Nigeria’s electricity generation plunged sharply on Monday following multiple trippings on the national grid’s 330-kilovolt transmission network, disrupting power supply and prompting distribution companies to alert customers.
Data from the Nigerian Independent System Operator (NISO) showed that generation fell from 3,840 megawatts (MW) at 7am to 476.70MW by 1pm, a drop of about 87.6 per cent. Several power plants, including Egbin, Jebba, Shiroro and Kainji, recorded zero output during the disruption.
The Abuja Electricity Distribution Company (AEDC) said the grid-related problem had affected electricity supply to its customers, adding that technical teams were working to restore supply. Ikeja Electric also attributed reduced supply hours across its network to lower electricity allocations from the national grid.
In a statement on Monday, NISO said the incident occurred at about 12:40pm on October 19. It said it worked with the Transmission Company of Nigeria (TCN) to stabilize the system and restore normal operations.
The operator confirmed that restoration efforts had been completed, stressing that the incident affected only a section of the grid and did not amount to a nationwide grid collapse.
