The national power grid collapsed again on Tuesday, marking the second incident in four days.
Wizopa reports that electricity generation fell sharply to just 39 megawatts at 11 a.m., from 3,825 MW recorded at 10 a.m.
Our team tracking the development reported that power generation had earlier reached a peak of 4,762 MW as of 6 a.m. on Tuesday.
In addition, EkoDisCo, in a statement issued on Tuesday, notified its customers of a system collapse that led to a loss of power supply.
“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,” it said.
“This is the second grid collapse in January 2026 and the third in less than one month. The national grid had earlier collapsed on December 29, 2025, and more recently on Friday, January 23, 2026.
When the grid collapsed on Tuesday, load allocation to the distribution companies stood at 0.00 MW, showing that no Disco was supplying electricity at the time of the incident.
The Nigerian Independent System Operator is yet to provide an explanation for the cause of the latest grid collapse.
NISO confirmed that the outage happened at about 12:40 p.m., after the simultaneous tripping of several 330kV transmission lines.
Reacting to Friday’s grid collapse, NISO stated in a release that the combined incidents led to 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.
