8 Demand Forecast ctd. Target and Moderate forecast Analysis made on historical sales and GD data for the period 1973 to 2007 reveals that the electricity demand has an elasticity of 2.15 to changes in the overall GD. If an economic growth rate of 7-10% can be achieved in the coming years, it could be translated to an electric energy demand growth rate of about 17%(as projected in the target scenario) based on the above elasticity estimate. April 11

9 Looking at the most determinant factors of energy demand growth factors GD and opulation,the recent good economic performance of the country as demonstrated in the three consecutive years GD growths of more than 10%.The coming five years growth assumed to be same. Similarly population growth expected to be 2.2 to 1.8 %

10 25.00% Yearly Demand Growth 25% 20.00% 15.00% 10.00% 6.07% 11.56% 7.86% 5.00% 0.00% 1999/ / / / / / / / / /09 21% 10.48% 13.14% 9.98% 15.04% 16.54%

11 Areas In which ower Supply was requested in 2009 and 2010 Gebreguracha & Surrounding 400 MW Diredawa & Surrounding 120 MW Bishoftu & Surrounding 150 MW Muger, Addis Alem & Surrounding 110 MW Addis Ababa, Sebeta & Surrounding 200 MW Other laces 410 MW It is clearly shown that due to the suppressed demand we have for the next tow years estimated to become more than 30%

12 Generation Expansion lan In compliance with prescribed reliability and system reserve criteria, an updated schedule for implementation of new generating plants and transmission additions is designed, to meet the projected demand. The generation development plan consists mainly of hydro projects. Generation from Wind and Geothermal power plants are foreseen to compliment the hydro.

28 Regional Interconnection The development of regional infra-structure projects (power system interconnection projects) is important for most African countries as they are typically very small to generate the economies of scale that can be found in larger markets. In light of the present world energy crisis, interconnection of the regional electric energy networks is the best alternative to displace expensive thermal generation in regional as well as international power markets. In harmony with this belief Ethiopia has devised a strategy for accelerating cross-border electricity trading with the neighboring countries and further to other nearby countries to spur regional economic growth through developments of the untapped hydro resources for electricity. April 11

29 Regional Interconnection Ctd. Benefits to be expected from developing regional interconnections and operating as a power pool, when considering further strategic links such as South African power pool (SA), East African power pool( EA), North African power pool (NA) and West African power pool (WA) include:- 1.Strategic partnership among the parties, which will have significant contribution for regional economic cooperation and stability. 2.Lower unit energy costs for the receiving system (s) from displacement of more expensive and environment unfriendly thermal generation.
