EEPCO in Brief

ETHIOPIA
Location	Horn of Africa
Area	1.1 million km²
Population	66.5 million
Hydro Power Potential	More than 45,000 MW

EEPCo - Establishment

The Ethiopian Electric Light and Power Authority (EELPA), which was established in 1956, after having undergone restructuring has been reorganized as the Ethiopian Electric Power Corporation (EEPCo). EEPCo is responsible for generating, transmitting, distributing and selling of electricity nation wide.

Supply System

Presently the Corporation maintains two different power supply systems; namely, the Interconnected System (ICS), which is mainly supplied from hydropower plants, and the Self-Contained System (SCS), which consists of mini-hydropower plants and a number of isolated diesel generating units that are widely spread over the country.

Electrification Status

Number of electrified towns under EEPCo are 1658, 22% (at the end of 2004/05 which were 16%) of the population have access to electricity.

Inter Connected System ( ICS)

The ICS consists of 8 hydro, 13 diesels and one geothermal power plant with total installed capacity of 669.9 MW, 112.2 MW and 7.3 MW respectively. However, due to aging of the plants the dependable total capacity is only 721.1 MW. Over 96 % of the total generation in the country comes from the ICS.

Self Contained System ( SCS)

The SCS consists of three small hydro power plants and several diesel power plants. Generation in this system is mainly by diesel power plants having an aggregate capacity of 31.7 MW. The contribution from the small hydropower plants is only 6.15 MW.

4. TRANSMISSION

Transmission System

The high voltage network consists of both 230 kV and 132 kV transmission voltages, and 66 kV & 45 kV sub-transmission voltages. Presently there are 8,003.93kms of lines in service.
