Nigeria’s national power grid collapsed again on Tuesday, marking the second system failure in four days and the third in less than one month, deepening the country’s electricity supply crisis.
Power generation dropped sharply to just 39 megawatts at about 11 a.m., from 3,825MW recorded an hour earlier at 10 a.m. Monitoring data also showed that generation had peaked at 4,762MW as of 6 a.m. before the collapse.
As the incident unfolded, load allocation to all electricity distribution companies (DisCos) fell to 0.00MW, indicating that no DisCo was supplying power at the time of the grid failure.
Confirming the development, Eko Electricity Distribution Company (EkoDisCo) informed customers of a system collapse that led to a total loss of power supply across its network.
“Kindly be informed that there was a system collapse at 10:48 hrs, which has resulted to a loss of power supply across our network,” the utility said in a statement on Tuesday.
“We are currently working with our TCN partners as we hope for the speedy restoration of the grid. We will keep you updated as soon as power supply is restored. Kindly bear with us,” it added.
The Nigerian Independent System Operator (NISO) has yet to provide a detailed explanation for the latest collapse. However, it confirmed that the outage occurred at about 12:40 p.m. following the simultaneous tripping of several 330kV transmission lines.
The latest incident follows previous grid collapses on December 29, 2025, and Friday, January 23, 2026. Reacting to Friday’s outage, NISO said the combined incidents resulted in a total collapse of the interconnected national grid.
“The Nigerian Independent System Operator wishes to inform the public that at approximately 12:40 hours on Friday, 23 January 2026, the national grid experienced a system-wide disturbance, which resulted in a total outage across the interconnected network,” the statement read.
Frequent grid collapses have continued to raise concerns over the stability of Nigeria’s power infrastructure, with households and businesses increasingly reliant on alternative energy sources to cope with repeated blackouts.
