Nigeria’s national power grid collapsed again on Tuesday.
This is the second time in four days.
Power generation dropped to just 39 megawatts at 11am, down from 3,825 MW as of 10am.
Our team monitoring the situation reported that power generation had peaked at 4,762 MW as of 6am on Tuesday.
This is the second grid collapse in January 2026 and the third in less than one month. The national grid previously collapsed on December 29, 2025, and more recently on Friday, January 23, 2026.
As the grid collapsed on Tuesday, load allocation to the distribution companies was 0.00 MW, indicating that no Disco was supplying electricity at the time of the incident.
The Nigerian Independent System Operator has yet to explain the cause of the current grid collapse.
NISO confirmed that the outage occurred at about 12:40 p.m., following the simultaneous tripping of several 330kV transmission lines.
