EEPCo Establishment
The Ethiopian Electric Power Corporation (EEPCo) was named in 1997 after serving in the name of Ethiopian Electric Light and Power Authority(EELPA) which was established in 1956.
EEPCo is responsible for generating, transmitting, distributing and selling of electric energy through out the country.
Supply system
The corporation has two electric energy supply systems.These are the Inter - Connected System (ICS) and the Self Contained System (SCS). The main energy source of ICS is hydro power plants and also the SCS are mini hydros and diesel power generators allocated in various areas of the country.
Electrification Status
The number of electrified towns and rural villages, highly increased for the last five years of the strategic plan period and by July 7, 2011 reached to a total number of 5,866 which brought the electric energy access to 46%.

Inter-Connected System (ICS)
The ICS consists of 11 hydro, 13 diesel standbys and one geothermal power plant with total installed capacity of 1842.60 MW, 112.3 MW and 7.30 MW respectively.
Self-Contained System (SCS)
The SCS consists of two small hydro and several diesel power plants. Generation in this system is mainly by diesel power plants having an aggregate capacity of 35.87 MW. The contribution from the small hydropower plants is only 6.15 MW. Dembi small hydro power plant with 0.8 MW was out of operation since 2009/10.

Transmission and Substation
The electric energy generated from the main hydro power plants is transported through high voltage transmission lines rated 45, 66, 132, 230, and 400 kV. The total length of the existing transmission lines is about 10,812.02 km. The existing transmission lines status by voltage level is categorized:
The total figure includes lines of 245.3 km from SCS.
Supply of the distribution network is provided by step down substations connected to the respective transmission and sub-transmission voltages. In total there are 131 transmission substations supplying the distribution system. The existing substations by voltage level are categorized:
Note. The total number of substation is 138 which include additional substation 11 at power house,3 small hydro and 1 stand by at diesel power house.
Distribution
Power distribution in both ICS and SCS is effected at a primary voltage of 33, 19, 15 and 11 kV, consisting entirely of 3-phases, 3-wire feeders, and is stepped down to a utilization voltage of 380/220 V (3-phase, 4-wire) using 3-phase transformers to customer’s level. The distribution system consists of 138838 km of 33 kV, 19 kV, 15 kV and 11 kV; and 380/220 V lines; and 17,445 distribution transformers. The total distribution line status for the last five years:
Number of Customers
Number of customers are those who are connected to get electric energy. The total number of connected customers at present has been reached 1,900,000. The number of customers who are connected in the ICS and SCS of EEPCO is depicted as stated respectively. Number of customers include active, suspended, in process and pending ones for 2010/11. ICS domestic and own consumption customers of 2008/09 are adjusted.
