Nigeria’s electricity generation dropped sharply from 3,840 megawatts (MW) to 476.7MW on Monday, October 19, 2026, following a disruption on the national electricity grid that affected power supply in parts of the country.
Data from the Nigerian Independent System Operator (NISO) showed that generation began falling at about 12:40 p.m., with several power plants recording zero output during the incident.
The affected plants included Egbin, Jebba, Shiroro and Kainji, while only a handful of generating stations continued supplying electricity to the grid.
The decline left some electricity consumers experiencing outages and reduced supply. Ikeja Electric attributed the reduced hours of electricity across its network to a shortfall in the power allocated to it from the national grid.
In a statement, the electricity distribution company apologised for the inconvenience and said it was engaging relevant stakeholders to improve supply.
However, NISO clarified that the incident was not a complete national grid collapse. The operator said multiple trips on the 330-kilovolt transmission network affected only a section of the grid.
NISO added that it worked with the Transmission Company of Nigeria to stabilise the system and restore normal operations.
The incident has renewed concerns about the reliability of electricity supply in Nigeria, where homes and businesses depend on the national grid for their daily activities.
