V1MATU ISSUS AM OPTIONS IN THI ENERGY SECTOR SUIIMARY Overview and Priorities 1. The devalopment of Vanuatu's energy sector is constrained by a number of inherert features. These factors include: (a) the fragmentation of the energy supply system and the energy consumption pattern as the natural result of the geography of a small decentralized ieland economy; (b) the small size of the market for commercial energy, particularly electricity and petroleum products; (c) the shortage of skilloA manpower and expertise at all levels of Government which prevents the efficient monitorJ"; _: current energy supply and makes the formulation of a development strategy difficultt (d) the severe financial constraints faced by the Government, both in terms of recurrent and development expenditures; and (e) the dominant and largely unregulated position of outside energy suppliers, particularly in the electricity and petroleum subsectors. 2. The most apparent results of these constraints are: (i) the high cost of commercial energy, and (ii) a weak Government position in the promotion of national priorities when conducting a dialogue with major energy supplieri. While these drawbacks may cause the continuation of a perhaps suboptimal pattern of energy supply, there are no easy solutions to these problems, many of which are generic ones of an island economy. The best improvement possibilities lie in a twofold approachs first, the introduction of imrovements within the existina institutional and suoplv framework. using the contractual and reaulatorv tools alreadv at the Governmentls disoosal. This would include the exercising of the full regulatory and shareholder rights already provided under the electricity supply franchise agreement with the private supplier, and the encouragement of more vigorous competition in petroleum product supply, perhaps through an increase in Government imports for domestic marketing, or through a resumption of an informal regulatory dialogue based on sound cost information. Secondly, the strenothening of the GveQagnt's exmertLse and stock of skilled human resources for the reaulatorv dialague with 2rivate ener=v sucoliers This would mean a significant strengthening and full staffing of the Bnergy Unit in the Ministry with electricity and petroleum specialists, and the appointment of qualLfied persons that enjoy full Government support as Electricity ComL$isoner and Union Electrique de Vanuata (UNELCO) board member. -ll- 3. Beyond the immediate need to assert economic prioritiAs within the existing structure, the long-term priorities call for the development of indiaenous enerav resources, if economically justified. The first steps in this respect will have to be the fzrming up of information on these resources, namely the study of (i) the potential for petroleum development in accessible offshore areas, (ii) the feasibility of the Sarakata and Teouma hydropower sites for electricity supply to the main urban cer.ers, and (iii) the availability of geothermal steam for power generation. The hydro and geothermal generating possibilities depend to a large extent on the pace of power demand development in Port Vila and Luganvilles fast growth in the tourism and small industrial sectors could advance the time when such investments are justified by the overall volume of demand. Current expectations, however, make it unlikely that new non-diesel generation sources will be needed before the year 2000. The potential for petroleum development, on the other hand, should be explored at the earliest possible time, as any hydrocarbon finds would enable the country to improve its trade balance. neray ConsumDpt.on 4. About 70% of total national energy consumption is accounted for by biomass-based fuels, primarily fuelwood for cooking. Another 25% of total consumption consists of petroleum fuels, mainly used ir the transport aactor. While domestic consumers are responsible for almost half of energy consumption, other large shares of consumption are taken up by agricultu-ial consumers for export crop drying, and by the transport sector. 5. Given the vigorous growth of diesel use in the transport sector, i' is likely that further growth in the ccnsumption of this product will exceed the expected economic growth rate signi'icantly. Other petroleum prod cts are likely to follow the GDP growth rate more closely. Electricity consumption in the dynamic Port Vila area can also be expected to register healthy growth of about 7% per year, while the Luganville demand center is less likely to show growth unless major new loads materialize. The use of biomass fuels in the domestic sector is expected to increase at the most in line with population growth, but lts consumption in the agricultural sector is likely to decline with the decrease of copra and cocoa exports. On balance, therefore, an increased penetration of petroleum fuels and electricity is likely, while the sbare of biomass-based fuels will decline slowly. Energv SuPD1V 6. Petroleum Products. The three major supplying companies import and distrlbute small amounts of products, constrained by both demand levels and the shallow access to the ports. Larger product volumes could be imported at lower prices, but additional storage and deeper port accese channels would have to be provided. The dlitributlon to locations other than the main ports takes place in drums, which leads to high cost, high losses, and difficult transport arrangements. 7. Eleotrlolty. UNELCO, a privately owned utility, operates an efficient system 3f urban supply based on diesel generation. The system is well-run, but the sball scale and the cost-plus nature of the franchise contract lead to high prices for consumers. Expansion plans for the future -iii- call for an lncrease of the d'-eel generatlng capacity, whlle alternatlve souroe of generatLon are evaluated. The supploer has formed a joLnt-vontur company wlth the Government to develop attractlve hydroelectric sites, when the demand will have reached levels that allow sufflclent economies of scale. The 5arak%ta hydro slte on Santo island could be justLfLable lf developed to a mLnimum o..paclty of 1 MW. a sLze that the power demand ln Luganvlle may reach by 1996. other potentlal hydro sltes on Efate and Malakula islands ned more study; while Malakula is more attractlve than Ifate, both do not appear attractlve ln comparLson wlth other alternatlves such as diesel, or local copra waste cogeneration, whlih should be studied in more detail. S. New and Renewable Eneray. The potentLal biomass energy supply li plentiful and could be used economlcally, together with solar energy, in the more remote locations of the country. Liomass gaeLflers, lf operated wlthln a ouitable LnstLtutLonal structure, could be competitive for local eloctrLclty generation on a small scale ln selected eLrcumstances. BLimass cogeneratlon at the large copra estates could be an alternotlve to local small diesel production of electrLcity. Finally, solar water heatLag and photovoltalo electricity generatlon for small lndlvldual uses could be attractlve if compared to the high cost of dellverLng petroleum products to outer islands, and maintainLng dLesel sets. Policy and nsatilutional Issues 9. The main Lssues arLiLng ln the development of the energy *ector ln Vanuatu are those concerned wlth the cost and prLcLng of energy, the instltutlonal and regulatory framework, and the potential environmental impacts (a) the power supply franchLis agreement provides for a prioLng formula that allows the passing on of most cost changes to conoumers, but does not appear to have any Lncentlves for cost mLnlmLzatLon or effLcLency increase I/ Cost reduction elements and incentlves to pursue energy conservatlon campalgn ;ould be lncluded ln the supply contract; (b) The wholesale margLns of petroleum product suppliers have been increasLng steadlly over tlim as competition is limited in the small Vanuatu market. Z/ CompetLtLon could be encouraged if the Government would expand its current dlrect Import to include ome local marketing in parallel wLth the established dLstrlbutors. Alternatively, a dLalogue on the cost structure should be resumed wlth the oil companies; (c) While, in princLple, the Government has access to detailed information from the power utliLty, in praottce the monltoring if By mld-1992, the Government had taken some steps to revise the tarLff formula. 2/ ay mld-1992. the Governmeut had plans to exert some control over petroleum prlces. and regulation of the power utility le inadequate. The Government needs to exercise its rights and responsibilities under the existing franchise arzangements fully, such as by appointing an Electricity Commissioner and an UNELCO board mc,berl (d) Cost reductions in the import and storage of petroleum products can be achieved by a relocation of storage facilities to a port area that is accessible for larger vessels with a full load; (e) Exploration for the possible hydrocarbons resources in offshore basins, and for the geothermal potential on Efate Island, will only go ahead if appropriate assistance is sought to develop attractive exploration and development packages to attract international companies; and (f) A:.though no major environmental problems are evident at this -Lme there is a lack of legal and regulatory provisions to deal .h an* problems from petroleum handling. lea -.d battery rposa.:, or diesel generating plant operation. If the hydro tes are 'eveloped, a careful environmental assessment will be neceeaLary. I. ECONOMIC AND INSTITUTIONAL FRAMEWORK Enerav and the Economy 1.1 The Republic of Vanuatu, known as the New Hebrides prior to independence in 1980, is an archipelago of some 80 islands, with a land area of about 12,000 square kilometers, and a population of about 143,000 (1989 census). More than half of the country's land area and population are concentrated in the three largest islands (Espiritu Santo, Malakula, and Efate). The only significant urban centers of the country are the capital Port Vila on Efate, and Luganville on Espiritu Santo, a total of about 26,000 people. The remainder of the local (ni-Vanuatu) pcpulation lives in scattered settlements on both major and minor islands of the archipelago with limited communication links to the urban centers. 1.2 The geographic fragmentation is paralleled in the economy which shows a sharp distinction between the modern sector, based on plantation a.riculture, tourism, government services, and offshore finance, and the traditional sector (comprising a large majority of the population), consisting mainly of subsistence agriculture. The modern sector is almost exclusively urban-based, with the exception of some of the copra, coffee, cocoa, and livestock enterprises in rural areas. Measured GDP, dominated by services, has been growing by about 2.51 p.a. in real terms between 1985 and 1989 (about equivalent to the population growth rate!, resulting in a per capita GDP of close to US$ 1,000 in 1989 (Annex 1.1). As expatriate income is well above average, the per capita income of the ni-Vanuatu population is likely to be significantly below this figure. 1.3 Vanuatu's trade balance is heavily negative at the level of about US$ 40 million (Annex 1.2). Although net inflows from services and private transfers dim..nish rhis negative balance, the current account deficit remains at about 201 of GDP, requiring a heavy dependence on foreign grants. Gross imports of petroleum products are equivalent to &bout 401 of domestically produced exports: however, as about 301 of imported petroleum products are re- exported as aviation fuel sales to international airlines, the net burden of product imports on the balance of payments is about 25Z of exports. 1.4 Government projections for the Vanuatu economy call for relatively modest growth of about 2-2.51 p.a. during the next few years, perhaps increasing to about 51 thereafter. The growth of tourism and other services, which drives overall economic growth, will be affected by the softer Australian economy and the appreciation of the Vatu vis-a-vis the AustraliarL dollar. Copra production and export, one of the traditional mainstays of the economy, is likely to stagnate or decline as world prices fall and the subsidies from the stabilization fund are phased out. Energy consumption growth is likely to be concentrated on tourism-oriented diesel use for power generation and marine transport, while the potential for alternative fuels such as copra production waste will be limited by the decline of the plantation industry. -2- 1.5 The impact of energy sectot constraints on economic development in Vanuatu is felt primarily through the high coat of energy. The causes of generally high energy price levels are twofolds first, the fragmented energy consumption pattern leads to complex distribution system, with a high potential for losses. Petroleum products, for example, have to be procured in small quantities, and are delivered to remote locations in drumss a system that encourages evaporation and loss of drums, and contributes to the high unit cost of fuel. Simlarly, electricity has to be supplied to isolated demand centers by high-cost small diesel facilitios rather than by more efficient larger generating capacity that could supply a bigger grid. Secondly, the supply of electricity and petroleum products is domitated by largely unregulated international csmpanies. The three major suppliers of petroleum products avoid competition and operate with high margins, and the private holder of the monopoly franchise for electricity supply to the two urban centers operates under a long-term cost-plus contract. Although limited m asures can be taken to enhance competition and increase supply efficiency, Vanuatu is likely to remain a high-cost energy supply location. 1.6 High energy prices Influence Vanuatu's development In a number of ways: (i) an extension of electricity service or easier transport links to remote rural locations are prevented by the high cost of such Investments; (ii) it is difficult to provide infrastructure to lca-income urban or perl- urban areas without subsidies from a financially constrained exchequer; (ii') the modern sector of the economy faces the obstacle of high electricity and petroleum product prices in setting up new manufacturing or service facilities. While it is difficult to quantify the degree to which energy price considerations are affecting investment, It is evident that the tourism sector is already becoming leos competitive vis-a-vis other Pacific destinations because of the escalation of other costs. Institutional Structure 1.7 The Vanuatu energy seccor is characterized by a weak Government capability to monitor -he sector and largely unregulated activities of private energy suppliers. The cabinet portfolio for energy coordination, hitherto based in the Ministry of Trade, Comerce, Cooperativeo, Industry and Energy, has been moved recently to the Prime Minister's Office.' Key senior staff dealing with energy matters, however (includi ., che Ministry's "Energy Unit"), remain in the Ministry.2 The responsibilit4 'ar elements of energy sector policy are split between the Ministry of T , (responsible for administering the franchise of the private power supplia.e fELCO), the Dep.. ment of Geology and Mines (responsible for the wpitream evaluation of hydrocarbon and geothermal resources), the Department of Torestry, the Planning and Statistics I/ In September, 1991, It was reportedly moved to the Ministry of Energy again. 2/ By mid-1992, the Energy Unit had been moved to the Ministry of Natural Resources. -3- Office, the Busir;ess Licensing Office, and Local Government (responsible for local diesel generation). 1.8 The Energv Unit of the Ministry of Trade, theoretinally responsible for energy sector coordination and analysis, is severely und#'staffed. Only two professional positions are currently filled, a staffing level which is inadequate to handle the regulatory responsibilities of the Government. Although grant funds become available from time to time to establish a temporary presence of resident advisers, it will be essential to strengthen the Unit on a permanent basis by increasing the number of professionals, some of them perhaps on a less than full-time basis, or for limited periods. Skills such as petroleum cost analysis, power sector regulation, and Pat.-t 7 planning would improve the Government's ability to conduct a meaningfu.- regulatory dialogue with energy suppliers. 1.9 The bulk of electricity is supplied by Union Electrique de Vanuatu Limited (UNELCO-Vanuatu), a subsidiary of Lyonnaise des Eaux, a French-owned firm based in Paris. The remainder is provided by small isolated distribution grids based mostly on small diesel generation sets and operated by local governments. Remote individual consumers such as schools, hospitals, and resorts often provide their oQn power supply from diesel sets or solar installations. UNELCO and the Government have recently formed a jointly owned company, Hydro Power Development Limited, designed to prepare and construct future hydro generating facilities. 1.10 UNELCO was originally granted a monopoly concession by the Condominium Powers in 1939 to operate as a public power utility in Port Vila. This was subsequently renewed for a 14-year period in 1974. In November 1982, GOV authorized UNELCO to transfer the concession agreement and its associated "Cahier de Charges" to "UNELCO - Vanuatu" jointly owned by UNELCO and Socivan, one cf~ UNELCO's subsidiaries. Similarly, on Santo Island, Compagnie d'Electricite de Santo (CES), which was 85S owned by UNELCO, was responsible for public power supply in Luganville until 1990. 1.11 In October 1986, GOV renewed the agreement with UNELCO and extended its concession up to 2011. As a part of this agreement UNELCO has also taken over CES. Thus UNELCO is currently sole4' responsible for public electricity supply in both Port Vila and Luganville. The terms of the original concession which exempted UNELCO from payment of taxee on capital equipment, spares, land and fuel had not been extended to UNELCO ANTO. UNELCO is therefore continuing to pay taxes on the automoti- ^ diesel oil (ADO) used for power generation in Luganville. 1.12 The franchise contract with UNELCO, the private power supplier in Port Vila and Luganville, provides for a Government counterpart in regulatory matters, namely the Electricity CommissicpnX. This position has not been filled, and the resulting simultaneous involvement of different counterparts on the Government side contributes to a lack of Government leverage vis-a-vis the supplier. Similarly, the nomination of a Government representative on UNELCO's board, an entitlement since the recent purchase of 10 of UNELCO equity by the Government, has taken a long time to materialize. In view of the Government's intention to increase its share to 302 in future, the appointment -4- of both the Electricity Cowmissioner and the Board Member are essential early &reps to assert the regulatory responsibility. In contrast, the lack of electricity supply legislation is not a key obstacle as the system La small and simple. The best hopa for an improvement in the efficiency of regulation lies in the full u,e of the lnstruments alreadg at the Gjvernment's disposal, such as the appropriate consultation and reporting clauses in the franchise agreement, or the Government's shareholder rights in the supply company. 1.13 The import and distribution of oet,roleum oroducts is handled by Shell, Mobil, and BP, with the exception of some direci imports for Governmnt use. The market is small and competition between suppliers is limited. Boral Gas Co. operates a mouest distribution system for LPG for urban household use. Petroleum product suppliers are not subject to regulation or legislatioi eith the exception of normal busines3 licensing proced_-es. II. ENERGY CONSUMPTION The Structure of Enertv Consumption 2.1 Total energy consumption in Vanuatu is estimated at about 57 mtoe for 1989. This represents a decrease in the net domestic consumption as compared to the 1985 estimate of about 70 mtoe. The primary reason for the decline is the drop in copra production and the simultaneous improvement in the energy efficiency of copra drying_3I. ot the total national consumption, approximately 701, or about 40 atoe, is comprised of biomass based fuels of which the primary component is fuelvood used by the domestic sector for cooking. The other major componeit of energy consumption is petroleum based fuels accounting for about 16 mtoe. Of this, about 13 mtoe, or approximately 80Z, is utilized in the transport sector either In the fatm of gasoline, automotive dieqel or lubricants. Approximately 6.7 mtoe of ADO is consumed by the utility sector to generate electricity. The net electricity available for consumption Is equivalent to about 2 mtoe after accounting for conversion, transmission and distribution losses. A summary of the estimated 1989 Vanuatu energy balance and a graphical illustration of sectoral energy consumption is presented in Annex 2.1. 2.2 Domestic Sector: The domestic sector accounts for the largest component of energy consumption, equivalent to approximately 46Z of the national total. Of the total annual domeatic (household) sector consumption of about 26 mtoe, 951 is biomass based fuels, 31 is petroleum fuels in the form of kerosene and LPG, and only 21 is electricity. The electricity consumption is almost exclusively limited to expatriate and high income urban households in the Port Vila and Luganville service areas. A very small fraction of rural center electricity is produced but data on energy consumption and sectoral consumption for these rural centers are not presently available. The estimated total domestic sector energy consumption increased approximately 18Z since 1983 which is equivalent to the increase in total population during t.,is period. 2.3 Agricultural Sector: The agricultural sector accounts for the next largest component, equivalent to 261 of the total annual national energy consumption. The majority of the energy consumed by the agricultural sector is in the form of biomass fuels used for crop drying. An undetermined but small quantity of petroleum fuels is also consumed in the agricultural sector for process heat and electricity generation. The petroleum used for process heat is used to supplement crop drying in the copra and coffee processing operations Qf the large estates. Petroleum used for electricity generation Is primarily for household consumption of estate managers and supervisory employees and, In some cases, to operate crop drying equipment. Petroleum is 31 It is estimated that 65 percent of the copra produced for export Is now dried using "hot air" driers fueled with wood, husks and shells. In 1983, only 15 percent of the copra was dried with hot air driers. Hot air driers require approximately half the biomass fuel used by traditional smoke driers. -6- also used in the agricultural sector for freight transport and crop harvesting equipment. 2.4 Transport Sectort The transportation sector, which consumes petroleum fuels exclusively, accounts for about 12 mtoo or approximately 212 of total energy consumption. Of the total fuel consumption in the transport sector, ADO accounts for 602, gasoline for 342, aviation fuel for 42 and lubrication oils for 22. Energy consumption in the transport sector is estimated to have increased by approximately 702 since 19J3. 2.5 Commercial and Industrial Sector: The commercial sector is estimated to have consumed 2.3 mtoe in 1989, primarily in the form of petroleum products and electricity. Energy consumption in the industrial sector is estimated at 1.4 mtoe. The combined energy consumption of the commercial and industrial sector represent less than 72 of the total national energy consumption, an increase from the approximately 22 of total national energy consumption in 1983. The Consumption of Petroleum Products 2.6 Vanuatu imports all of its petroleum product requirements consisting of aviation gasoline (Av Gas), gasoline, kerosene, automotive diesel oil (ADO) and LPG for internal consumption and jet fuel for re-export to international airlines. Until 1986, industrial diesel oil (IDO) was also imported for re- export to a foreign-owned, Santo-based, fishing company (South Pacific Fishing Company) which has, since then, ceased its operations. As indicated in Table 2.1, between 1985 and 1990 the demand for aviation gasoline and ADO increased by almost 502 on account of increased power generation and transport sector activities. During the same period the demand for gasoline and LPG has remained static, possibly due to high prices of these commodities.

Of the ADO lmports, about 56Z is used in transport, 402 for power generation and 62 in mechanized agriculture and industrial steam-raising. LPG is used in restaurants and affluent households in the cities of Port Vila and Luganville. Table 2.2 indicates the approximate sectoral consumption on the basis of 1989 imports.

These developments will lead to increased demand for petroleum products (Table 2.3). &/ By mid-1992, the airport was in operation. -8- Table 2.3: PETROLEUM PRODUCTS DEMAND PROJECTIONS 1991 1995 2000 ---------('000 toe)--- AV Gas. 1.21 1.21 1.28 Gasoline 5.38 5.83 6.43 Kerosene 1.03 1.11 1.23 ADO 19.59 23.81 30.38 LPG .30 1.41 1.56 Jet Fuel 5.16 5.80 6.73 Total 33.58 39.17 47.61 Source: Mission Estimates. 2.9 These estimates are based on the assumptions that (a) the demand for ADO for the transport sector will grow at an average rate of 52 per annum over the next ten years, (b) the demand for gasoline, LPG, AV Gas and kerosene will follow the anticipated GDP growth rate of 2-2.25S, and (c) the demand for jet fuel will grow at an average rate of 32 per annum. The Consumption of Electricity 2.10 Electricity is used primarily as a source of lighting and small appliances in the middle-income households and for lighting, cooking, air conditioning and small and large appliances in the high-income households. Household electricity consumption ic limited to urban areas and consequently accounts for only a small part of the total consumptiont Commercial consumers, particularly the hotels and tourist resorts, (and Government offices] are major electricity consumers in Vanuatu (Table 2.4). Given the present relatively high cost of electricity, there is only limited potential for the growth of electricity consumption in the household sector outside the main urban areas. -9- Table 2.4: PATTERN OF ELECTRICITY CONSUMPTION Category Consumption in 1989/90 /a MWh%- total Low Voltage Domestic 1,050 4 Other Small Users 7,280 28 Industry 5,280 21 Public Light 260 1 High VoltsRe 11,950 46 Total 26,000 100 Source: UNELCO t=a) Based on UNELCO data for Port Vila and Luganville which has been adjusted to include small rural-based supply systems. 2.11 Electricity sales in Port 'ila, the biggest load center in Vanuatu, have increased from 14,727 GWh in 1982/83 to 22,220 MWh in 1989/90, i.e., an average annual growth rate of about 6Z5/. However, the growth rate has been uneven in the past with negative growth being registered in 1985/86 and 1986/87, followed by over 20% growth in 1987/88 which, however, declined to 6.7Z in 1988/89 but recovered to 12.1X in 1989/90 (Annex 2.2). The erratic growth of electricity consumption in the past is largely due to the impact of the high voltage consumers (mostly hotels and commercial establishments) who account for about half of the total consumption in Port Vila and whose offtake of electricity is governed by external factors, primarily tourism. 2.12 In the other major load center of Luganville, there has been virtually no significant growth in electricity consumption since 1982/83 and the total sales have stagnated in the range of 2,000 to 2,500 MWh. The annual variations reflect the actual offtake of the two largest consumers - a saw mill and an Abattoir whose combined load (about 560 kW) almost equals the system maximum demand (about 600 kW). 2.13 In other areas, mostly rural in character, the consumption of electricity is insignificant compared with that of either Luganville or Port Vila. The population is very widely dispersed, the population of each village is mostly less than a hundred, and there are no sizable population centers. Therefore, establishment of island-wide power systems is not appropriate and 5/ The statistics available from UNELCO, which accounts for virtually the entire electricity consumption, are based on years beginning 1 October and ending 30 September. -10- small generating facilities are installed at separate demand centers. It is estimated that about 50 small diesel generators of 3.5 to 85 kW in capacity are alres 'v operated by a number of ,overnment agencies for use in government centers .WD owns some rural power seytems in Malakula and Tanna islands, which are operated part time only, for 3 to 12 hours daily (depending on availability of the fuel budget, and the consumer groups connected to the grid) to supply power to government offices and quarters, schools, hospitals, etc. Supply to local communities is limited. Though the operating cost varies considerably depending on the respective costs of diesel, operating load factor, etc., expenditure much exceeds the income based on the usual 25 Vatu/xWh tariff and there is little or no incentive to operate the system efficiently. Equipment is not well maintained and the operating efficiency is low. 2.14 There are also private generating facilities (diesel generators) for coconut processing plants, saw mills, institutions and individuals. Power is used for plant operation, domestic use by staff, churches, communities and others. Electric power is essential for their production p-ocesses, and therefore the condition of generating equipment of private operators is much better than that of government-owned equipment. 2.15 UNELCO's projections indicate that its system peak load in Port Vila will increase from about 5.6 MW in 1991 to about 10 MW by the year 2000, an average annual load growth of 7Z. Its projections for Luganville also assume 71 load growth. UNELCO projects Luganville's peak load to increase from about 0.6 MW in 1991 to about 1.1 MW by 2000. While UNELCO's load projections for Port Vila appear to be realistic, there is less certainty about the projected Luganville demand growth unless the planned industrial estate takes off and the distribution system is extended to the nearby rural communities. Vanuatu's electricity consumption is forecast to increase from about 28 GWh in 1991 to 50 GWh in 2000 (Annex 2.3), primarily in Port Vila as there is little incentive for UNELCO to extend service to peri-urban communities. The Consumotion of Biomass Fuels 2.16 Domestic Cookina: Total consumption of biomass fuels in 1989 is estimated at 40 mtoe. Of this total, fuelwood comprises 701 while agricultural residues, primarily coconut husks and shell, make up the remainder. Fuelwood continues to be the primary source of fuel for cooking in both the rural and urban low-income households of Vanuatu. There have been no accurate estimates or surveys of household energy consumption in Vanuatu. However, assuming an average annual domestic consumption of 500 kg/capita/annum results in approximately 73,000 tons of fuelwood consumption per annum or 25 mtoe/yr nationally. In addition, some small amounts of coconut husk and shells are used as cooking fuels primarily by rural households. tn most cases, these "agricultural residues" account for less than 5 of the total biomass fuel consumption in the household sector. 2.17 Crop Drving: Energy is used extensively for crop drying especially on the large estates producing copra, cocoa and coffee. Copra exports in 1989 amounted to about 25,000 tons while that for cocoa was about 1,500 tons. Copra is dried in Vanuatu primarily by two methods. The traditional method has been by open-fire "smoke driers" which consumes approximately 2.5 tons of husk and shells per ton of dried copra. Until the early 1980s, the smoke- -11- drier method was the predominant means of copra drying in Vanuatu. This method leads to an inferior quality product which contributed to depressed prices for Vanuatu copra and a significant decline in copra production (Table 2.5). Since 1981, there has been an active government program in Vanuatu to convert the majority of copra drying to the more efficient method using "hot- air driers" which also results in a higher quality copra. The hot-air driers require between 1.0 and 1.25 tons of fuelvood or husk and shells per ton of dried copra. By 1989 it is estimated that approximately 652 of Vanuatu's copra production was dried by hot-air driers. Due to the better performance of hot-air driers with fuelwood, copra factory managers indicate that approximately half of their biomass fuel requirements were met with fuelwood while the other half was made up of waste husks and shells. As a result, about 3 mtoe of fuelwood is estimated to be used for copra drying especially by the larger estates in Vanuatu. The remaining fuel is provided by waste husks and shells which amount to approximately 11 mtoe. 2.18 Cocoa is the second most important agricultural export of Vanuatu. Cocoa exports have increased from 868 tones in 1981 to 1538 tons in 1989 (see Table 2.5). Cocoa plants are generally inter-cropped with coconut trees on large plantations. Cocoa in Vanuatu is dried using primarily solid fuel burners which force hot air over flat bed driers. It typically requires approximately one ton of biomass fuels to producs one ton of dried cocoa6/. Most cocoa driers are fueled with a combination of fuelwood as well as coconut husks and shells. No specific data exists on the exact use of these fuels in Vanuatu. Based on interviews conducted by the mission, it was estimated that approximately 20% of the total energy used for cocoa drying was obtained from fuelwood. Thus the total biomass energy used for cocoa drying was estimated at 0.52 mtoe of which 0.10 mtoo consisted of fuelwood.

The tourism and transport sectors are likely to be the driving forces behind the increase. On the other hand, the trend of declining biomass use in agriculture (particularly In the export crop production of copra and cocoa) will reduce the share of biomass in overall energy consumption, as domestic fuelvood use can be expected to increase only slowlys gradual penetration of other cooking fuels may hold the rate of increase of fuelvood use slightly below the pcpulation growth rate. On balance, Vanuatu will experience a shift to greater reliance on commercial fuels. Given the high cost implications of this trend, it will be necessary to explore all possibilities of more efficient use of alternative energy sources such as agroindustrial biomass use and solar energy in appropriate areas of the country. -13- III. ENERGY SUPPLY Petroleum Procurement and Distr4bution 3.1 All petroleum products are Imported and marketed by four interna- tional companies namely, Shell, BP, Mobil and Boral, who obtain the supplies from Australia and Singapore. The import and marketing of LPG is handled entirely by Boral which does not deal with any other petroleum product. The products are imported through the two major ports of Port Vila (Efate Island) and Luganville (Santo Island) with Port Vila receiving about 702 of the total. Port Vila cannot receive medium range vessels (MRVs)2/ due to harbor limitations8/ and Luganville, although possessing adequate harbor capability for receiving MRVs, lacks sufficient demandt/ for MRV-size cargo. Therefore both the ports receive the supplies through local coastal tankersl2/ (LCTs) via Suva (Fiji) and Noumea involving payment of entrepot fees; together with the longer routing, this results in an increase of 3-6 Vt/liter in CIF costs. 3.2 The companies have adequate storage facilities (covering over 3 months' demand) in Port Vila and Luganville. The facilities for ground fuel storage in Port Vila are owned by Mobil and BP with Shell sharing Mobil's facilities. Those in Luganville are owned by Shell and shared with Mobil. LPG storage facilities and terminals at Port Vila and Luganville are owned and operated by Boral; LPG is bottled at the terminals. The storage facilities for aviation fuel in Port Vila and Luganville are owned by BP which shares its Port Vila facility with Shell. The Government has its own storage (for gasoline and ADO) at Port Vila, Luganville, Lakatoro (Malakula Island) and Ieangel (Tanna Island). The marketing companies have no storage facilities in islands other than Efate and Santo. 3.3 Gasoline, diesel and kerosene are retailed in Port Vila and Luganville through the service stations owned by Shell, BP and Mobil and through other locally owned outlets. Other localities in Efate and Santo and the outer islands are supplied by local dealers who transport the products in 200 liter steel drums. The return shipment of empty drums is a major problem as the transporters do not find sufficient profit in such cargoes. Sale of aviation fuels in Port Vila, including re-exportll/, is handled by BP and 2/ Minimum 20,000 ton capacity. 8/ Although the harbor itself is 30 meters deep, its approach channel is shallow. 9/ Since the cessation, in 1986, of Santo-based South Pacific Shipping Company. 10/ Up to 2,000 ton capacity.

Retailing of LPG is managed by Boral or by Speed-s-Gas, a subsidiary of Boral. 3.4 Large consumers such as UNELCO are supplied on the basis of negotiated bulk supply contracts. The petroleum products for the Government's own use (171 of the total imports) are procured on the basis of international competitive bidding.12/ This tendering process and subsequent contracting has steadily improved with the assistance of the Pacific Energy Development Program resulting in increased competition and reduced landed costs. An issue of high distribution margins remains however (para. 4.14). Power Subsector 3.5 The public electric power supply in Vanuatu is entirely based on ADO and is operated at 50 Hz. It is dominated by UNELCO's two urban-based systems. At present UNELCO's power systems cover Port Vila on Efate Island, the capital and the biggest load center, and Luganville on Santo Ieland, the second largest urban center in the country. In other areas there are about 100 small and isolated diesel-based supply svstems. UNELCO operates a diesel power station in Port Vila with a total installed generating capacity of 8,540 kW (Annex 3.1). Port Vila's system peak load in January 1991 va -,640 kW. Its distribution system comprises about 70 km of 5.5 kV primary L. to and about 130 km of 380/220 V secondary lines. By the end of December, 1990, UNELCO had about 3,000 consumers connected to its Port Vila system with a total connected load of 17,256 kVA. Of the 3,000 consumers, Domestic category accounted for about 331 of connections, other low voltage users for 521, Industrial for 132, and High Voltage consumers and Public Lights, 12. During the period 1989/90, UNELCO generated 22,976 MWh and its sales to the ultimate consumers was 22,220 MWh. The system losses including station use accounted for about 61 of the total generation. 3.6 In Luganville, UNELCO has a diesel power station with a total installed generating capacity of 1,080 kW (Annex 3.2)13/ with an annual peak load of 630 kW in 1990. Its distribution system in Luganville comprises 17.8 km of 5.5 kV primary lines and 18.7 km of 380/220 V secondary lines. By the end of December 1990 there were 578 consumers connected to the utility - 274 Small Domestic (481), 164 Other Low Voltage Users (281), 133 Commercial (232) and 7 High Voltage (1S). UNELCO has reported a total generation of 2,507 MWh during the period July 1989 through June 1990 and corresponding sales of 2,421 MWh. The system losses inclusive of the station use on the basis of these figures work out to only 3.43S. Such a low loss figure is attributed to, besides possible metering errors, the fact that the high voltage consrmers, particularly the saw mill and the abattoir, account for the bulk of Luganville sales. In addition, as stated earlier, there are about 100 small diesel generators in isolated rural areas with unit ratings ranging from 12/ Mobil holds the current contract awarded for a two year period expiring July 4, 1991. It is based on 502 spot and 501 posted price at Singapore. 13/ By mid-1992, the capacity had increased to 2,000 kW. -15- 3 to 100 kVA. Their total capacity is, however, insignificant compared with that of UNELCO. The units are 15 to 30 years old and are in very poor condition with very low operational efficiency and reliability due to insufficient and infrequent maintenance. In addition, because of their isolated location, the ADO supplies provided to these generators, which are not always available when needed, carry a high transport premium. Future Power System Eg2ansion 3.7 The near-term system expansion program of UNELCO envisages retiring the old diesel units in Luganville which were installed in the 1960s and replacing them with a 1,000 kVA diesel unit by July 1991.141 As a longer- term proposition UNELCO has also applied to GOV for the right to develop the Sarakata small hydropower project near Luganville (about 1 MW). Once the hydropower project is commissioned UNELCO proposes to keep the diesel plant as an emergency standby. GOV is, yet to respond to UNELCO's application. For meeting the projected increase in load in the medium term in Port Vila, UNELCO is planning to add a diesel unit with a rated capacity of 2,170 kW in 1992 at an estimated cost of $2 million. To meet the projected load growth on Efate in the 1990s, there are, besides the diesel, alternative generation options - hydropower in the medium-term, and geothermal in the longer-term. These, however, need to be studied further to establish their technical feasibility and economic viability. 3.8 The small hydroiower potential in Vanuatu can be classified into two categories, namely (i) the relatively large-scale ones for supply to the urban power systems of Port Vila and Luganville, and (ii) the minor ones for rural supply in remote areas. Two hydropower projects, the Teouma river Droiect on Efate for Port Vila, and the Sarakata river proiect on Santo for Luganville belong to the former category (Annex 3.3). The development scale envisaged in the past studies is 1,200 kW for the Teouma project and 600 to 6,400 kW depending on the prospective utilization of the available head and discharge for the Sarakata project. 3.9 Based on the findings of the mission's site visit, the Sarakata project appears more likely to be economically attractive than the Teouma project in view of the larger available discharge, easier access, shorter waterway for the same head, and greater ease of installation of the waterway, factors which contribute to cheaper constructl-A costs. Both projects are situated on limestone blocks and therefore need a thorough geological investigation before their costs can be realistically estimated. 3.10 The results of past prefeasibility studies indicate that the economic feasibility of the Teouma project is marginal and may only become viable at much higher oil prices. From similar studies, the Sarakata project appears to be far more promising, particularly if it is developed for a minimum 1,000 - 1,200 kW capacity. The latter would be justified only if the 141 By mid-1992, UNELCO had not replaced the old diesel units, but had added a 920 kW diesel unit. -16- demand in Luganville exceeds the 800 to 1000 kW level. In this context, it has been proposed to interconnect the Luganville system with nearby Malakula island. The interconnection with Malakula is not likely to be economically viable as the distance to Norsup, the largest load center, is 70 km from Luganville, including a 15 km submarine section, while its maximum demand is only about 100 kW. 3.11 Recently, the Japan International Cooperation Agency (JICA) has agreed to carry out a detailed feasibility study of the Sarakata project, scheduled to begin in 1991. GOV proposes to respond to UNELCO's application for development of the project after the results of the JICA study become available. If the JICA study indicates that the project is viable, GOV would consider its implementation, possibly by a joint development company (HPD). Implementation of this project should only start if it becomes clear that Luganville demand will resume growth beyond 1 MW maximum demand. Until then, the new diesel plant will provide adequate generating capacity. 3.12 The current demand for electricity in the individual rural centers, which are widely dispersed, is very small, rarely exceeding 20 kW. This makes even micro-scale hydro developments uneconomic in most cases. However, the Brenwe/Unmet hydropower project on Malakula Island, could be an exception (Annex 3.4). Further detailed studies should be carried out to establish its viability compared with other options such as small diesel or copra processing-based co-generation for meeting the combined demands of Norsup arLd Lakatoro towns, the most important regional centers after Luganville. 3.13 Preliminary investigations carried out by the Department of Geology and Mines indicate that there could be significant potential for electricity generation from aeothermal enerRV on Efate Island. However, further investigations to establish the technical and economic viability of this potential resource need to be carried out before any investment decisions can be taken. An initiative of the Department of Geology and Mines to conduct exploration drilling for the final phase of the resource assessment on Efate is in progress. It is recommended that two exploration bore holes of depths between 1,000 to 1,500 feet be drilled, and that GOV seek either private financing or the assistance of multi-lateral institutions to finance the related exploration costs estimated at about US$4 million. Care should be exercised to ascertain first whether significant private interest in geothermal exploration and development can be mobilized, given the modest demand levels in Efate. 3.14 Wind-based xeneration might also prove to be a viable option in the longer term. At present, there is not much data on the potential for wind energy in Vanuatu. Stand-alone wind generators for isolated rural areas are unlikely to be cost effective. However, grid connected systems in the Port Vila and the Luganville areas, if viable wind regimes exist, could eventually provide opportunities for partial displacement of diesel-based generation. For the isolated rural centers, decentralized systems based on solar energy or agroindustrial cogeneration using bioma3s should be compared to the ADO-based electricity supply (paras. 3.17-3.23). -17- Biomass Potential 3.15 Fuelwood: The primary source of fuelwood in Vanuatu is from the natural forests. There are some estimated 900,000 ha or 75X of the nation's land area under natural vegetation.15/ Preliminary surveys of the natural forests indicate between 15-25 m'/ha of useful timber but do not provide any estimate of total volume of wood per hectare. Assuming a net annual growth of 10 m'/ha/yr in Vanuatu translates to approximately 9 million m3/yr of wood. This is equivalent t approximately 6.3 million tons of wood/yr or over 80 times the current estimated annual consumption of fuelwood' in Vanuatu. Assuming that only 10% of annual forestry growth is available for fuelwood, consumption still results in a total supply of approximately 214 mtoe/yr. Thus, there does not appear to be an immediate shortage of fuelvood in Vanuatu, especially in the rural areas. In the urban centers of Port Vila and Luganville, where 18Z of Vanuatu's population is located, fuelwood is beginning to appear in the marketplace, possibly as an indication of the onset of diminishing freely available supply sources in the vicinity of these urban centers. Data on forest inventories and, in particular, urban fuelvood supply sources, is not available, making difficult any projections of future prospects for urban fuelwood supply. 3.16 Biomass Residues. While the bulk of biomass supply (more than 200 mtoe per year) comes from net growth of fuelvood, several sources of forestry and plantation residues add to the available biomass (Annex 3.5). Sawmill and logging residues amount to about 12 mtoe, priming and thinning yields from forestry plantations provide about 0.5 mtoe, and coconut residues and senile stemwood yield about 87 mtoe. The total potential supply of biomass for energy purposes, therefore, is more than 300 mtoe per year, compared to current annual consumption of about 40 mtoe. No general biomass supply constraint is evident. Biomass Gasification 3.17 A successful small-scale biomass gasificatlon projects is located at Onesua High School in north Efate. The systam is a 15 kWe modified "BECE" power gasifier fueled by wood obtained from local Eucalyptus plantations. Labor for the system is provided by the students of the school. The system was installed in December 1986 under the EEC funded Lome II energy program. During the plant's first year of operation it was reported to have saved approximately US$7,000 in diesel fuel costs, equivalent to about 10% of the school's total annual operating budget. By the end of the second year the plant had logged over 5,000 hours of operation producing 57,000 kWh of electricity from 123.5 tons of dried fuel (or equivalent to 2.17 kg/kWh). This represented an average utilization factor of 29Z and average load of 11.4 KW. 3.18 The economics of a typical potential biomass gasifier system for Vanuatu is presented in Annex 3.5. The analysis indicates that the 25 kWe biomass gasifier system, if manufactured locally in Vanuatu, could conceivably 15/ Source: "Republic of Vanuatu - Second Development Plan:1987-1991" -18- be financially and economically competitive with a diesel electric generating system under the right circumstances. At present a 25 kWe diesel generator produces electricity at financial cost of approximately 75 Jt/kWh and an economic cost of 60 Vt/kwh. The imported gasifier system results in financial and economic coats of electricity of 89 Vt/kWh and 83 Vt/kWh respectively. If manufactured locally, the total capital cost of the gasifier could perhaps decline to the diesel level. If the diesel price rises above 130 Vt/l, even the higher cost imported biomass gasifier may become competitive. 3.19 Even with the relative success of the biomass gasifier project at Onesua, careful evaluation of the necessary organizational and institutional requirements to support successful gasifier projects like that at Onesua must be carried out prior to a commitment for wider scale dissemination.16/ Many biomass gasifier projects have been attempted in the Pacific and elsewhere and have failed because of a lacl of the necessary considerable organizational and institutional support. The relative success of the Onesua project can be traced to a dedicated and well trained technician and above normal technical support for the project as it was carried out under a grant demonstration program. Biomass Co-generation 3.20 The abundant availability in Vanuatu of potential biomass fuels, primarily wood and coconut husks, shells and stemwood, as well as the need for process heat for copra drying, could present the opportunity for biomass co- generation systems especially at large-scale copra estates located near a medium sized urban centers that are presently provided electricity through diesel generation. One such possibility exists on Malakula Island near Lakatoro. At present, Lakatoro is serviced by a 70 kVa diesel generator which operates approximately 12 to 14 hours a day. Energy supply in the area is severely limited by the small size of the Lakatoro diesel plant. In addition, small diesel generators are used to supply a local school, hospital and the staff of the nearby large copra estate. Potential demand for electricity In the Lakatoro area is estimated to be approximately 1 MWe. At present, diesel generation is the _aly alternative being considered. Opportunities for small hydro have been identified on Malakula but have not been adequately assessed to date to determine technical and economic viability. Given the availability of biomass fuels in the vicinity of the Lakatoro area and tht. need for process heat for copra and cocoa drying at the large estate, the pcseibility for a biomass co-generation system should be considered seriously. A proposal by the cop a estate exists that offers to supply the community together with its own needs for drying, currently met by the use of residue from copra production. The supply price to be proposed by the estate should be compared to the cost of supply from expanded diesel generation and the proposed mini- hydro plant. 16/ By mid-1992, the Government had plans to provide gasifiers to several schools. -19- Solar Enemy 3.21 Solar energy represents the largest potential source of energy in Vanuatu. The annual average solar insolation in Vanuatu ranges from 2,000 to 2,300 hours at an average intensity factor of 6 Kwh/en/d. A 10 conversion efficie.-y of solar energy to electricity results in ax. equivalent of approximately 535 toe/ha/yr which is over 10 times more than the biomass energy equivalent produced by a managed plantation yielding 20 mS/ha/yr. 3.22 The heat from direct solar energy is presently utilized to a certain extent in Vanuatu. The most predominant use of solar energy is for some copra and cocoa drying, primarily by small-holders. Another increasing use of direct solar energy in Vanuatu is for hot water heating primarily by high- income households both in the urban and rural areas. The alternative for hot- water heating in these homes is either electricity or LPG. At current costs for electricity and LPG, solar hot-water heaters are more cost effective and as a result have been widely adopted in the domestic sector. Opportunities for use of solar hot-water heating still exist in the commercial sector, especially for hotels and hospitals, where they can be used in conjunction with conventional water heating systems to reduce overall energy costs. The potential for photovoltaic electricity is not yet large, as comparative costs are high (Annex 3.5). However, at high delivered kerosene and diesel prices in remote areas, PV lanterns can become competitive above Vt 80/1 diesel. PV systems alsoc depend on the availability of spare parts such as controllers, batteries, etc., and their reliability may not be better than diesel supply or kerosene lighting if this is a problem.17/ 3.23 It appears that biomass-based and solar energy supply could be competitive under certain circumstances in areas where petroleum product supply is difficult or expensive. Where gasifier options are considered, a careful evaluation of the sustainability in institutional terms is required. Biomass cogeneration or PV community supply systems should be tested for their attractiveness for private investors. 17/ By mid-1992, the Government had received assistance from several organizations to speed the dissemination of PV lighting in rural areas, targeted at schools, clinics and other institutions. -20- IV. POLICY ISSUES Environmental Isgues 4.1 The limited extent of energy sector devel3pment to date has resulted in some improvements in the living environment while not producing significant detrimental environmental impacts. Nevertheless, the expansion of development activities and the fast growth of the country's population meanas that energy related environmental problems are a real future prospect. unless energy development is placed on a sound basis of environmental sasessment and planning. 4.2 GOV has a policy for protection of the environment, and a certain amount of legislative power in this respect. Institutional provision has been made through a Department of Physical Planning and Environment which, among other things, has oversight of environmental assessment (mostly in the form of environmental imnact assessment) of development activities. It is also the lead agency in the preparation of a national conservation strategy. Particular emphasis is liven in GOV policy to protection of the marine environment, from which are taken the seafoods which constitute an important component of ni-Vanuatu diet. 4.3 one aspect of the social environment is of special importance in Vanuatu -customary ownership and use rights in areas subject to development projects. GOV efforts to make legal provision for an appropriate measure of benefits for landholding groups which make customary land and sea areas available for energy sector activities will be essential for the orderly development of the sector. 4.4 Petroleum Products and the Environments The siting of Vila's petroleum storage is a matter of considerable local concern, not least because of the hazard which it poses for nearby residents. The storage facility predates recent squatter settlement and resolution of the problem lies in firm and effective town planning decisions. The prospect of marine pollution arising in the course of incidents involving tankers in Vanuatu waters, and with ship-to-shore transfers, is a matter which requires preemptive planning. Particular care is needed in the handling of imported petroleum products so as to minimize harm to the environment in the event of spillages. Some precautions are being taken by the companies concerned. This is not, however, backed by the legislation and environmental protection equipment needed to deal with spills. If GOV's marine protection objectives are to be met, such legislation should require oil companies to have oil spill contingency plans, equipment to deal with spills and staff trained to deal with such circumstances. The marine environment of proposed alternative sites for petroleum product storage is characterized by clear, unpolluted water, corals and seagrasses. These sites are well protected and any spills would not quickly disperse. 2' new storage facility should be subject to full environmental assessment. -21- 4.5 Electricitv Production: Diesel generating sets currently in operation in Vanuatu generate a measure of air, water and noise pollution. The resulting impacts are at present minimal. Even so, it is important that GOV firmly establish good environmental practice in and about diesel generating plant and uo preempt the possibility of later problems. The general environmental circumstances of two priority hydro prospects were considered. Preliminary inspectLon suggests that slnce the catchment of the Sarakata (Santo) site carries forest cover whLch has been subjected to consLderable dlsturbance through shiftlng cu!tlvation, lts natural values for conservatlon have probably been substantially reduced. The sLte at Teouma (Efate) is apparently much less disturbed. Both streams would experlence reduced flows Ln streambeds between intake structures and the point at which water would re-enter the natural system downstream. In line wlth Gov policy these and other envLronmental changes would requlre envlronmental assessment before implementatlon is considered. 4.6 Biomass and the Envlronments Fuelwood is extensively used by both rural and urban households. This le mostly obtalned by collectlng wood from secondary forest, partlcularly old food garden areas. Some areas are now experienclng shortages. To ensure continued availabLlity of fuelwood supplles in future, lt would be advlsable to encourage smallholder woodlots. EnvLronmental consequences of not dolng this could be depletion of bLodiversity ln pockets of remalning natural vegetatlon and Lncreased soil eroslon and landelLps on steep land from which vegetatlon ie removed. Thie could adversely affect other sectors such as agriculture and fisheries. Industrial scale biomass energy development schemes should be undertaken in close consultation with agriculture, forestry and environment agencles, and fully assessed in envlronmental terms.ijf/ 4.7 Conclusions: There ls limlted provlslon for dealing wlth the envLronmental aspects of energy development ln Vanuatu. These have not been seriously addressed in the varlous reports on proposed energy projects, nor does GOv yet have adequate capabllity in envlronmental assessment, or the adminLstration of any new legislatlon. 4 Through the South Paciflc RegLonal Environment Programme, there are growing opportunities to obtain the type of assistance requlred. The measures needed for addressing environmental matters in energy sector development include: (a) Enact environmental assessment and planning legislation; (b) Prepare a national oll spill contingency plan backed by legLslatLon. tralned personnel and pollution control equipment; J_8/ Guidance is provided by PEDP Reports REG 84-10: Guidelines for Lange Scale Fuelwood Plantations in the Pacific islands and REG 89-2s guidelines for Environmental Assessment of Energy Projects in Small island Countries. 19/ By mld-1992, the Government had taken some measures to reduce the lead content of motor spirit. -22- (c) Strengthen the capacity of Energy Unit staff to contrib-ate to national development objectives by providing tralning which would fit them to better understand the environmental and social dimensions of their work; (d) Address and act on the possible public health hazards associated with tne energy sector, currently concerning disposal of lead and alkaline batteries; (e) Utilize opportunities available through the South Pacific Regional Environment Programme for advice, training and other assistance regarding environmental aspects of the energy sector; (f) Customary land tenure and rights to be sensitively considered and rights-holders given maximum opportunities for participation in assessments and monitoring; (g) "Development benefit packages" for those groups and individuals who have valid customary rights in the area of a project; (h) More far reaching analysis of the implications of energy pricing on natural resource use and the environment; and (i) Provision for management of hydropower catchments with a view to maintenance of water quantity and quality and protection of biodiversity. Enerav Pricing Issues 4.8 Power Tariffs and Utility Finance: UNELCO's tariffs, which are now uniformly applicable in both Port Vila and Luganville are based on the relevant provisions of the Concession Agreement. The tariffs applicable for the fourth quarter of 1990 are summarized in Table 4.1. -23- Table 4.1: UNELCO'S TARIFFS FOR FOURTH QUARTER OF 1990 BASIC PRICE P a VATU 29.60 Logw Voltaae - Domestic Rt Charos Standing charge per kVA nil nil 1st rate s 0 to 60 kWH 0.65 p 19.24 Vt/kWh 2nd rate : 61 to 120 kWh 1.00 P 29.60 Vt/kWh 3rd rate : 121 kWh & above 1.7C P 50.32 Vt/kWn Low Voltaae - Other UVes Standing chars3 per kVA 19 P 562.40 Vt/kVA kWh price 1.00 p 29.60 Vt/kWh LoW Voltaae - Busineges Standing charge per kVA 20 P 592 Vt/kVA kWh price 0.90 p 26.64 Vt/kWh Low Voltaae - Public Liahtina Standing charge per kVA nil nil kWh price 0.80 P 23.68 Vt/kWh lich Y_ltaa2 Standing charge per kVA 25 P 740 Vt/kVA kWh price 0.67 P 19.832 Vt/kWh Note: The above charges are based on an average power factor of 0.801. Should the power factor drop below 0.801, the base price of electricity is increased by one per cent per hundredth of the average power factor below 0.801. There is, however, no corresponding decrease in the base price if the consumer maintains higher-than-the stipulated power factor. Source: UNELCO 4.9 All consumers are required to contribute to UNELCO's service connection coast. Such consumer contribution for the low voltage consumers is 70% of the costs if the length involved is 300 meters or less and 90% if it exceeds 300 meters. High voltage consumers are, however, required to pay 90% of the costs of system extension, 50% before the start of the works and the balance before the supply is effected. 4.10 UNELCO's tariffs are adjusted every quarter based on a complex formula as provided under the concession. 2/ Essentially the adjustments allow for variations in the followings 2&/ By mid-1992, the Government had started a study aimed at revising the tariff calculation mechanism. -24- (a) average overall wholesale price index published by the INSEE (French National Institute of Statistics and Economic Studies); (b) average price of diesel oil ex-wharf Port Vila as per the last two delivery invoices received by UNELCO in the first three months of the six-month period preceding the adjustment period; (c) amount of fees and excise taxes payable by UNELCOI (d) number of kWh sold in the first twelve months of the fifteen-month period preceding the adjustment; and (e) average daily wage earned by an unmarried laborer during the first three months of the six-month period preceding the adjustment. 4.11 Given the small market and the generally high costs prevailing in the other sectors of the economy in Vanuatu, electricity prices can be expected to be higher than ,lsewhere. On the other hand, UNELCO's technical operations are being conducted efficiently and economically, and the system energy loss and staffing levels are well within the industry standards. Nevertheless, UNELCO's tariffs are generally perceived to be higher than they need be even after allowing for a reasonable return on investments. Also, there appears to be no rationale for adopting French indexes for adjusting the power tariffs in Vanuatu. Since no detailed cost data are publicly available, it is not possible to quantify the actual costs and estimate appropriate tariff levels. In this connection it should, however, be noted that UNELCO is self-supporting and is able to generate adequate revenues internally or from commercial borrowing to finance all its system improveMant and expansion projects. As the pricing formula is essentially a cost-plus one, there are no strong incentives for UNELCO to reduce costs, such as by minimizing their fuel pr!ce, or cutting labor cost. 4.12 In the context of attempting to reduce UNELCO's generation costs, the possibility of switch-over from ADO to Heavy diesel oil as fuel for generation from the larger-size units (1,000 kW and more) has been reviewed. However, such a fuel conversion is not expected to be cost-effective since the additional costs of handling and storage of another petroleum product (currently heavy diesel oil is not being imported by Vat.uatu) and the equipment conversion costs will far outweigh the possible savings in the fuel costs, particularly in view of the limited quantities involved. 4.13 Petroleum Product Prices: The Government abolished price control in May 1989.j1_J Since then the marketing companies and retailers have been free to set the prices. The cost structure of gasoline, ADO, kerosene and LPG as on Sept. 1986 and Sept. 1990 (before the recent Gulf War crisis) is given in Table 4.2. LI/ By mid-1992, the Government had formulated plans to exert some controls on petroleum prices. -25- Table 4.2t PETROLEUM PRODUCTS COST STRUCTURE Gasoline ADO Kerosene LPO Sept 86 Sept 90 Sept 86 Sept 90 Sept 86 Sept 90 Sept 86 Sept 90 - - ---- t - --- -Vt/Kg- crF 22.60 25.90 18.2 26.02 18.95 26.57 Na 52.36 Duty 12.00 32.00 7.00 12.00 2.00 8.00 17.00 17.00 service Tax 5.00 5.00 5.00 5.00 5.00 5.00 5.00 5.00 Wholesale Price 47.13 80.50 41.42 61.50 36.30 65.50 Na Na Retail Price jA 55.13 87.70 47.42 67.00 41.30 70.40 122.00 164.00 La In major towns only. Sourcet Ministry of Trade, Commerce, Cooperatives, Industry and Energy. 4.14 While the CIF prices, during the period Sept. 1986-Sept. 1990. for gasoline, ADO and kerosene increased by 15%, 42% and 40% respectively, the wholesale prices increased by 60%. 48% and 80%. During the same period. wholesale margins (wholesale price less import duty, service tax and CIF price) for gasoline, ADO and kerosene increased by 135%, 66% and 150% respectively. It is likely that this can be attributed to the limited compatition due to the small and remote market. 4.15 Two other factors are also contributing to high prices: (a) The approach channel to Port Vila harbor (receiving about 70% of the total petroleum product imports) is not deep enough to allow medium range vessels (20,000 tons capacity) to carry the frelght directly from the supply ports. Evea the local coastal tankers (2000 ton capacity) can negotlate the approach channel only with a maximum of 900 tons of cargo. The products are therefore brought in only partlally (40%) loaded local coastal tankers from Suva and Noumea involving additional expenditure in the form of entrepot fees and additional mileage, lncreasing the freight cost by 3-6 Vt/liter. (b) steel drums are used for the transportation of products from wholesalers' depots in Port Vila and Luganville to retailers on outer islands. This mode of transportation involves about 15% loss of product and about 20% loss of empty drums, resulting in an increase of about Vt 20/liter in the cost of the product. -26- 4.16 A combination of several measures involving (i) improvements in infrastructure, (ii) increased competition, and (iii) enhanced monitoring of coperations is required to control the escalation of petroleum product costs. Port Vila storage facllities should be made available to medium range vessels (MRVs). since about two thirds of the country's product imports are recoLved at Port Vila, an additional freight cost of about Vt 80-100 million per year is being incurred. The Government has two options of making the storage accessible to MRVa: (i) construction of a pipeline from the nearby deep harbor to the storage tanks along with an enhancement of the safety measures commensurate with the proximity of the town, or (ii) relocation of the storage tanks to a site that is accessible for NRVe. An early decision will result in considerable savings in recurrent costs. Similarly, distribution costs could be decreased by the use of the "fabridrum", a synthetic rubber bag, an alternative which is being evaluated by PEDP in cooperation with Mobil Oil Fiji. The Government should conduct such trials with technical assistancet if satisfactory, the use of the fabridrum may reduce the losses substantially. 4.17 As the domestic market for petroleum products is small, it is unlikely that any more international oil companies will be attracted to operate there. To introduce further comnetition - with a view to reducing the retail price - the Government should explore the possibility of marketing part of the domestic needs (particularly kerosene) at competitive prices but without subsidies. The required quantities to be imported can be packaged into the usual tender for the import of products for the Government's own use. Preliminary estimates indicate that the cost of additional storage and related facilities may be recoverable in 6-8 years. However, adequate maintenance and management of such additional storage facilities will be necessary, a difficult task in view of the skill shortages of the Government. An alternative may be a resumption of the regulatory dialogue with the oil companies, albeit on a more informal basis than before. For lono-term olannina and cost control, the Government needs to acquire the capability of evaluating and monitoring the costs of procurement, freight, storage, and distribution of products. Initially, a cost analyst should be appointed in the Energy Unit. This will enable the Government to have a productive dialogue with the importers, wholesalers, and distributors in matters of cost control and desirable profit margins. Ingtitutional and Strateav Isgues 4.18 Power Sector Reculationt There is no effective Government regulation, a normal feature in any country. There are neither electricity legislation nor safety standards and codes governing the power subsector though UNELOO voluntarily follows French standards. GOV also lacks adequate staff with the required expertise and experience to effectively regulate the public power supply and safety.21/ The Government mechanism to monitor the power subsector is thus virtually non-axistent. Nevertheless, the Government, presumably with a view to having a greater say in mattars relating to UNELCO's 33/ By mid-1992, the Energy Unit had started a long-term program to acquire more detailed information from UNELCO. -27- operations, has recently acquired 10 per cent equity in UNELCO, financed through commercial borrowings, and even proposes to increase its stake in the utility to 30 per cent. Further, GOV has also recently established Hydro Power Development Limited, a joint venture with UNELCO, for developing the indlgenous hydropower potential. 4.19 In the light of the above, the fLrst priority of GOV should be to acquire the urgently needed expert advice and assistance so that it can effectively use its stake in UNELCO for steering UNELCO's future operations more in the national interests than has been posslble in the past. This is particularly important since the franchise of UNELCO will come up for renewal only in the year 2011. On the whole, the Government's best strategy appears to be a gradual increase in the exercising of its regulatory role within the framework of the franchise agreement vis-a-vis UNELCO. Towards this end the appointment of an Electricity Commissioner as the agreed representative of the regulating government is conaidered an essential and urgent step. The Electricity Commissioner can also assist the government .n the implementation of the various technical assistance projects recommended in Section V. In the above circumstances it is not considered necessary or practical for GOV to introduce special electricity supply legislation at thiL stage. Such legislation could be deferred until UNELCO's concession agreement comes up for renewal in 2011. However, institutional weaknesses of GOV in the power subsector need to be addressed immediately so that it can effectively monitor the operations in the power subseccor role and safeguard the interests of the public within the existing framework. 4.20 Power SuDDly Standards: As stated earlier, Vanuatu does not have any design standards or safety standards and codes. In their absence, UNELCO is adopting the French standards developed by Electricite de France. Adoption of these standards and the technical competence of UNELCO have enabled it to meet the industry standards and provide reliable power supply in its franchise areas. As such the absence of national design standards by itself is not a matter of concern. However, the absence of safety standards and codes needs to be rectified from considerations of public safety. Since the Government lacks the necessary resources - financial and manpower - it is recommended that GOV should seek and obtain foreign technical assistance for developing the relevant standards and codes and for ensuring their compliance. 4.21 Electricity Conservation: Considering the current complete dependence on imported fuel - automotive diesel oil - for power generation. there is a compelling need to promote energy conservation and demand management in this vital subsector. Opportunitieo for energy conservation through use of compact high efficiency fluorescent lamps, better insulation of air-conditioned homes and higher efficiency appliances, need to be actively promoted through information campaigns and through appropriate incentives such as import duty exemptions on energy efficient appliances and equipment. Given the tariff structure (i.e., a cost-plus tariff formula), which for high-energy users includes a substantial charge based on connected load, there ie hardly any incentive for UNELCO to promote these conservation measures. The consumers also do not have any incentive to invest ln power factor correction equipment, one of the most effective means of reducing their demand, since UNELCO's tariff structure is based on connected load and does not reward -28- consumer initiative for improving their power factor above the stipulated 80 per cent level. This leaves only the Government to take the required initiative and devise appropriate incentives. However, GOV lacks the requisite organization and expertise though a UN volunteer has been in Vanuatu for two years. Hence it is recommended that GOV should also seek forelgn technical assistance to develop appropriate measures for demand management and energy conservation and implement them in a cost-effective manner.2/ 4.22 Rural Electricity Supolys The diesel units in the isolated rural areas are very old and inefflcient. Significant improvements in their generation efficiency and reliability as well as reductions in consumption of the imported ADO, which has to be transported to isolated areas at considerable cost, need to be effected. These could be achieved by improving the quality and frequency of maintenance provided for these units. In cases where they are to be replaced, a careful evaluation should be undertaken before action is taken on installing new diesel units to determine if alternative energy sources such as photovoltaic lighting or biomass gasification systems (similar to that at the Onesua High School in north Efate) would be more cost effective. In this context, a careful evaluation of the necessary technical and organizational support for these renewable energy systems must also be undertaken prior to the implementation of these alternatives since without such support these options can not be sustained for any length of time. 4.23 Promotion of Hydrocarbon Exploration. According to the study conducted under the auspices of the South Pacific Geophysics Program (completed in 1988). four sedimentary basins in the waters of Vanuatu (North Aoba, South Aoba, Malakula, and East Santo) could be potential hydrocarbon targets. Since North and South Aoba lie in waters too deep for present day drilling and development capabilities, Malakula and East Santo appear to be the most promising sites for further exploration. Faults, folds and reefal structures in these basins could be potential hydrocarbon reservoirs. As part of the preparation to promote explorationt in Vanuatu. the Government intends to produce a promotional handbook in 1991 and draft petroleum legislation will shortly be put before Parliament. However, additional supporting data, through detailed seismic studies, would still be required to tempt the international oil industry to undertake petroleum exploration in these basins. The Government should therefore seek technical assistance to conduct these studies as soon as possible and present the results in a promotional seminar. fLi By mid-1992. the Government had undertaken some energy audits, and had plans to request assistance from the Forum Secretariat for audits of all Government offices. -29- V. INVESTMENT AND TECHNICAL ASSISTANCE PRIORITIES Power Subsector 5.1 It is unlikely that there will be a need for any significant GOV investment in the power subsector in the medium-term. Even if the technical and economical viability of the Sarakata mini-hydropower project is established by the JICA study, in view of GOV's financial resource constraints it is recommended that the project be implemented by UNELCO or by VHD with UNELCO's resources. There are, however, several areas where the government needs considerable foreign technical assistance. A list of the technical assistance projects which are urgently needed is given below: (a) lnst4tutional Suioort: GOV requires immediate institutional support in the power subsector to enable _t to effectively monitor and regulate UNELCO's operations. Towards this end GOV needs the services of an experienced power utility expert to work as Electricity Commissioner backed by a small functional secretariat. If no full-time qualified person can be found, a part-time solution could be envisaged. The cost of providing these services for an initial period of three years is estimated at about US$500,000; (b) Develooment of Renewable Eneray Resources: Technical assistance is required to study the technical and economic feasibility of (i) diesel replacement programs in the rural areas, where alternatives are economically and institutionally attractive; (ii) the 120 kW Brenwe/Unmet hydropower project and other power supply options in the Norsup/Lakatoro area; and (iii) wind energy-based electricity generation as supplementary power for the Port Vila grid. The cost of this technical assistance is estimated at about $500,000, (c) Safety Standards and Codes: The proposed technical assistance essentially envisages the provision of the services of an expert in electrical safety standards and codes for a 3-month period to develop the standards and codes for Vanuatu. The implementation of the standards and the codes can be handled by the Electrical Commissioner. The cost of the proposed technical assistance is estimated at about $75,000; and (d) Energv Conservation: The proposed technical assistance envisages the provision of the services of an expert in energy conservation for a period of one month to draw up the relevant measures to be adopted by the government. The implementation of these measures can be handled b: the Electrical Commissioner. The cost of the proposed technical assistance is estimated at about $25.000. Petroleum Subsector 5.2 The oil and gas subsector presents several attractive opportunities for development and technical assistance to the Governments -30- (a) Hydrocarbons Exoloration: Detailed seismic studies and their analysis and presentation are needed to complement the ongoing preparation of petroleum legislation and a promotional handbook; (b) Petroleum Product Transport Cost Reduction: The decision to either relocate existing storage facilities to the deeper harbor area, or construct a pipeline from the deeper harbor to the preoent storage location, will have to be based on a detailed cost comparison and environmental evaluation. Some public sector investment may be necessary to provide an incentive for the suppliers to switch to larger tankers. In parallel, trials with fabric containers for local distribution should be conducted; and (c) Enerov Unit Staffina: The Energy Unit of the Ministry of Trade needs to be equipped with a petroleum cost analyst who could be financed through technical assistance. As this position does not necessarily have to be full-time after an initial period, a Pacific Regional solution can be envisaged. New and Renewable Sources of Enerav (NRSE) 5.3 Fuelwood: There is little reliable and accurate information on the supply and consumption of fuelwood in Vanuatu. There is no Government institution that is directly responsible for assuring the continued supply of fuelwood. The Forestry Department is only now beginning to assess the forest resource base. However, very little of this effort is directed at determining the rate of growth of fuelwood supply and regeneration. It is therefore recommended that technical assistance be provided to Vanuatu to: (a) Conduct a comprehensive fuelwood resource assessment that is incorporated within the ongoing Department of Forestry work; (b) Conduct a detailed survey of urban and rural household energy consumption patterns with the emphasis on determining more accurately the levels of consumption of fuelwood and other sources of energy as well as the economic and social parameters that govern household energy decisions; and (c) Create, within the Energy Unit, the capacity to develop and formulate a "household and fuelwood energy strategy" which accounts for Vanuatu's growing urban population, increasing demand on fuelwood and decreasing forestry resource base. 5.4 Other Renewable Enerav Ovtions: To date, only minor efforts have been undertaken to accelerate the economic development of these resources. It is recommended that technical assistance to assess and develop these renewable energy options be provided specifically to: (a) Identify opportunities for the use of biomass waste resources and small-scale blomass casification systems to displace imported petroleum fuels especially in rural agro-industries such as copra processing and for small-scale rural electrification; and -31- (b) Investigate the feasibility of solar PV lanterne an_ sgi_ll vlloAae solar electrification scheme. to displace the present consumption of kerosene and diesel for these purposes. 5.5 A majority of the recommended NRSE technical assistance initLatives should be undertaken withln a carefully coordinated program. At p-esent, the Energy Unlt lacks the manpower to undertake any of these efforts. As such, priority should be given to recruitlng an experienced internatlonal NRSE expert capable of both carrying out a comprehensive evaluation program while tralnlng the Energy Unit's staff. In addition, financial assistan e to carry out the components of the NRSE evaluation should be secured. It is estimated that US$3 millLon cver a three year period is required to assist Vanuatu in developing it. NRSE resources and potential.

Various studies have been performed in the past to identify the hydropower potential in the country, and the two hydropower projects of the Teguma river project for Port Vila and the Sarakata river project for Luganville have been selected as the moot favorable projects. ENEX of New Zealand issued a prefeasibility report for these two projects in July, 1987 and Hangzhou Regional Center for Small hydro Power of China presented a feasibility report for the Teouma river project in December, 1989. These past studies were based on 3 years of data from 1982 to 1984 taken by the ORSTOM center of Noumea, New Caledonia. At present the Department of Geology, Mines and Rural Water Supply is conducting hydrological observations for these two projects. By installing self-recording instruments, they are collecting rainfall data of their respective basins and discharge measurements and stage recordings are performed near the proposed intake sites. A data base for hydrological data has been formulated. 2. The two projects were conceived as run-of-river developments, consisting of diversion and intake structures, sand settling ponds, waterways, regulating ponds, steel penstocks, powerhouses with generating equipment, spillways, transmission lines, etc. In Vanuatu, the monthly rainfall in a year is relatively well distributed; the minimum monthly rainfall is more than the half of the annual average, and relatively heavy rainfall occurs during the hot and wet summer time when there is a high airconditioning load, and is small in the winter season when the electricity demand is less. This fact favors run-of-river hydro development. The Teouma River Proiect is located about 10 km east of the c&pital Port vila and is planned to generate 1,200 kW power by utilizing about a 40 m head of the river. The catchment area at the proposed intake site is 38.5 km and the annual mean flow is 2.42 m3/sec. Due to the porous nature of the catchment geology, the annual flow duration characteristics are relatively flat and the firm flow is high. The site geology consists mainly of Pumice Breccia and Limestone. Due to the existence of soft rock, the river is incised deeply forming very steep and rugged terrain in the area. The river flow is not steep and over 2 km of waterway with some high-cost tunnel section lined with concrete is required in rugged terrain to obtain about 40 m head. A 6 km access road is to be constructed for approaching the site and 13 km of 20 kV line is re- guired for sending the generated power to Port Vila. The peak and minimum demand of the Port Vila system in 1990 was 5,318 kW and 2,400 kW respectively, therefore all the - 42 - ANNX 3.3 Page 2 of 3 generated energy can be consumed in the system. Careful geological investigations by core drilling, permeability tests, material tests. etc. will be required to confirm the geological conditions of the site. The site is a recreation spot of Port Vila residents and the effect of constructing a hydropower project should be carefully studied. The Sarakata River roject is located about 10 km north-west of Luganville on Espiritu Santo island and can generate up to about 6,400 kW of electric power by fully developing the available head and discharge. However, the 1990 peak demand of the Luganville system was only 630 kW and the full output development cannot be justified at the present stage. Therefore, a staged development plan has been prepared and the first-stage development now being considered in to develop 1,000 kW by utilizing about 40 m head. The catchment area at the proposed intake site is 97 km2 and the annual mean flow is 8.78 m3/sec. The site is predominantly limestone terrain with raised limestone, which is overlaid by laterite. By utilizing a 16 m high waterfall and rapids just upstream and down- stream of the waterfall, about 40 m head can be obtained by leading water for about 700 m. The site topography is relatively gentle and low-cos- i;urface installation of waterway is possible by laying PVC pipes by Algging a trench into the lateritic soil. A motorable road which requires some reinforcement leads near to the river bank and only accesses going down to the intake and powerhouse sites will be required. For sending the generated power to Luganville, a 20 kV transmission line of about 13 km in length will be required. The permeability of the limestone bed rock should be confirmed by geological investigations. 3. Based on available information from past studies and the results of the mission's site visit, the Barakata project looks more attractive from the viewpoints of large available discharge, easier access, shorter and far cheaper waterway for similar head, ease of installation of the waterway, etc., while the length of the transmission line is almost the same. These factors result in a cheaper unit construction cost of the Sarakata project. According to the results of past prefeasibility and feasibility studies, the economic feasibility of the Teouma project is marginal, and may only become feasible at much higher oil prices. There seems to be little doubt about economic viability of the Barakata project if the demand in Luganville reaches 800 to 1,000 kW. 4. The Government of Vanuatu approached the Japanese government for technical and financial assistance for the 1,200 kW development (4 x 300 kW) 8arakata project, and the basic design study of the project will be commenced in April, 1991. Since the peak demand of the Luganville power system in 1990 was only 630 kW and the average growth after 1983 (peak demand of 490 kW) was 3.66g. This demand level will be too small to economically justify the execution of the construction works and if no special measures are taken, the project will be justified only after the year 2000. A significant demand - 43- AmX 3.3 Page 3 of 3 growth could only be realized by the connection of v'.llage loads adjacent to Luganville to the system, by establishment of industres and by extensions of the power system to other load centers in the island. An interconnection with Malekula island is not likely to be economically justified as the distance to Norsup. the largest load center in the island with 200 to 300 kW probable future peak demand, is 70 km from Luganville including a 15 km submarine section. Although GOV has already received an appllcation from UNELCO for developing this project, the government is now awaiting the results of the basic design to be conducted under Japanese aid. ANNEX 3.4 - 44 - Page 1 of 2 VANUATU ENERGY ASSESSMENT Mini Hydropower Projects for Rural Electrification 1. For electric power supply to rural demands by mini- to micro- hydropower projects, a Prefeasibility Study on Micro Hydropower Development for Rural Electrification was presented with German funding dated January, 1989. The rural demand of Vanuatu is very widely dispersed and the demand of rural centers rarely exceeds 20 kW, which makes economic development of micro-hydro projects difficult due to the negative effect of the economies of scale. Amongst these, the Brenwe/Unmet project of 215 kW capacity for power supply to the combined demand of village demands in the adjacent area and Norsup and Lakatoro towns in Malakula island is considered to be one of the better projects. As for the Woundaous/Navota and Kere/Fimele projects on Espiritu Santo island near Luganville, priority for power supply should be given to supply from Luganville by extending the high tension system. If the Sarakata hydropower project is executed, the additional cost for increasing plant output ill certainly be much smaller than the construction cost of a new mini-hydro plant. 2. The location of the Brenwe/Unmet project is on the west coast of Malakula island and is about 15 km west of Norsup on the east coast. The catchment area at the proposed intake site is 22.8 km2 and enough discharge is available to generate power to meet the demand in the supply area by utilizing the available head of 80 m. The project envisages to supply not only the five villages adjacent to the project but also Norsup and Lakatoro on the east coast. The area with these two towns is the most important center in Vanuatu next to Luganville and PWD is operating diesel power stations in these two towns. At Norsup, there is also a coconut processing plant which is operating its own diesel generators. Though accurate estimation of future ipower demand of such a center is very difficult, the combined peak demand is roughly estimated at 250 kW. A high tension transmission line of 5.5 or 11 kV will be required to deliver the generated power to the loads. 3. By commissioning a hydropower project, the power supply situation of the demand center will be much improved. The power supply area will be much enlarged from the Present PWD's limited supply. Instead of part-time supply by diesel generators, 24 hour supply will become available, and reliability of the power supply will be improved. 4. Though detailed data are not available, the electric energy generation cost by diesel generator is roughly estimated to amount to at least 50 to 70 Vatu/kWh and the economic viability of a hydropower project should be evaluated by comparison with this cost. The construction cost of this hydropower project will fall in the range of $5,000 to 10,000 per kW installation though this varies depending on various other conditions. ANNEX 3.4 - 45 ~ Page 2 of 2 5. For promoting the mini-hydro development plans, skilled staff in charge of the particular project will be essential. The staff for operation and maintenance of mini-hydro power plant will not be readily available in the rural community of Vanuatu, and training of available electricians, mechanics or other potential staff should be conducted during construction and the commissioning tests, if minihydro projects are implemented. ANNEX 3.5 -46- Page 1 of 11 VANUATIs ENERGY ASSESSMENT Biomass and Solar Options 1. Sawmill/Logging Residues: Total logs cut in Vanuatu in 1989 were estimated at 36,600 m3 (Table 1). This comprised 15,100 m3 of export logs and timber and 21,540 m3 for domestic timber consumption. While the total log cuts have remained relatively constant over the past six years, the data clearly indicate a trend toward an increasing percentage of log consumption for domestic use (see Table 1). The Second Development Plan indicates that the Ministry of Agriculture intended to establish a ban on the export of logs by 1990. However, the 1989 data indicates that of the total volume of logs cut for export, only 17X, or approximately 2,600 m3 of logs, were processed to timber products for export. Total sawn timber production in 1989 is estimated at 11,000 m3. The resulting sawmill residues from this production are estimated to be approximately equal to 13,300 m3 and the logging residues are approximately equivalent to 24,100 m3. The logging residues from export logs are estimated at 12,500 m3. Thus the estimated total logging and sawmill residues in Vanuatu in 1989 are equal to approximately 50,000 m3 or equivalent to 11.90 mtoel/ in terms of potential energy value.

Forestry Plantations: The Forestry Department continues to maintain two forest plantation programs: the Local Supply Plantation (LSP) program; and the Industrial Forestry Plantation (IFP) program. The LSP program is intended to help supply future local demand for sawn wood and timber. The LSP program was started in 1975 and by 1985 approximately 34 sites had been established covering 1,064 ha. The IFP program is intended to provide for future exports of lumber and to support an expanded wood processing industry. By 1986, the IFP program had established 8 sites which represented 1,128 ha. The primary objectives of the LSP and IFP programs were to provide an assured future supply source of timber for local and export needs. However, to date these ]/ Assumes 0.7 ton wood/m3 wood and 0.34 toe - 1.0 ton of wood at 30X mewb. ANNZX 3.5 47 Page 2 of 11 supply sources have not been brought into production as the expected increases in domestic and export volume have not materialized. These plantations represent a potential source of fuelwood derived from their pruning and thinning as standing timber, if the expected demand for timber does not materialize. Assuming an availability of lm'/ha/yr from pruning and thinning results in a woodfuel equivalent of approximately 0.52 mtoe/yr. 3. Coconut Residues: It was estimated that Vanuatu produced approximately 312 million coconuts in 1989a/. From this production, Vanuatu exported 24,906 tons of copra and consumed the equivalent of 17,801 tons of copra (mostly in the form of fresh coconut). Approximately 2.98 kg of husk and shell (at 30% mcwb) are produced per 1.0 kg of dried copra. As a results total husk and shell residues from coconut production is estimated at 127.3 x10' tons or equivalent to 43.3 mtoe. Approximately 29.2 x103 tons of husks and shells are consumed for copra and cocoa drying leaving about 98.1 x103 tons/yr of husk and shells unused. This is equivalent to 33.35 mtoe/yr. 4. Coconut Stemwood: In addition to the coconut husks and shells, there is a significant energy potential from senile coconut trees. The last agriculturil census carried out in 1983/84 estimated 91,291 ha of coconut plantations of which about 21% are large plantations and the remaining 79% are smallholderso/. Coconut trees have a productive life of approximately 50 years. At present however, it is estimated that over 25% of the coconut groves in Vanuatu are over 50 years and another 25% are expected to enter this category in the next 15 years. Copra production has declined significantly in Vanuatu over the past three years due to damage from major cyclones also resulting in a large number of unproductive trees, and also due to a drop in copra prices. 5. Coconut trees number between 100 and 150 per hectare. Given the relative high age profile of coconut groves in Vanuatu, it is reasonable to expect a replacement of approximately 4%/yr or 2,400 ha/yr of plantations which is consistent with the reported 1,600 ha planted by just the smallholders. Takino the conservative estimate of 100 trees/ha results in the approximate replacement of 240,000 trees/yr or equivalent to approximately 53.3 mtoeA/. The senile coconut stemwood is not used widely as a domestLc fuelwood substitute because it is difficult to chop into the appropriate sizes for cooking needs. However, the stemwood could be used as a supplementary fuel for copra drying or as an input to a coconut husk and shell direct combustion co-generation plant at major plantations. The constraints to utilizing coconut stemwood in these applications are due primarily to (a) the difficulty of cutting or chipping the stemwood; (b) the high silica content of 2/ Vanuatu Statistical Bulletin .15/10/90: "Copra and Cocoa - 1981 to 19890. t/ "Report on the smallholder Agricultural Survey - 1989", Statistics Office, NPSO, Port Vila, April 1990.

These OPV laniterns" use photovoltaic cells to charge a 12 or 24 volt storage battery during daylight hourb which is then capable of supplying up to six hours of light. The PV lanterns are designed with a high-inter.sity. low energy (5-11 watt) fluorescent light whlch provides over ten times as much light (when measured in lumens) than the conventional kerosene wick lantern. The conventional kerosene lantern, widely used in the un-electrified areas of Vanuatu, is estimated to have a conversion efficiency of only one percent.v/ Ar a result, the cost of lighting with kerosene wick lanterns is relatively ewL,.-nsive and inefficient. Kerosene pressure-type lamps are also available, giving higher-quality light. 7. At present, the cost of PV lanterns is extremely high, approximately US$190 per lantern. One of the major reasons for the high costs is the relatively low demand for such devices in most developed countries. Mass production of these lanterns in a country like India, where there are presently an estimated 100 million kerosene lanterns in use, could significantly reduce the costs of the PV lanterns to one-third of their present costs or about us$65 per lantern. 8. A comparison of the costs of lighting with kerosene lanterns versus PV lanterns is presented below. At the current cost of 70 Vt/l of kerosene, average daily lighting costs due to kerosene consumption are estimated to be approximately 17 Vt/d. Alternately, the costs of the PV lantern is estimated to be nearly 20 Vt/d. This does not account for the fact that the PV lantern ~/ Source: World Bank, Industry and Energy Department Working Paper, Energy Series No. 6. _ 49 - ANNEX 3.5 Page 4 of 11 provides a brighter light. If, however, the mass production of PV lanterns are realized as is being presently investigated in India, the daily price of PV lighting could fall to about 8 Vt/d. 9. Solar Electricity% Solar PV electricity, especially in isolated rural areas, where small diesel generators (less than 10 kWe) are used, can be considered for housing and community lighting, television, radio and some refrigeration. The exact economics of such a case is dependent on the costs of the PV systems and the price of diesel. A simple analysis of a solar PV community electricity system versus a 2.5 Kwe diesel system is presented below. The results indicate that a solar PV system could be only slightly more expensive than the diesel system at diesel prices of 100 Vt/l. At this price the cost of electricity is estimated at 96 Vt/kwh from the diesel system versus 103 Vt/kWh from the solar PV system. This does not account for the fact that the PV system has a greater reliability. It can be seen that at approximately 110 Vt/l for diesel the solar system becomes competitive. Given the remote locations of most rural areas in Vanuatu, the financial and economic prices of diesel can be beyond the rate of 110 Vt/l. Thus, The potential to use solar PV systems in these areas should be carefully evaluated. 50 - ANNEX 3.5 Page S of 11 VANUATU ENERGY ASSESSMENT VANUATU: BIOMASS GASIFIER ANALYSIS Basic Perameters Financial Economic Discount Rate () 10.001 ?0.001 Diesel Fuel Costs (Vt/I) 100.00 60.00 Wood Fuel Costs (Vt/kg) 10.00 16.00 Lube Oil Coste (Vt/I) 150.00 190.00 Skilled Labor Costa (Vt/hr) 250.00 200.00 Unskilled Labor Coste (Vt/hr) 100.00 76.00 Dlesl Energy Content (NJ/I) J6.00 86.00 Wood Energy Content (MJ/kg) 16.00 16.00 Unit Energy Costs - Diso l (Vt/MJ) 2.78 2.22 Unit Energy Costs - Wood (Vt/UJ) 0.68 0.94 Base OhU Costs (1 of Cap Costs) 5.00X 6.001 Annual Operating Days/yr 850 8$0 Import Duties (X) 80.00X Standard Conversion Factor 0.9 Daily Operating Hours 8 Average Plant Load Factor 0.6 Dlesel Imported aeslfier Local Gasifier Financial Economic Financial Economic Financial Economic Net Plant Capacity (kWe) 26 25 25 26 26 26 Plant Life (yr) 16 15 16 15 15 16 Capital Costs Engine/Gonerator (Vt) 2,000,000 1,400,000 2,818,800 1,978,160 2,400,000 1,680,000 Gasifiar (Vt) 0 0 5,687,600 6,687,600 2,000,000 1,800,000 Shipping & Handling (Vt) 800,000 270,000 1,602,200 1,861,980 600,000 460,000 Installation Costs (Vt) 690,000 501,000 2,987,680 2,688,822 1,470,000 1,179,000 Buildings (Vt) 700,000 700,000 1,000,000 1,000,000 1,000,000 1,000,000 Total Ins.
