The Nigerian Electricity Regulatory Commission (NERC), has said that the country’s power generation plants recorded an average availability of 32 per cent in February 2026.
Revealing this in its current operational performance fact sheet, NERC said 4,384 megawatts (MW) of generation capacity was available for dispatch from grid-connected power plants during the period under review.
The plants have an installed capacity of about 13,625MW, it said,stressing that the development means that only about one-third of the total capacity was available for actual electricity supply to the national grid.
The commission explained that the figure represents the grid-connected plants’ net average capability factor (PAF) for the month.
According to NERC, average hourly generation stood at 4,102 megawatt-hours per hour (MWh/h) during the month, indicating that 93 per cent of the available generation capacity was utilised.
It said that while the available capacity was efficiently dispatched, the overall supply remained constrained by low plant availability.
The fact sheet disclosed notable fluctuations in both voltage and frequency levels during the month in view.
The monthly average lower grid voltage of 302.00kV and upper grid voltage of 351.00kV exceeded the prescribed operational limits of 313.50kV to 346.50kV, indicating deviations outside the acceptable operating band.
Besides, grid frequency stability also recorded breaches of regulatory thresholds.
NERC stated that the average lower grid frequency was 49.28Hz while the upper frequency averaged 50.60Hz, exceeding the permitted operating range of 49.75Hz to 50.25Hz.
