Nigeria’s national power grid suffered another collapse on Tuesday, marking the second system failure in just four days and raising fresh concerns about the stability of the country’s electricity supply.
Power generation reportedly plunged sharply from about 3,825 megawatts (MW) at 10 a.m. to as low as 39MW by 11 a.m. Earlier in the day, generation had peaked at 4,762MW around 6 a.m. before the sudden drop.
Eko Electricity Distribution Company (EkoDisCo) confirmed the development in a notice to its customers, stating that the system collapse led to a widespread power outage across its network.
“Kindly be informed that there was a system collapse at 10:48 hours, which has resulted in a loss of power supply across our network,” the company said.
EkoDisCo added that efforts were ongoing in collaboration with the Transmission Company of Nigeria (TCN) to restore power as quickly as possible.
“We are currently working with our TCN partners and hope for a speedy restoration of the grid. We will keep you updated as soon as power supply is restored. Kindly bear with us,” the statement read.
This latest incident is the second grid collapse recorded in January 2026 and the third in less than a month. The national grid had previously collapsed on December 29, 2025, and again on Friday, January 23, 2026.

At the time of Tuesday’s collapse, load allocation to all electricity distribution companies dropped to 0.00MW, indicating that no power was being supplied anywhere on the network.
The Nigerian Independent System Operator (NISO) has not yet provided a detailed explanation for the latest collapse. However, the agency confirmed that the outage occurred around 12:40 p.m. following the simultaneous tripping of several 330kV transmission lines.
Speaking on the earlier collapse recorded on Friday, NISO explained that multiple disturbances combined to shut down the entire interconnected national grid.
“The national grid experienced a system-wide disturbance, which resulted in a total outage across the interconnected network,” the operator stated.
The repeated grid failures have continued to disrupt electricity supply nationwide, sparking renewed calls for urgent reforms and infrastructure upgrades in the power sector.
