in the form of higher financing costs for infrastructure. Compounding matters is that the new green growth agenda imposes significant new investment requirements on the power sector. Private sector investment is critically needed, but it is unlikely to provide the daunting scale of financing required in the coming decades. Continuous technological improvements (com- bined with reasonably benign fossil fuel prices) ensured significant real unit cost reductions in power costs (and even larger reductions in the costs of energy ser- vices) between 1900 and 2000. However, since then, climate policy (with the objective of reducing carbon dioxide and equivalent greenhouse gases (GHG)) and sister policies aimed at promoting the percentage of electricity generated by renewables (and to reduce demand in high demand countries) have begun to significantly drive costs in many power sectors. While this has mainly affected Organisation for Economic Co-operation and Development (OECD) countries (particularly within Europe), it has implica- tions for developing countries many of whom have adopted renewable policies. China now is the largest investor in renewable energy, with the United States xvi Overview Chapter Figure O.1  The Recovery Has Mainly Benefited Three Countries investment commitments to electricity PPP projects in developing countries 2009 US$, billiona 80 70 Global financial crisis 60 Asian crisis US$ in billions, 2009 50 40 Russian crisis 30 Argentine and Brazilian crisis 20 10 0 95 00 05 09 10 19 20 20 20 20 Year Q1 Brazil China India Russian Federation Indonesia Philippines Remaining countries Thailand Sources: World Bank and PPIAF, PPI Project Database.

The industrial countries’ greater focus on greening growth has indirectly created learning benefits for other countries in renewables and funding for projects via the Clean Development Mechanism of the UN Framework Convention on Climate Change (UNFCCC)—which allows for creating trad- able carbon credits from investments in renewable projects in the developing world. But the downside may be a slowing of technical progress and investment in conventional generation technologies. The policy targets at the individual country level are ambitious and create significant investment requirements for the power sector. Such investments in low carbon generation (such as nuclear) and renewables exposes investors to substantial government policy change risks, especially given that the payback periods for many of these investments are long (15–30 years). PPPs and public ownership may be a way to ensure that the large scale investment requirements Overview Chapter xvii Figure O.2  China Leading the Way in Investing in Renewable Energy new financial investment in renewable energy, 2011, US$ billion 60 50 40 US$, billions 30 20 10 0 a il ly A in az US Ita Ch Br Countries Source: Bloomberg New Energy Finance. of the power sector are met. Moreover, post-financial crisis, the sharply reduced appetite of commercial banks for long-term financing in many countries makes international financing institutions especially valuable for private projects. One result of the changed market environment is the increased uncertainty on whether investment will be able to catch up with future demand for power and climate change targets. According to the results of a global survey carried out in 2009 by Price Waterhouse Coopers (2009), two-thirds of about 70 senior power utility executives report that a shortage of capital is having a major impact on their activities. Senior executives in our survey are worried about the high costs also driven by greater uncertainty associated with projects. Two-thirds also refer to problems in securing finance as a medium or high barrier to project development. Surveyed power utilities emphasize the importance of greater clarity of climate change policy but express concern that the economic recession is undermining the chances of an effective response to climate change. Nearly 60 percent feel that their renewable energy investment programs are being affected by the lack of clarity from governments on renewable energy targets and finan- cial support for renewable energy. The importance of greater certainty on both targets and economic mechanisms to support renewable energy is highlighted by the fact that only 28 percent of respondents believe that unsubsidized renewable power can compete commercially against fossil fuel generation. xviii Overview Chapter Asked if the economic recession would slow down responses to climate change, 79 percent felt it would, with two thirds of the 79 percent saying it would have a high or very high slowdown impact. Best Ways to Attract PPPs Which types of energy are PPPs investing in? Of the total PPP investment in electricity generation, fossil fuels account for the lion’s share—about 75 per- cent (figure O.3). Coal accounts for 35 percent, natural gas 24 percent, and fuel oil 15 percent. Total investment in renewables represents a mere 4 percent, if hydropower, at 22 percent, is excluded. Within that group, wind and geothermal technologies have almost an equal share of about 40 percent, with waste limited to 20 percent. Although the current share of PPP investment in renewables among devel- oping countries is still quite small, the data show a dramatic rise in this type of investment—following the adoption of the Kyoto Protocol in 1997 and the introduction of support schemes (particularly feed-in tariffs) in Europe in the early 1990s. The East Asian and Russian crises in 1997/98, as well as the Latin American crisis in 2001, hurt PPP investments in renewables, but recent short- run shocks have taken less of a toll. Among the fossil fuels, there is some evidence of switching of PPP invest- ment from oil and coal to natural gas. Indeed, natural gas is the only fossil fuel that has substantially increased its share of PPP investment from about 10 per- cent in the early 1990s to above 50 percent in 2002, then decreasing to below 40 percent in 2008—although in dollar terms, 2008 was a peak, with investment reaching above US$12 billion. There is also some evidence of switching of PPP investment from fossil fuels to hydro and renewables. Figure O.3  PPP Investment in Renewables is Still Small and Mostly in Wind and Geothermal a.

Overview Chapter xix Given this strong need to attract PPP investment in the power sector, our study examined which types of incentives matter most, not just for entry but for the level of investment. We found that for entry all of the variables—sectoral and economy-wide governance, short-term economic drivers, and long-run climate change—are critical but the governance variables are less critical than the other ones for the level of investment (see tables O.2 and O.3). The highlights are: • Control for corruption and degree of political competition primarily affect investors’ decisions to enter the various power sector markets, not the subse- quent level of investment—indicating that investors seem to be adequately protected against risks • Support mechanisms, like feed-in tariffs, are crucial for attracting investors in renewable generation, but they do not succeed in displacing fossil fuel invest- ment and they could play a bigger role in affecting the level of investment in renewables. • The implementation of the Kyoto Protocol combined with higher fuel prices is important in attracting PPPs in renewables, underscoring the value of legal commitments. • Market size (as measured by population) matters more than the “afford- ability� level of consumers (as measured by income) for attracting PPPs in the power sector. Both variables play a key role in affecting the level of investments.

Best Practices in Four Developing Countries The final part of our study zeroed in on the experience of four countries in two regions—China, Brazil, Peru, and Mexico—with using various types of support mechanisms. It also examined the role that PPPs should play in efficiently expanding a transmission network system with natural monopoly characteristics and thus subject to public regulation. The countries chosen represented a wide range of schemes aimed at promoting renewable energies, different ownership (fully private or public or a mix) and market structures, and different levels of renewable energy penetration (table O.4). The case study evidence suggests that: There is a significant trade-off between effectiveness and efficiency of alter- native instruments for deploying renewables. Feed-in tariffs tended to be quite effective but to be set on the high side, reducing incentives to cut costs and posing significant strains on already stripped national budgets. Competitive auctions, on the other hand have tended to be efficient but initially low and not always the most effective instrument. Countries can scale up renewables following different paths. For Brazil, the move from feed-in tariffs to auctions enabled it to both reduce costs and deploy additional capacity. Peru followed in Brazil’s path, opting for auctions instead of introducing feed-in tariffs. On the other hand, China’s move from competitive tenders to feed-in tariffs allowed for discovery effects to determine the right level of prices to attract private investment in renewables.

Private investors require technical and regulatory certainty about the availability of renewable-ready transmission resources if they are to finance investments. The traditional reactive model of transmission regulation— developing transmission on a first-come, first-served basis—is not conducive for renewables, as it introduces extensive regulatory and technical uncertainty about whether adequate transmission will be available once the resource is generated, and transmission distances for renewables can be large. The case of China is quite telling in that the sharp increase in renewables (particularly wind) (figure O.4) posed challenges to the stability of the transmission system. In contrast, Mexico used an open season approach, with new transmission investment decided through an agreement between the Federal Electricity Commission and private investors, which facilitated better regulatory and technical certainty. xxii Overview Chapter Figure O.4  China’s Installed Wind Power Capacity Has Skyrocketed Installed wind capacity, GW 50 45 40 35 30 25 20 RE energy law 15 10 5 0 00 01 02 03 04 05 06 07 08 09 10 20 20 20 20 20 20 20 20 20 20 20 Year Newly installed capacity (GW) Cumulative installed capacity (GW) Sources: Junfeng et al. 2010; REN21 2011.

CHAPTER 1 Investment Needs and Financing Challenges The global financial crisis began with a liquidity shortfall in the U.S. banking system after the real estate bubble collapsed in 2007. By 2008, a global credit crunch had set in. Some financial institutions were bailed out by governments, investor confidence plummeted, and stock markets turned down. Both the financial crisis and the resulting economic recession hurt power sector growth and investment, which is not surprising given how vulnerable these invest- ments are because of the large amounts of capital and long maturities that are required. How are public-private partnerships (PPP) faring? This matters greatly because the need to expand generation capacity is expected to continue in the coming years as developing countries return to growth rates of 5 percent by 2010 and higher rates in subsequent years. It also matters because PPPs—in which the private sector can provide significant amounts of project financing—may provide budget relief to governments, as well as significant transfers of skills and know-how. With these savings, governments could invest in projects that are less amenable to PPPs. The push for privatization and PPPs from 1990 to the present has led to a large proportion of electricity services being delivered by PPPs in developing countries. In fact, since 2004, PPPs have represented the lion’s share in electricity generation and distribu- tion, particularly in middle-income countries. However, many countries have reported problems in recent years about delayed or cancelled projects, raising worries about whether PPPs are up to the job and whether the financing gaps are manageable. To better understand what is at stake, we undertook a study to see how the impact of this recent crisis on PPP investment and financing compares with what happened in earlier crises. This chapter reviews our findings and then examines the latest projections for additional power sector investment needed in response to climate change policies and agreements—and where the money might come from. The good news is that most developing countries weathered 1   2 A World Bank Study the storm better than might have been expected, despite some setbacks. The key messages are: • While many private electricity projects have been delayed and financing costs have increased, the impact of the global financial crisis—with 15 large projects implemented in 2009—was less severe than that of previous crises that origi- nated in developing countries • This resilience stems from developing countries’ need to expand generation capacity, electricity sector reforms and better regulatory frameworks, packages to attract independent power producers, and short-term solutions (such as rental power plants) • The crisis brought both short-term relief—lower electricity demand to take the pressure off supply shortages—and longer-term problems—higher financ- ing costs for infrastructure • The sharply reduced appetite of commercial banks for long-term financing in many countries makes international financing institutions especially valuable for private projects • The impact of climate change on the power sector’s investment needs is daunting, necessitating both public and private financing. How the Recent Financial Crisis Compares to Past Ones After the Asian financial crisis in 1997 and the economic recession in the early 2000s, private investment in the power sector remained reduced for several years with electricity supply exceeding demand in many countries (figure 1.1).

Investment Needs and Financing Challenges 3 As the economies recovered, electricity demand growth rates rebounded, justi- fying renewed investment in generation, transmission, and distribution capacity in 2006. At the onset of the 2008 global financial crisis, investment was still lagging and many developing countries were facing the prospect of electricity supply shortfalls. Thus, the period of underinvestment resulting from the previ- ous financial and economic crises served to attenuate the impact of the global financial crisis. In the last quarter of 2008, during the most severe phase of the crisis, invest- ment in electricity projects fell sharply, but it recovered strongly in 2009. After almost a decade of reduced activity, private participation in electricity has shown a strong revival in developing countries in 2007–09. Investment com- mitments (hereafter, investments) to PPP electricity projects in developing countries reached US$45.4 billion in 2007, about double that of the previous year (figure 1.2). Such a level represents an increase of over 150 percent from the level in 2004, and brings investment just 17 percent below the peak level Figure 1.2  The Recovery Has Mainly Benefited Three Countries investment commitments to electricity PPP projects in developing countries 2009 US$, billionsa 80 70 Global nancial crisis 60 Asian crisis Russian 50 crisis US$, billions 40 Argentine and Brazilian crisis 30 20 10 0 95 00 05 09 10 19 20 20 20 20 Year Q1 Brazil China India Russian Federation Indonesia Philippines Remaining countries Thailand Sources: World Bank and PPIAF, PPI Project Database.

Investment reached a level of US$53.5 in 2008 to a new peak of US$67.2 in 2009 after the recovery from the crisis. However, this recovery was highly selective. Three countries—Brazil, India, and the Russia—accounted for most of the growth in 2007–09. If these three are excluded, investment would have recovered at much lower pace in 2007/08 and have been less than half of the peak level reported in 1997. The quick recovery experienced in 2009 differs from those of previous finan- cial and economic crises. The Asian financial crisis in 1997 came after an invest- ment boom in independent power producers (IPPs) from 1992 to 1996, when the volume of private power projects financed was three times that in all previ- ous years. Private activity, measured by investment and number of projects, declined after the 1997 financial crisis in Asia and the 2001/02 economic crises in Argentina and Brazil, and remained reduced for many years in East Asia and Latin America (figure 1.3). Activity in the most active countries in the region such as Brazil, Indonesia, Philippines, and Thailand declined after the economic crisis experienced in their respective regions. Most of the recent PPP investment growth has been driven by large projects—those involving investment of US$1 billion or more—a major turn- around from earlier years (figure 1.4). After the boom of private activity in the mid–1990s, no large project was implemented in 2001/02, and two to four were implemented a year in 2003–06. This trend, however, started to be Figure 1.3  Past Crises Have Hit Originating Regions Hard investment commitments to electricity projects in developing countries by region 80 2009 US$, billionsa Global financial 70 crisis Asian crisis Russian 60 crisis 50 Argentine and 40 Brazilian crisis 30 20 10 0 95 00 05 09 Q1 10 19 20 20 Year East Asia and Paci c Europe and Central Asia Latin America and the Caribbean Middle East and North Africa South Africa Sub-Saharan Africa Sources: World Bank and PPIAF, PPI Project Database.

The appetite for large projects continued in 2008 when 15 projects of US$1 billion or more reached financial closure. Despite the reduced liquidity in credit markets and more stringent lending conditions in the aftermath of the global financial crisis, 15 large projects were also implemented in 2009. Investment in projects of US$1 billion or more increased from a range of US$3 billion to US$5 billion in 2004–06 to a range of US$21 billion to US$24 billion in 2007/08 and to a peak of US$29.3 billion in the first three quarters of 2009. Investment in projects of US$500 million to US$1 billion fluctuated between US$4.6 billion and US$6.8 billion in 2006–09. Investment in projects of less than US$500 million grew from around US$5 billion in 2004/05 to a range of US$8.6 billion to US$9.6 billion in 2006–09. Most of the projects have been new power plants in Brazil and India, and divested RAO UES power plants in Russia. Other countries that have imple- mented large projects include China (the partial divestiture of IPP), Indonesia (a new power plant), Philippines (the concession of the national transmission company), Romania (the divestiture of electricity distribution company), Thailand (a new power plant), and Turkey (a new power plant and divestiture of the electricity distribution company). Among the large projects, few were remarkably large—such as 3.3 gigawatts, US$5.7 billion Santo Antonio Hydro power plant and 3.3 gigawatts, US$4.17 billion Jirau Hydro power plant in Brazil, and 4.2 gigawatts, US$4.2 billion Mundra ultra mega power plant and 4 gigawatts, US$4.1 billion Sasan ultra mega power project in India. Of the remaining large projects, the biggest one was a 25-year US$2.9 billion conces- sion of National Transmission Corporation in Philippines. 6 A World Bank Study New private participation in electricity, however, has been affected by the financial crisis. A recent survey of electricity projects looking for finance or being awarded from January 2008 to September 2009 revealed that 42 of the 382 surveyed projects involving investments of US$16.9 billion have been delayed or are at risk of being delayed owing to the financial crisis, especially in South Asia (table 1.1). However, investment costs increased, and many projects were canceled, delayed, or forced to switch funding from private sources to interna- tional financial institutions.

Investment Needs and Financing Challenges 7 How Does the Financial Crisis Affect the Financing Gaps? Before the global financial crisis, the power sectors of most developing countries experienced continued high growth in demand for electricity. Many countries were experiencing or nearing a supply shortage, as demand outstripped the pace at which countries were building new electricity generators or replacing ageing infrastructure in generation, transmission, and distribution. The financial crisis brought both relief and new problems to the power sec- tors in developing countries facing energy crises. On the plus side, the temporary drop in demand for electricity caused by the decline in energy-intensive indus- tries delayed or relieved some of the supply shortages. For those countries that were still able to attract and maintain investment in power infrastructure, this easing of pressure on the demand side in effect prevented an impending energy crisis and created a window of opportunity for meeting sector investment needs (World Bank 2010a). In Peru, the international financial crisis halted the rapid growth of electricity demand, which actually helped avert an energy supply crisis in 2009 and reduced pressure on generation expansion. However, the cri- sis also had a negative, but not critical, impact on the financing of new invest- ments in the power sector. For some countries, however, the financial crisis contributed to an energy crisis, because although they experienced only a short-term reduction in elec- tricity demand, they also experienced a long-term reduction in investment in power sector infrastructure. Some electricity generation projects struggled to reach financial closure, while others were scrapped altogether. For example, Jamaica may experience a shortage in generation capacity by 2014, given that more than 150 megawatts of capacity was delayed compared to the precrisis investment plan, while the slow-down in demand was moderate. What happened to investment needs and financial gaps in developing coun- tries following the crisis? There is no overall estimate—and certainly it is too soon to know—but we did look at what had happened in 18 developing coun- tries, representing all regions except Sub-Saharan Africa. We tailored the “top- down� macroeconomic approach (which estimates annual investment needs for a given growth target) and the “bottom-up� engineering approach (which estimates the one-time cost of reaching specific infrastructure goals) by incor- porating revised projections for global and country specific growth. Our frame- work relied on two key transmission channels: • Macroeconomic transmission channels. The economic slowdown affected the demand for energy services, reducing investment needs in the short run. The reduction in energy demand made it easier for countries to keep up with investment in energy supply. Investment costs decreased initially owing to the drop in fuel prices, and the pace of additional investments slowed. However, the political crisis in the Middle East that began in early 2011, as well as the March 2011 earthquake in Japan, has contributed to a rise in the price of oil— from around US$38 per barrel in 2008 to a high of US$120 in 2011, before 8 A World Bank Study dropping slightly. Commodity prices have also increased since early 2010. The increase in commodity and fuel prices has pushed up investment and operat- ing costs, essentially eliminating the initial reduction in investment costs brought about by the decrease in demand for energy services. • Financing transmission channels. Deterioration in revenue collection and reduced access to finance reduced profitability and availability of funds for the energy sector. The revenue collection performance of utilities deteriorated as consumers came under increasing financial pressure. As a consequence, elec- tricity utilities in the private and the public sector were in a weaker position to implement projects. Financing became more expensive and less available in the short-term. Overall, we found that countries have been weathering shocks of the global financial crisis significantly better than in the past through real and financial transmission channels, but there are still signs of vulnerabilities (appendix A). Government Response to the Financial Crisis Many countries received emergency financial assistance in the form of multi- lateral and bilateral loans. The World Bank provided the Kyrgyz Republic with US$11 million in emergency assistance in 2008 and US$4 million in 2009 (50 percent grant/50 percent loan) to help pay operating costs at the Bishkek com- bined heat and power plant (World Bank 2010a), and the country is increasingly turning to bilateral donors, such as Russia and China, to finance large power projects (World Bank 2010a). Other countries tried to counter the effects of the financial crisis through government intervention—with mixed results (box 1.1). But in many countries, the government’s ability to respond to the financial crisis has been hampered by pre-existing financing gaps in the power sector. These countries already have a backlog of financing needs for necessary repairs to transmission and generation facilities and required capacity additions to address supply shortages. The pre-existing financing gap means that the cur- rent investment gap is quite large as compared with the size of the economy (table 1.2). For example, in Armenia, the transmission infrastructure is 45-years old. A total of 520 kilometers of transmission lines are in need of urgent reha- bilitation at a cost of US$80–100 million. In addition, a 600 megawatts supply gap will emerge when a nuclear plant retires in 2017 (World Bank 2010a). In total, Armenia has an investment gap for 2010–15 of almost US$6 billion, which is about half the size of the country’s gross domestic product (GDP). In Indonesia, tariff reforms were curtailed in late 2003, which hurt the bankabil- ity of electricity projects (ESMAP 2010a). As a result, a financing gap had emerged even before the financial crisis occurred. On the other hand, Romania’s almost US$15 billion investment gap is not out of line with the country’s overall GDP. In Sub-Saharan Africa, as elsewhere, the financial crisis exacerbated pre- existing financing challenges. A joint report by the New Partnership for Investment Needs and Financing Challenges 9 Box 1.1 Government Response to the Financial Crisis Ukraine—Government Response to the Financial Crisis Hurts Power Sector The financial crisis affected Ukraine’s economy through a large drop in GDP, currency depre- ciation, fall in exports, and tighter credit. In 2009, an 8.7 percent drop in demand delayed the onset of a power supply gap from 2015 to 2017. But government intervention focused on helping other economic sectors. To support state-owned coal mines, the government required power plants to purchase coal from state mines, which hurt the financial performance of the power plants. And distribution companies were hurt by the government-imposed morato- rium of tariff increases. Most commercial lenders and private investors lacked interest in the power sector before the crisis because of the poor regulatory environment. Future involvement now seems less likely because of how the financial crisis and government intervention have affected the financial performance of utilities. As a result, IFIs and bilateral donors remain the primary source of long-term lending to the sector. India—Fiscal Stimulus Package Helps Power Sector The global financial crisis did not have a substantial impact on India’s electric power infra- structure investments. India’s power sector resilience is attributed to its strong domestic demand fundamentals, broadening of the domestic private power developer base, greater dependence on domestic sources of debt funding, existence of strong sector-focused financ- ing entities, and appropriate monetary policy measures by the central bank to address liquid- ity problems. The fiscal stimulus packages in December 2008 and January 2009 played an important role as well in helping the power sector weather the financial crisis. The packages included government guaranteed funds for infrastructure spending and additional public spending on capital projects. Source: World Bank 2010; ESMAP 2010.

Calculated based on total investment needs. 10 A World Bank Study Africa’s Development (NEPAD) and the Organization for Economic Co-operation and Development (OECD) highlights the challenges African countries face in securing financing for the power sector (NEPAD-OECD 2009). The report finds a variety of impediments. On the financial side, there are high costs inherent to the energy sector, limited access to funding, poor or non-existent sovereign credit ratings, narrow domestic capital markets, and a lack of financial instruments like project bonds. On the regulatory side, there is a lack of independent or impartial regulators, lack of competition or open access to transmission and distribution networks, weak procurement laws, one-off rather than standard power purchase agreements, inefficient or non-transparent tendering, poor contract laws, and tariffs that do not provide for inflation or cost changes. On the capacity side, there is a lack of skills to manage PPPs, inadequate local judicial systems, and regional and sub-national regulatory frameworks that are not harmonized. Power Sector Operating Expenditures How about the power sector’s operating expenses? Evidence from past crises suggests that maintenance and operating expenditures are hit particularly hard, and this crisis is no different. Rising fuel costs and declining revenue are the main culprits. In countries that purchase fuel in foreign currency, such as Armenia and Kyrgyz Republic, fuel costs rose even higher than elsewhere as a result of a currency depreciation. In Romania, generation companies decreased their operating expenditures and employment to cope with declin- ing revenue from electricity sales resulting from a drop in demand (World Bank 2010a). However, in spite of the expected decline in the demand for infrastructure services, preliminary results from a simulation exercise show that maintenance needs will continue to increase. In fact, estimates to 2015 suggest that, assum- ing that new investment will occur though at a reduced pace, maintenance needs (in terms of GDP) in developing countries will be on average 2 percent higher than they would have been in the absence of the crisis, despite the fact that new investments needs will drop by about 12 percent because of the financial crisis and lower demand for power stemming from reduced GDP growth. This result underscores the need to safeguard maintenance resources to preserve the existing infrastructure stock as well as new investments (see SDN 2009). Many factors explain the resilience of investment in private electricity projects: • The demand (consumption) for electricity has grown faster than installed capacity in many developing countries in the past 15 years, creating a pressing need to expand generation capacity. In Vietnam, 3.75 gigawatts of capacity additions are required to restore reserve margins. In Indonesia, electricity demand is expected to triple by 2020. Investment Needs and Financing Challenges 11 • Many developing countries that have reformed their electricity sectors and created regulatory frameworks to put the sector on sound commercial footing have been able to attract private investment. For example, the Philippine power sector underwent major reforms in 2004 when the state-owned major power generator separated its generation and transmission assets. By the end of 2008, most large plants accounting for 48 percent of generation capacity had been successfully privatized (ESMAP 2010a). • Some countries have focused on creating packages to attract independent power producers. Prior to the early 2000 economic crisis, Egypt successfully introduced an IPP scheme, whereby privately owned power stations entered into long-term power purchase agreements with the country’s single buyer of electricity and also benefited from state guarantees (ESMAP 2010b). But the financial crisis stifled the momentum for this to occur. In Tunisia, the public utility generates 70–75 percent of the country’s power and monopolizes trans- mission and distribution. Despite a 1996 law allowing private operators to produce electricity under public concessions, only two IPPs operate to date. However, Tunisia has attracted major developers from Europe, Asia, and the Gulf Countries to undertake two planned IPP projects that will add 1.6 giga- watts of capacity from 2011 to 2016 (ESMAP 2010c) • Countries with power crises have resorted to short-term private solutions, such as rental power plants, to reduce the severity of blackout and power shortages (box 1.2). However, occasionally even rental power plants remain out of reach. Pakistan planned to resort to rental power plants as a quick-fix solution to the energy crisis, but was unable to secure any of the planned 2,250 megawatts of capacity in 2009 (ESMAP 2010d). In addition, old rental power plants faced natural gas shortages, forcing them to use expen- sive residual fuel oil instead. This led to greater fuel imports and loss of generation capacity. Given the financial crunch and all the incomplete energy projects, there is a risk that if economic recovery is faster than projected, there might be a mismatch between demand and supply. If that occurred, policy measures would be needed to boost, energy efficiency, phase out subsidies, and protect the most vulnerable consumers (IEA et al. 2010). Under-investment in a context of rapid demand growth has been a major cause of the power crisis. In some countries, supply shocks have exacerbated the situation. Supply shocks include droughts in East Africa; oil price, inflation which made it difficult for many West African countries to afford diesel imports; gas shortages owing to growing domestic demand and declining domestic pro- duction, which led to greater dependency on imported oil in Bangladesh and Pakistan; and conflicts that destroyed the power infrastructure in some fragile African states. In some countries, subsidies to the electricity sector have become a heavy burden for public finances. Electricity and petroleum subsidies repre- sented 3 percent of GDP in Pakistan in 2008. 12 A World Bank Study Box 1.2 Emergency Solutions to Power Sector Crises A common response to the immediate crisis is to tender short-term leases for energy power, ranging from six months to three years. Unlike conventional electricity generation projects, rental projects can be put in place in a few weeks or months. However, these plants can become a large fiscal burden. Given the preponderance of small diesel units, the cost has typically been US$0.20–0.30 per kilowatt-hour, exceeding by many times the cost of electric- ity from longer term sources. In 2005–09, developing countries, primarily those with power crises, implemented almost 2,000 megawatts of rental power plant capacity (see figure B1.2).

Investment Needs and Financing Challenges 13 How Do Climate Change Considerations Affect Investment Needs? Climate Change Mitigation and Adaptation: Overall Impact On top of conventional power needs, countries all over the world must grapple with investments to mitigate and adapt to climate change. But there is consider- able uncertainty about how much this will cost in individual countries, what measures can be undertaken in both the short and longer term, and how cost- effective specific interventions are in reducing emissions. Estimates of overall economy-wide investment needs range from US$170 to US$12,205 billion per year for mitigation and from US$75 to US$100 billion per year for adaptation over the period from 2010 to 2050 (table 1.3 and table B.1 in appendix B). The wide range reflects the uncertainty involved in making climate change projections and differing assumptions and methodologies. That said, most studies start by defining a baseline investment need for clean energy that is then supplemented with the incremental investment costs of achieving a lower carbon energy base, depending on alternative assumptions (related to the stabilization target, the pathway to stabilization, and the underlying develop- ment pathways of developing countries, including technological developments Table 1.3  Predictions Vary Enormously on Funds Needed for Mitigating GHG Emissions additional investment for GHG mitigation relative to business-as-usual or the reference Scenario Regional a Date Scenarios Energy sector Power sector distribution IEA world energy outlook b 2010 450 Policy scenario US$11.6 trillion (2010–30) Power generation: Energy 2010–35: 450 Scenario or (US$2,009) US$7.9 trillion (2 °C increase in global US$580 billion/year, US$2.4 trillion (2010–35) or (OECD+) temperature) US$18 trillion (2010–35) US$96 billion/year US$5.8 trillion (other or US$720 billion/year major economies) 2009 450 Policy scenario US$10.5 trillion (2010–30) Power generation: Energy 2010–30: 450 Scenario 45% of which in transport (US$2,008) US$5 trillion (OECD) (2 °C increase in global US$525 billion/year US$1.75 trillion (2010–30) US$3.1 trillion (other temperature) US$87.5 billion/year major economies) (28% higher than the Reference scenario) 2008 550 Policy scenario — Power generation: Power generation GHG concentration is (US$2,007) 2010–30: stabilized at 550 ppm US$1.2 trillion (2010–30) US$170 billion (other of CO2-eq US$60.0 billion/year major economies) US$890 billion (OECD+) 450 Policy scenario — Power generation: Power generation GHG concentration is (US$2,007) 2010–30: limited to US$3.6 trillion (2010–30) US$1.4 trillion (other 450 ppm CO2-eq US$180 billion/year major economies) US$1.6 trillion (OECD) (table continues on next page) 14 A World Bank Study Table 1.3  Predictions Vary Enormously on Funds Needed for Mitigating GHG Emissions (continued) Regional a Date Scenarios Energy sector Power sector distribution IEA energy technology perspectives 2010 BLUE scenario US$46 trillion (2007–50) Electricity sector: — Reduce CO2 emissions or US$1.1 trillion/year (US$2,008, including T&D) by 50% from 2005 by (1.9% of world GDP/year) US$9.3 trillion 2050 Power generation: US$6 trillion US$150 billion/year 2009 BLUE scenario US$45 trillion (2005–50) Electricity sector: — Reduce CO2 emissions 18% over baseline (US$2,005, including T&D) by 50% from 2005 by US$1.1 trillion/year US$2.9 trillion 2050 (1.9% of world GDP/year) Power generation: US$3.6 trillion (28%↑) US$80 billion/year 2008 ACT scenario US$17 trillion (2005–50) Electricity sector: — Bring global CO2 7% over baseline (254t) (US$2,005, including T&D) emissions back to US$400 billion/year (0.7% US$-1.1 trillion current levels by 2050 of world GDP/year) Power generation: US$0.7 trillion (6%↑) US$15.6 billion/year Source: World Bank data.

They also target holding global warming below the 2 degree threshold identified by the UN Intergovernmental Panel on Climate Change (IPCC) as financially and environmentally manageable. Impact of the Financial Crisis Most studies draw on a global GHG abatement cost curve first produced by McKinsey in January 2007 and revised in January 2009 (McKinsey 2007, 2009). It has formed the basis for discussing the cost of existing mitigation levers, such as greater energy efficiency and various types of renewable energy. In the case of Mexico, Latin America’s largest fossil-fuel consuming country, a World Bank low-carbon country study shows that a variety of levels could be used to sharply cut GHG emissions, especially in agriculture and forestry, trans- port, and electric power sectors (box 1.3). In August 2010, McKinsey updated the abatement cost curve to reflect the impact of the global financial crisis (McKinsey 2010). The new curve shows that business-as-usual (BAU) emissions projections for 2030 have decreased by 6 percent, owing to the 2008 global financial crisis and slowdown in economic growth. The biggest drop, 6–11 percent, is in emissions projections for devel- oped countries, while projections for China and the rest of developing Asia Investment Needs and Financing Challenges 15 Box 1.3 A Low Carbon Growth Path for Mexico Over the past two years, Brazil, China, India, Indonesia, Mexico, and South Africa have initiated studies—with the World Bank’s Energy Sector Management Assistance Program (ESMAP)—to assess development priorities in conjunction with GHG mitigation opportunities, and to esti- mate additional costs and benefits of lower carbon growth. Besides strengthening country ownership of mitigation strategies, the studies have already provided two valuable outputs, in terms of a framework for establishing low carbon pathways and in terms of a knowledge and data set, which can be used as a toolkit for other countries to reduce GHG emissions and lower mitigation costs. In the case of Mexico, Latin America’s largest fossil fuel-consuming country, its study sheds insights on prospective low carbon “wedges�—which are composed of specific inter- ventions across the key emission sectors (electric power, oil and gas, stationary energy end- use, transport, and agriculture and forestry). Three criteria were used to select interventions Figure B1.3  Targeted Interventions Would Sharply Lower Emissions 1,200 1,000 e elin Bas Emissions (MT CO2e/year) 800 600 400 MEDEC emissions 200 0 2008 2015 2020 2025 2030 Year Agriculture and forestry Electric power Energy end-use Oil and gas Transport Source: World Bank data.

The study did not assume a value for carbon mitigation but rather produced a “cost of carbon� as an output, calculating the net present value as of 2008 of the direct economic costs and benefits of each intervention between 2009 and 2030 to reach the “net costs� of reducing emissions. Under the baseline scenario, total CO2e emissions would grow from 659 Mt in 2008 to 1,137 Mt in 2030. But under a low carbon growth path (which includes 40 interventions), total CO2e emissions would drop by about 477 Mt in 2030 relative to the baseline—which would be virtually the same as in 2008, despite significantly higher GDP and per capita income. This estimate is still conservative, in that other interventions and technological change are not considered. The key sector is agriculture and forestry, where interventions would include reforestation, commercial plantations, and measures to reduce emissions from deforestation and forest degradation. The next most important is transport, followed by electric power, energy end-use, and oil and gas. were revised upward by 1–2 percent (figure 1.5). BAU emissions projections from the power sector globally decreased by 5 percent. Of course, reduced BAU emissions will help countries achieve their reduction targets, but the credit-constrained economic environment will likely make financing of abatement measures more challenging (McKinsey 2010). The revi- sion suggests that abatement potential remains stable at 38 gigatons of CO2 equivalent in 2030 through technical measures costing below €80 (US$114) per ton of CO2 equivalent (McKinsey 2010). Climate Change Mitigation and Adaptation: Power Sector Impact How about the additional cost of climate change for the power sector? The International Energy Agency (IEA) provides estimates of the impact of carbon mitigation activities on power sector investment in two annual reports, the World Energy Outlook (WEO) and Energy Technology Perspectives (ETP). The key dif- ference between them is that the WEO makes projections only for the 2010–30 period, while ETP expands the period to 2050 (table 1.3). The estimates show that reducing CO2 emissions by 50 percent from 2005 levels by 2050 will require investments in the electricity sector (from 2010 to 2050) of US$9.3 trillion—40 percent higher than in the baseline scenario (BLUE Scenario of ETP 2010). Of this amount, investment in power generation accounts for US$6 trillion, transmission for US$1.7 trillion, and distribution for US$1.6 trillion. Interestingly, the additional investment in the whole power sec- tor is expected to be smaller than what would be expected from the increased investment in power generation alone. This is mainly because impacts from Investment Needs and Financing Challenges 17 Figure 1.5  The Financial Crisis Resulted in Lower GHG Emissions V2.1 BAU emissions Change from V2.0 Change from V2.0 GtCO2e per year; 2030 GtCO2e per year; 2030 % North America1 8.2 –1.0 –11 Developed countries Western Europe2 5.8 –0.4 –6 experience the largest decline OECD Paci c 2.5 –0.3 –11 Africa 3.6 –0.5 –12 Latin America 6.5 –0.4 –5 Many developing countries are also India 4.7 –0.3 –6 signi cantly a ected Middle East 2.9 –0.3 –9 0 0 Some developing Eastern Europe3 3.9 countries are Rest of developing 0.2 2 expected to grow 8.8 even faster, with Asia 0.1 1 upward revisions in China 16.7 GDP growth –1.5 –44 Revision of external Global air & sea 1.8 forecasts for sea sector Total 66 –4 –6% 1.

By reducing demands for electricity, less investment will be required for networks, mainly distribution, compared with the reference scenarios. As for the energy sector—which includes industry, transport, and buildings next to the power sector—the IEA estimates that there will need to be an additional investment of US$1.1 trillion per year, which is 1.9 percent of the 2009 world total GDP (IEA 2010). On a regional basis, OECD countries are expected to bear the largest share, especially before 2020. Quantitatively, the estimated size of the impact depends largely on the design of scenarios and associated assumptions on baseline emissions, projected future international climate agreements and national policies, and mitigation trajectories. Adaptation The power sector will play a key role in a country’s ability to adapt, because without a well-functioning power sector that gives the entire population reli- able access to electricity, many of the technologies that facilitate adaptation in the agriculture, infrastructure, and health sectors cannot be implemented. Estimates of adaptation investment needs vary greatly because of differing methods, levels of inclusion (impacts and regions analyzed), and assumptions about the rate of climate change and time preferences (table B.1 in appendix B). 18 A World Bank Study Box 1.4 Cost of Developing Countries Adapting to Climate Change So how much would it cost the developing countries to adapt to climate change? A recent World Bank study puts the total at between US$75 to US$100 billion a year by 2050, assum- ing a temperature rise of about 2 °C. The bulk of the funds would go for infrastructure, protec- tion of coastal zones, and water supply and flood protection. On a regional basis, the largest burden would fall on East Asia and Pacific, followed by Latin America and the Caribbean, and the lowest burden would fall on the Middle East and North Africa. But Africa would have the highest cost relative to GDP. The study looks at two climate change scenarios to capture as large as possible a range of model predictions yielding extremes of dry and wet climate projections. It finds that in a “drier� one, costs would be significantly lower than in a “wetter�one, largely because the latter would lead to more infrastructure deterioration, which would steeply increase investment needs. But both scenarios show costs increasing over time, although falling as a percentage of GDP—suggesting that economic growth lowers vulnerability to climate change. Source: Economics of Adaptation to Climate Change 2009. A 2007 study by the UN Framework Convention on Climate Change (UNFCCC) estimates global investment needs at US$50–170 billion annually between 2010 and 2030 (table B.1 in appendix B). Based on the McKinsey global GHG abatement cost curve, Project Catalyst (2009) estimates that devel- oping countries need around US$13–25 billion annually between 2010 and 2030 to adapt to climate change. As part of the preparations for the Copenhagen conference on extending the Kyoto Protocol, the World Bank was asked to estimate the cost of adapting to climate change in developing countries from 2010 to 2050. The Economics of Adaptation to Climate Change (EACC) study makes use of panel data for more than 160 countries for 1960–2005, projecting infrastructure demand at five year intervals from 2010 to 2050. The cost of adaptation is estimated at US$75–100 billion annually between 2010 and 2050 and is divided into (1) the net increase in the cost of constructing infrastructure under some baseline scenario; (2) the net change in demand for infrastructure owing to higher temperatures or differ- ent patterns of precipitation; and (3) the net change in the costs of operating, maintaining, and replacing infrastructure (box 1.4). Sources of Financing of Investment for Conventional Power So who will pay for the needed investments in the power sector, beginning with investment needed for conventional power. Keep in mind that investment costs for power projects can easily run into billions of dollars, and the payback period can extend beyond 10 years. Thus, it can be difficult even for well-performing Investment Needs and Financing Challenges 19 power companies to secure financing, let alone companies in poorly regulated environments. In theory, governments and power companies can finance invest- ment in generation, transmission, and distribution through a variety of ways, from local or international banks and private equity to international financial institutions and bilateral donors. Exactly how much is available and from where typically depends on the political stability of the country, the development of the financial sector, and the regulatory and tariff regime of the power sector. But the global financial crisis has altered the picture, with traditional funding sources to public power projects—including government budgetary transfers, internal cash generation, commercial banks, and bond markets—drying up. Government budgetary transfers have diminished owing to competing expendi- ture priorities. Foreign bank loans have declined and become more expensive, while local banks are liquid but constrained by single borrower limits. Most top tier foreign banks have capped funding levels, which will hurt foreign currency borrowing programs of state-owned power utilities that are seeking private finance beyond multilateral funding. And public aid flows from bilateral and multilateral donors and international financial institutions (IFIs) have decreased. At this point, state-owned entities (SOEs) are struggling to cope with higher borrowing costs. Spreads over global benchmarks have widened for SOE bor- rowing, and the spreads are also higher for local loans. When combined with local currency devaluation, it has led to an erosion of SOE borrowing capacity. Most SOE borrowings are in the form of bilateral and multilateral hard currency loans. Combined with floating rate local and foreign currency loans, unhedged foreign currency and interest rate exposure could impair SOE ability to service debt. Sector lending limits are being approached. In Indonesia, state-owned banks are willing to exceed these limits but only in return for explicit govern- ment guarantees. In some countries, commercial banks preferred to extend credit to public sector entities over private sector projects during the financial crisis. In India, power entities owned by the state governments did not face many challenges in securing debt financing, even though they are known for their relatively weaker financial profile as compared with power entities that are privately owned (ESMAP 2010d). Sources of Financing of Investment in Period of Crisis Recourse-Based/Own Funds. Power sector companies with strong balance sheets and robust cash flows were able to finance their investments on a recourse basis (that is, on the strength of their balance sheets). This was the case for government-owned power sector entities in India. However, the cost of bor- rowing went up by about 75–100 basis points in tandem with the increase in prime lending rates of banks in the immediate aftermath of the financial crisis (ESMAP 2010d). In many developing countries, the regulatory regime of the power sector does not allow for full and predictable recovery of capital expenditure costs (including 20 A World Bank Study financing costs) over several years. The lack of reliable revenue means that power sector entities have a relatively weaker financial profile, ruling out financing through own funds. Where electricity tariffs remain below cost-recovery levels, power companies are unlikely to be able to borrow at competitive rates either through the bank credit route or the bond finance route. Revenues have also been hurt by rising fuel costs, and in some cases, government intervention. In Armenia, the govern- ment waived the return on assets for state-owned utilities for 2009 and 2010, limiting revenues available for investment. In 2010, the Romanian government reduced the profit available for reinvestment from 40 percent to 10 percent for Transelectrica, the transmission and system operator (World Bank 2010a). Governments in many countries recognize the need to raise electricity tariffs to keep power companies running and make financing power sector projects more attractive. But they must gauge the level of cost pass-through consumers can bear in an economic crisis. As external financing became unavailable, some SOEs drew upon their cash reserves to fund capital investment. For example, a large SOE in the Vietnam power sector saw its cash balance fall during the first nine months of 2008 despite liquidation of its short-term investments to offset the contracting debt market. Large SOEs have shown lower levels of tangible asset formation during the second half of 2008 and have had to slow construction on projects. International Commercial Banks. Loan syndication remains a serious issue. Most top-tier foreign banks are focusing on lending to well-prepared projects offering significant risk cover, and many second-tier banks are unwilling to take any significant emerging country risk without an extensive security package or credit enhancement. This is the case in Bangladesh, where syndication markets dried up during the financial crisis. Since the beginning of the crisis, interest margins have multiplied by at least two or three times because of higher liquidity costs for the banks and reassessed risk premiums (ESMAP 2010e). In China, real interest rates have increased from a negative 0.1 percent in 2007 to a positive 6 percent 2009, and in Argentina, from a negative 2.8 percent to a positive 5.2 percent—although in India, rates have gone down from 6.9 percent to 4.3 percent (table 1.4). In addition, maturities have shortened, with project finance tenors increasing from less than 10 years, mostly through “mini perms,� which allow for durations of around 12 years. In Vietnam, for example, a large independent power pro- ducer has seen maturities increase by four years for its foreign currency debt, resulting in higher debt service requirements. In general, all deal parameters have tightened: reduced leverage (up to 25–30 percent equity instead of 20 percent for a typical power project), higher upfront fees, tighter coverage ratios, stricter covenants, and requests for reinforced sup- port from host governments (ESMAP 2010e). For many countries—such as those in the Middle East and North Africa—risk mitigation coverage from devel- opment financial institutions, export credits, or the insurance market is a must. Investment Needs and Financing Challenges 21 Table 1.4  Real Interest Rates Have Typically Risen pre- and postcrisis real interest rates, in percent 2007 2008 2009 Argentina –2.8 0.3 5.2 Armenia 12.7 8.0 17.1 Bangladesh 8.6 7.0 7.6 Bolivia 0.5 3.2 15.1 China –0.1 –2.3 6.0 India 6.9 6.2 4.3 Kenya 7.6 1.9 7.6 Kyrgyz Republic 9.1 –1.9 20.5 Nigeria 11.6 4.1 19.1 Paraguay 13.4 11.2 28.4 Philippines 5.5 1.2 5.9 Romania 0.3 3.1 10.1 United States 4.5 2.8 2.3 Source: World Bank 2011. In Vietnam and Indonesia, where uncovered loans are no longer a possibility, sovereigns are reviewing their ability to take on contingent liabilities on behalf of their SOEs. Export credit agencies. Export credit agencies are critical in many deals, since they allow for loans at relatively unchanged margins with long maturities, which are difficult to find in the commercial market (ESMAP 2010e). Maturities can reach up to 12 years for fossil fuel power plants and up to 18 years for renewable energy and nuclear plants. While banks have increased their margins on these agencies’ covered loans, they are still much lower than for pure commercial deals. International financial institutions. The dramatically decreasing appetite of commercial banks for long-term financing in non-investment grade or low- investment grade countries makes international financial institutions (IFIs) espe- cially valuable for private projects (ESMAP 2010e). They can provide additional funding and help more banks to join deals through IFI coverage schemes. IFI funds for private projects are more expensive than before the crisis, but remain much less costly than funds from commercial banks. IFI funds now cost typically 200–250 basis points for 10–15 years, up from 100 to 125 basis points before the crisis. Currently, commercial banks provide funds for over 400 basis points, provided they accept to provide funds beyond 7–10 years (ESMAP 2010e). The financial crisis has not limited IFI’s abilities to finance investments in the power sector nor has it decreased power sector companies’ appetite for conces- sional financing (World Bank 2010a). However, tightened fiscal space may limit governments’ ability to borrow. State budget deficits in each of the countries analyzed in these studies are expected to remain above precrisis levels for the next several years. Local Banks. In most developing countries, the local banking market is ill equipped to provide long-term finance beyond five to seven years. Larger loans 22 A World Bank Study require syndication among multiple local lenders, but the local market is often unable to absorb multiple large transactions concurrently (ESMAP 2010f). In Pakistan and the Philippines, the exposure of local banks to the power sector is too high to provide further credit to the sector. In Tunisia, owing to the limited size of Tunisian banks, it would be difficult for the local banking system alone to finance project amounts of several hundred million dollars (ESMAP 2010c). Even in countries with a relatively well developed banking sector, local banks are unable to finance large power sector projects because of a shortage of for- eign currency lending. In Morocco, the banking sector is well developed with structural excess liquidity, the electricity sector is seen as a good risk by the local banks, and long maturities (beyond 12 years) are still easily available on the local market. However, there is a limited availability of foreign currency on the local market. Thus, the long-term (15–18 years) foreign currency loans that will be needed to finance part of the upcoming IPPs must be made by international banks, export credit agencies, and IFIs. Bilateral Donors. For many developing countries, donors remain the primary source of financing for the power sector, but they are capping exposure limits and lowering maturities. Russia, China, and India are active bilateral donors because of their pre-existing political and economic ties to recipient countries and their expertise in working in developing countries. • Russia is active in neighboring East Central Asian countries, such as Armenia, the Kyrgyz Republic, and Ukraine through loans or joint ventures between Russian companies and governments • China is funding the 360 megawatts expansion of the Kariba North Bank hydropower plant in Zambia, along with the Development Bank of Southern Africa. The China-owned Sino Hydro Corporation is the sole project con- tractor, taking full responsibility for construction, including the supply of materials and labor (NEPAD 2009). Here, the bilateral donor has the option of importing labor and supplies to construct the power plant, thereby reduc- ing some of the risk if forced to hire and buy locally. • India Eximbank is funding a US$50 million loan for Zambia to build the 150 megawatts Itezhi-Teszhi hydro power station, a joint venture between Zesco and Tata Holdings (NEPAD 2009). The project is expected to be operational by 2012. Private Equity. Private investment is a possible source of financing for power projects, but it is harder to secure now. In Romania, many private investors were interested in renewable energy as well as thermal energy projects. Since the crisis, interest in thermal projects has waned, as the sector is restructuring, but interest in renewable energy projects continued owing to the perceived regulatory stabil- ity of EU regulations and the green certificate scheme (World Bank 2010a). In the Philippines, privatization of the National Power Corporation (NPC), the major state-owned utility, began in 2004, but has slowed because of the Investment Needs and Financing Challenges 23 financial crisis. The sale of most remaining NPC generation assets has failed, such as the privatization of Calaca worth US$748 million (ESMAP 2010a). The risk allocation among project counterparts is important to secure funding—with developers wanting to pass more risk to governments, at the possible expense of profitability (ESMAP 2010e). Projects with more demand uncertainty, such as those with a partial off-take agreement or export uncer- tainty, are less competitive in accessing project finance. Willing lenders, if any, will put a risk premium on such projects, which translates into higher electricity tariffs (ESMAP 2010e). Bond Markets. Power companies have turned to local bond markets to raise finance, but these markets are often not a viable alternative because they are largely illiquid and offer relatively short maturities. Access to global bond mar- kets is limited to creditworthy SOEs, of which there are few, and even then, the parameters are tighter. In Peru, Kallpa, a private generator, was able to reach financial closure in 2009 for a US$400 million thermoelectric project, using a project finance scheme (World Bank 2010b). However, Kallpa had to increase the equity con- tribution to 30 percent (from 25 percent precrisis) for a US$105 million, 10-year term loan. It also issued corporate bonds in the domestic market for US$172 million, 12.5 years, and a fixed rate of 8.5 percent, which was about 200 basis points above rates of similar bonds issued in mid-2007 by other large generators (World Bank 2010b). Sources of Financing of Investment for Climate Change When it comes to financing investment for climate change mitigation, there are additional sources on top of the traditional ones available for conventional power sector projects. Renewable energy and energy efficiency projects have access to carbon market finance and subsidies or feed-in tariffs. In addition, multilateral donors, IFIs, and private investors may prioritize investment in renewable over conventional power projects. However, renewable energy projects tend to be more expensive and more risky than conventional power projects. Given the huge amounts needed for coping with climate change, where will this money come from? Project Catalyst (2009) estimates that of the €65–€100 billion (US$95–146 billion) annual investment needs for developing countries from 2010 to 2020, about half could be supplied by the European Union Emission Trading Scheme (ETS) markets (figure 1.6). Up to 80 percent of the funds would go toward mitigation activities with the remainder earmarked for adaptation activities. A report by the UN Secretary General’s High-Level Advisory Group on Climate Change Finance, which explores sources for raising US$100 billion per year from 2020 for climate change, suggests the financing could come from public funds, carbon market offsets, international private investment, and mul- tilateral development banks (IEA et al. 2010). It concludes that raising this 24 A World Bank Study Figure 1.6  Potential Sources of Climate Change Financing for Developing Countries Financing needs and sources assuming 25% caps in developed countries 10–20 65–100 10–15 ETS auction revenues could be partially used Annual average 2010–20, rounded for international AAU purchases and 5–15 government offset purchases for non ETS sectors 55–80 to nearest Û5 billion 5–20 45–50 10–20 4–8 22–31 Mitigation Adaptation Total Direct Carbon ETS Other Internat- Concess- Public need carbon market auction public ional ional debt fiscal markets inter- revenues and inter- transport revenues ventions national levies sources ETS markets Climate change financing sources Source: Project Catalyst 2009. Note: Estimates based on the McKinsey global greenhouse gas abatement cost curve (McKinsey 2009). amount is feasible, but not easy, and very unlikely if it is understood to refer to public funds only. Such findings were confirmed by a new report recently submitted to the Group of 20 (World Bank 2011). Public Funds. Public funds, mainly through public carbon market revenues, could supply about US$50 billion per year in climate change financing to developing countries. Based on a carbon price of US$25 per ton in 2020, flows to developing countries might include US$30–40 billion from auctioning all domestic rights to emit (or taxing carbon), assuming 10 percent of total reve- nues are allocated to developing countries. If broad carbon pricing is not fea- sible, an alternative may be provided by “feebates� imposing taxes (fees) on relatively emission intensive firms or on products with low energy efficiency. In addition, taxes on international aviation and shipping could supply US$10 billion, assuming 33–50 percent are earmarked for developing countries (who can also keep their own revenues from this source). Other instruments, such as redeployment of energy subsidies or a financial transaction tax, could amount to US$10 billion. Actual estimates of 2020 revenue potential for new public instruments are sensitive to many assumptions, particularly the carbon price and the share allocated to international climate finance. Despite the recent slowdown in market activity, carbon markets showed resilience to the global financial crisis, registering US$142 million in 2010, US$2 million below the record achieved in 2009, but still more than twice the 2007 level and 6 percent higher than in 2008 (figure 1.7). The EU Emission Trading Scheme (ETS) accounts for the bulk of the activities. Carbon Market Offsets. These offsets could provide about US$20–100 bil- lion in flows to developing countries, according to World Bank (2011) estimates, Investment Needs and Financing Challenges 25 Figure 1.7  Carbon Markets Held up during the Financial Crisis 140 120 100 US$, billions 80 60 40 20 0 05 06 07 08 09 10 20 20 20 20 20 20 Year EU ETS allowances Other allowances Other o sets Primary CDM Secondary CDM Source: World Bank 2011.

Here, offsets refer to private entities or governments in devel- oped countries purchasing project-based offsets (that is, certified emission reduction credits [CERs]) from private entities in developing countries, such as through the Clean Development Mechanism (CDM). However, the US$7 billion invested each year so far through the CDM has been concentrated mainly in emerging market economies (EC 2011). In fact, about 91 percent of CERs were earned in only four host countries: China (57 percent), India (15 percent), the Republic of Korea (11 percent), and Brazil (8 percent) (UNFCCC 2011). The European Commission is committed to achieving a better geo- graphical balance and increasing finance for the poorest countries (EC 2011). Private Investment. The private sector can also play a key role in financing energy efficiency investments. In fact, the AGF and World Bank (2011) identify international private investment as essential for the transition to a low-carbon and climate-resilient future. A carbon price of US$20–25 could generate around US$10–20 billion in private net capital flows. In addition, US$30–50 billion could be generated in increased carbon market flows, delivering around US$10 billion of net transfers. Assuming that energy is appropriately priced, much of this funding is expected to come from consumers and private sources. That said, public funding may be required to address market barriers like information gaps and to facilitate a buy-down in transaction costs. 26 A World Bank Study As for adaptation, the expected role and sequencing of private finance is even trickier. Many of the activities will need to be embedded in development pro- grams, ensuring that future development investments are sufficiently “climate proofed.� The private sector, in some highly exposed areas, might be expected to cooperate. At this stage, however, few private investors feel they have the information to effectively factor future climate risks into decision making. The public sector would be left with a leading role, at least in the early stages of expansion: a massive public investment push, coupled in the short term with appropriate subsidy mechanisms to offset high initial prices and targeted at the most promising technology options. A key factor inhibiting international bank participation in renewable energy in emerging countries is that the regulatory risk, which is seen as more critical in renewable than conventional energy, is often considered too high (ESMAP 2010e). A 300 megawatts wind power project in Ukraine’s Crimea region was delayed because a foreign equity sponsor pulled out in 2009 (World Bank 2010a). In Armenia, small hydropower projects have become less attractive because of increased financing costs, and some commercial banks, which committed to IFI-funded small hydropower projects, are seek- ing co-financing sources in Armenian drams (World Bank 2010a). However, in Romania, investments in renewable energy are continuing because the market is perceived as less risky than the conventional energy one thanks to EU requirements and the green certificate trading scheme (World Bank 2010a). But investments in conventional thermal projects have been delayed or cancelled as investors wait to see how generation restructuring will affect the sector (World Bank 2010a). Multilateral Development Banks. Finally, for every US$10 billion in paid-in capital, multilateral development banks could deliver US$30–40 billion in gross flows, resulting in US$11 billion in net flows to developing countries, according to AGF estimates. However, development banks were also hit by the global financial crisis. In Jamaica, the Inter-American Development Bank, along with PetroCaribe, scaled back its funding of non-wind renewable energy and energy efficiency programs from US$150 to US$20 million over 2010–17 (World Bank 2010b). Investment Trends in Renewable Energy Overall, around US$257 billion was invested globally in renewable energy in 2011. Of that, China led the way (for the third consecutive year) with new financial investments of US$52 billion (figure 1.8). Ambitious, mandatory targets for wind and solar power and the ample availability of credit in China have been the primary engines of that nation’s clean energy growth. The United States came in second at about US$50 billion,and Italy managed a distant third, thanks to a newly designed solar feed-in tariff and a major Initial Public Offering (IPO) by Enel Green Power, which raised US$0.5 billion in 2010.

Among developing countries in top world positions, Brazil and India stand out. But while Brazil’s renewable investment was characterized by a subdued performance, mainly owing to consolidation in the biofuel segment, India’s grew strongly, supported by an accelerated depreciation tax break (expected to be reformed in 2012), new solar mission, and launch of Renewable Energy Certificates. Mexico’s renewable investments increased by fourfold from 2009, reaching more then US$2.3 billion, thanks to new funding for wind projects. Egypt, the top country in the Middle East and North Africa region, achieved renewable investments of over US$1.3 billion, owing to large solar thermal and wind projects. Kenya, the top performer in Sub-Saharan Africa, invested US$1.3 billion—up from virtually zero before—on a diversified basis (wind, geothermal, small hydro, and biomass). Stimulus packages of countries leading efforts in clean energy also included a substantial component of clean energy, both in absolute and percent of GDP terms (figure 1.9). At the height of the global financial crisis, the United States announced a US$68 billion stimulus package, and China, a generous US$46 billion. Which types of renewable energy are drawing the most new investment? Solar power leads the way, growing at an exponential rate in 2011, mainly fueled by growth in developed countries, which recorded US$90 billion more investment than developing countries (figure 1.10). Wind power comes in second—mainly driven by developing countries—although investment is down from the peak recorded in 2010. Biomass comes in third, followed by biofuel, small hydro, geothermal, and marine. 28 A World Bank Study Figure 1.9  Recent Stimulus Packages Favor Green Investments stimulus packages, 2009 70 3.5 60 3.0 50 2.5 US$, billions Percent 40 2.0 30 1.5 20 1.0 10 0.5 0 0.0 es m da 7 ly a a y n n ey re an in -2 ai pa Ita at do rk na Ch Sp Ko EU rm Ja St Tu ng Ca h d Ge of Ki ut ite st d So Un Re ite Un Countries Stimulus Funding (US$, billions) Stimulus funding (% GDP) Source: Bloomberg New Energy Finance.

For many developing countries, investment is hampered by both the lack of financial viability for clean carbon technology packages and planning approaches that often fail to appropriately value and integrate clean carbon technologies. The menu of financing sources available to renewable energy projects depends on the maturity of the technology involved—whether it’s “pre-commercializa- tion� (like a carbon capture and storage), “not financially competitive� (like renewable electricity, such as wind), or “mature�(typically energy efficiency, such as lighting (CFLs)). Investment Needs and Financing Challenges 29 Phasing Out Energy Subsidies For some countries, phasing out energy subsidies could become a vital source of financing for power sector improvements and climate change mitigation and adaptation activities. These subsidies, which consume billions of dollars in many countries are no longer affordable for many state governments, but removing them right now is tough politically. In Uzbekistan, energy subsidies amounted to over 30 percent of GDP in 2010 (EIA 2011; IEA, OPEC, OECD and Word Bank 2011). The most heavily subsidized item is oil, followed by natural gas and electricity. As these subsidies are phased out, countries will realize numer- ous benefits. Efficiency gain. Phasing out subsidies would achieve efficiency gains by removing market distortions. Subsidies that artificially lower energy prices result in an economically inefficient allocation of resources and market distor- tions, encourage wasteful consumption, exacerbate energy-price volatility by blurring market signals, incentivize fuel adulteration and smuggling, and under- mine the competitiveness of renewables and more efficient energy technologies (IEA 2010). Environmental benefit. Phasing out subsidies would help climate change. Market-based instruments for mitigation include putting a price on carbon, either through a carbon tax or an emissions trading scheme. But energy subsidies essentially reward activities that produce carbon emissions. While the EU emissions trading scheme (EU ETS) puts a price on carbon, many countries subsidize energy, including Russia, India, non-EU eastern European countries, and oil-exporting countries. But just removing these subsi- dies, as figure 1.11 shows, could reduce GHG emissions in some of these coun- tries by over 30 percent by 2050, and reduce global emissions by 10 percent (IEA et al. 2010; OECD 2009). This would happen because in the absence of these subsidies, demand would fall, in turn, lowering the price of fossil fuels. However, the fall in emissions would be somewhat offset by an anticipated increase in emissions in developed countries, as demand rises in response to lower fossil fuel prices. The IEA (2010) estimates that removing energy subsi- dies would decrease CO2 emissions by 5.8 percent or 2 gigatons (Gt) by 2020, cutting primary energy demand by 5 percent and oil demand by 4.7 million barrels per day, or one quarter of current U.S. demand. Economic benefit. Phasing out energy subsidies would also alleviate the financial position of cash-strapped governments. For fossil-fuel importing coun- tries, subsidies place a significant fiscal burden on state budgets. During fossil fuel price spikes and unfavorable exchange rate fluctuations, the burden can become quite large. In Indonesia, higher international oil prices and a recovery in consumption led to a peak in energy subsidies at 4.5 percent of GDP in 2008, while public capital expenditure and spending on social programs amounted to only 1.5 percent and 1.2 percent of GDP, respectively (Mourougane 2010). For fossil fuel-exporting countries, subsidies quicken resource depletion, which can reduce long-term export earnings (IEA et al. 2010). 30 A World Bank Study Figure 1.11  Removing Energy Subsidies in Non-OECD Countries would cut GHG Emissions % change in emissions compared to baseline 20 10 Percent change in emissions 0 –10 –20 –30 –40 –50 No ex l b tri rn sia tri ing a na ld w ali l al nd da es an TA xl ld i az di es a or or un te at ne hi ap na EF Oi Rus Ze a a es d In un rt Br w W an St co eas C An co xpo Ca J n us e An d th n- r pl an U ite Ne ust l-e pe -E of 27 Un ro Non A st EU Re Countries and groups of countries Eu 2020 2050 Source: OECD 2009.

Annex 1 countries are countries that have agreed to reduce their greenhouse gas emissions under the Kyoto Protocol. They include most OECD member states and some countries from Central and Eastern Europe in transition to a market economy. The funds previously allocated for energy subsidies can instead be spent on poverty-alleviation programs. In fact, given that rates of access to basic energy services are quite low in many developing countries, energy subsidies can be regressive: funds allocated to subsidize existing consumers who can afford to pay cost-reflective prices could be better used to favor the poorest without access to energy services. Household surveys show that gasoline and transport fuel subsidies accrue mostly to the richer income quintiles. An important condition for successful subsidy reform is the credibility of the government’s commitment to compensate vulnerable groups and to use the funds freed from subsidy reform for more welfare enhancing activities. Policy tools to protect the poor include lifeline rates, which generally perform better than universal subsidies, and cash transfers. Use of transitional arrangements and short-term measures to alleviate the impact of tariff increases on the poor can act to protect low-income groups at the time of the policy change (Vagliasindi, forthcoming). Against this backdrop of some slow down of PPP investment in the power sector in the wake of the recent financial crisis and enormous sums needed to Investment Needs and Financing Challenges 31 meet the expected growing demand for power—especially in the developing world—and to cope with climate change, what is the best way to attract PPPs? Chapter 2 explores this issue, asking which incentives matter most for convinc- ing PPPs to invest in both conventional and renewable energy sources and which incentives influence the level of investment.

CHAPTER 2 How PPPs Are Faring Globally The global picture for energy investment is changing—and rapidly. In 2008, for the first time, renewable energy (including large hydro) attracted more power sector investment globally than fossil-fuel based technologies, according to UNEP (2011). Moreover, renewable sources of energy are expected to triple by 2035, according to the International Energy Agency’s New Policies scenario (IEA 2010). This growth is being driven by an alignment of global factors (1) a rapid rise in energy demand from emerging economies such as China and India; (2) increased competition for energy resources; (3) geopolitical tension and energy security concerns; (4) rising oil and gas prices; and (5) the entry into force of the Kyoto Protocol in early 2005, along with a higher political interest in climate change. In recent years, global investment in renewable energy has jumped from around US$23 billion in 2004 to around US$114 billion in 2007 and following a drop after the global financial crisis, climbing back up to a peak of almost US$173 billion in 2011 (figure 2.1). If research and development programs are included global investments equal US$257 in 2011, of which 65 percent were generated from developed countries and 35 percent in developing countries. At this point, renewable energy still represents a marginal percentage of the world’s generation mix—in terms of global installed capacity, about 9 percent as of 2011 (excluding large hydropower), although up from around 5 percent in 2004 (figure 2.2). But its share in total new capacity additions (including hydropower) has grown exponentially, from 10 percent in 2004 to 44 percent in 2010. How is this energy picture likely to evolve in terms of the level and com- position of investment? The change would be drastic if a move toward low carbon solutions is implemented through an increasing proportion of renew- able energy. Most renewable sources of energy cost more than energy from fossil fuels, typically because of higher upfront capital costs, although these costs are rapidly falling. Once projects have begun, operational costs are lower than for energy fossil fuels—for example, wind and solar, do not have a fuel cost or fuel price volatility to manage. Renewable energy project financing also involves longer financing structures. Before the global financial crisis, 35   36 A World Bank Study Figure 2.1  Global Investment in Renewable Energy Has Risen Sharply 60 50 Financial crisis 40 Kyoto protocol US$, billions 30 20 10 0 t d d h t d d h t d d h t d d h t d d h t d d h t d d h t d d h 1s 1s 1s 1s 1s 1s 1s 1s 4t 4t 4t 4t 4t 4t 4t 4t 2n 3r 2n 3r 2n 3r 2n 3r 2n 3r 2n 3r 2n 3r 2n 3r 2004 2005 2006 2007 2008 2009 2010 2011 Source: Bloomberg New Energy Finance. maturities extended to 15 years or more to repay upfront loans, through income stemming from the project’s power generation. This makes renewable energy power projects exposed to longer term risk, including the policy and regulatory incentive environment.

How PPPs Are Faring Globally 37 Given the higher costs and risk of renewables, companies—particularly in the private sector—are unwilling to invest unless they are required to or offered economic and financial incentives to do so (such as through price support mechanisms). This situation matters because private investors are needed to supplement public sector investment, especially given the addi- tional daunting tab that will come from investments to cope with climate change (mitigation and adaptation). Furthermore, the biggest share of future investment will be needed in the developing world, where demand for power is expected to grow exponentially in response to development and population growth. What is the best way to encourage public-private partnerships (PPPs) in the power sector in developing countries? To shed more light on this issue, we undertook a study to gauge which factors encourage private investment in electricity generated by fossil fuels (oil, coal, and natural gas) and renewables (hydro, wind, waste and geothermal). We used an econometric analysis, cover- ing 105 developing countries from 1993 to 2008. We grouped these factors into three areas: sectoral and economy-wide governance, long-run environ- mental sustainability drivers, and short-run crises and long-term economic fundamentals. This chapter begins with a look at how PPP investment in the power sector is changing and what we know already about the role of governance and its impact on performance. We then explain how the study was done and our key findings. The highlights are: • Support mechanisms, like feed-in tariffs, are crucial for attracting investors in generation, but they could play a bigger role in affecting the level of investment • Regulatory certainty is vital for attracting investors in renewables for genera- tion, transmission, and distribution • The implementation of the Kyoto Protocol combined with higher fuel prices is important in attracting PPPs in renewables, underscoring the value of legal commitments • Control for corruption and degree of political competition primarily affect investors’ decisions to enter the various power sector markets, not the subse- quent level of investment—indicating that investors seem to be adequately protected against risks • Market size (as measured by population) matters more than the “affordability� level of consumers (as measured by income) for attracting PPPs in the power sector. A Profile of PPP Power Activities So what does the latest data tell us about PPP investment in the power sector— and here we will focus on the developing world. On a regional basis, the key summary statistics show that PPP investment is highly concentrated (figure 2.3). For generation from conventional sources, East Asia and the Pacific (EAP) leads, 38 A World Bank Study Figure 2.3  Most PPP Investment in the Power Sector Comes from … a.

How PPPs Are Faring Globally 39 closely followed by Latin America and the Caribbean (LAC) leads, and, with a significant gap, the South Asian Region (SAR) and Europe and Central Asia (ECA). For generation from renewable, LAC leads, closely followed by EAP, and with a gap, ECA. In the Middle East and North Africa (MNA) and Sub-Saharan Africa (SSA), little investment in generation has been recorded. In transmission and distribution, LAC leads, followed, but with a significant gap, by ECA and MNA. In the remaining regions, here, too, little investment has been recorded. Of the total PPP investment in electricity generation, fossil fuels account for the lion’s share—about 75 percent (figure 2.4). Coal accounts for 35 percent, natural gas 24 percent, and fuel oil 15 percent. Total investment in renewables represents a mere 4 percent, if hydropower, at 22 percent, is excluded. Within that group, wind and geothermal technologies have almost an equal share of about 40 percent, with waste limited to 20 percent. Although the current share of PPP investment in renewables among develop- ing countries is still quite small, the data show a dramatic rise in this type of investment—following the adoption of the Kyoto Protocol in 1997 and the introduction of support schemes (particularly feed-in tariffs) in Europe in the early 1990s. The East Asian and Russian crises in 1997/98, as well as the Latin American crisis in 2001, hurt PPP investments in renewables, but recent short- run shocks have taken less of a toll. Among the fossil fuels, there is some evidence of switching of PPP investment from oil and coal to natural gas (figure 2.5). Indeed, natural gas is the only fossil fuel that has substantially increased its share of PPP investment from about 10 percent in the early 1990s to above 50 percent in 2002, then decreasing to below 40 percent in 2008—although in dollar terms, 2008 was a peak, with investment reaching above US$12 billion. There is also some evidence of switching of PPP investment from fossil fuels to hydro and renewables. Figure 2.4  PPP Investment in Renewables is Still Small and Mostly in Wind and Geothermal a.

Not surprisingly, each region has attracted PPP investment based on its energy endowment and untapped potential (figure 2.6). • East Asia leads in attracting the most oil and coal (more than 40 percent), geothermal (more than 80 percent), waste (70 percent), and wind (just below 50 percent) • Latin America leads in attracting the most natural gas (35 percent) and renew- able, including hydropower (50 percent) Figure 2.6  Global PPP Investment in Various Energy Sources 1990–2008, US$ million         a.

Coal. PPP investment in coal-based generation reached its first peak of US$10 billion in 1997, then declined sharply after the East Asian crisis, but rose to a new peak of US$20 billion in 2007. EAP accounts for the largest share of cumu- lated private investment in coal (about 50 percent of the total investment in this fuel), followed by SAR and ECA. The other three regions account for very small percentages. Oil. PPP investment in oil-based generation declined sharply from the peak of US$6 billion in 1995 to US$100 million in 2004, but edged up again in recent years, reaching alm ost US$900 million in 2008, triggered by the emer- gency rental of diesel mobile plants to face power outages. EAP accounts for the largest share of total cumulated investment in oil, although the share has declined sharply from 80 percent in 1993 to 5 percent in 2005 and zero since 2006. LAC’s share has also declined sharply from almost 100 percent in 1992 to 40 percent in 2006 and then zero. However, two regions have been boost- ing their shares. SAR has increased its share from an insignificant percentage in the early 1990s to more than 70 percent in 1998, and is now about 50 percent. SSA is the region for which oil-based generation has increased the most, given its vulnerability to severe power outages, which require emer- gency intervention. Natural Gas. PPP investment in natural gas-based generation first peaked at above US$5 billion in 1997, then declined sharply after the East Asian crisis and stabilized at levels above US$4,000, only to shoot up to a new peak of US$12 billion in 2008. This recent investment boom was driven by ECA, which accounted for almost 90 percent of the total annual investment. LAC accounts for the largest share of total cumulated private investment in natural gas, although its annual share has declined sharply from 80 percent in 1993 to 40 percent in 2006 to 5 percent in 2008. EAP has the second largest share of total cumulated investment, but most of the new investment took place up to 2001 and has since declined sharply. Besides ECA, new investment is picking up in SAR, which accounts for about 15 percent of the cumulated investment and, since 2004, 45 percent of the annual investment. A similar rising trend is occur- ring in MENA, which accounts for about 10 percent of the cumulated invest- ment but, as of 2006, 40 percent of the annual investment. Hydropower. PPP investment in hydropower first peaked at slightly above US$4 billion in the mid-1990s and then again in 2003, before falling off and then shooting up to over US$10 billion in 2007. LAC is the big driver, with Brazil alone attracting more than 35 percent of the PPP hydropower How PPPs Are Faring Globally 43 investment in developing countries, followed by Chile and Argentina each with more than 5 percent of investment. The other big player is South Asia, with India accounting for more than 15 percent of investment and China about 10 percent. Specific risks for hydropower investment arise for project financing, such as hydrological uncertainty, construction cost overruns, schedule slippage, and power demand uncertainty. Geothermal. PPP investment in geothermal first peaked at US$720 million in 1994, then US$920 million in 1997 before falling down to a peak of US$400 million in 2006. EAP hosts some of the largest resources of geothermal energy in the world, with both Indonesia and the Philippines announcing intentions to become the world leader in geothermal production. Indonesia alone accounts for 40 percent of global geothermal potential, and it is leading with 40 percent of total investment, followed by the Philippines with 33 percent. In SSA, geo- thermal is a key resource for countries along the East African Rift Valley System, such as the Democratic Republic of Congo and Kenya. In Central America, El Salvador is the largest producer of geothermal energy, followed by Costa Rica and Guatemala. Investment in geothermal has significant upfront costs that must be spent prior to determining the viability of the resource basin. Key variables are (1) the short-term, up-front geological risk of exploration drilling and (2) the long-term geological risk of developing and producing a geothermal reservoir with a lower than estimated temperature, higher than estimated mineralization, or difficulty with injection of geothermal fluids back into the subsurface. Wind. PPP investment in wind reached US$240 million in 2001, then US$600 million in 2005 and then close to US$1.6 billion in 2008. China alone attracted more than 50 percent of PPP investment in wind. Not sur- prisingly, China is listed as the top country in the world in terms of wind power added capacity in 2009, ahead of the United States, Spain, Germany, and India and the second country after the United States in terms of existing capacity. Poland has been a fast mover, attracting 15 percent of the overall investment since 2005. Bulgaria follows, with more than 8 percent. It is also worth noting the effort by Turkey and India in attracting private investment in wind, which accounts for about 3 percent of the total PPP investment in each of the countries. The risk of lower revenue from a wind project owing to lower than expected wind speeds is a major factor affecting the finance terms and conditions of wind farms. For wind as for other grid-connected renewable-based energy, long lead times and an administrative process may be needed to ensure grid reinforce- ments or additional investment necessary in the distribution or transmission system. Regulations requiring the project developer to pay the grid cost only up to the nearest grid connection point (the so called “shallow� grid connection charges) minimize the risks for the project developers, but they increase the burden on the network operator. 44 A World Bank Study Waste. PPP investment in waste reached its high at about US$560 million in 1996, fell sharply after the Asian crisis, and is now close US$300 million. Thailand alone accounts for 50 percent of the total PPP waste investment in developing countries, with biomass by far the largest contributor to power gen- eration and the second largest source of renewable energy. Other countries notably active in this area are Brazil with more than 20 percent of the total PPP waste investment, and China with 12 percent. Municipal solid waste projects have been proposed but only infrequently implemented. Privately owned renewable energy projects that produce electricity under the Small Power Producer (SPP) and Very Small Power Producers have been pioneered in Thailand and Sri Lanka and, recently in SSA with Tanzania (box 2.1). Box 2.1 Small Power Producers and “Light Handed Regulation� Small Power Producer (SPP) regulations enable expansion of renewable generated electric- ity through model power purchase agreements, standardized tariffs, and streamlined interconnection and licensing requirements. The regulations provide the legal basis for customers to self-supply with small clean renewable energy or cogeneration generators and to export excess power (up to 10 megawatts) to the national utility (either the national grid or mini-grids). But SPPs will only develop if the prices that they receive for their electrical output exceed their own costs of production. For example, where main grid connected SPPs can sell at an administratively set price of about US$10 per kilowatt-hour, the only SPPs that are commer- cially viable are cogenerators, some biomass generators, and some mini-hydro generators with well-endowed sites. Solar and wind generators are generally not viable at this price level. In Tanzania, SPPs will occasionally replace some or all of the production of existing diesel generation of mini-grids operated by TANESCO (the national government-owned utility). In other cases, it will bring electricity to communities without electricity. EWURA, the Tanzanian electricity regulator, has made a conscious effort to employ “light handed regulation� in its regulation of SPPs. This means (1) minimizing the amount of information that is required, (2) minimizing the number of different regulatory requirements and decisions, and (3) relying to the extent possible on related reviews by other Tanzanian government entities. Both Thailand and Sri Lanka, with similar SPP regulations, have encountered problems in which companies apply for PPAs with the intention of selling these PPAs at a profit. In Thailand, one company accounts for 445 megawatts of signed PPAs for grid-connected solar photovoltaic (PV), but none of these projects have been built. In Sri Lanka, companies have tied up key micro-hydro sites with PPAs that have failed to develop into projects even after a number of years. To discourage this form of “PPA speculation,� EWURA’s license approvals “expire� after two years, giving other developers the chance to move in and develop the site.

How PPPs Are Faring Globally 45 As for transmission and distribution, the past financial crises—notably the East Asian and Russian crisis in 1997/98 as well as the Latin American crisis in 2001—have hurt PPP investment (figure 2.7). In distribution, most of the privatizations in Latin America took place in the 1990s, with investment peaking at about US$14 billion in 1997 (accounting for about 80 percent of the total global PPP investment in distribution that year). Eastern Europe and Central Asia followed with investment peaking at about US$1.4 billion in 2005 (accounting for about 80 percent of the total global PPP investment in distribution that year). In transmission, most LAC private sector participation took place in the sec- ond half of 2000, with a peak of about US$2.5 billion in 2006 (accounting for more than 95 percent of the total global PPP investment in transmission that year). In SAR, which came in second, investment peaked at about US$700 million in 2007 (accounting for about 80 percent of the total global PPP invest- ment in transmission that year). In ECA, a few countries, including Romania and Georgia, have attracted private investment with considerable success. Transelectrica SA, the Romanian transmission operator, was the first state- owned company listed on the Bucharest Stock Exchange in 2006, recording significant improvement in technical and financial performance (box 2.2). In Georgia, the Irish company ESBI was awarded a five-year management contract to improve performance of the Georgian State Electrosystem, the Georgian state owned transmission operator, in 2003. The contract represents one of the few cases—and a successful one—of the use of management contracts in trans- mission (box 2.3).

This followed the company’s successful 2001 restructuring. Although the num- ber of employees stayed about the same, labor productivity (measured as revenues per employee) rose sharply from before the restructuring, reaching peak levels in 2006 and the following years. On the financial side, the company experienced losses in 2002/03 but then turned profitable and remained so—hitting a high the year of the listing—although profits fell off in 2009 following the financial crisis. In terms of transmission losses and failure, the company already had a low level before the public listing, thanks to the restructuring, and further improvement occurred after the listing.

How PPPs Are Faring Globally 47 Box 2.3 A Management Contract for the Georgian State Electrosystem In 2003, Georgia gave the Irish company ESBI a five-year management contract to overhaul the Georgian State Electrosystem, which had been experiencing major financial and opera- tional problems. The result was a dramatic improvement in the the state-owned transmission operator’s performance. On the financial side, the number of employees was reduced sharply from 4,500 employ- ees in 2002 to 1,048 in 2007 (the last year of the contract), enabling an almost threefold rise in labor productivity. Profitability also increased, as the cash collection rate jumped from 36 percent in 2003 to about 100 percent in 2007. In fact, the utility managed to post a profit in 2005, after reporting losses for a number of years before, and remained profitable (although there was a significant 2006 dip) until 2009, after the contract’s end.

(box continues on next page) 48 A World Bank Study Box 2.3  A Management Contract for the Georgian State Electrosystem (continued)    Another challenge faced by the ESBI management team was a high level of transmission losses, which had reached 16 percent of the purchased electricity by 2003. But by 2006, these were lowered to about 2 percent—a level comparable to West European transmission sys- tems losses—and have stayed there. The high level of blackouts was also ended, falling from 11 in 2002 to zero in 2006, and staying there. The number of partial blackouts also dropped significantly, from 24 in 2003 to under 5 by 2007, and they have remained low. The Role of Sectoral Governance What has been the biggest hurdle for developing countries in attracting invest- ment in renewable? The prevailing belief in policy circles and the literature is that sectoral governance issues matter greatly—notably, support mechanisms and regulation. The Role of Renewable Support Mechanisms in Generation Renewable energy support and incentive mechanisms are the key factors driving the growth of a market in renewables. Current policies that support renewable energy use either price—the most popular one—or quantity setting instruments, although they can be used together. Price-based systems. The main price-based system is feed-in tariffs, which obligate electric utilities to purchase renewable energy through long-term con- tracts that guarantee access to the grid at a guaranteed price or an addition to the prevailing market price. They are attractive because a stable revenue stream across a pre-established timeframe reduces risk around cash-flow. Indeed, an IEA analysis indicates that the cost of capital will be higher in support schemes with traded obligations given the lack of certainty over the revenue stream.1 These tariffs can be applied consistently and transparently and can be readily adapted to different specific power market structures—such as being offered as a premium on top of the spot-market electricity price (Cory et al. 2009; Couture et al. 2010). And they have a clear track record of delivering significant volume increases in its deployment. Of the different options available to attract private investment in renewable energy, feed-in tariffs are increasingly seen as the “policy of choice�(Burer and Wustenhagen 2009; DB Climate Change Advisors 2010; Lesser and Su 2008; Lipp 2007; Menanteau et al. 2003; Mitchell et al. 2006; REN 21 2011). They are used in a majority of European countries, where their effectiveness has been well documented. A study comparing the effect of feed-in tariffs to other policy mechanisms designed to support the spread of wind energy found that they resulted in 7–8 times as much installed wind capacity. (European Commission, as reported by Thomas B. Johansson, Chair, Global Energy Assessment). Indeed, How PPPs Are Faring Globally 49 the overall success of the German, Spanish, Danish, and other national level feed-in programs has inspired similar initiatives in developing countries, includ- ing China and, more recently, South Africa and India, as well as regional and state governments in the United Kingdom, United States, and Australia. Globally, feed-in tariffs are current used in about 80 states and countries, more than half of which are developing economies (figure 2.8). The most important element of feed-in tariffs is that they fully or partially remove the market risks of a project during a fixed period of time. The lon- ger this period of guaranteed prices, the lower the cost of capital. Because of this, they are generally financed with a relatively large proportion of debt. In feed-in premium schemes, the risk of variations in electricity market prices is reflected by the tariff premium in the purchase power agreement (PPA). But private investors may struggle to acquire a PPA with a 15–20-year tenor at reasonable risk premium levels, which is why a strong government com- mitment toward the scheme is essential. Changes in the scheme—such as increasing the economic lifetime, the contract period in the PPA, and the debt maturity—will reduce debt service costs, but they must be done care- fully to avoid seriously affecting the continuity of existing projects. This could be achieved by setting favorable conditions in loan guarantees, (low- interest) government loans, and government participation. The government can also force parties to offer long-term contracts. A major challenge with this price-based instrument is striking the right level of feed-in tariff. A low feed-in tariff may not trigger enough investment in renewable-based energy, but a high feed-in tariff may inhibit cost reductions. Figure 2.8  Feed-in Tariffs Are Being Increasingly Adopted Worldwide 90 Cumulative states and countries adopting feed-in tari s 80 70 60 50 States 40 30 20 10 0 78 90 91 92 93 94 02 03 97 98 99 00 01 04 05 06 07 08 09 10 19 19 19 19 19 19 19 19 20 20 19 20 20 20 20 20 20 20 20 20 Year Emerging and developing Advanced Source: REN21 2011. 50 A World Bank Study This illustrates the importance of designing an efficient energy support system, which not only promotes diffusion but also provides continuous incentives for cost-reducing innovations. The rapid expansion of the Spanish solar PV and subsequent intervention to contract the market in 2008 (capping overall market size, alongside a 30 percent cut in the tariff) has been attributed as much to tariff design as to setting the tariffs at unsustainably high levels. In contrast, Germany prescribed stepped tariff reductions (degressions) and has produced steadier growth. Quantity-based systems. A major alternative to feed-in tariffs is the system of tradable certificates or the quota obligation framework. The most popular type are renewable portfolio standards, which require utilities to supply a cer- tain percentage from renewable energy by a given year and leave it to the market to determine the price. They are widely used in the United States, especially in developing extensive wind resources, but only a few European and developing countries have used them (box 2.4). One problem with quotas systems is that it is more difficult to lower risk premiums in the cost of capital than with feed-in tariffs. Another problem, which has been pointed out in the U.S. experience, is that they may be less effective for incentivizing nascent, higher-cost technologies or a stable invest- ment environment for renewables. Even though feed-in tariff schemes and renewable portfolio standards approaches are presented as alternatives (Mitchell et al. 2006; Rickerson and Grace 2007), these policies can also be used together with renewable portfolio standards prescribing how much customer demand must be met with renew- able-based energy and feed-in tariff policies setting the right price and providing investor certainty (Cory et al. 2009). The Role of Regulatory Governance in Transmission and Distribution The main aim of electricity regulation is to provide utilities with incentives to improve their operating and investment efficiency and to ensure that consum- ers benefit from the gains. Electricity distribution networks are highly capital intensive systems and timely investments to maintain and upgrade the assets are crucial for long-term reliability and expansion of their service, as well as to cope with integrating renewables. The regulators are in a position to decide what is a reasonable level of capital expenditure, a reasonable level of operat- ing expenditure, and the allowed rate of return on regulated assets. These three elements represent around one-third each of the total regulated revenue for distribution. In recent years, in the hopes of attracting significantly higher private invest- ment or private finance within the public sector, major regulatory reforms have taken place in the developing world. Some efforts, such as in India and China, have been aimed at creating an effective regulatory framework. Other efforts have involved promoting independent regulatory agencies in electricity. In fact, since 1995, there has been an exponential growth in the number of autonomous How PPPs Are Faring Globally 51 Box 2.4 Poland Uses Quota Systems for Renewable Generation A major alternative to feed-in tariffs is the system of tradable certificates or the quota obliga- tion framework, which is a quantity based system. It has been adopted by Latvia, Poland, and Romania, and the Czech Republic (which also uses the feed-in tariff). In 2000, the Polish government introduced a power purchase obligation for renewable energy sources, which was first amended in 2003, and again in August 2008. It requires energy suppliers to provide a certain minimum share of power generated by renewable sources (from 3.1 percent in 2005 up to 10.4 percent in 2010 and 12.9 percent in 2017). The electricity from renewable energy sources is purchased at a guaranteed price which is the median electricity price for the previous year. In 2010 this stood at 197.21 Polish Zloty (PLN) per megawatt-hour. If a company does not fulfill its obligation according to the quota regulation, a penalty will apply that is equal to 248.46 PLN per megawatt-hour and an additional 30 percent fine cumulates to the initial fee if it is not duly paid. But the European Commission’s 2007 report found that fines were not enforced. In 2005, the Polish Law on Energy (1997) was amended to obligate all renewable energy producers, regardless of the size of the instal- lations, to obtain a license from the Energy Regulation Authority. Following this new requirement, more than 600 producers of renewable energy applied for and received licenses for producing electricity from renewable sources. Since then, cumulative power installation in renewable energy has shot up from about 1,227 megawatts in 2005 to close to about 2,282 in 2010 (see table B2.4 on next page)—with wind generation taking the lead at about 1,000 megawatts in 2010 (see figure B2.4 below).

However, despite progress in economic regulation of networks in recent years, devising suitable incentives for network investments still remains a work in progress and a challenge for many regulators (see Joskow 2008; OFGEM 2010). On the positive side, the introduction of regulation, particularly incentive regulation regimes based on price cap regulation (RPI-X). models and bench- marking, has typically improved the efficiency of network utilities.2 In addition, there is now more systematic evidence that better regulatory governance increases efficiency. Many recent studies—which include countries in Latin American, Asia, and Africa—show that having a regulatory agency helps (either directly or indirectly) boost mainline capacity per capita and labor productivity (such as Figure 2.9  A Rising Number of Autonomous Regulators in Developing Countries 60 50 40 Number 30 20 10 0 93 94 95 96 97 98 99 00 01 02 03 04 05 06 07 08 19 19 19 19 19 19 19 20 20 20 20 20 20 20 20 20 Year Source: World Bank data elaboration. How PPPs Are Faring Globally 53 Cubbin and Stern 2006). Moreover, Andres et al. (2008) suggest that the mere existence of a regulatory agency, regardless of the utilities’ ownership, significantly improves performance. Going forward, substantial new investment in transmission and distribution networks may be needed to handle the introduction of large amounts of (both large and small scale) renewables and gas-fired microgeneration into the elec- tricity system. Elders et al. (2006) identify the following technologies as being potentially important to do this: new power electronics, flexible alternating current (AC) transmission system, storage facilities, and superconducting lines. Future networks will necessitate more active management, given the intermit- tency of renewable energy. And the uncertainty of the timing, volume, and location of new renewables will make planning network development more difficult than before, which will also complicate regulation. How the Econometric Study Was Done Against this background, our study aims to identify the key factors affecting the private investor’s decision to enter the market of generation, transmission, and distribution and the amount of investment sunk in each market segment. To do this, we undertook an econometric study of 105 developing countries, covering all the regions, from 1993 to 2008 (see appendix C for detailed methodology) We divided the determinants of PPPs that are used as explanatory variables in our model into three channels (1) sectoral and economy-wide governance, (2) long-run environmental sustainability factors, and (3) short-run financial crises and economic fundamentals (see appendix C’s table C.1 for dependent variables and table C.2 for explanatory variables). In these three areas, we asked the following questions: Sectoral and Economy-wide Governance • To what extent have support mechanisms, including feed-in tariffs, been effective in attracting private investment in renewables and encouraging some degree of switching between investment in fossil fuels and renewable-based generation? • To what extent has higher regulatory governance been effective in attracting private investors to provide investment in transmission and distribution? • To what extent have broader governance variables—such as control for cor- ruption and more political competition—made a difference, vis-à-vis sectoral mechanisms in attracting private investment in each of market segments? Long-run Environmental Sustainability Drivers • To what extent did higher oil prices encourage a degree of switching between investment in fossil fuel and renewable-based electricity generation? • To what extent have developing countries been able to attract and retain PPP investment, particularly in renewable energy, in the years following the 54 A World Bank Study entry into force of the Kyoto Protocol, as climate change moved up the political agenda? • To what extent have countries that prepared to integrate renewables in their systems by enhancing investment in the transmission grid, attracted higher investment in renewable-based generation? Short-run Crises and Economic Fundamentals • Did countries facing severe financial crises encounter problems attracting new PPPs in the power sector and then keeping that level of PPP investment after the crisis? • What has been the influence of higher income and the size of the market on attracting PPPs and a higher volume of PPP investment? The micro, project-level data come from the Private Participation in Infrastructure (PPI)3 database, which is managed by the World Bank and the Private-Public Infrastructure Advisory Facility (PPIAF). The information for each project recorded in the database is (1) country and region4; (2) year of financial closure and total life period of the project; (3) total investment (in both monetary value and physical capacity); and (4) sector, subsector, segment, and technology (fuel) of each project.5 The macro data are collected from other central databases, including (1) the World Development Indicators (WDI) 2009 and the World Governance Indicators and Polity IV; (2) the IEA’s Energy Balances and Statistics 2009; and (3) the U.S. Energy Information Agency. Econometric Results Our study shows that overall PPPs weigh governance, economic fundamentals, and climate change before even entering the power sector. As for the level of investment, however, governance is not a factor but economic fundamentals and climate change are (tables 2.1 and 2.2). The breakdown by generation, transmis- sion, and distribution follows. More technical details of the econometric results are provided by Vagliasindi (2012a, 2012b, 2012c). Generation The results show some evidence of switching from investment in fossil fuels to investment in hydro and renewables and within fossil fuels from oil to natural gas. Such a switching decreased PPP investment in oil-based power generation. They also show the crucial importance of support schemes to attract private investment in generation (including both conventional and renewable sources). The key results are: • Sectoral governance support schemes—such as feed-in tariffs—are crucial for encouraging investment in renewable-based generation. However, they do How PPPs Are Faring Globally 55 Table 2.1  Before Entering the Power Market, PPPs Weigh Governance, Economic Fundamentals, and Climate Change key determinants of introduction of PPP investment in power sector GEN REN T&D T D Sectoral governance variables Introduction of feed-in tariffs +** +** — — — Electricity regulation — — +*** +** +* Economy-wide governance variables Control of corruption +*** +** — — — Degree of democracy +** +* — +** +** Long-run economic fundamentals GDP +*** — +*** +*** +*** Population +*** +*** +*** +*** +*** Long-run environmental sustainability factors PPP investment in transmission +** ++** — — — PPP investment in renewables — — +*** +*** +***   Price of oil –** — — — — Price of oil*Kyoto protocol +** +* — — — Note: *, **, *** indicate significance of the coefficient, respectively, at 10 percent, 5 percent, and 1 percent confidence level; — = variables not included in the regression.

This suggests that the first generations of independent power producers responded to quite favor- able and long-term power purchase agreements, which shifted most of the risks to the public sector. These mechanisms were demanded by the investors to offset reform difficulties. For example, postponing tariff adjustments and delay- ing unbundling efforts to separate transmission from generation reduced the creditworthiness of power purchasers • Oil price increases (which correlate highly with other fossil fuel prices) drive investments in renewables up and those in fossil fuels down. But because the reduction in fossil fuels is larger than the increase in renewables, the overall impact of a higher oil price on investment in generation is negative • However, the introduction of the Kyoto protocol combined with higher fossil fuel prices enhances the probability of investing in renewables, thereby boost- ing overall PPP investment in generation. This result shows the importance of legal international commitments to further generate confidence and foster investment • Private investors entering the market look more at market size than income level (the “affordability� level of consumers), but they look at both when deter- mining how much to invest in generation. This result raises concerns about the sustainability of such support mechanisms for renewables and their financing, particularly when the incremental costs implied by renewable-based generation are passed through to consumers. Renewable-based Generation Here, too, the results show strong evidence of the effectiveness of support mechanisms. The key results are: • The renewable energy market is strongly driven by supportive policies, which not only attract the entry of private investors but also determine the level of investment. However, the influence of these policies over how much is invested could be much greater than it is suggesting the need to ensure that they are powerful enough and that they adequately allocate risks between the public and private sectors • However, economy-wide governance factors (control for corruption and degree of political competition) are considered by private investors mainly for taking the decision to enter into renewable-based generation, not what happens later. This finding reinforces our belief that private investors seem to be adequately protected against risks, so that once they enter the market, they can accommodate the governance environment • Private investors also require technical and regulatory certainty about the availability of renewable-ready transmission resources. The traditional reactive model of transmission regulation, where transmission is developed on a first-come, first-served basis is not conducive for renewables, as it introduces How PPPs Are Faring Globally 57 extensive regulatory and technical uncertainty about whether adequate trans- mission will be available once the resource is generated—and transmission distances for renewables can be large • Private investors entering the market look more at market size than income level, whereas when determining the level of investment they assess both. This finding parallels that found for overall generation and thus here, too, raises concerns about the sustainability of support mechanisms and their financing, particularly when the incremental costs implied by renewables are passed through to consumers. In sum, private investors will assess the policy and regulatory regimes across all aspects of the project, not just the support or incentive mechanism. These aspects include the planning and approval process, given the potential for costly delays to construction that defer the point at which a project will start generating revenue; grid or infrastructure access and availability; and power purchase agreements. Transmission and Distribution The results show that regulatory governance is important in attracting and maintaining private investment in transmission and distribution (T&D). The key results are: • Sectoral regulatory governance is crucial in attracting the entry of private investors in T&D, but it does not affect the level of investment. This result suggests that, before entering the market, private investors value regulatory certainty. After entry, as the tariff formula is usually guaranteed in the medium term in their contracts, the presence of an autonomous regulator does not affect the level of investment. Another reason may be that implementation is less than optimal. Furthermore, as mentioned above for renewable-based generation, the traditional reactive model of transmission regulation, is not conducive to renewables • Similarly, economy-wide governance factors, including control for corrup- tion and degree of political competition are factored in by private investors only in the initial stage of the game when the decision to enter into the T&D market is taken. This finding again reinforces our suggestion that pri- vate investors seem to be adequately protected against their risks, so that once they have entered the market, they can accommodate the governance environment • The introduction of renewables in the power system enhanced overall PPP investment in T&D. Renewable-based energy also requires technical and regu- latory certainty about the availability of renewable-ready transmission resources • Private investors entering the T&D market look more at market size than income level, whereas when determining the level of investment in T&D they assess both the size and “affordability� level of consumers. This finding parallels those for generation and renewable-based generation. 58 A World Bank Study The bottom line is that sectoral governance—that is, support mechanisms, such as feed-in tariffs, and regulations—play a critical role in attracting private invest- ment in generation, transmission, and distribution. Which incentive schemes work better than others in attracting PPP investment in renewables? The next chapter reviews case studies we did on China, Brazil, Mexico, and Peru to explore that question, along with the challenges of the transmission grid to integrate private investors into the system. Notes 1. IEA analysis indicates that a 2–30 percent cut in the cost of renewable energy can result from improved design of incentive or support schemes, with the higher end of this range linked to projects with higher project risk, such as offshore wind. 2. The recent literature on regulatory governance for utility service industries has been pioneered by Levy and Spiller (1994). 3. http://www.ppiaf.org/ppiaf/page/private-participation-infrastructure-database 4.

CHAPTER 3 Renewable Energy Case Studies Renewable energy support and incentive mechanisms are the most important factors driving the growth of a market in renewable-based energy—and they can come in many forms: • Price-based support. The most popular is a feed-in tariff (FIT), favored by a majority of European countries (such as Germany and Spain) and widely used in developing countries. This system sets a guaranteed price for renewable energy generation or an addition to the prevailing market price • Quota-based support. The most common is a Renewable Portfolio Standard (RPS), favored by the United States, Canada, and India. It typically requires power utilities to use a given proportion of electricity from renewables, and it is often combined with mandates for utilities to meet obligations through trad- ing Renewable Energy Certificates (also called Tradable Green Certificates) • Fiscal incentives. These typically include tax breaks and capital subsidies • Financial supports. These typically involve public investment, loans, or financing. What is the emerging experience with these mechanisms to date? Typically, feed- in tariffs—despite offering simplicity—tend to be set on the high side, because they induce generators to choose high-cost sites and provide fewer incentives than other mechanisms for cost cuts. This problem illustrates the importance of designing an efficient energy support system, which not only promotes diffusion but also provides continuous incentives for cost-reducing innovations. In con- trast, competitive auctions have tended to be low initially and are not always the most-effective instrument for renewables, but they allow for a discovery effect to determine the market-based feed-in tariff to attract private investment. How do these mechanisms influence public-private partnerships (PPPs) in the power sector in the developing world? And what role should PPPs play in efficiently expanding a transmission network system with natural monopoly characteristics and thus subject to public regulation? To answer these questions we undertook a study of four country cases that present a wide range of schemes aimed at promoting renewable energies, different ownership (fully private or public or a mix) and market structures, and different levels of renewable energy 61   62 A World Bank Study Table 3.1  Case Study Taxonomy Incentives/mechanisms to promote renewable Renewable energy Ownership Market structure energies penetration China Mainly state-owned.

For example, in terms of incentives, China has moved from auctioning to feed-in tariffs, Mexico has done the reverse, and Brazil and Peru are using competitive auctions. The Case of China Electricity Market Reforms In 2002, the Chinese government dismantled the monopoly State Power Corporation (SPC) into separate generation, transmission, and service units (U.S. Energy Information Administration). Since then, China’s electricity generation sector has been dominated by five state-owned holding companies: China Huaneng Group, China Datang Group, China Huandian, Guodian Power, and China Power Investment. The remaining generators are independent producers, which often partner with privately listed arms of state-owned companies. Renewable Energy Case Studies 63 While the generation sector has some market competition, the transmission and distribution sectors are heavily state-owned and controlled. During the 2002 reforms, SPC divested all of its electricity transmission and distribution assets into two new companies, the Southern company and the State Power Grid Company. The government also established a national power regulator, the State Electricity Commission (SERC). Generation In 2009 China had an estimated total installed electricity generating capacity of 874 gigawatts—74.6 percent of which came from conventional thermal sources, mostly coal (figure 3.1). That capacity is expected to grow a lot in the next decade to meet rising demand, particularly from demand centers in the eastern and southern parts of the country. China’s goal is to generate at least 15 percent of total energy output with renewable energy sources by 2020, as the government shifts to a less-resource intense economy—a goal it has already met with renewables now accounting for 17 percent (table 3.2). In 2009, China became the second largest producer of Figure 3.1  Fossil Fuels Dominate Production and Capacity a. Coal, Oil & Gas, Nuclear, Hydro, and Wind b.

Installed hydroelectric gener- ating capacity was around 197 gigawatts in 2009, accounting for over 20 percent of total installed capacity. Wind is the second leading renewable source of power generation, with 0.7 percent, and biomass is third with 0.6 percent (table 3.2). However, despite significant efforts to diversify its energy mix, China’s depen- dence on coal and fixed electricity tariffs have provoked major outages. Although coal prices have more than doubled in the past decade, electricity tariffs have only increased by a third. Making matters worse has been an unusu- ally severe drought. Transmission Investment shortages in electricity transmission and distribution have become the bottleneck of power development in China. During the 8th, 9th, and 10th Five-Year-Plans the shares of investments in transmission and distribution were 13.7 percent, 37.3 percent, and 30 percent—significantly below the 50 percent average of developed countries. Nevertheless, investment levels have been grow- ing consistently. In 2006, total investment in power grids construction was 210.6 billion renmibi (RMB), up 38 percent from 2005; in 2007, it reached 245.1 billon RMB, up another 16.4 percent. That same year, the national average line loss rate was 6.97 percent, down 0.07 percent from 2006 (In-depth Investment Report on Power Grid Industry of China, 2009). Renewable Energy Reforms Renewable energy planning in China took place through two phases (REN21 2011): • Phase One (1996–2000): Use research and development and demonstration projects to elevate most renewable energy technologies to a level near or equal to advanced international standards. Commercialize some of the mature tech- nologies, extend their application, and develop markets gradually. Improve on traditional, low-efficiency biomass energy consumption by making wider use of wind, solar, and hydro energy to help electrify remote areas and islands • Phase Two (2000–10): Disseminate renewable energy technology on a wider scale; create advanced, international standard industrial and technology research systems; achieve large-scale production; and increase the total development and use of all new and renewable energy sources from 300 million tonne of coal equivalent (tce) at present to 390 million tce. Of all the measures taken, it was the implementation of the 2005 Renewable Energy Law on January 1, 2006 that gave an unprecedented impulse to renew- able energies. The renewable energy sector boomed, resulting in China taking a leading position globally, particularly in wind power, solar water heating, and small hydropower. The law provides four schemes (1) a cost-sharing scheme Renewable Energy Case Studies 65 that requires that additional costs of renewable energy generation are shared by electricity end-users through a surcharge, (2) a feed-in tariff scheme, (3) a man- datory grid-connection system that requires grid operators to buy all electricity generated from renewable sources, and (4) a national target system that sets strategic objectives to achieve 10 percent of renewables in primary energy use by 2010 and 15 percent by 2020 (Renewable Energy Policy Network for the 21st Century 2009). Another landmark for renewables was the Medium and Long Term Development Plan for Renewable Energy 2007. It outlined a Renewable Portfolio Standard (RPS) target, stating that in areas covered by large-scale power grids, the non-hydro renewables share of total generation will reach 1 percent by 2010 and exceed 3 percent by 2020. The government also estab- lished the Renewable Energy Fund to cover the gap between the cost of the feed-in tariffs paid to generators and the prices paid by consumers as well as the additional capital costs of transmission extensions. The 2009 Renewable Energy Law amendments expanded the uses to include subsidizing the grid companies for the costs of integrating renewable energy that they cannot recover from electricity sales to consumers. The big push for wind power came when the National Development and Reform Commission (NDRC) initiated the wind power concession program to introduce competition, relying on bid based off-take prices. In 2003, it launched the first concession tender, mandating turbine local content to promote the country’s wind industry. From 2003 to 2008, five concession tenders were orga- nized, first mandating 50 percent local content, then 70 percent. However this requirement was later removed because it was construed as a breach of World Trade Organization rules. The electricity off-take price was theoretically deter- mined by the winning bid price up to 30,000 hours of full load operation and at the average network electricity price for generation exceeding that amount. The contract is for 25 years. The lowest bid (later changed to the closest price to the average of the bidding price with the highest proportion of local content) is awarded the concession projects. Since 2005, and despite the global financial crisis, China’s installed wind capacity has increased to about 45 gigawatts in 2010 from 1.3 gigawatts in 2005 (figure 3.2). In fact, in 2009, the wind power industry was among the few new industries to stimulate the world economy toward recovery—with global invest- ment exceeding US$60 billion, of which China alone accounted for over US$20 billion (China Wind Power Outlook 2010). Globally, newly installed capacity of global wind power rose by 42 percent, and in China, by 166 percent over the 2008/09 period. Analysts predict that China’s base of wind power installations will total 50–60 gigawatts by 2015 and 80–100 gigawatts by 2020. The 2020 goal was revised upward fourfold from the 30 gigawatts goal set by the Mid to Long- Term Development Plan for Renewable Energy, promulgated by Beijing in September 2007. Moreover, experts and government officials predict that 66 A World Bank Study Figure 3.2  China’s Installed Wind Power Capacity Has Skyrocketed 50 45 40 35 Gigawatt 30 25 20 RE energy law 15 10 5 0 00 01 02 03 04 05 06 07 08 09 10 20 20 20 20 20 20 20 20 20 20 20 Year Newly installed capacity (GW) Cumulative installed capacity (GW) Source: Junfeng et al. 2010; REN21 2011. domestic installed wind-power capacity may reach as high as 100–150 gigawatts by 2020 (Renewable Energy Policy Network 2009). Incentives to Promote Renewable Energy Under the 2005 Renewable Energy Law, China has implemented a number of pricing mechanisms and cost arrangements. There are different pricing schemes for different technologies—and pricing arrangements for wind and solar have changed over time as these technologies developed. Cost-plus. This approach—currently used for geothermal, and tidal power— involves setting a price for a particular project on the principle of reasonable production cost plus reasonable profit. It presents significant uncertainty for project developers, but is favored by the central government to stimulate nascent technologies (Tawney et al. 2011). Concessions. This is basically a competitive tender model, asking project developers to compete for long-term power purchase agreements, with price and domestic content as the key criteria. The NDRC held five bidding rounds between 2003 and 2007 for 3.35 gigawatts of onshore wind capacity and some provinces followed suit. The concession approach is still used for offshore wind, but it has led to downward price pressure and unprofitable onshore wind generation, deterring further private capital investment. The state-owned gen- eration companies were able to support their losses in wind through indirect state budget support and thus dominate the existing wind installed base (Tawney et al. 2011). Feed-in tariff. With this approach, the NDRC sets the rates that all genera- tors can charge the grid companies for the electricity they provide to the grid. The interesting feature of the Chinese system is that originally the prices estab- lished from the competitive bidding were used to set feed-in tariff rates. In other countries the levels of feed-in tariffs are usually set based on market analysis, surveys, industry research, and consultations with the public. In China, where Renewable Energy Case Studies 67 the renewable energy sector undergoes rapid changes—costs decrease quickly owing to technology improvements, increased efficiencies, and economies of scale—it would have been quite difficult to administratively set a fixed price without information from the bidding process. For wind power, in 2009 the government set nationwide guidance on the tariff—replacing the project-by-project cost-plus and the concession models, with guarantees for 20 years. Regions with poorer wind resources are paid a higher tariff to ensure profitability despite their lower productivity. Ranging from 0.51 Yuan per kilowatt-hour to 0.61 Yuan per kilowatt-hour (US$0.075 per kilowatt-hour to US$0.090 per kilowatt-hour), the rates are significantly higher than the average 0.34 Yuan per kilowatt-hour (US$0.05 per kilowatt- hour) paid to coal-fired generators. The rates are also significantly higher than the concession tariffs had been. (Tawney et al. 2011). For solar PV power, prior to 2009, when the market was small, the approved feed-in tariff rate was applied on an individual project basis and ranged between RMB4-9 (US$0.58–1.32) per kilowatt-hour. Since early 2009, the government has established price regulation with a concession program in Western China’s Dunhuang region. In August 2011 the NDRC announced the first national level feed-in tariff program for solar power. A feed-in tariff for the projects approved before July 1, 2011 or completed by December 31, 2011 is RMB 1.15 (US cent 17.9) per kilowatt-hour, excluding solar thermal. The tariff for the projects approved after July 1, 2011 and not completed by December 31, 2011 is RMB 1.00 per kilowatt-hour (US cent 15.5) (Bloomberg News 2011). For biomass power, a feed-in tariff is provided for all projects. In 2008, the subsidy of RMB 0.25 (US cent 3.7) per kilowatt-hour for a 15 year period was increased to RMB0.35 (US cent 5.1) per kilowatt-hour. Challenges Feed-in tariffs design. China’s feed-in tariff system has been criticized for being too complex and difficult to understand, especially for international investors. Some have suggested establishing a fixed-price structure for each technology based on its specific characteristics such as resource potential and geographical distribution (Renewable Energy Policy Network 2009). Development of the transmission grid. The rapid development of renewable energies in China (especially wind power) has put unprecedented strain on the country’s electricity grid infrastructure. In the past four years, China has dou- bled its wind turbine installations—accounting for more than half of the world wind energy market. However, the country has built turbines so quickly that it failed to keep up with construction and most turbines have not been connected to the energy grid. To smooth out the load variability, grid companies realize that it is impera- tive to take two interrelated measures (1) overcome the geographic mismatch of demand and supply by building additional power transmission lines to han- dle the transmission of larger quantities of electricity and (2) strengthen the 68 A World Bank Study interconnections between regional grids (Cheung 2011). In March 2010, Premier Wen Jiabao announced a plan to build a “unified strong and smart grid� system nationwide by 2020, which should incorporate energy supplies from various sources. Transmission costs. Renewable energy generators are not required to pay for the transmission infrastructure necessary to carry their power to load cen- ters. Grid companies pay for the transmission expansion directly and are required to connect any renewable energy generation within their geographic region that meets minimum requirements. Grid companies are partially reimbursed through a government subsidy based on the distance between the generation site and the main grid infrastructure (Tawney et al. 2011). However, the rates they can charge consumers are set as a part of China’s larger eco- nomic policy, and there is no guaranteed rate of return to the grid companies (Tawney et al. 2011). In China, the cost sharing model has not ensured that expansion keeps pace with the growth of renewables. The cost structure is very advantageous to renewable energy developers, but under the feed-in tariff model they indirectly pay the price for the lack of transmission investment when they cannot sell their electricity into the grid (Tawney et al. 2011). The Case of Brazil Electricity Market Reforms The first phase of reforms took place between 1996 and 2001, when the largest state-owned enterprise (ELETROBRAS) was unbundled into six holding corpo- rations and 14 generation and transmission companies. By 2001 more than 80 percent of the electricity sold in the country was conducted by privatized distributing companies (Jannuzzi 2004). However, generation remained domi- nated by state owned companies, with a 70 percent share, and transmission was left in state hands. In addition, the government established a number of new institutions, such as the National Electricity Regulatory Agency (ANEEL). The second phase of reforms began in 2003, right after Brazil’s worst energy crisis, which largely stemmed from several years of drier than average weather. The government of Inacio Lula Da Silva introduced a second “wave� of power market reforms (“new model�) to improve incentives for installing new genera- tion capacity, create more competitive conditions, and improve the institutional framework. The main characteristics of this new model were: • Less emphasis on the short-term “spot� market as a provider of signals for sys- tem expansion and more emphasis on the forward contract market to induce additions of new generation capacity • A requirement for mandatory energy auctions for distributions companies to cover 100 percent of all loads. Distributors could acquire energy only through contract auctions for long-term contracts (3–5 years) to reduce Renewable Energy Case Studies 69 risks for generation investors and promote competition. Benchmark prices were used for pass-through of wholesale power costs to consumers pro- cured under the new energy auctions, as supply costs reflect the average price of all contracts. The two models differed greatly. The original reform model (implemented in 1995) focused on opening up the power market with an emphasis on privatizing all companies. System expansion was supposed to be achieved through short-term price signals and contracting obligations. The new model (implemented in 2004), however, emphasizes coexistence between state-owned and private companies. Impact of Auctions on Electricity Transmission The introduction of auctions—the first was held in December 2004, with contracts for a total of about 40 gigawatts traded—significantly affected the transmission sector, whose expansion has since been driven largely by private investors. Public firms also participate in auctions, sometimes as individual firms, but more often joining a private consortium with less than 50 percent of its capital. The main advantages of these PPPs are (1) each firm takes advantage of its expertise; (2) line construction is faster and cheaper because the concession- aires are not constrained by the federal auctions law; and (3) assets are located within concession areas of these public firms, so they can more easily maintain the lines and substations after construction. Private investors have dominated transmission auctions both in terms of number of projects and levels of investment (Serrato 2008) (figure 3.3). From 1999 to 2007, private investors acquired 38 enterprises, while public firms acquired 17, and PPPs, 12. Their dominance is even more evident if we look at average revenue (RAP) bids—about R$26 million for private investors and only R$7.4 million for public firms. In fact, private investors received more than 75 percent of total auction revenues. Moreover, if PPPs are considered private, this percentage increases at least 7 percent, reaching more than 83 percent of the total RAP to private companies.1 Private Investors Dominate Auctions in Figure 3.3.a  and Average Revenue Offered Figure 3.3. b  Number of Firms Acquired (1999–2007) (1997–2007) 45 30 40 25 35 Enterprises 30 20 25 R$ 15 20 15 10 10 5 5 0 0 Private Public Private/Public Private Public Public/Private Source: Serrato 2008. 70 A World Bank Study Incentives to Promote Renewable Energy Brazil’s energy mix is largely renewable, with around 84 percent of electricity generated from renewable energy sources. Most electricity (77 percent) is pro- duced by large hydro power plants that utilize extensive freshwater reservoirs (figure 3.4). And hydro has far more installed capacity than any other energy sources (figure 3.5). But in recent years, nonconventional sources such as wind Figure 3.4  Renewables Lead the Energy Mix electricity generation by source Oil and derivatives 2.9% Nuclear 3.0% Natural gas 2.6% Coal 1.3% Wind 0.2% Biomass 5.4% Imports 8.0% Hydro 76.7% Source: EPE.

Renewable Energy Case Studies 71 and biomass have emerged—a response to new incentives, including feed-in tariffs, discounts, and auctions. Feed-in tariffs. The PROINFA. program, launched in 2002 was the country’s first scheme to foster renewable energy sources, although it was not consid- ered effectives and has been discontinued. It was essentially a feed-in tariff designed to contract 3,300 megawatts of wind, biomass, and small hydro by 2006. Each renewable source had a quota of 1,100 megawatts but a dif- ferent tariff. Electrobras (a state-owned holding company of power utilities) purchased the energy produced by participating plants through 20-year contracts, then resold the energy to all consumers in proportion to actual consumption. Consumers were entitled to portions of PROINFA energy in their contract portfolios. However, the program was criticized for lacking economic signals for efficiency and technological improvement and for poorly performing projects. Discounts. In 2007, Brazil established discounts on transmission and distri- bution for non-regulated (free) consumers (generally large industrial groups) who purchased energy through contracts backed up by renewable sources. In practice, the system is a cross-subsidy on the “wires� cost, paid by all captive consumers and received by the free consumers who purchase renewable energy. The incentive has been so effective that it has induced the installation of at least 700 megawatts of small scale renewable source based capacity in the period 2006–09 (mainly small scale hydropower, but also bioelectricity). The main criticism is that it introduces a market distortion because regulated consumers directly subsidize the incremental cost. Auctions. This mechanism was introduced to reconcile risk reduction for new investors with efficient energy procurement for regulated users. There are several types of auctions. One is for developing specific technologies or projects. Another type, known as “reserve energy auctions,� is aimed at increasing the reserve margin and ensuring security of supply. The reserve auctions are fully specified by the government, including the definition of the technology (or project) and the demand volume to be contracted. The first technology-specific “reserve energy� auction was in August 2008 to contract new energy from sugarcane bagasse cogeneration (“bioelectricity�) for delivery in 2011 and 2012. It was motivated by the country’s ethanol “boom� in 2006/07, which fostered the expansion of the sugarcane production and the installation of hundreds of new ethanol mills that were set to start operations between 2009 and 2012. Approximately 60 percent of the gross capacity was sold in the auction (1,500 megawatts or 4,800 gigawatt-hour per year) for an average price of US$80 per megawatt-hour. The net energy cost to the consumer—which depends on the expected revenue resulting from participation in the spot market—is expected to reach US$50 per megawatt- hour assuming a yearly energy spot price of about US$30 per megawatt-hour over the contract term. Some 2,700 gigawatt-hour per year of bioelectricity is still available to be sold in future auctions or directly to free consumers. 72 A World Bank Study A similar auction to contract wind power for delivery in 2012 was carried out in December 2009, when the government tried to take advantage of lower equipment costs (resulting from the global financial crisis) to develop wind- based generation on a larger scale (figure 3.6). The 20-year energy contract had an accounting mechanism designed to provide investors with a fixed pay- ment (for financing purposes) while managing the quantity-price risk and incentivizing/penalizing production above/below a given firm energy thresh- old. In this contract, investors offer a reference price value (megawatt-hour per year) and consumers pay a fixed value for the production ex-ante. The “reference value� is monitored, and penalties or incentives for over and under production are applied. The final average price was US$82 per megawatt- hour, 22 percent below the initial price, and lower than what most analysts had estimated. About 1,800 megawatts of capacity was traded, with a diverse mix of investors (local and foreign private generators, manufacturers, and government-owned companies) winning the contracts. Three new wind turbine factories are to be installed. In August 2010, a new reserve energy auction for renewables was carried out. An installed capacity of 2,900 megawatts was contracted, including 70 wind farms, 12 sugarcane cogeneration plants, and 7 small hydros. The con- tracting of wind-based capacity reached 2,050 megawatts at an average rate of US$75 per megawatt-hour. Biomass came to 713 megawatts at an average rate of US$82 per megawatt-hour and small hydro power reached 132 megawatts at an average rate of US$81 per megawatt-hour. How do the PROINFA and renewable energy specific auctions compare? Although the annual costs of both mechanisms is practically the same (around US$1 billion), the energy auction scheme is expected to deliver 20 percent more total capacity with an average 25 percent lower energy cost and an expected 60 percent lower tariff. In the case of bioelectricity, plants acquired through the auction scheme exhibited higher efficiencies. However, the very low prices (in the lower bound, but not outside the range of international feed-in tariffs) that have resulted in the renewables auctions Figure 3.6  Wind Generation in Brazil is on the Rise 1,400 1,200 Gigawatt-hour 1,000 800 600 400 200 0 00 01 02 03 04 05 06 07 08 09 20 20 20 20 20 20 20 20 20 20 Year Source: EPE 2011. Renewable Energy Case Studies 73 raise concerns about whether bid winners will be able to construct plants and profit from them. Although the auction system includes a number of pre- requisites to avoid speculative behavior among participants and lower the risk of construction delays or no construction of facilities at all, the use of a rele- vant set of financial, technical, and operational guarantees is still lacking. Nevertheless, as of August 2010, Brazil has successfully conducted 31 auc- tions for existing and new energy, with about 26,000 megawatts of new capacity contracted for delivery dates between 2008 and 2015, and contract terms rang- ing from 15 to 30 years. This includes about 8,700 megawatts of new renewable capacity and 17,500 megawatts of large hydro plants in the Amazon region. Of the total new generation capacity, 49 percent has been allocated to hydro resources, 44 percent to thermal resources, and the remaining 8 percent to biomass and wind power. The Case of Peru Electricity Market Reforms From 1991 to 1993, Peru undertook a major restructuring of its power sector that reflected regional and global trends—unbundling the national electricity utility into three main segments: generation, transmission, and distribution. The rationale was to include the private sector to gain higher levels of efficiency and service quality, but leave the public sector responsible for policy formulation and regulation. Private companies emerging from the 1992 reforms made substantial invest- ment commitments that were fulfilled in the following years. Investment figures reached their highest levels in the period 1996–99, then declined after the transition period (figure 3.7). High levels of investment led to annual average increases in installed capacity of 9.2 percent, a rate that was not matched by higher demand (annual average increases of only 4.7 percent). Investments in transmission and distribution led to increases in coverage from 53 percent in 1993 to 76 percent in 2004. However, the privatization push came to an end in May 2002, when under strong regional opposition and public outcry, the government cancelled the privatization of Egasa and Egesur, the two public-owned generating companies serving Arequipa, Moquegua and Tacna. At this point, generation (90 percent of companies) and transmission (100 percent) are managed to a great extent by private enterprises (figure 3.8). But in distribution, public (48 percent of invest- ments) and private (52 percent) investment are almost even. Institutional responsibilities rest on the Ministry of Energy and Mining and the Regulator of Private Investment in Energy (OSINERG). The former is responsible for approving concessions, sector planning, and rule-making. The latter is accountable for implementing the tariff structure. Law 26.734, which is the statutory instrument of OSINERG, establishes the regulator’s responsibility, which is to oversee service quality, efficiency, and investment commitments. 74 A World Bank Study Figure 3.7  Privatization Led to an Investment Surge in the Second Half of the 1990s total investment in electricity in Peru (US$ million) 800 700 600 500 400 300 200 100 0 95 96 97 98 99 00 01 02 03 04 05 06 07 08 19 19 19 19 19 20 20 20 20 20 20 20 20 20 Year Generation Total investment Distribution Transmission Source: Ministry of Mining and Energy of Peru Sector Eléctrico en Peru, various years.

Generation By 2009, total system generation was 30,915 gigawatt-hour. The main energy source is hydropower, representing close to 63 percent of all the electricity gen- erated (figure 3.9)—a high percentage but far lower than the record hit in 2001, when it represented 89 percent. The turnaround for hydro began in 2002 with the discovery of major natural gas reserves in Camisea. Since then, the share of Renewable Energy Case Studies 75 Figure 3.9  Hydro and Natural Gas Dominate Generation by type of fuel (GWh) Hydro 63% Natural gas 31% Oil 3% Coal 3% natural gas-fired thermal generation in the country’s energy mix has shot up from about 10 percent in 2001 to 31.1 percent in 2009. Coal accounts for a 3.1 percent share, and oil, 2.9 percent. Over the past decade, electricity power demand has jumped from 2.621 megawatts in 2000 to a peak of 4,322 megawatts in 2009, although the recent financial crisis has slowed the rise somewhat in 2008/09. Electricity consump- tion has also risen sharply—in fact, more quickly than for demand—from 15.546 gigawatt-hour in 2000 to 27,249 gigawatt-hour in 2009, but a slowdown in this growth is similarly evident in 2008/09 because of the financial crisis. Between 2012 and 2020, it is estimated that Peru will need to increase to 6,140 megawatts to handle demand that is growing by 9 percent per year. The Peruvian electricity sector is strongly linked and dependent on natural gas from the Camisea gas field, with relatively large reserves. Although legally the hydrocarbon sector is part of a competitive market, the government has a strong interest in setting policies for internal consumption and prices, and condi- tions for exporting. The Camisea natural gas price for internal use in power generation is one of the cheapest in the region, essentially a discounted internal price for all types of consumption, especially power generation. This low level creates a distortion in the power market that discourages developing alternative generation like hydro- electricity—as well as the efficient use of natural gas in thermal power generation, such as through combine cycle units. As table 3.3a.a shows, the 2008 Camisea natural gas price for power generation for each of the four main thermal power plants (either in or close to metropolitan Lima area) is around US$2.2 per million British Thermal Unit (BTU). This price, as table 3.3b shows, is below that of other countries and the resulting electricity energy cost for combine-cycle units. Camisea’s installed capacity has skyrocketed thanks to low prices (see figure 3.10). 76 A World Bank Study Table 3.3a  Lima-Based Gas Prices Average only US$2.2 per Million BTU . . . natural gas prices for power generation, 2008 (US$/MMBTU) Item Ventanilla Santa rosa Chilca Kallpa Field 1.3065 1.3753 1.3753 1.3961 Transport 0.7398 0.7398 0.7392 0.7402 Distribution 0.1218 0.1218 0.0 0.0 Total 2.1681 2.2369 2.1145 2.1363 Table 3.3b.  Far Below that of Other Countries and Costs for Combine-Cycle Units natural gas prices (site of generation) (US$/MMBTU) Gas price, Corresponding CCGT generation Country (US$/MMBTU) variable cost, (US cents/kWh) Vietnam 3.20 2.24 Georgia (imports from GAZPROM) 3.50 2.45 Azerbaijan (imports from Russia) 6.77 4.74 USA, October 2007 Henry hub spot price 7.02 4.91 Source: Mercados. In addition, recent preliminary World Bank’s studies2 indicate that the eco- nomic netback price (at the field) for Camisea natural gas that is used for alter- native processes (other than power generation)—like petrochemical, liquefied natural gas, or industrial use) are in the range of US$5 per One Million BTU (MMBTU) for liquefied natural gas3 (for supply to Mexico) to about US$9 per MMBTU for industry replacing liquid fuels. The thermal generation production cost is about 3.5 cents of US$ per kilowatt-hour, making most potential hydro- power projects uncompetitive. The official Ministry of Energy and Mining (MEM) energy policy is that the promotional internal price of Camisea natural gas should be maintained at least for the period (5 years) stipulated in the renegotiated contract with the pro- ducers (which allows for no more than a 5 percent increase in the price of natural gas annually, and not larger than the percentage increase of liquid fuels), and after that, the annual increases should be lower than the percentage increase of liquid fuels. In any case, the initial price gap will persist in the future. This price policy applies to the initial fields of Camisea (known as lots 88 and 56), but not to any other exploitations of natural gas fields in the same area of Camisea or in other places. Transmission The transmission of electricity in Peru is provided by seven private enterprises. In 1998, the grid was integrated with the construction (through a Build- Operate-Transfer (BOT) concession) of the Mantaro-Socabaya transmission line,4 which unified the two largest grid systems. After the unification, the government established the National Interconnected System, which included 20 out of the 24 states of Peru, with annual energy production of 18.800 giga- watts and a total demand of 2.800 megawatts. The main transmission network Renewable Energy Case Studies 77 Figure 3.10  Camisea’s Installed Capacity Has Skyrocketed Thanks to Low Prices 1,400 1,313 Natural gas installed capacity (MW) 1,200 1,000 942 800 600 468 400 340 200 0 04 05 06 07 20 20 20 20 Year Source: World Bank 2008. is composed of 220 and 138 kilovolt lines, with a total length of 9,771 kilome- ters, about 60 percent of the overall length of 16,319 kilometers of the transmission network. Incentives to Promote Renewable Energy In Peru, 63 percent of energy is generated from renewable sources, mainly hydro, with wind power at 0.7 percent. The share of renewables thus has fallen as the share of thermoelectric power has risen. However, renewable energies are receiv- ing strong support from the government, motivated by anticipated higher power demand, a still low level of access in rural areas, climate change commitments, and energy security—and the government wants renewables to account for 33 percent of generation by 2021, up from less than 1 percent now, if large hydro is excluded. In May 2008, the government issued Decree 1002 establishing incentives for promoting renewable energy—which cover solar, wind, biomass, geothermal, tidal, and small hydro—but not large hydro. These incentives include: • Renewable energy quota. The government established a 5 percent mandatory quota for the period 2008–13. The quota has to be updated every five years • Auctions. The investor is guaranteed a fixed price during the 20 years of the contract • Preferential treatment. Developers have priority access to the transmission and distribution grids • Tax incentives. A program of accelerated depreciation for renewable energy projects. Peru has dived into promoting renewables—for which there is enormous untapped potential (especially in solar and wind)—with technology-specific 78 A World Bank Study contract auctions for renewable energy based on targets set by a government- approved development plan (Barroso 2011). So far, the government has held two auctions (Maurer and Barroso 2011). The first call was in 2008, when the country organized an auction focused on hydropower under 20 megawatts. The government managed to cover 68 percent of the required energy for wind, biomass, and solar technologies (OSINERG), but for hydroelectric stations, only 32 percent. As a result, the government issued a second call, during which it had to adjudicate a 18 megawatts hydroelectric project. The remaining participants were disqualified due to offers with higher prices than those set by OSINERG, and quotas for biomass and hydro were not filled (figure 3.11). For the second auction in February 2010, OSINERG awarded 26 projects to supply 500 megawatts from renewable energy over 20 years, with projects in biomass, wind, solar, and hydro under 20 megawatts. This first call was regarded as a great success by sector investors, given the certainty it provides on future cash flows for any given project. In June, OSINERG released consolidated bidding rules for a second auction for late 2010, with an expected supply of an additional 338 megawatts of hydro, as well as requirements for up to 419 and 8 gigawatt- hour per year from biomass and solar, respectively. Winning generators were awarded contracts with distribution companies (to be passed-through to regu- lated consumers) for up to 20 years to deliver the annual amount of energy offered at its agreed price for three years ahead (Barroso 2011). As in the Brazilian case, demand pays a fixed annual amount and collects the spot market revenue.

Renewable Energy Case Studies 79 By 2011, eight renewable energy-based generation stations were producing electricity for the National Interconnected System (seven of them started oper- ations in April 2010 and the eighth began in July 2010). The rest of the projects will start by the end of 2012. Out of the total energy that will be produced by the successful bidders, 30 will come from biomass, and the rest from small hydro. Renewable energy tariffs have been covering 100 percent of the costs and expected benefits of the projects, with income originating from the sale of electricity in the short-term market plus additional fees paid by consumers. The Case of Mexico Electricity Market Reforms The electricity sector in Mexico is mostly state-owned. With the exception of generation, where there is 25 percent of private sector participation, the rest of the sectors are served by the state-owned company, the Federal Electricity Commission (CFE). CFE has an installed capacity of 46,686 megawatts in 218 power plants and an estimated number of 22 million consumers. CFE defines the investment program with the lowest cost for the electricity sector, with a 10 year planning horizon. It is also responsible for planning, construction, and operation of the national electric system and is subject to government regulation and supervision by the Mexican government. Generation Mexico’s energy mix is dominated by fossil fuels (figure 3.12). In 2010, electricity generation was 241,491 gigawatt-hour, with two-thirds coming from hydrocarbons. Natural gas has been the main fuel used for producing electricity, with its share rising from 14 percent in 1998 to 48.8 percent in 2008—while the share of fossil fuel fell from 51.7 percent in 1998 to 18.3 percent in 2008. Meanwhile, Mexico has been gradually boosting the share of renewable energies—which reached 18.01 percent in 2010. Of the country’s total genera- tion, 15.2 percent comes from hydroelectricity, 0.07 percent from wind, and 2.74 percent from geothermal. After Mexico’s debt crisis in 1994/95, it began to open up the fully state- owned power sector to private investors again, and in recent years, private sector investment in electricity has risen sharply. In 2008 the private sector, either under the form of self-provision or cogeneration, contributed, respec- tively, 6.7 percent and 4.5 percent of the country’s total installed capacity. Of the total private investment in electricity, more than 90 percent is foreign, and that percentage rises to close to 100 percent for foreign investment in the sector of independent producers and exporters. Private sector producers apply 11 technologies, the most used being combined cycle technology (70 percent). Within the private sector the energy mix is composed of natural gas (81 percent), other solid fossil fuels (15 percent) and renewable energies 80 A World Bank Study Figure 3.12  Mexico’s Energy Use Is Dominated by Fossil Fuels but Renewable Are Growing electricity generation by sourcea (GWh) 250,000 200,000 Gigawatt hours 150,000 100,000 50,000 0 10 99 00 01 02 03 04 05 06 07 08 09 20 19 20 20 20 20 20 20 20 20 20 20 Year Coal Combined cycle Geothermal Hydro IPPs Nuclear Thermal Wind Source: SENER. a.

Independent producers represented 59.9 percent of total installed capacity. For regulation purposes, electricity generation is divided into two types: public service and not for public service. Public service is the generation of electricity to distribute among consumers. Not for public service is divided among (1) self- provision; (2) cogeneration (production of electricity together with thermal or another type of secondary thermal energy); (3) independent production (genera- tion of electricity from a station with a capacity higher than 30 megawatts, des- tined exclusively to CFE or for export); and (4) small production (electricity sold to CFE, which is less than 30 megawatts or for export within those limits and/or electricity generated for small communities under 1 megawatts). Electricity transmission For Mexico, congestion in transmitting electricity poses a major challenge, amounting to an estimated loss of US$1.4 billion per year. But it also creates a potential incentive for using power generated by local markets. Some areas, such as the Yucatan peninsula, remain particularly isolated because their only links to the main national grid are small congested lines. According to Rosellon, this problem will become more severe in the near future because national demand for transmission capacity keeps growing (Rosellon 2006). The rate of capacity Renewable Energy Case Studies 81 Figure 3.13  Transmission Lines Are Getting Longer 60,000 55,000 50,000 Kilometer 45,000 40,000 35,000 30,000 01 02 03 04 05 06 07 08 09 10 20 20 20 20 20 20 20 20 20 20 Year Source: SENER. growth has ballooned over the past decade, rising from about 4 percent between 1981 and 2001 to more than 20 percent between 2002 and 2006. The length of transmission lines has shot up from around 35,000 kilometers in 2001 to 50,000 kilometers in 2010 (figure 3.13). Transmission tariffs in Mexico are set according to the cost of service per megawatt-mile. This method provides no proper effective incentives for expanding the grid and relies instead on a subjective way of allocating costs among consumers according to their so-called presumed impact on the grid (Rosellon 2006). Using this method, charges for transmission services for ten- sions equal to or greater than 69 kilovolt are calculated as the maximum between “fixed costs plus variable costs� and “operation and maintenance costs.� Administrative fixed costs—which are basically the long-run incremental cost of the transmission network—are then added to this amount. They are allocated among consumers of the current grid and consumers of the future expanded grid according to their impact across the entire network. Incentives to Promote Renewable Energy In the early 2000s, when Mexico wanted to diversify its fossil-fuel dominated fuel mix and promote the use of renewable energy, its Energy Regulatory Commission established different regulatory instruments—in the form of con- tracts and incentives—aimed at increasing renewable energy penetration in the system. The key ones are: • Interconnection contract. This is the main instrument to regulate the terms and conditions of the interconnection between the national system, the renewable energy developer, and the electricity provider. It allows the sur- plus of electricity produced by licensees in a given month either to be sold to the electricity provider in that particular month or to be stored at the Energy Bank of the national electricity utility for its use or sale during the next 12 months 82 A World Bank Study • Electricity Transmission Agreement. This was established to allow the transpor- tation of electricity from the renewable energy source to electricity providers • Tax incentives. Income tax payers who invest in electricity generation from renewable energy can deduct 100 percent of the investment as long as they operate the machinery for at least five years. In 2008, Mexico passed the Law for the Promotion of Renewable Energies and the Financing of Energy Transition. The law’s overriding objective is to promote the use of renewable energy for purposes other than utility services. As a result of the law, the government has also established the National Strategy for Energy Transition and the Promotion of Sustainable Energy. Over the past decade, the increase of renewable energies in Mexico, espe- cially wind technologies, has involved significant levels of private sector invest- ment (figure 3.14). In fact, the private sector has been responsible for 76 percent of total investment in wind projects, according to Mexico’s Secretary of Energy. This investment is occurring at the level of self-generation. In 2006, Mexico implemented an “open bid� system—known as the Open Season approach—to expand its transmission grid by connecting wind energy to the national electricity system. The first agreement was between the publicly owned enterprise (the Federal Electricity Commission) and the private industry to build 145 kilometers of transmission lines from La Ventosa to the sub-station Juile. How does this new approach work? The public utility determines trans- mission infrastructure needs given initial private sector interest in developing wind power (both self-supply and PPA commercial schemes). A transmission plan is then presented to wind power developers to gauge their interest in reserv- ing firm transmission capacity. After details are agreed, a final plan is prepared Figure 3.14  Private Investors Lead the Way in Wind Power committed wind projects in Mexico by ownership, MW 818 Number of projects 398 396 280 304 203 1.4 0.6 83 94 99 07 09 10 11 12 19 19 20 20 20 20 20 Year Public Private Source: SENER. Renewable Energy Case Studies 83 and an “open season� starts, requesting formal commitments for firm transmis- sion capacity reservations. Renewable energy developers must provide guarantees, in the form of letters of interests, based on the following conditions (1) 5 percent of the estimated cost of the Open Season must be paid at the same time of the presentation of the company’s expression of interest, (2) 25 percent of the total cost must be paid once government authorization takes place, and (3) 100 percent must be paid one month before the beginning of the tendering process. The utility commits to building the necessary infrastructure to connect the total capacity of wind projects to the electricity grid. The open season approach “pools� transmission costs, which are shared among wind power developers (costs are not passed to customers). The Mexican authorities consider the open season approach a success. Since its establishment in 2006, there has been an exponential growth of wind energy development, moving from almost negligible levels before then to about 250 megawatt-hour in the 2007–09 period (see figure 3.15). In April 2010, Mexico’s energy regulator (CRE) published a new methodol- ogy to calculate the transmission costs of renewable energy projects. The regulation will require the state power company CFE to charge around US$2.5–5.0 per megawatt-hour depending on the voltage, to transmit electric- ity from renewable and cogeneration sources on the national power system. Previously, the tariffs were not standardized and required CFE to hire an expert to conduct a study on the site. The protocol brought a lot of uncertainty to investors about what the final price would be to pay CFE for transmission. Depending on the specific conditions of each project, this new methodology could cut rates as much as 50 percent.

The case study evidence suggests that: • There is a significant trade-off between effectiveness and efficiency of alterna- tive instruments for deploying renewables. Feed-in tariffs tended to be quite effective but to be set on the high side, reducing incentives to cut costs and posing significant strains on already stripped national budgets. Competitive auctions, on the other hand have tended to be efficient but initially low and not always the most effective instrument • Countries can scale up renewables following different paths. For Brazil, the move from feed-in tariffs to auctions enabled it to both reduce costs and deploy additional capacity. Peru followed in Brazil’s path, opting for auctions instead of introducing feed-in tariffs. On the other hand, China’s move from competitive tenders to feed-in tariffs allowed for discovery effects to deter- mine the right level of prices to attract private investment in renewables • Private investors require technical and regulatory certainty about the avail- ability of renewable-ready transmission resources if they are to finance investments. The traditional reactive model of transmission regulation— developing transmission on a first-come, first-served basis—is not conducive for renewables, as it introduces extensive regulatory and technical uncer- tainty about whether adequate transmission will be available once the resource is generated, and transmission distances for renewables can be large. The case of China is quite telling in that the sharp increase in renewables (particularly wind) posed challenges to the stability of the transmission sys- tem. In contrast, Mexico used an open season approach, with new transmis- sion investment decided through an agreement between the Federal Electricity Commission and private investors, which facilitated better regula- tory and technical certainty. Notes 1. Some assessments stress the limitations of the Brazilian auction system (Dutra and Menezes 2005). According to this line of argument, the Brazilian system is affected by what they call “higher costs of reforms in developing economies� because of a lack of trust in both government and institutional design issues. 2.

The analysis of the key determinants of the private investor’s decision to enter is done using the probit model, where the dependent variable is a dummy equal to 1 if PPPs were introduced in the relevant segment of the market (respectively in generation, renewable based energy, transmission and distribu- tion, transmission, distribution) and 0 if not (see table C.1). Table C.1  List of Dependent Variables Variables Definition 1. PPP introduction (probit) Generation = 1 since the year of establishment of the first PPP in generation Introduction of PPP in GEN = 0 otherwise = 1 since the year of establishment of the first PPP in renewables Introduction of PPPs in RE = 0 otherwise = 1 since the year of establishment of the first PPP in fossil fuels Introduction of PPPs in FF = 0 otherwise T&D = 1 since the year of establishment of the first PPP in transmission and distribution Introduction of PPP in T&D = 0 otherwise = 1 since the year of establishment of the first PPP in transmission Introduction of PPP in TRA = 0 otherwise = 1 since the year of establishment of the first PPP in distribution Introduction of PPP in DISTR = 0 otherwise 2. PPP investment (Heckman approach to sample selection) Generation PPP Investment in GEN = investment committed by the private sector in electricity generation (US$) PPP Investment in RE = investment committed by the private sector in renewable-based generation (US$) PPP Investment in FF = investment committed by the private sector in fossil fuel-based generation (US$) T&D PPP Investment in T&D = investment committed by the private sector in transmission and distribution (US$) PPP Investment in TRA = investment committed by the private sector in transmission (US$) PPP Investment in DISTR = investment committed by the private sector in distribution (US$) 107   108 A World Bank Study The treatment of the modeling of the key factors affecting the private inves- tor’s amount of investment sunk in the sector in the relevant segment of the market (respectively in generation, renewable based energy, transmission and distribution, transmission, distribution) (see the second part of table 2A.1) is based on Heckman’s approach to sample selection. This distinguishes between (1) the decision on whether to enter the segment of the electricity market (selection equation), and (2) the decision on how much investment to commit to (investment equation).1 Unlike the Tobit model, the factors that affect the two decisions need not be identical and, where identical, could even be differ- ent in the sign of their effect on the decisions. The selection equation relates the choice of whether to attract PPPs (via a zero/one dummy variable) as a function of the governance variables and the price of oil is estimated over the complete set of countries using a probit model. The second-stage equation, relating PPP investment to the full set of short-run and long-run variables described in table C.2, is estimated over the sub-set of countries.

This bias is related to the magnitude of the correlation between the errors (that include the omitted variables) in the selection and investment equations. Where there is no correlation between these errors, there is no selection bias. The direction of the bias depends on the sign of the inter-equation error correlation. The condition for identification of the Heckman estimation procedure is that the selection equation contains a significant variable(s) not included in the investment equation. The significance of the Mills’ ratio in the second stage indicates whether there would have been selection bias in its absence. If the Mills’ ratio is insignificant, a simple regression of the quantity of invest- ment on explanatory variables would be unbiased. The canonical Heckman model also assumes that the errors are jointly normal. If that assumption fails, the estimator is generally inconsistent and can provide misleading inference in small samples. Note 1. The data on the dependent variable consist of observations related to the investment. This would be zero for countries that had not attracted PPPs, and positive for those countries that had decided to use it. This observation is split into two components: a zero or one variable indicating the lack of entry or entry of PPPs, and a variable mea- suring investment for the subset of countries that attracted PPPs.
