The Transmission Company of Nigeria (TCN) has clarified that the power outage recorded on Wednesday at 11:34 AM was caused by the tripping of the Omotosho-Ikeja West 330kV transmission line, not a total grid collapse as widely reported.
In a statement, TCN’s General Manager for Public Affairs, Ndidi Mbah, explained that at the time of the incident, the Benin-Egbin 330kV transmission line was undergoing scheduled maintenance.
The resulting outage affected the power supply to Lagos, Abuja, and Osogbo while the rest of the grid remained stable.
She further confirmed that the transmission line had been restored, and the electricity supply was back to normal in the affected areas.
“TCN remains committed to ensuring efficient bulk power transmission across the country and is implementing measures to strengthen grid stability,” Mbah stated.
Data from the Independent System Operator (ISO) showed a sharp drop in electricity supply on Wednesday, declining from an average of 4,064.70 megawatts around 11 AM to 1,222.78 MW by noon.
The Abuja Electricity Distribution Company (AEDC) also acknowledged the incident, stating that the power supply to its franchise areas was disrupted at 11:38 AM.
In a message shared via its official X account, AEDC assured customers that efforts were underway to restore electricity fully as soon as the grid stabilized.
“We appreciate your patience and understanding as we work with relevant stakeholders to restore normal power supply,” the statement read.
