Nigeria’s electricity grid suffered a collapse on Wednesday, marking the first such incident of the year.
Data from the Independent System Operator (ISO) indicated that power generation plunged from 2,917.83 megawatts (MW) to just 1.5 MW between 11 a.m. and 12 p.m.

“Rest assured, we are working closely with the relevant shareholders to ensure power is restored once the grid is stabilized. Thank you for your patience and understanding,” the company added.
Earlier in the year, on February 12, several parts of the country experienced a blackout after the grid went down — a development confirmed by power distribution firms.
That same day, the Transmission Company of Nigeria (TCN) rejected reports alleging that the grid had collapsed twice in 2025. Similarly, in January, the company also dismissed claims of a shutdown.

On July 4, the Nigerian Electricity Regulatory Commission (NERC) reported there had been no grid collapse in the first quarter of the year, though it urged the system operator to enhance coordination of its operations.
The country’s fragile power grid has faced repeated failures. In 2024 alone, there were 11 recorded nationwide collapses, causing widespread blackouts.
