Nigeria’s grid-connected power plants utilised 85 per cent of their available generation capacity in October 2026, with average hourly electricity generation recorded at 4,047 megawatts (MW).
This is contained in the October 2026 Operational Performance Factsheet, of the Nigerian Electricity Regulatory Commission on Wednesday which showed that the average available generation capacity during the month stood at 4,744MW.
The report highlighted Jebba_1 as the best-performing power plant in terms of load factor, recording 99 per cent utilisation with 423MW generated out of its 429MW capacity.
Omotosho_1 followed with a 97 per cent load factor, generating 179MW out of 183MW, while Afam_2 recorded 94 per cent, with 371MW generated against an available capacity of 395MW.
However, the factsheet raised concerns over grid frequency stability, indicating that the average lower frequency of 49.46Hz and upper frequency of 50.66Hz fell outside the prescribed operational range of 49.75Hz to 50.25Hz.
It also highlighted voltage stability concerns, as the monthly average lower grid voltage of 305.00kV and upper voltage of 353.94kV exceeded the stipulated operational limits of 313.50kV and 346.50kV, respectively.
The figures provide an overview of generation performance and operational stability challenges across Nigeria’s grid-connected power plants during the month under review.
