Nigeria’s electricity grid collapsed on Wednesday, marking the first nationwide outage of the year.
Data from the Independent System Operator (ISO) showed that power generation plummeted from 2,917.83 megawatts (MW) to just 1.5 MW between 11 a.m. and 12 p.m.
Confirming the incident in a post on X (formerly Twitter), the Abuja Electricity Distribution Company (AEDC) said the collapse resulted in a total loss of supply across its franchise areas.

“Please be informed that the power outage currently being experienced is due to a loss of supply from the national grid at 11:23 a.m. today, affecting electricity supply across our franchise areas,” AEDC stated.
“Rest assured, we are working closely with the relevant stakeholders to ensure power is restored once the grid is stabilized. Thank you for your patience and understanding.”
The latest incident comes after months of relative stability. On February 12, several parts of the country were thrown into darkness following a grid collapse, though the Transmission Company of Nigeria (TCN) denied reports that the system had failed twice in one day.
In July, the Nigerian Electricity Regulatory Commission (NERC) confirmed that no grid collapse had been recorded in the first quarter of 2025, but advised system operators to strengthen coordination to prevent outages.
Nigeria’s power grid remains fragile, having recorded 11 nationwide collapses in 2024 alone, each leaving millions of homes and businesses without electricity.
