Nigeria’s average available electricity generation has declined to approximately 4,300 megawatts (MW), largely due to inadequate gas supply to thermal power plants, according to a statement issued by Management on Thursday.

In the notice dated February 27, 2026, the management attributed the reduced grid output to significant gas supply limitations affecting thermal generating stations, which constitute the dominant share of the country’s power generation mix.

The statement explained that thermal plants collectively require an estimated 1,629.75 million standard cubic feet (MMSCF) of gas per day to operate at optimal capacity. However, as of February 23, 2026, actual gas supply to the stations stood at approximately 692.00 MMSCF per day — less than 43 percent of the required volume.

The shortfall, the management noted, has directly constrained generation output and reduced the volume of electricity available on the national grid. Consequently, energy allocation to Distribution Companies (DisCos) has also been impacted.

“With thermal plants accounting for the bulk of Nigeria’s generation capacity, any disruption or limitation in gas supply significantly affects available generation and overall grid performance,” the statement said.

Due to the reduced system generation, the Independent System Operator has been compelled to implement load shedding across the network. Available energy is being dispatched in accordance with the allocation framework set out in the Nigerian Electricity Regulatory Commission’s (NERC) Multi-Year Tariff Order (MYTO), to ensure equitable distribution and maintain grid stability.

Management expressed regret over the inconvenience to electricity consumers and market participants but assured that efforts are ongoing to restore full generation capacity. The organisation said it is working closely with relevant stakeholders to improve gas supply to thermal plants and enhance overall system reliability.

The development underscores the persistent vulnerability of Nigeria’s power sector to gas supply disruptions, given the heavy reliance on thermal generation for national electricity output.
