Power sector infrastructure development in Albania Agim Nashi Advisor to ERE Board Historical data on power sector in Albania Power production and power supply of Production capacity of HPP varies residential and industrial consumers from 3.5-4.8 bl. kWh to 7 bl. kWh, started in 1923 by using diesel remote respectively, for the hydrological power plants with operational voltage security of 90%, 50% and 25% of 0.4, 3.6 and 16 kV Production capacity of TPP was 1.2 bl. In 1951, first power plants and kWh but actually all these power plants transmission facilities with operational are closed voltage of 35 kV were introduced 83 small HPP produce around 55 Year 1957 represents the creation of million kWh, their contribution in Albanian Power System and domestic production is not operational voltage of 110 kV is considerable, their importance is introduced mainly for rural areas where they are Nowadays, Albanian Power System located operates with high voltage of 220 kV Recently, ERE has licensed a and 400 kV company for construction of an Until 1990, there were 20 power plants offshore wind farm with installed with installed capacity of 1,670 MW, of capacity of 150 MW which Also, an application is under review for 11 HPP (1,446 MW) granting a construction license to an Italian company for an offshore wind 9 TPP (224 MW) farm with installed capacity of 500 MW There are also some other projects under construction: TPP Vlore, HPP Kalivac, HPP Sasaj and some other small HPP. Energy sources Generation, hydro energy reserves Energy sources Generation, hydro energy reserves Energy sources Hydro Generation Albanian Power System is insufficient and cannot secure a continued and qualitative supply for all consumers 99 % of production is from HPP, three of them are in the Drini River Cascade and provide 86% of total domestic production In a normal year, total production is about 4,160 GWh but this is insufficient to cover growing consumer needs HPP stations Installed capacity (MW) Actual capacity (MW) Gjenerimi Mesatar (GWh/a) HEC Fierze 500.0 152 1,328 HEC Koman 600.0 171 1,500 HEC Vau i Dejes 250.0 100 880 Kaskada e Drinit 1,350.0 423 3,708 HEC Ulzes 27.0 14 120 HEC Shkopetit 25.0 10 90 Kaskada e Matit 52.0 24 210 HEC Bistrica 1 23.0 19 165 HEC Bistrica 2 5.5 4 35 Kaskada e Bistrices 28.5 23 200 HEC e Vegjel 20.0 2 20 TEC Fier 159.0 10 76 Gjithsej 1,609.5 482 4,214 Energy sources Generation, hydro energy reserves Even though 98% of domestic production is from hydro resources, it is a fact that only 35% of hydro potential has been exploited so far Total reserves are estimated to be around 4,500 MW and potential annual production can reach 10-12 TWh Considering the fact that 95 % of HPP are located in the north of Albania, the attention is concentrated in construction of new facilities in south of Albania - on the Vjose and the Devoll rivers Most recent analyses prepared by national and international institutions emphasized that: Available generation capacity is insufficient and cannot cover the demand growth even when hydrologic conditions are favorable Available generation capacity is insufficient and cannot cover the demand during the peak time of the day/week/month/year For a better management of hydro reserves, it is necessary to improve production structure and to diversify it by constructing thermal power sources Energetic sources Generation, TPP As mentioned above, 9 TPPs have been decommissioned The below table presents main features of these power plants Energetic sources Generation, hydro energetic reserve of SHPP Until 1988, there were 83 small HPP constructed with installed capacity of between 30 - 5000 kW each The total installed capacity is about 14 MW and there are possibilities for increasing their capacity up to 25 MW by better exploitation of river flow Some studies are underway in order to identify possibilities for construction of other small HPP and increase of capacity for existing power plants and elimination of some deficiencies mainly in: Incomplete exploitation of hydro energy capacity Lack of frequency stability and voltage stability during load changes Frequent interruption of power plants from network Relatively high costs of equipment rehabilitation of small HPP The estimates have been made for about 41 new small HPP with installed capacity of 0.5–10 MW each to be constructed in the future Total capacity of these power plants will be about 140-150 MW and their annual production will be 600-680 GWh Energy sources Generation, alternative energy reserves Active exploitation of solar energy - If Albania develops photovoltaic and thermal panels for hot water production, equivalent energy spared will be 1000 GWhthermal (or 125 MWthermal installed capacity) Wind energy - Preliminary estimates show that areas with highest wind potential are located on the west coast where can be constructed 20 EC to be used for supplying 20 pump stations used for protection of land from flooding. It is expected that by 2020, domestic production from wind farms will be 400 GWh/year. With recent projects being licensed by ERE, these are very ambitious projections Potential for exploiting urban waste - Energy reserves of urban waste are considerable and in increasing tendency but production of energy with this kind of combustible has a high cost compared with other traditional fuels Geothermal sources - Albania has a lot of geothermal sources but these sources cannot be used for power production because their thermal potential is low (20-330C) Biomass is another source with a high spread in Albania. For the moment, it is not used efficiently and a lot of forests are damaged. It is mainly used in industry and for residential heating and there are as of yet no applications for power production. Biomass from agriculture is mainly used as food for livestock.
