The objective of the project is to facilitate and accelerate RPSI projects in developing countries around the world. The project will draw on international experience and theoretical analysis in this area to provide a framework to assess: � the economic, financial and environmental benefits that can accrue to regional power trading; � the institutional and regulatory arrangements needed to sustain and optimize regional projects; and � the ways in which obstacles to integration have been successfully overcome. The final output of the project will be an umbrella report, Regional Power Sector Integration – Lessons from Global Case Studies and a Literature Review. This review will summarize the 12 case studies and literature review undertaken and analyze common themes on barriers to RPSI and solutions to overcome them. Economic Consulting Associates was contracted to execute the project. In doing so, we are working closely with ESMAP and World Bank staff, as well as government officials, utility, power pool, and regional economic community personnel, and others directly involved in implementing regional power schemes. This and other 11 Case Studies are prepared as clear, factual presentations of the selected projects. The intent is to provide a direct, easily digestible description of each of the selected projects without imposing an analytic framework or making judgments about the degree of success. Such analysis will be undertaken at the global level, considering the entirety of experiences from the Case Studies, in the aforementioned umbrella report. All 12 Case Studies follow a uniform structure to facilitate ease of comparison and reference from one Study to the next. Some sections are longer than others, depending on the specifics of the Study. Additionally, there is some cross-referencing within each Study. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW vii ESMAP Briefing Note 004/10 | June 2010 Executive summary 1 Executive summary 1.1 Motivations/objectives for trade When PJM was started in 1927 as a power pool, the motivation behind the interconnection was to be able to share generation resources and thus improve efficiency as well as minimize investments in generation and transmission capacity of the three utilities involved. The resulting power pool allowed utilities in Pennsylvania and New Jersey to share load. Meeting power demands in Philadelphia was the primary motivation for creating an interconnection and trading energy. In 1956 the arrangements were extended to Maryland, which was when the arrangements were renamed as PJM. The essential beneficiaries of this arrangement were the utilities that formed the PJM pool. These benefits were gradually extended to more utilities in the Mid-Atlantic region of the USA. The 1973 energy crisis led to a rethink in federal energy policy and the setting up of the Federal Energy Regulatory Commission (FERC) as an activist regulator of interstate energy commerce. The consequent development of open-access competition allowed the establishment of independent generation that greatly increased demands on the wholesale pool. Another FERC initiative has been the development of independent system operators (and independent regional transmission organizations, RTOs). PJM was already independent because no single utility controlled it, but it was only formally declared an RTO in 2002. The RTO structure was followed by extension of PJM into a western region in 2002 with further expansion to the west and the south in 2004. Expansion of the control area highlighted the importance of longer-distance transmission development. 1.2 The trade solution put in place The initial arrangement of PJM was a simple power pool that sought to deliver least-cost dispatch of the mix of generation owned by the utilities in PJM.1 With the growth of the arrangements both geographically and by the inclusion of nonutility traders, the organizational structure evolved. PJM became substantially independent from its utility owners in 1993 and was converted into a not-for-profit limited liability company in 1997. Its current management structure is a two-tier arrangement with a management board supervising day-to-day operation and reporting to an elected Members Committee (MC). Election to the MC is arranged into constituencies representing the different member 1 Throughout this case study “PJM� refers to the entity “PJM Interconnection LLC� or else to its predecessor entity. More general references such as to the “PJM area� can cover other entities such as generators or utilities trading through PJM markets. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 1 ESMAP Briefing Note 004/10 | June 2010 Executive summary interests: transmission owners, generation owners, electricity distributors, end-use customers2 and pure traders. PJM members can trade bilaterally or else can self-supply, but additional energy and capacity needs are made available through PJM operation of specific markets in energy, capacity and ancillary services. These markets are supported by information provision and analysis tools developed centrally by PJM as well as an independent market monitoring company that ensures transparency and effective competition are in place to protect the interests of all members. The main markets offered are: � Day-Ahead Energy Market in which hourly locational marginal prices (LMPs) are calculated for the next operating day based on generation offers, demand bids and scheduled bilateral transactions bid into a day-ahead auction. � Real-Time Energy Market, which is a within-day spot market in which current LMPs are calculated separately from day-ahead LMPs. � Reliability Pricing Model, a capacity market model that works as a market for capacity three years out. It works in conjunction with PJM’s Regional Transmission Expansion Planning (RTEP) process. Its features are: � Procurement of capacity commitments for both generation and transmission through competitive auction; � Locational pricing for capacity that reflects constraints in the transmission system. � Financial Transmission Rights (FTR) auctions for participants to hedge their exposure to locational marginal pricing by buying FTRs that pay out differences between the prices at the entry and exit nodes of specific transmission paths. � Transmission services. PJM offers point-to-point firm and non-firm access services for specific bilateral routes from generators to loads. The fees for transmission fund PJM. 1.3 Current status and future plans PJM dispatches about 163,500 megawatts (MW) of generating capacity over 56,350 miles of transmission lines. More than 51 million people live in the PJM region. Since the opening of the regional wholesale market in 1997, PJM has administered more than $103 billion in energy. PJM delivers about 700 TWh of energy a year and serves utilities in 13 states as well as the District of Columbia. PJM has overseen an expansion in interstate trade with significant energy transferring from the states in the Great Lakes region of the USA to the deficit region of the fast-growing southern USA (i.e., Virginia and North Carolina) as well as to the heavily populated area of 2 Customers also compete in provision of demand management by contracting with their local utility. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 2 ESMAP Briefing Note 004/10 | June 2010 Executive summary the original PJM Mid-Atlantic region. It has done this essentially by providing market- clearing facilities in energy and capacity. PJM has ambitions to extend its area of operation by cooperation with neighboring system operators in New York and the Midwest. However, to fulfil these ambitions, PJM still needs to address issues of price differentials between regions. It set up its locational marginal pricing market in 1998. This provided pricing signals for location of generation and demand management as well as requirements for transmission investment. However, it also created local monopolies in generation, which it managed by capping generation bids during periods when congestion set differential prices. In 2007, PJM began operation of its Reliability Pricing Model, which operated as a buy auction for forward commitments to deliver new generation and transmission. It modelled locational signals to reward development in energy deficit areas. This model signals an acknowledgement that locational marginal prices in an energy market are not likely to deliver sufficient generation and transmission to ensure reliable operation of the system. However, the model still fails to deliver sufficient reward to transmission investment that relieves congestion, and so significant price differentials between regions persist.

PJM dispatches about 165,000 MW of generating capacity and delivers around 700,000 GWh of energy annually. Figure 1 shows both the utilities involved and their respective zones of operation. The PJM control area covers only parts of many of the states in which PJM operates. Therefore, when state-level statistics are cited in this study, it must be remembered that these cover more than just the PJM area. Economic environment Table 1 shows some economic indicators for the United States for the years 1965 and 2007 as well as selected current statistics for the states that wholly or partly participate in the PJM pool. In 1965 PJM first expanded to include more than the original three utilities. Because the PJM supply area covers only part of the territory of many of the states in which it has a presence, the numbers in Table 1 for the PJM states will tend to overstate the impact of PJM. The USA is a rich country with a fully developed electricity sector. The available data suggest that the states in the PJM area are very close to the US average on a number of measures.

Regulatory and political environment US economic development was based on an abundance of primary energy sources for most of the 20th century. Dependence on coal gradually gave way to oil during the early 20th century mainly due to relative convenience. The oil crisis of 1973 highlighted a growing PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 5 ESMAP Briefing Note 004/10 | June 2010 Context for trade dependence on imports of oil, and from then on there have been intermittent moves toward greater conservation and energy independence. In electricity, there is a long history of development of grid connections, starting with a Niagara Falls power scheme in 1883. Therefore, the development of PJM in 1927 was based on a US track record of grid connection for utilities. This initial development therefore occurred during the era of passive legislation on energy. The ownership structure of the electricity industry in America has changed over time. According to Tyson Slocum,4 the old model consisted of vertically integrated monopolies regulated by a cost-of-service price control. Then: “Deregulation was triggered by a series of federal actions over several years, followed by decisions by America’s largest states to pass laws ordering the separation of power plants from the distributional utility.� With separation of generation from distribution, states ceded regulatory authority to FERC (Federal Energy Regulatory Commission) over wholesale trading. In parallel with this, the energy crisis in the 1970s led to encouragement of alternative providers.5 This was further promoted by the Energy Policy Act of 1992, which gave FERC authority to order utilities to buy from independent utilities. Therefore, the regulatory environment broke down monopolies and encouraged trading companies to operate in a wholesale market largely free from state price controls. In the general political environment, electricity availability is taken for granted. The industry is considered mature and stable. Supply failures (e.g., the August 2003 failure that cut supply to 50 million people on the East Coast) and price spikes (e.g., the California crisis of 2000 and 2001) can occur, but this will not usually be due to true lack of availability. There was therefore no particular direct political or social driver leading to a regional power pool. The benefits of interconnection were mainly perceived by the utilities themselves. The driver for the PJM power pool therefore came from commercial interests. 2.2 Supply options Figure 2 gives energy resources, both indigenous and importable, for each of the states where some, or all, of the load is served by PJM. The data in Figure 2 give an indication of resource availability. For example, the gas energy imported is for all uses in the state and not just for electricity generation—there are no significant gas resources indigenous to the region. The figure shows: � There are significant surpluses of coal in Kentucky and West Virginia. � Washington DC, Delaware, Maryland, North Carolina and Tennessee have relatively little primary energy resource. 4 Slocum (2008, October) 5 Slocum cites the 1978 Public Utility Regulatory Policy Act as leading to this. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 6 ESMAP Briefing Note 004/10 | June 2010 Context for trade Nuclear and hydro play only a small part in available energy resources, with reliance mainly on thermal energy sources. The data suggest that there is advantage in electricity transfers from resource-rich areas to other areas, but it should be noted that availability of primary energy sources within a state and local generation are not vital to regional development—any resource needed can be readily imported. Figure 3 gives generation capacity in each main PJM region as of December 2008. It highlights the importance of steam generation (coal-fired) in the PJM generation mix, with the Western region relying significantly on coal mined in West Virginia and Tennessee, while the Mid-Atlantic region uses coal mined in Pennsylvania.

PJM accounted for about 54% of load in the states in which it operates, although there is considerable variation in PJM’s share in individual states. Demand growth averaged 3.3% per year in the states where PJM control areas in the PJM Mid-Atlantic region are located.

Figure 7 Regional Demand Forecast Source: PJM, “Load Forecast Report, 2009�7 2.4 Energy tariffs In theory, regional power pools and related cross-border power transfers will promote convergence of consumer prices between regions, especially for larger-scale industrial consumers. Figure 8 explores this by plotting prices for the different states in which PJM has a presence. The data have been adjusted to 2006 values using the US Consumer Price Index. Figure 8 does not indicate convergence of prices between states in the PJM area. Using the USA price for comparison, there is a persistent differential between states in the same region of the PJM area. There is also a persistent variation in price levels between PJM regions, with prices in the Mid-Atlantic region above the average for the USA, while in the Western and Southern regions of PJM, prices tend to be just under the USA average price for most states. 7 See Annex A2, Table 11 for definition of regions. The data used, including data for individual zones, are given in Table 12 PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 12 ESMAP Briefing Note 004/10 | June 2010 Context for trade Figure 8 Inflation-Adjusted Prices in PJM states (2006 = 100) Source: EIA The retail price in any particular area is made up from a wholesale energy price with additional costs for transmission, distribution and tax.8 In a common pooled area, the main expected convergence would be in wholesale prices. Wholesale energy pricing in PJM settlements is done via the bid-based locational marginal pricing (LMP) approach. The LMP approach calculates the cost of supplying the next unit of 8 In the PJM pricing methodology, the transmission costs are built into the wholesale prices.

By 1997 PJM had become a completely independent organization. At that time, membership was opened to nonutilities and an independent board of managers was elected. Also, in 1997, PJM opened its first bid- based energy market, and the Federal Energy Regulatory Commission (FERC) approved it as the nation’s first fully functioning independent system operator (ISO).11 In 2001 it became the nation’s first fully functioning regional transmission organization (RTO).12 Table 4 Chronology of PJM Development Year Event 1927 Three utilities in Pennsylvania and New Jersey realize the benefits of an interconnection and form a power pool. 1935 Federal Power Commission (created in 1930) becomes independent of government. Responsibilities included oversight of interstate electricity transfer and promotion of electrification. 1956 Baltimore Gas and Electric Company and General Public Utilities join the pool, which is renamed Pennsylvania-New Jersey-Maryland Interconnection, or PJM. 1965–1981 More utilities join; PJM continues being operated through the utilities. 1977 Federal Energy Regulatory Commission (FERC) replaces Federal Power Commission. 1978 Public Utility Regulatory Policy Act promotes energy procurement from 3rd party generation 1992 Energy Policy Act empowers FERC to order utilities to buy from independent utilities. 1993 PJM becomes a neutral, independent organization; formation of PJM Interconnection Association. 10 Utilities had started experimenting with least-cost dispatch once they had more than one power station, but this was the first where generation owned by different utilities was dispatched through a single dispatch process. 11 ISOs operate, but do not own, transmission systems in order to provide open access to the grid for non-utility users. 12 A Regional Transmission Organization (RTO) in the United States is responsible for moving electricity over large interstate areas. Like ISOs, they provide an open access system and operate but do not own transmission assets.

The resulting interconnection allowed Philadelphia Electric, Pennsylvania Power & Light, and PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 17 ESMAP Briefing Note 004/10 | June 2010 History of scheme Public Service Electric & Gas of New Jersey to share load. The first goal of the interconnection was to meet power demands in Philadelphia. More generally, the idea was to achieve economies of scale and to incorporate the benefits of diversity on both the generation side and the load side to drive down costs. When the three utilities signed the initial agreement it was based on an estimated savings of $45 million for the time period 1927 to 1935. PJM started out in 1927 as a simple agreement between utilities. The purpose of the power pool they created was to dispatch electric generating plants on a lowest-cost basis, thereby reducing the electric costs for all members of the pool. The initial pool had the city of Philadelphia as a primary load center with limited demand elsewhere in the region. Significant expansion of the geographic region began in 1965 and led to the initial more serious consideration of transmission issues. Further transformation of the rules of the organization became necessary in 1978 when access to third-party generation had to be accommodated. The current status as a regional transmission organization was approved in 2002, but the de facto operation of PJM Interconnection as an RTO can be dated from 1993 when the 1993 Operating Agreement was signed; this was later transformed into the current Operating Agreement when PJM converted from an association of utilities into a limited liability company. In its latest form, PJM Interconnection is a market operator that runs auctions and clearing markets that set wholesale prices for electrical energy, generating capacity, transmission capacity and several ancillary services. These markets cover both short-term energy markets and long-term capacity markets. In addition it undertakes long-term planning. 3.3 Feasibility studies done PJM regularly carries out planning and feasibility studies. The PJM transmission feasibility study process currently embraces: � 2008 Regional Transmission Expansion Plan Report http://www.pjm.com/documents/reports/rtep-report.aspx A central pillar of the PJM framework is the Regional Transmission Expansion Planning (RTEP) process, which identifies transmission system additions and improvements. Studies are conducted that test the transmission system against mandatory national standards and PJM regional standards. These studies look 15 years into the future to identify transmission overloads, voltage limitations and other reliability standards violations. PJM then develops transmission plans in collaboration with transmission owners to resolve violations that could otherwise lead to overloads and blackouts. This process culminates in one recommended plan—one RTEP—for the entire PJM footprint that is subsequently submitted to PJM’s independent governing board for consideration and approval. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 18 ESMAP Briefing Note 004/10 | June 2010 History of scheme � Mid-Atlantic Power Pathway (MAPP) http://www.pjm.com/documents/reports/rtep- report/~/media/documents/reports/2007-rtep/2007-section3b.ashx This is a major proposed transmission investment. PJM RTEP analysis assessed the impact of the MAPP project on area load deliverability violations that are expected to occur over the 15-year planning horizon. All such plans require PJM approval. PJM has a corresponding generation reserve planning process: � PJM Reserve Requirement Study, 2008 http://www.pjm.com/~/media/committees- groups/committees/pc/20081015-item-04-2008-pjm-reserve-requirement- study.ashx The annual PJM Reserve Requirement Study (RRS) calculates the reserve margin that is required to comply with the Reliability Principles and Standards as defined in the PJM Reliability Assurance Agreement. This study is conducted each year. The study focuses on the process and procedure for establishing the resource adequacy (capacity) required to serve customer load with sufficient reserve for reliable service. The results of the Reserve Requirement Study provide key inputs to the PJM Reliability Pricing Model (RPM). These values are used in the RPM auctions and are specifically used to determine the Variable Resource Requirement curve for the PJM Regional Transmission Organization (RTO). The Demand Resource Factor is used to determine the unforced capacity value of the two PJM load management products: Demand Resources that can be offered into the RPM auctions and Interruptible Load for Reliability that is nominated and certified prior to the delivery year. The results of the RRS are also incorporated into PJM’s Regional Transmission Expansion Plan (RTEP) process. 3.4 Assets built and planned resulting (directly and indirectly) from scheme itself In a scheme that has been in existence since 1927, all generation and transmission has been developed and renewed under the terms required for interconnection within the scheme. Looking ahead from the present, in the years to 2017, generation is planned to grow by 8% in the Mid-Atlantic region, by 5% in the Western region, and by 9% in the Southern region— an overall growth of 7%. Over that period, demand in the PJM region is forecast to grow by about 16%. The necessary generation additions which have been planned to 2017 are illustrated in Figure 10.13 13 Based on PJM “Reserve Requirements Study, 2008�; Table 9 in Annex A1 is replicated from the study.

The PJM Regional Transmission Expansion Plan (RTEP) is managed by the PJM Transmission Expansion Advisory Committee (TEAC) on an ongoing basis. The annual reports are summaries of plans approved in the preceding year.14 The 2008 Regional Transmission Expansion Plan Report states, “More than $13.2 billion of transmission upgrades and additions, representing over 1,400 distinct transmission projects ranging from 69 kV to 765 kV, have been authorized by the PJM Board since the inception of the RTEP process in 1999, through December 2008. About $11.3 billion of baseline transmission network upgrades across PJM ensure that established reliability criteria will continue to be met. At the same time, $1.9 billion of additional transmission upgrades will enable the interconnection of more than 45,000 MW of new generating resources and merchant transmission projects.� Figure 11 reproduces the current approved reinforcements. 14See 2008 Regional Transmission Expansion Plan Report http://www.pjm.com/documents/reports/rtep- report.aspx PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 20 ESMAP Briefing Note 004/10 | June 2010 History of scheme Figure 11 PJM Board-Approved Backbone Transmission Lines, 2008 Source: PJM 2008 Regional Transmission Expansion Plan Report, map 1.2, page 3.

There are five other reinforcements planned. 3.5 Interconnections and electricity trade Figure 12 shows the PJM Interconnection LLC high-voltage transmission system. The system is dispatched from the Greensberg and Valley Forge dispatch centers, which work in close cooperation. The entire control area is therefore effectively dispatched as a single integrated system.

However, this is just a part of the overall surplus energy being transferred from the Western region. As a day-ahead market, it cannot effectively support long-term bilateral energy contracts. This problem was resolved in the PJM area soon after the single LPM clearing energy market commenced in 1997. The Financial Transfer Rights market commenced operation in 1999. In Section 5.1 a description is given of how these work to allow effective long-term bilateral contracts between participants in different regions or control zones. 3.6 Environmental and social issues US environmental policy is implemented at the federal level by the Environmental Protection Agency (EPA). Until 2009, both state and federal environmental policy have been mainly restricted to rules governing pollution levels. Over its history, environmental policy and renewable generation have played a very small role in development in the PJM area. However, in 2009, proposed connections of 48 GW of 16 The PJM data give some transfer information for individual Western region control zones but not for the core PJM area of the Mid-Atlantic region, where all the statistics are presented in amalgamated form. Therefore, this analysis has been restricted to inter-regional transfers.

Nearly all proposed renewables are wind farms. If all the proposed renewables capacity is built, it will make a considerable contribution to output, noting that current total installed capacity connected to PJM is 165 GW.17 PJM is tracking renewable generation contributions and produces what it calls a “Dashboard� summarizing contributions since 2005.18 It shows that, although hydro is the biggest contributor to renewables generation (7.1 TWh in 2008), wind is the fastest-growing technology. Even so, renewables will not have a significant impact on PJM operations for some time to come, and no significant plans have been made by PJM related to the ensuing reserve and dispatch issues that may arise. 17 Caution is needed in interpreting connection proposals—many proposals will not end up being developed. 18 Renewable Energy Dashboard. http://www.pjm.com/about-pjm/newsroom/renewable-dashboard.aspx PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 26 ESMAP Briefing Note 004/10 | June 2010 Institutional arrangements 4 Institutional arrangements 4.1 PJM governance arrangements 4.1.1 Overview The PJM governance structure has evolved as the nature of the organization has changed. This section describes only the current arrangements. PJM Interconnection LLC is a fully developed independent system operator (ISO) operating across state boundaries and covering the territories of several transmission owners. As a limited liability company incorporated in Delaware, it comes under that state’s jurisdiction, but for all practical purposes, it is regulated first by the Federal Energy Regulatory Commission (FERC) and also, for some issues, by the independent state regulatory commissions. The governance structure is set out in, and put into effect by, the Operating Agreement that each market participant must sign. This then gives the market participant voting rights (unless joining as an affiliate or in a limited capacity) on the Members Committee. 4.1.2 Governance structure Figure 16 PJM Organizational Structure Source: Based on PJM Operating Agreement PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 27 ESMAP Briefing Note 004/10 | June 2010 Institutional arrangements PJM’s governance structure was set up in such a way as to allow the ISO to have independence from the pressures of market participants in its decision-making process. To achieve independence, PJM relies on a two-tiered structure that includes a fully independent non-stakeholder Board of Governors (the PJM board) and a sectoral Members Committee to provide advisory support. PJM Board The PJM board consists of nine voting members plus the president. It is responsible for maintaining system reliability and creating and maintaining competitive markets which do not allow any member or group of members to exert excessive influence. The PJM board is also in charge of operational matters. Members of the board cannot be affiliated with any party that has signed and is part of the PJM operating agreement. The Members Committee elects board members from a slate of candidates prepared by an independent consultant, not by the PJM members. Members Committee The Members Committee (MC) consists of five sectors, which operate as electoral colleges. A member must decide in which sector its major interests lie (but other members can challenge where they believe that a member is in the wrong sector). The sectors represent the major types of participation: � Transmission owners—there are currently 58 (15 are voting members and the remainder are affiliates) � Generation owners—117 (61 are voting members) � Electricity distributors—42 (35 are voting members) � End-use customers—26 (14 are voting members) � Other suppliers (i.e., traders and others that do not fit into another category)— 292 (224 are voting members).19 The MC reviews and decides upon all major changes and initiatives proposed by committees and user groups and provides advice and recommendations to PJM on all matters relating to: � The safe and reliable operation of the PJM grid, � The creation and operation of a robust, competitive and nondiscriminatory electric power market, and � Ensuring there is no undue influence over PJM’s operations by any member or group of members. 19 The Operating Agreement describes “other suppliers� as traders in energy or capacity products who do not fit into any of the other categories. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 28 ESMAP Briefing Note 004/10 | June 2010 Institutional arrangements The Members Committee meets at least annually. Committees Committees are classified as senior committees and other committees. PJM’s two senior committees are the Members Committee (MC) and the Markets and Reliability Committee (MRC). The MC provides advice and recommendations to the PJM board and the Office of the Interconnection on all matters relating to the safe and reliable operation of the PJM Control Area, the creation and operation of a robust, competitive and nondiscriminatory electric power market, and ensuring no undue influence over PJM’s operations by any member or group of members. The MRC reports to the MC, as provided in the PJM Operating Agreement. Other PJM committees monitor specific tasks on a continuing basis. These committees report to the senior committees. Members appoint representatives to each committee. Sectors have one vote each on senior standing committees. Secretariat, administration and budget PJM Interconnection has a full-time secretariat known as the Office of the Interconnection. The senior officers are: � President, who supervises the Office of the Interconnection and is appointed by the PJM board on an annual contract � Secretary � Treasurer According to the 2008 financial report, PJM Interconnection had an income of $241 million. PJM has about 600 employees. 4.1.3 PJM operations Planning PJM operates an ongoing transmission planning function with a rolling 15-year planning horizon. As already noted in Sections 3.3 and 3.4, this is called the Regional Transmission Expansion Plan (RTEP). PJM maintains a standardized planning approach supervised by the Transmission Expansion Advisory Committee (TEAC). This committee reports to the PJM board for investment approvals. The planning methodology is developed by the Regional Planning Process Working Group (RPPWG), which evaluates and makes recommendations to the Members Committee (MC) to reform the present interconnection queue and study process. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 29 ESMAP Briefing Note 004/10 | June 2010 Institutional arrangements Planning is governed by the standards set by the North American Electric Reliability Corporation (NERC).20 Some additional regional reliability standards may also apply. NERC standards relate to continuity of performance of the interconnected system. This means that there is no economic test governing the cost of any constraint. Therefore, investments are made to ensure that the reliability standards are met and are not driven by price differentials in markets either side of a constraint. Markets PJM operates as an independent neutral operator of distinct electricity markets, with defined market rules. It provides analytical tools to its members as well as trading infrastructure in support of these markets and publishes operational data. This section gives an overview of the markets set up. More details about the operational rules of the markets are given in Section 5.3. The main markets PJM operates are: � Day-Ahead Energy Market. This is a forward market in which hourly locational marginal prices (LMPs) are calculated for the next operating day based on generation offers, demand bids and scheduled bilateral transactions. Appended to the Day-Ahead Energy Market are the Operating Reserve Business Rules, which incentivize bidding close to expected real-time operation. � Real-Time Energy Market. This is a spot market in which current LMPs are calculated at five-minute intervals based on actual grid operating conditions. Real-time prices are available. PJM settles transactions hourly and issues invoices to market participants monthly. � Reliability Pricing Model. This is a capacity market model that works as a market for capacity three years out. It works in conjunction with PJM’s Regional Transmission Expansion Planning (RTEP) process. Its features are: � Procurement of capacity three years out through a competitive auction; � Locational pricing for capacity that reflects constraints in the transmission system. � Financial Transmission Rights (FTR) auctions. FTRs are financial instruments that entitle the holder to a stream of revenues (or charges) based on the hourly congestion price differences across a specific transmission path in the Day- Ahead Energy Market. � Synchronized Reserve Market. Load-serving entities can meet their obligation to provide synchronized reserve to the grid by using their own generation, by purchasing it under contract with another party or by buying it on the Synchronized Reserve Market. � Regulation Market. Load-serving entities can meet their obligation to provide regulation to the grid by using their own generation, by purchasing the required 20 http://www.nerc.com/ PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 30 ESMAP Briefing Note 004/10 | June 2010 Institutional arrangements regulation under contract with another party or by buying it on the Regulation Market. � Transmission services. PJM offers point-to-point firm and non-firm access services for specific bilateral routes from generators to loads. The fees for transmission fund PJM. They are set out in the PJM Open Access Transmission Tariff document.21 In 2008, PJM further supported market operation by spinning off its market monitoring unit into an independent company called Monitoring Analytics.22 Dispute resolution procedures PJM has defined dispute resolution procedures set out in Schedule 5 of its Operational Agreement. It includes mediation and arbitration processes. Arbitration decisions will be filed with the Federal Energy Regulatory Commission (FERC). The PJM Operational Agreement is bound by US contract law. 4.2 Role of national governments and regional institutions The US Department of Energy (DOE) is in charge of “advancing the national, economic and energy security in the United States� (www.energy.gov). US federal policy on energy markets has been driven by various energy acts. The most important is possibly the Energy Policy Act of 1992. This gave wide powers to the Federal Energy Regulatory Commission (FERC), which has interpreted its role as encouraging the concept of the regional transmission organization (RTO). However, the development of the energy and capacity markets set up by PJM has been driven mainly by its members’ interests. Individual states continue to have jurisdiction over retail tariffs. 4.3 Regulatory agencies The Federal Energy Regulatory Commission (FERC) was created through the Department of Energy Organization Act in 1977, when the Department of Energy was also established. Its predecessor, the Federal Power Commission, was abolished and its duties divided between FERC and the Energy Department. FERC is an independent agency that regulates the interstate transmission of electricity, natural gas, and oil. FERC’s responsibilities with respect to electricity markets include: � Regulation of transmission and wholesale sales of electricity in interstate commerce 21 http://www.pjm.com/documents/agreements/~/media/documents/agreements/tariff.ashx 22 www.monitoringanalytics.com PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 31 ESMAP Briefing Note 004/10 | June 2010 Institutional arrangements � Licensing and inspection of private, municipal, and state hydroelectric projects � Ensuring reliability of high-voltage interstate transmission system � Monitoring and investigating energy markets � Using civil penalties and other means against energy organizations and individuals who violate FERC rules in the energy markets � Overseeing environmental matters related to natural gas and hydroelectricity projects and major electricity policy initiatives � Administering accounting and financial reporting regulations and conduct of regulated companies. In the 1990s, following the Federal Energy Regulatory Commission (FERC) Order 880 that began the deregulation of the traditional utility companies, FERC began to develop the concepts of an independent system operator and a regional transmission organization, which allowed third-party entities to manage functions of the electric grid that were traditionally responsibilities of vertically integrated utility companies. PJM was designated an RTO by FERC in 2001. FERC regulates PJM and approves its open access transmission tariff for the wholesale electricity market. FERC is not involved with regulations for retail electricity tariffs, physical construction of electric generation, transmission, or distribution facilities nor the regulation of nuclear power plants (a task governed by the Nuclear Regulatory Commission). 4.4 Role of outside agencies The North American Electric Reliability Council (NERC) is a transnational organization covering the United States as well as utilities in Mexico and Canada. It has no direct effect on trading within the PJM area but sets operational standards with which PJM must comply. There are no other outside agencies of significant relevance to PJM. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 32 ESMAP Briefing Note 004/10 | June 2010 Contractual, financial and pricing arrangements 5 Contractual, financial and pricing arrangements 5.1 Contracts The primary contract governing PJM is the Operating Agreement, which is a civil contract between utilities. This defines membership of the market. However, the governance structure accommodates different types of member interests because there are effectively different types of contracts reflecting the different types of businesses participating in PJM. Energy contracts At the core of PJM is an agreement between mainly integrated utilities with both generation and load in a specific geographic area. The effective energy contract types recognized within the PJM area are: � Self-supply. Internal transfer from each utility’s own generation to its own load- serving entity (LSE).23 This accounted for 65.2% of all notified consumption in 2008. This is backed up by self-scheduling of a significant proportion of generation (43.1% in 2008).24 � Bilateral contract. This is a transfer of energy between utilities in different zones. Bilateral contracts accounted for 14.6% of energy consumed in 2008. � Spot sales. Utilities bought 20.1% of their energy requirements through the PJM Day Ahead Energy Market in 2008.25 Pricing in self-supply or bilateral contracts is a private matter between the utilities involved, although the existence of the spot market will affect the pricing decisions made.26 Capacity contracts—generation Load-serving entities (LSEs) have an obligation to provide generation capacity commitments sufficient to meet their share of predicted peak-hour demand. These generation commitments can be sourced from: � Own generation resources 23 A load-serving entity delivers energy to consumers. LSEs may be separate businesses but can also be the load- serving function of an integrated utility. 24 Data are based on the Monitoring Analytics 2008 State of the Market Report, Volume 2 http://www.monitoringanalytics.com/reports/PJM_State_of_the_Market/2008/2008-som-pjm-volume2.pdf. The reason why self-scheduling is so much less than self-supply is because some self-supplied capacity must still be offered into the day-ahead spot market if it has been developed with a forward commitment as defined under the PJM Reliability Pricing Model. 25 Small volumes would also have been bought or sold in the real-time market 26 Regulated companies will want their contracts for purchase of energy taken into consideration when setting regulated tariffs but the average wholesale spot prices will be the main benchmark used by the regulator when asked to approve tariffs, especially in the case of self-supply PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 33 ESMAP Briefing Note 004/10 | June 2010 Contractual, financial and pricing arrangements � Contracts for generation capacity � Capacity credits purchased in the capacity credits market. The LSE obligation is locational; the generation must be physically deliverable at the relevant offtake point (i.e., any transmission needed from a remote location must be included in the declared commitment). The PJM capacity credit contract was developed in 2007. Part of the planning process involves running the Reliability Pricing Model (RPM), which determines requirements for additional generation capacity (including reserves) and transmission upgrades as well as the locational price differentials that should be applied. Generators offer forward commitments to deliver energy from specific resources in a forward year in one of the following ways: � Base residual auctions. These are held in May for delivery in three years time. The capacity sold at auction is allocated to load-serving entities in the form of Financial Transmission Rights with price differentials determined by the RPM. � Incremental auctions. Up to three are held in the years between the base residual auction and the delivery year. The first and third incremental auctions cover adjustments to the amount of capacity in the forward commitment due to delays, cancellations or re-rating of the physical resource offered. The second incremental auction covers changes in the locational demand for resources between the base planning year and the delivery year. � Bilateral contracts. This market allows generators to procure resources to cover forward commitments made and allows LSEs to hedge against inadequate resource commitments. Additional generation resources and those covered by auctioned forward commitments can be sold in this secondary market. Bilateral contracts can be firm or non-firm. The non-firm contract is one where the seller only offers the capacity during periods where there is no congestion setting a differential energy price on the relevant point-to-point pathway. Capacity contracts—transmission Financial Transmission Rights sold as forward commitments are allocated to load-serving entities in proportion to their peak demand levels. FTRs for generation that is not committed forward will also be allocated to LSEs in the same way. An FTR is essentially a right to transfer a certain volume of energy between two physical nodes on the system. As the name implies, this is a financial right rather than a physical right. The value of the FTR is an offset of locational marginal prices derived from the spot market. LMPs are described in Section 5.3. FTRs are tradable in the secondary market. 5.2 Ownership and finance PJM Interconnection LLC is a limited liability company that owns no generation or transmission resources and never takes ownership of any of the energy transferred across the control area. It is a not-for-profit service provider to its members. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 34 ESMAP Briefing Note 004/10 | June 2010 Contractual, financial and pricing arrangements The structure of ownership of generation and transmission/distribution assets varies considerably. Figure 17 shows that most energy is distributed and supplied by a small number of integrated utilities in the states in which PJM operates. However, these utilities are predominantly investor-owned. Only in the Mid-Atlantic region are competitive independent providers significant in energy delivery. The large numbers of publicly owned (including federally owned) and cooperatively owned utilities fail to have a significant impact on retail delivery volumes, although their impact at the very local level is significant for the consumers served. The integrated utilities are the main owners of the transmission and distribution infrastructure and will be responsible for all investments in transmission. Figure 17 Ownership Structure of Load-Serving Entities, 200727 Source: EIA Table 5 shows generation ownership in the different states. In the Mid-Atlantic region, nearly all the generation is owned by independent producers, but in the other regions, utilities own their own generation to a much greater degree. Therefore, in the Mid-Atlantic region most of the energy will be purchased under bilateral contract or from the spot market rather than by self-supply. It should be noted that the utilities in the Western and Southern regions did not join PJM until 2002 or later. This may be a contributory factor in the differing generation ownership structure in comparison with the more established Mid-Atlantic region. 27 See Annex A4, Table 14 and Table 15 for background data PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 35 ESMAP Briefing Note 004/10 | June 2010 Contractual, financial and pricing arrangements Table 5 Sales by Generation Ownership Type, 2007 Source: EIA 5.3 Pricing arrangements 5.3.1 Pricing principles Wholesale prices and ancillary service prices should be set by competitive markets that are transparent and well informed. Analytical tools are supplied by PJM to help traders value all products. Generation should recover most of its fixed costs through contracts priced in the energy markets. However, the subsequent development of the Reliability Pricing Model suggests lack of faith in the ability of the market to deliver the required investment in the necessary time frame. One reason why insufficient investment may be forthcoming is that bidding in the day-ahead market is constrained to 10% above cost where congestion applies in order to limit local monopoly power of generation upstream of a transmission constraint. There is a forward market for generation to commit to deliver and this provides some of the revenue for new generation investment. This same mechanism provides revenue for incremental transmission investments. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 36 ESMAP Briefing Note 004/10 | June 2010 Contractual, financial and pricing arrangements The cost of congestion is allocated to the parties who need to import energy across the congested route. However, the Reliability Pricing Model determines the amount and hence the value of extra capacity needed to provide secure operation of the system. The parameters of the model determine how much new generation and transmission capacity is needed, but it seeks to localize the costs of providing that capacity. The Reliability Pricing Model seeks to provide signals for merchant transmission investment but so far such independent investors have been very limited. Fundamentally, PJM operates on the basis of short-run marginal costs and so does not seek to reduce price differentials between regions. The effect of its price signalling mechanism is to incentivize generation close to demand rather than incentivizing additional transit—the mechanisms for rewarding such transmission investment are not properly developed. Synapse Energy Economics reports:28 “There has been no significant merchant transmission activity within PJM, demonstrating that market signals alone are inadequate to produce such investments. The reasons for this are well understood. First, the presence of new transmission would reduce or eliminate the congestion costs (price signal) upon which the new transmission would depend, at least in part, to recover its embedded costs. Second, the benefits of such investments in terms of reduced transmission congestion are widely shared, and individual entities are reluctant to shoulder the burden themselves if there is no straightforward mechanism for sharing the cost.� PJM mechanisms set wholesale prices. Retail prices are largely regulated and are set by state regulators. 5.3.2 Pricing mechanisms Energy Energy pricing in PJM is done via the bid-based locational marginal pricing approach. The LMP approach calculates the cost of supplying the next unit of energy at a specific location taking into account generation cost, transmission congestion and losses. Essentially, if there is no transmission congestion, LMP prices should not differ over a given area. LMP pricing is meant to ensure open, transparent and nondiscriminatory transmission of energy. LMP prices are set in the Day-Ahead Energy Market. All generators with capacity available (i.e., capacity not sold outside the PJM region, or as self-supply or under bilateral contract) must offer the capacity into the Day-Ahead Energy Market. Generation capacity that has been sold with a forward commitment contract (as described in Section 5.1) must be offered into the Day-Ahead Energy Market regardless of whether it has been sold under bilateral contract. Load-serving entities can offer demand-side bids into the market but will mainly be nominating the volume of energy they wish to buy in the Day-Ahead Energy Market. Generators are free to set any price for their offers into the Day-Ahead Energy Market and are not constrained by costs. Monitoring Analytics LLC provides an annual market 28 Hausman et al. (2007) http://www.appanet.org/files/PDFs/SynapseLMPElectricityMarketsExecSumm013107.pdf PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 37 ESMAP Briefing Note 004/10 | June 2010 Contractual, financial and pricing arrangements monitoring report29 that investigates the extent to which market power may have been exercised in the setting of LMPs by generators. The PJM system operator will then produce a market-clearing, least-cost schedule and will use curtailments on specific generation to assess the contribution of that generation to the marginal cost of serving load at each node. Generators are paid the LMP at their local transmission node, and LSEs pay the LMP at their local transmission node. PJM’s system operators conduct dispatch operations and monitor the status of the grid using telemetered data from nearly 74,000 reporting sites. PJM prepares extensive emergency and routine contingency scenarios, taking into account variables that could affect supply and demand such as weather conditions and emergency situations as well as the potential of equipment failures along with daily and seasonal demand fluctuations. Capacity pricing With the energy market setting locational marginal prices, Financial Transmission Rights are made available for load-serving entities (LSE) to hedge the fluctuating cost of spot energy. FTRs are initially allocated to LSEs based on an assessment of peak demand, but they are tradable. The initial cost of an FTR is derived from sales in the auctions for forward commitments, but their value will be derived from the differential in LMP set for the node where the generation is injected into the system compared to the LMP set for the node where the demand is offtaken. Although there are option products on offer, the FTR financial flows are derived from the price differential between nodes regardless of the direction of energy flow. Therefore, a party holding an FTR for a particular delivery route from Node A to Node B can pay a penalty if the LMP at Node A is higher than the LMP at Node B. FTRs are paid out or charged out regardless of whether energy has flowed under contract along the nodal route of the FTR. Ancillary services PJM Interconnection also currently operates two markets for ancillary services: � Synchronized reserves. This service supplies electricity if the grid has an unexpected need for more power on short notice. The power output of generating units supplying synchronized reserve can be increased quickly; demand resources can also bid to supply synchronized reserve by reducing their energy use on short notice. Load-serving entities can meet their obligation to provide synchronized reserve to the grid by using their own generation, by purchasing it under contract with another party, or by buying it on the Synchronized Reserve Market. � Regulation. This service corrects for short-term changes in electricity use that might affect the stability of the power system. It helps match generation and 29 Monitoring Analytics (2008b) http://www.monitoringanalytics.com/reports/PJM_State_of_the_Market/2008/2008-som-pjm-volume2.pdf PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 38 ESMAP Briefing Note 004/10 | June 2010 Contractual, financial and pricing arrangements load and adjusts generation output to maintain the desired frequency.

PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 39 ESMAP Briefing Note 004/10 | June 2010 Future plans 6 Future plans PJM is essentially a service provider to its members. Its growth and longevity are testimony to the services provided being useful to its members. As a service provider, it seeks to incrementally provide new tools and markets in which they can trade. The development of new markets and risk management tools make PJM the most sophisticated electricity trading market anywhere in the world. The most significant recent development has been the Reliability Pricing Model (RPM), which links into PJM’s regulatory obligation to plan and invest for future needs for reliable transmission and generation services. It satisfies this requirement by auctioning forward commitments to develop new facilities. However, it should be noted that the locational marginal pricing market that began operation in 1998 was intended to provide full incentives for investment in transmission, generation and demand-side response. The Financial Transmission Rights market that was introduced two years later effectively quantified the value of locational signals.30 The introduction of the RPM signalled a belief that insufficient investment signals would come from the short-run energy market alone. PJM has periodically expanded its membership since its inception. This fits into plans by FERC to develop a network of large regional transmission organizations to replace state- integrated utilities. Currently, PJM is one of the five RTOs. For individual states, transmission should be operated by an independent system operator (ISO) according to the intentions of the Federal Energy Regulatory Commission (FERC). There are currently two ISOs. PJM has been in discussion with the Midwest Independent Transmission System Operator (MISO)31 and the New York Independent System Operator (NYISO) about amalgamating markets. There is no doubt that PJM offers a service valued by its member utilities. However, it is not designed to equalize pricing between utility areas. During times of economic hardship, this could be seen as a defect by politicians who may be loath to allow what they might perceive as excess profits flowing to monopoly businesses in local areas. This will limit the ability of future utilities to participate in PJM. Going forward, the continuing challenges to PJM will include: � Meeting future changes in federal energy policy. The new presidency has ambitions to develop renewables and put more emphasis on conservation measures. Operation of a grid in which large volumes of wind are dispatched will put strains on existing market mechanisms, which rely on the system operator to provide physical balancing and to allocate costs of doing so fairly generally. More precise balancing incentives may be needed in the future. � Socialization of transmission investment costs. It seems clear that reliance on short-run locational marginal cost signals means that price differentials will 30 Locational marginal prices provide a single spot price covering both energy and locational generation and transmission costs. 31 Despite its name, this should be classed as an RTO. PJM Innterconnect (PJM) Case Study REGIONAL POWER SECTOR INTEGRATION: LESSONS FROM GLOBAL CASE STUDIES AND A LITERATURE REVIEW 40 ESMAP Briefing Note 004/10 | June 2010 Future plans persist. The mechanism for rewarding specific transmission investments seems to be inadequate. The rewards for generators in low-cost regions selling to consumers in high-cost regions are not therefore being fully realized by those generators. Outside of PJM’s role as a wholesale transmission services provider is the development of retail competition. This is a challenge for regulation in the USA. The focus of competition policy has hitherto been driven by utilities that have little interest in allowing competing retailers within their delivery areas.
