The national power grid suffered another collapse on Tuesday, marking the second incident in four days.
Reports showed that power generation dropped sharply to 39 megawatts at 11 a.m., from 3,825 MW as of 10 a.m.
Generation had earlier peaked at 4,762 MW around 6 a.m. on Tuesday.
Meanwhile, Eko Electricity Distribution Company, in a statement on Tuesday, informed its customers that a system collapse had resulted in power loss.
“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 marked the second grid collapse in January 2026 and the third within less than one month. The national grid had previously collapsed on December 29, 2025, and more recently on Friday, January 23, 2026.
As the time of Tuesday’s collapse, load allocation to the distribution companies was 0.00 MW, indicating that no Disco was supplying power at the time of the incident.
The Nigerian Independent System Operator is yet to give a detailed explanation for the latest incident.
However, NISO confirmed that the outage occurred at about 12:40 p.m., following the simultaneous tripping of several 330kV transmission lines.
Reacting to Friday’s grid collapse, NISO had said in a statement 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.
