Data monitored by The PUNCH showed that power generation plunged sharply from 3,825 megawatts (MW) at 10 a.m. to just 39MW by 11 a.m.

Earlier in the day, generation had peaked at 4,762MW around 6 a.m.

The development triggered a nationwide blackout, with load allocation to all distribution companies dropping to 0.00MW, indicating that no Disco was supplying electricity at the time of the collapse.

Confirming the outage, Eko Electricity Distribution Company (EkoDisCo) informed customers that a system collapse occurred at 10:48 a.m., leading to loss of power across its network.

“Kindly be informed that there was a system collapse at 10:48hrs, which has resulted in a loss of power supply across our network,” EkoDisCo said. “We are currently working with our TCN partners as we hope for the speedy restoration of the grid.”

The Nigerian Independent System Operator (NISO) has yet to explain the specific cause of Tuesday’s collapse. However, it confirmed that the outage followed the simultaneous tripping of several 330kV transmission lines.

The latest incident follows previous grid collapses on December 29, 2025, and Friday, January 23, 2026, raising fresh concerns over the stability of Nigeria’s power infrastructure.

Reacting to Friday’s outage, NISO had said the disturbance resulted in a total collapse of the interconnected national grid, leaving the entire country without electricity supply.
