Nigeria’s national power grid has suffered another system failure, cutting electricity supply to large parts of the country and leaving millions of residents and businesses without power.

Available data showed that power generation fell sharply from over 4,500 megawatts to about 24 megawatts by 1:30 pm during the collapse.

All 23 power generation companies connected to the grid were affected, leading to zero power allocation across the country’s 11 electricity distribution companies.

The exact cause of the grid failure was not immediately clear, as officials of the Transmission Company of Nigeria had not released a detailed explanation at the time of filing this report.

The incident represents the first national grid collapse recorded in 2026 and comes just weeks after a similar system failure on December 29, 2025, which triggered widespread blackouts nationwide.
