Nigeria’s national power grid suffered another collapse on Tuesday, marking the second system failure in four days and the third in less than one month.
Findings showed that electricity generation plunged sharply from about 3,825 megawatts 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. before the sudden drop.
Following the incident, electricity supply was cut across the country as load allocation to all distribution companies fell to 0.00MW, indicating a total blackout at the time of the collapse.
Eko Electricity Distribution Company confirmed the development in a statement to customers, explaining that a system collapse occurred at 10:48 a.m., resulting in a loss of power supply across its network.
The Disco said it was working with the Transmission Company of Nigeria and other stakeholders to ensure quick restoration of supply, assuring customers that updates would be provided as the situation improved.
Meanwhile, the Nigerian Independent System Operator has yet to give details on the cause of Tuesday’s collapse. However, NISO confirmed that the outage occurred around 12:40 p.m. following the simultaneous tripping of several 330kV transmission lines.
The latest incident comes days after the grid collapsed on Friday, January 23, 2026, and follows a similar nationwide outage recorded on December 29, 2025, highlighting persistent instability in the country’s power infrastructure.
