Nigeria's Top 10 Power Plants Generate 81% of Electricity

As of April 2026, ten power plants in Nigeria account for 81% of the nation's total electricity output, according to the Nigerian Electricity Regulatory Commission (NERC). The overall availability of power plants remains weak, with only 4,286 megawatts (MW) of the 13,625 MW installed generation capacity available for dispatch, translating to an availability factor of 31%.

Despite this low capacity, the sector recorded an average hourly generation of 4,048 megawatt-hours (MWh), representing a load factor of 94%. The grid operated outside prescribed voltage and frequency limits, with average lower grid voltage falling to 302.60 kilovolts (kV) and average upper voltage rising to 353.40 kV.

Frequency stability also remained outside operational standards, with lower frequency dropping to 49.20 hertz (Hz) and upper frequency reaching 50.76 Hz. The Egbin power plant was the largest contributor, achieving an availability factor of 42% and a load factor of 93%.

Other notable plants included Kainji Hydro and Jebba Hydro, which also performed well in terms of availability and load factors.
