Ethiopian Electric Power owns and operates the Ethiopian national power grid with all high voltage power transmission lines above 66 kV[1] including all attached electrical substations and almost all power plants within the national power grid (with the exception of some co-generation power plants belonging to the state-owned Ethiopian Sugar Corporation). Ethiopian Electric power is almost the state monopoly in generating electric power for the national power grid, although Ethiopia also allows Independent Power Producers to construct and to operate power plants for delivering power to the national grid since 2017.
