The Energy Sector Review is based on the findings of a Joint World Bank/International Atomic Energy Agency (IAEA) mission which visited Armenia in May/June 1992. The World Bank team was composed of Joseph Gilling, Senior Energy Economist Oeader); Peter Law, Gas Specialist; Kurt Schenk and Edwin Moore (cons), Power Engineers; and Arnold Safer (cons), Petroleum Specialist. The IAEA team consisted of Bernard Gachot, Nuclear Safety Specialist and Antonio Godoy, Seismic Specialist of the Safety Assessment Section, Division of Nuclear Safety. The mission worked closely with the Ministry of Energy and Fuels and the Energy Planning team led by Garen Galustian, Deputy Minister. Powr Demand and Supply Options i EXECUTIVE SUMMARY i. The communique of the 1992 G-7 summit meeting in Munich included a number of proposals related to the safety of nuclear power plants in the countries of the former Soviet Union and Central and Eastern Europe. The G-7 communique suggested that "the scope for replacing less safe [nuclear] plants by the development of alternative energy sources and the more efficient use of energy' should be studied, and, "together with the competent international organizations, in particular the IEA, the World Bank should prepare the required studies including replacement sources of energy and the cost implications." This study has been prepared in response to the request from the G-7. ii. Armenia's only nuclear power plant (NPP) is a 2x408 MW VVER 4401230 station. The first unit was commissioned in 1976 and the second in 1979. It was shut down in early 1989 for safety reasons following the 1988 earthquake, since it is located in a seismic zone. However, because the country .s under a virtual state of siege as a result of the onguing conflict with Azerbaijan and is suffering severe energy shortages, the government is exploring all options to increase the supply of fuels and increase energy security. While the government is seeking alternatives to recommissioning the NPP, at the same time it is assessing the technical requirements for upgrading and recommissioning the plant. The -IEA mission that worked jointly with the World Bank missiorn found that the plant suffers the same deficiencies as others of its class. Furthermore, because of its situation in a seismic area, IAEA has recommended that additional evaluation of existing data and field work be carried out as necessary to confirm that there is no seismic fault on or near the site that would preclude further consideration of recommissioning the plant. iii. The government is well aware of the national and international concerns for nuclear safety but is also confronted by several major issues including: * the increased dependency on Russia, Turkmenistan, Azerbaijan, and Georgia for fossil fuel imports under a no nuclear scenario * Armenia's growing difficulty in meeting the balance of payments impact of increases of fuel costs to world price levels in the near to medium term * the large capital requirements for the power sector needed to ensure reliable electricity supply to help sustain economic recovery and growth regardless of the decision concerning the nuclear power plant. iv. The costs of upgrading and recommissioning the NPP have yet to be fully assessed. Estimates to permit five years' further operation range from a minimum of US$70 million (IAEA) for recommissioning the plant with some upgrading (but not to international standards), to US$330 million (consultants to EBRD, March 1993), or to about US$370 million (based on Framatome's March 1993 report) for more extensive upgrading, and recommissioning (including an initial fuel charge). Further upgrading to international standards to permit operation to about 2010 (i.e. to the end of its normal service life of 30 years allowing for the period of shutdown) together with recommissioning is estimated by consultants to EBRD at US$460 million. In the short term, however, regardless of whether or not it is to be recommissioned, the plant must be maintained in a safe shutdown condition; safety upgrades under current shutdown conditions are also urgently needed to ensure reliable electricity supply and physical security. ii Armenia v. Armenia currently depends on imported fuels for 95% of its primary erergy requirements. The nuclear plant, if operating, could supply about one-half of 1993 electricity requirements Mund 18% of total primary energy needs. Because of the transportation blockade ar.sing primarily to'om the Nagorno-Karabach conflict but also because of disruptions in and decline of supply of oil, gas and electricity from countries of the former Soviet Union (FSU), Armenia has suffered from energy shortages since 1991. Energy supplies in 1991 and 1992 were limited to 89% and 81% of the 1990 level respectively, the most recent year when demand was generally satisfied. Fuel stocks are now fully depleted and about US$165 million (at world price levels) would be required to fill existing oil and gas storage facilities, of which about US$68 million would be for power generation. vi. Energy shortages have crippled the economy and, in winter, have caused death from hypothermia especially to the elderly and the very young. Severe fuel and electricity rationing has been imposed while minimal quantities of fuel and electricity are being allocated to high value added export industries, essential services, and to the population. The private sector is active in importing petroleum products for which there is a ready market but selling prices are driven up by high transportation costs and market forces stemming from limited supply. vii. The degree to which indigenous resources could satisfy Armenia's requirements in the long run has not been fully determined but it is likely to be less than half. Coal and peat may be economic to develop; prospects for gas and petroleum in commercial quantities are encouraging; small hydro plants and other renewable resources can also be developed. These projects can contribute to energy supplies in the medium to long term but will require capital and time for implementation. Immediate efforts must, therefore, focus on rebuilding the fuel stocks and increasing the average rate of supply to meet minimum human and productive needs. At the same time, improvements in energy efficiency must be achieved in the short term to make more effective use of available fuel supplies. viii. Hydro power is presently the orly significant indigenous source of energy which is currently exploited and provides on average about 15% of total generation but only 5% of total primary energy requirements. Because of the lack of alternative fuels, there has been no choice except to continue to draw down Lake Sevan, the only large storage reservoir, for hydro generation despite the ecological consequences and the loss of water for irrigation. High rates of generation, reaching 500 MW from all hydro sources as required this past winter when no gas and mazut were available, cannot be sustained beyond the next 12 months as level of Lake Sevan will drop to the sill of the intake works. ix. Nominally, the current installed capacity of '699 MW (1746 MW thermal, 953 MW hydro excluding the nuclear plant) would appear to be sufficient to meet projected demand; however, much of this capacity must be derated due to age and condition. Firm capacity of hydro plants during the winter time peak demand period is limited to 400 MW due to hydrological restrictions and the need to store water for irrigation in summer, while firm thermal capacity is about 157j MW. Total firm capacity (1971 MW) is thus limited to 73% of installed capacity. Reserve capacity in 1993 with unconstrained demand would be at most 9% while a minimum of 25% is required. x. Gross generation in 1991 was 9516 GWh, of which 7970 GWh (84%) were from thermal power plants burning heiavy fuel oil/natural gas and 1546 GWh (16%) from hydro while electricity imports amounted to 15'2 GWh or 14% of total supply. Because generation in 1992 was severely restricted due to fuel shortages, about 20% of total electricity demand was unsatisfied. Powr Demand and Supply Options iii xi. Interconnection totalling 1000 MW in capacity exist with Azerbaijan (450 MW), Georgia (250 MW), and Turkey (300 MW). Imports are presently limited to about 500 GWh per year from Russia via Georgia but do not provide firm power. Normally Armenia would wheel power from Azerbaijan to the Azeri territory of Nach.ichevan through an existing 400 MW capacity lines, however, all transfer has stopped because of the conflict. xii. There has been virtually no growth in power demand over the past decade. Maximum consumption peaked in 1983 at 9572 GWh (2344 MW) and dropped by 10% by 1991 despite a doubling of residential and commercial consumption and a 50% increase in agricultural use. These increases were met by a corresponding decline in industrial consumption. Industrial usage still remained the largest component at 32% of total. Demand has been so severely rationed since 1992 that current figures are not representative of unconstrained consumption patterns. xiii. Under the base case scenario for economic development estimated by the World Bank with Armenian authorities, it is projected that a return to the 1990 GDP level (from its present level of 40% of 1990) could be achieved by 2008 with an average growEh of 5.8% p.a. from mid 1993. Despite the decline in the economy, current electricity needs are estimated to be in the order of 80% of historical levels because of the high use of electricity for heating and the high fixed energy component in the economy. A resumption of economic growth would start the process of reducing the electricity intensity (consumption per unit GDP) in the economy, while furlher reductions would occur as the result of energy conservation programs and economic restructuring. xiv. Electricity demand projections as well as the underlying current level of unconstrained demand are uncertain because of the great uncertainties surrounding economic growth and the possible future reduction of electricity intensity. Unconstrained power demand is estimated presently to be about 1800 MW. Under the base case scenario, demand is projected to decline to about 1730 MW in 1995, then rise to about 1900 MW by 2000, reaching the 1990 level of 2146 MIW by 2003. These estimates are based on assumptions relating to economic growth (para. xiii) and to the various measures which are needed to be adopted including price increases to reflect supply costs, the substitution of district heating and gas for electric heating in households and industries, and energy efficiency improvements on the supply and demand sides. xv. To assess the options to meet the demand projections for the period 1993-2010, an indicative generation planning study was carried out by the Bank. Three basic power supply development scenarios were examined: * the low nuclear scenario in which it was assumed that the NPP would not be recommissioned * the moderate nuclear scenario assuming 5 years of operation of the existing NPP followed by closure * the high nuclear scenario with additional safety upgrades to permit extended operation for up to 15 years but with no replacement or additional nuclear plant. iv Armenia xvi. Investment and fossil fuel cost estimates for the period 1993 - 2000 are summarized in Tables ESI and ES2 respectively below. All costs must be regarded as indicative because detailed planning studies have not been carried out. Unit costs of new plant capacity and rehabilitation are based on experience in the FSU and Eastern Europe as used in the overall G-7 study. While the absolute magnitude of costs are important, the difference in costs between the scenarios is of particular interest because of the implications for power sector strategy. xvii. Under the low nuclear, that is no nuclear scenario, and following the completion of the Hrazdan 5 thermal plant in 1995, capacity requirements .ould be met through a combination of rehabilitation and life extension of existing hydro and thermal plant where economic, the addition of small hydro ,lants, and installation of new more efficient generating capacity to optimize the plant mix. Work has begun with external assistance to assess the condition of all existing plants and the options for rehabilitation and life extension. 2urtdier studies for integrated resource planning are needed to assess more fully the options and capacity requirements for plant additions as well as the contribution which can be expected from demand side management and supply efficiency improvements. xviii. To meet the base case demand projections under the low nuclear scanario, capacity additions totalling 1900 MW would be required in the period 1993 to 2010, of which 1000 MW would be added in the period 1993-2000. Rehabilitation and life extension of existing plant would occur in the period 1993 to 2000 and 621 MW of plant, which is assumed to be uneconomic to rehabilitate, would be retired. xix. Total costs of the low nuclear/no nuclear scenario for power sector capital investments and fuel (excluding O&M) over the period 1993-2b 20 are estimated to be US$2.9 billion including US$3 million per year to ensure maintenance of the nuclear plant in a safe shut down condition. The capital cost of new plant and rehabilitation of existing plant is estimated at US$162 million in the period 1993-95 and a further US$730 million from 1996 to 2000 based on unit costs that reflect a mix of procurement from western and FSU countries for a total of US$892 million in the period 1993-2000. Fossil fuel costs at world prices would total US$710 million and US$1,255 million in the periods 1993-95 and 1996-2000 respectively. The average fossil fuel cost in the period 1996-2000 would be US$251 million/year at world prices. xx. Under the moderate nuclear scenario, restarting the NPP for five years' operation would substitute for 815 MW of conventional thermal plant capacity which otherwise would require rehabilitation and life extension plus fossil fuel for operation. After five years' operation it is assumed the NPP would be retired and replaced with conventional thermal plant in 2000. The cost of upgrading and recommissioning to permit five years' further operation is assumed to be US$370 million (based on the Framatome estimate) in addition to the US$892 million in the low nuclear scenario. This cost would be offset, however, by the avoided costs of thermal plant rehabilitation estimated at US$204 million yielding a net total investment cost of US$1058 million. Average fossil fuel cost savings of US$95 million/year could be achieved but nuclear fuel costs of about US46 million/year would be incurred. xxi. Under the high nuclear scenario, the NPP would be upgraded to international standards to operate beyond 2000, thereby deferring the commissioning of 815 MW of gas fired combined cycle plants having a total estimated cost of US$628 million. At a 10% discount rate, each year of deferrment would yield a saving of US$62.8 million. Total upgrading and recommissioning costs are estimated at Powr Dend and Supply Opdons v US$460 million (EBRD consultants) which net of avoided thermal generation rehabilitation cost would lead to total investment of US$1148 million. Fossil fuel savings and nuclear fuel costs would remain the same ss in the moderate nuclear scenario.

On the basis of the estimates so far available and without considering the risks associated with nuclear plant operation, the analyses in this report suggests that the nuclear scenarios could be higher in total capital cost but lower in fuel cost than the low nuclear/no nuclear scenario. While the capital rost of the high nuclear scenario at US$1.1 billion could be US$256 million higher than the no nuclear scenario at US$0.9 billion, this cost could be recovered in 34 years through annual net fuel cost savings through nuclear generation with continuing fuel cost savings for up to 15 years. The moderate nuclear scenario would have a 2-3 year payback but fuel savings would terminate after 5 years of operation. xxiii. As an alternative to the nuclear scenarios, however, it is important to consider the impact of lower demand on the capital and fossil fuel costs. A more rapid reduction in electricity intensity while meeting the same end-use requirements and supporting the same rate of economic growth as in the base case such that electricity intensity would drop to the 1990 level by 1999 and drop further to about 80% by 2010 would defer the return to the 1990 level of total electricty demand until after 2010. The resulting savings in capital and fuel under this scenario could amount of US$205 million and US$513 million respectively or US$718 million in total in the pericd 1993-2000. These savings could be used to finance fiurter economic restructuring and efficiency improvements beyond those assumed in the base demand case and could provide a significant non-nuclear alternative to electricity generation. vi ArwAn k xxiv.

Power Demand and Supply Options 1 1. INTRODUCIlON 1. This report was prepared as part of the overall study of non-nuclear power generation alternatives in Central and Eastern Europe (1995-2010) being carried out at the request of the Group of Seven (G-7) (hence, referred to as the G-7 Study) by the World Bank in cooperation with the International Energy Agency (IEA) and the European Bank for Reconstruction and Development (EBRD). This report first discusses the energy sector in general, then goes on to focus on the power sub-sector to analyze the historical supply demand situation, develop projections, and evaluate alternative generation options to meet demarid. The report also shows projected energy requirements for power generation in terms of total primary fuels. Finally, the investment and financing implications of the options are discussed. 2. Armenia is a small, mountainous, landlocked country with a land area of 29,800 square kilometers and an ethnically homogenous population of 3.5 million. Turkey lies to the west, Georgia to the north, Iran to the south, and Azerbaijan to the east with one province to the south-west of Armenia (Map IBRD 24491). With few resources and stony land, Armenians have learned to survive though skill, ingenuity, and trade with those around them. The level of education is high, and the Armenian diaspora has a strong tradition of successful entrepreneurship which should work to the country's advantage in the difficult times ahead. 3. Two problems dominate the imnmediate future. First, Armenia is an economy under siege. Trade routes have been blocked because of internal disruption in Georgia over South Ossetia and Abkhazia and conflict with Azerbaijan over the enclave of Nagorno-Karabakh, with the result that Armenia's trade and, most importantly, its energy imports, have been cut to a trickle. Widespread starvation was only avertod by humanitarian grain shipments. Second, in common with all the countries of the Former Soviet Union (FSU), Armenia is experiencing falling economic output due in part to the disruption of the Soviet monetary, payments, trade and transport systems. Although a small country at the edge of the empire, Armenia was one of the most highly integrated republics in the Soviet system of production and trade and is suffering correspondingly now. 4. The Ministry of Energy and Fuel (MEF) has responsibility for policy formulation, sector planning, and supervision of the operating entities (see organization chart Annex 3) which have been formed into state companies. ARMENERGOPROD is responsible for electricity generation, transmission, and distribution as well as district heating production and distribution. ARMGASFUEL has three subsidiaries ARMPETROL (petroleum products), ARMGASPROM (high pressure gas transmission) and ARMGAZ (gas distribution). The nuclear power plant comes under the direct supervision of MEF. 2 Ameia II. O-VERVIEW OF ENERGY DEMAND AND SUPPLY A. Primary Energy Demand Historical Requirement 5. Armenia's total energy supply requirement peaked in 1988 at about 10.1 mtoe (million tonnes oil equivalent) as shown in Figure 1 and dropped to 8.3 mtoe in 1991. While Armenia imports 100% of fossil fuel requirements, it exported about 2900 GWh or 20% of total electricity generation up to 1989 when the nuclear plant was shut down. By 1991, Armenia became a net importer of electricity (1500 GWh/yr or about 17% of domestic generation) as gas supplies via Azerbaijan were restricted. Until 1988, internal production (hydro and nuclear) accounted for about 15% of Armenia's total energy requirements. 11.000- 1 0.000- 9.000 - 7te .0001I 4.000 LOJ 6.0001 6.000 VI 4 000. z .3.00 0 2.0001 1.0001 0 C .00 O- - E T-------r-- r 1985 1986 19!7 1988 1989 1990 1991 YEAR f ConsLrnptn + exportt + Domestic cosnptnsmp Dornestic production Figure 1. Historical Total Arnenian Primary Energy Demand Energy Intensity of the Economy 6. In 1990, Armenia's GNP per capita was about US$2380 and energy consumption about 2477 kgOE/capita giving an energy intensity of 1040 kgoe/000 $ GNP. Figure 2 shows a comparison of energy intensity with other countries in the range of US$ 1500 - 3500 GNP/capita. Armenia's energy intensity was roughly one-half that of Eastern European countries such as Bulgaria, Poland and Romania and comparable to that of Hungary and the former Federation of Yugoslavia with higher GNP/capita. Despite comparing favorably with formerly centrally planned economies, the energy intensity of Armenia's economy, however, was about double that of market economies with similar levels of GNP/capita including Brazil, Malaysia, Mexico, and Uruguay. While the high income (17,000 - 23,000 $GNP/capita) countries of Western Europe such as Austria, Germany, and Italy have energy consumption Power Demand and Supply Opdons 3 in the range 2700 - 3500 kgOE/capita or up to 40% greater than that of Armenia, energy intensity of the economy is less than one-fifth that of Armenia. Furthermore, the age of industrial plants and equipment in Armenia is above the average of the rest of the FSU and well above the age of plant in western countries which embodies newer, more energy efficient tochnologies. In general, energy intensity is lower in high income countries because of the low energy requirement of their much more developed service sector. 7. Energy intensity in Armenia has risen since 1990 because of the drop in GNP and the high fixed energy component in the economy. As a result, the data point for Armenia in 1992 is upward and to the left of the 1990 position. 2500 - ~2000- to xSov 0 Ar_"I%(l 92) 10500 , l r# O~~ ~ U I000 15 00 200 23500 4o300 sx GWP/CAPITA (1990 Us$) Figure 2.

In addition to meeting its own electricity needs, Armenia had been exporting electricity until 1989 to neighboring republics of the FSU via the Trans Caucasus system. After 1989 the importation of electricity began as shown in Table 1 which also shows total generation requirements and system maximum demand. As ARMENERGOPROD does not systematically record simultaneous system demand, it has been necessary to estimate maximum demand on the basis of a 60% annual load factor.' 1.

The existing generating facilities to meet the projected peak dernand and energy requirements are reviewed below and the generation planning options are discussed below together with an assessment of the capacity and energy balances. JO. Total nominal installed capacity is 2700 MW (excluding the 815 MW NPP), of which 1746 MW (or 65%) is steam thermal and 953 MW (35%) is hydro. Derating due to age and operating constraints plus the non-availability of the Sevan-Hrazdan Cascade during the winter, brings the effective installed capacity to about 1970 MW as shown in Table 2. On the basis of the demand projections (Section 1.C), the additional 300 MW capacity to be provided by Hrazdan 5 is needed immediately to meet peak load and provide a 25% reserve margin.

TL< share of thermal units in gross generation increased from about 55% in 1980 to 84% in 1991, althoubh the total generation dropped 18% between 1989-1991 because of a steady dropped in electrici-: consumption together with the shutdown of the NPP. Hydro units provided 12% of gross generation in 1980 and increased their share to 16% in 1991. By 1991, electricity imports from Russia via Georba and from Azerbaijan amounted to 1572 GWh or 14% of total electricity supply. 12.

Over the past decade there has been virtually no growth in total annual electricity consumption as shown in Table 4. Maximum consumption peaked in 1983 at 9572 GWh and dropped to 8635 GWh by 1991 despite a doubling of residential and commercial/official consumption and a 50% increase in agricultural use.2 These increases were met by a corresponding decrease in industrial consumption which declined by 50% (from 65% to 32%) over the decade from 5487 GWh in 1980. The percentage shares of each sub sector are presented in Table 5.

The largest industries are electronic equipment, footwear, mining, textiles, wine and cognac, chemicals and tires and machine tools. Despite the decline in industrial production, in part becaure of the shutdown on environmental grounds of the synthetic rubber plant,3 industry remains the largest consuming sector followed closely by the residential sector at 28% of total consumption. Load Charaedscs 15. Daily and monthly load factors have ranged from 80% to 89% in the winter months and 70-82% in the summer months during the period 1988-91. The average working day load curves for December, during the winter peak period (Figure 4), show a morning and evening peak. In 1991 the peaks were more pronounced as residential heating loads increased and high load factor industrial loads declined. Annual load factors have been in the 60 - 62% range since 1988 but by 1991, had dropped to 59.5% because of the shift in load composition. With constraints in energy supply, load shedding begun in late 1991 will continue and load factors will be higher than usual as a large portion of demand goes unsatisfied. 3. ae pkzr has been restarted Mi 1992 bw on a limned scale becawe ojf raw mawerials and energy shortages.

The normal seasonal pattern of energy consumption and peaak load are evident from Figures 5 and 6. Maximum demand and load factors in winter months are higher than in summer because of the longer duration of the increased heating and lighting loads. The peak load in summer months is about 20% less than in winter and provides an opportunity for carrying out scheduled maintenance.

MEF has carried out an initial power system planning study based on the highest demand projection shown in Figure 7. Under this scenario, the economy is assumed to recover rapidly with the increased supply of electricity and other forms of energy and grow from the 1990 level of demand (2146 MW) as experienced before independence and the blockade. This scenario does not take into account efficiency improvements on the demand side or reductions in electricity intensity that would occur with economic restructuring. By 2000, demand would reach 2500 MW (index value 115), 2760 MW (index 127) by 2005, and 2970 MW (index 140) by 2010. Under projected conditions of economic growth, the MEF scenario is considered to have a low probability of realization. Macro Economic Scenanos 19. There is considerable uncerainty in the economic development of Armenia. The 9000 Bank's medium/base case scenario has been used as the basis of electricity demand forecasting while the high and low forecasts are also 9 7000 presented in Figure 8 (absolute values) and Figure 9 (index series) and show the wide range of ! 6000 estimates. 20.
