Nigeria’s electricity generation has declined further due to a major shortfall in gas supply to thermal power plants, according to the Nigerian Independent System Operator (NISO).
Newsonspot reports that in a statement issued on Thursday, the grid operator disclosed that the persistent gas supply constraints have disrupted operations at several thermal power plants across the country, forcing multiple generating units to shut down.
The agency revealed that the situation led to a reduction of about 292 megawatts (MW) in available power on the national grid.
According to NISO, as of 05:00 hours on Thursday, March 5, 2026, total electricity generation on the national grid stood at 3,940.53 MW, already below the expected capacity due to existing gas supply limitations affecting several generating stations.
The situation worsened between 06:00 and 08:00 hours, when several power-generating units were forced offline because of inadequate gas supply to the plants.

Operational data reviewed by the system operator also highlighted a significant gap between the amount of gas required by power plants and what is actually supplied.
NISO explained that generating stations need about 1,588.61 million standard cubic feet (mmscf) of gas per day to operate at optimal capacity. However, only 652.92 mmscf was supplied as of March 4, representing roughly 40 percent of the required volume.
The agency noted that the shortage has significantly reduced electricity available for dispatch to the national grid, further worsening power supply challenges across Nigeria.
NISO added that it is currently working with affected Generation Companies (GenCos) and gas suppliers to address the supply disruptions and restore normal generation levels once gas deliveries stabilise.
The grid operator also stated that operational measures are being implemented to maintain grid stability while managing the impact of the reduced generation capacity.
Despite the setback, NISO assured stakeholders and the public that it remains committed to providing updates on developments affecting Nigeria’s national electricity grid.
