Nigeria was plunged into darkness again on Tuesday following another failure of the national power grid, the second collapse recorded within four days and the third in less than a month.

Power sector data showed that electricity generation nosedived from about 3,825 megawatts at 10 a.m. to just 39MW an hour later. Earlier on Tuesday, generation had risen to roughly 4,762MW by 6 a.m. before the sudden disruption.

Eko Electricity Distribution Company confirmed the incident, notifying customers that the system failure led to a loss of supply across its coverage areas.

“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 Disco said.

The company explained that it was working with the Transmission Company of Nigeria to restore electricity as quickly as possible. “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.

At the time of the collapse, records indicated that electricity allocation to all distribution companies dropped to 0.00MW, suggesting that no part of the country was receiving power supply during the outage.

The Nigerian Independent System Operator has not yet disclosed the specific cause of Tuesday’s grid failure but confirmed that the disruption occurred around 12:40 p.m. due to the tripping of several 330kV transmission lines.

The latest collapse adds to a growing list of recent grid failures, including incidents recorded on December 29, 2025, and Friday, January 23, 2026. Addressing the January outage, NISO said the incident resulted in a nationwide blackout.

“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.
