Nigeria’s electrical supply suffered another severe blow on Tuesday, when the national power grid crashed for the second time in four days, knocking off power across the country.

Data from power sector monitoring revealed that load allocation to all energy distribution companies dropped to 0.00 megawatts, implying that no power was supplied to consumers throughout the incident.

The collapse occurred when electricity generation, which had been steadily increasing earlier in the day, abruptly dropped.

At 6 a.m., generation peaked at 4,762MW, then decreased to 3,825MW by 10 a.m. and finally to 39MW by 11 a.m.

Eko Electricity Distribution Company informed customers about the outage, which was caused by a system breakdown on the national grid.

“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. 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,” the Disco stated.

Meanwhile, the Nigerian Independent System Operator verified that the outage happened about 12:40 p.m., due to the simultaneous tripping of several 330kV transmission lines.

However, the EPA has yet to release information on what caused the latest fall.

The incident is the second grid failure in January 2026, and the third in less than a month, following previous collapses on December 29, 2025 and January 23, 2026.

Reacting to Friday’s incident, read what NISO had said below;

“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 frequent outages have raised concerns about the stability and reliability of Nigeria’s electrical system.
