Grid-connected power plants in Nigeria had an average of 4,758 megawatts available for dispatch in August 2026 and average hourly generation of 4,102 megawatts, according to an operational factsheet published by the Nigerian Electricity Regulatory Commission on September 24. NERC said this represented 86% of available capacity.

The factsheet reported monthly average lower and upper grid frequencies of 49.34 and 50.67 hertz, outside the prescribed 49.75–50.25 hertz range. Monthly average lower and upper grid voltages were 302.29 and 349.68 kilovolts, also outside the 313.50–346.50 kilovolt limits. Afam 2, Kainji 1 and Egbin 1 recorded load factors of 99%, 98% and 96%, respectively. These are NERC’s measurements for August, not an annual result or a claim about conditions at all times.
