The Nigerian Independent System Operator (NISO) has rejected reports that the country’s electricity grid suffered a nationwide collapse on Monday, October 19, 2026, attributing the disruption to a partial system disturbance.
According to the operator, the incident began at approximately 12:40 p.m. following trappings on the 330-kilovolt transmission network. Power generation subsequently fell from about 3,840 megawatts to 476.70 megawatts by 1:00 p.m., affecting electricity supply.
Several major generating stations, including Egbin, Jebba, Shiroro and Kainji, temporarily recorded zero output. However, Odukpani, Omotosho and Sapele continued generating electricity during the disturbance.
NISO said the incident did not amount to a complete grid failure, explaining that parts of the system remained operational despite the significant reduction in generation.
The operator reported that swift technical interventions restored normal operations. Recovery efforts involving NISO and the Transmission Company of Nigeria focused on stabilizing the affected transmission lines and returning the system to normal service.
Meanwhile, the government plans to develop regional grid networks as part of efforts to strengthen electricity infrastructure and reduce the impact of future disruptions.
