Outages Hit Parts of Nigeria as Power Generation Crashes from 3,840MW to 476.70MW
Electricity outages affected parts of Nigeria on Monday after power generation plunged from approximately 3,840 megawatts (MW) at 7 a.m. to 476.70MW by 1 p.m., according to data from the Nigerian Independent System Operator (NISO).
The sharp decline, which began around 12:40 p.m., wiped out more than 3,363MW of generation within hours, leaving several major power plants, including Egbin, Jebba, Shiroro and Kainji, recording zero output on the grid.
The disruption affected electricity supply in parts of Lagos, Abuja and Ogun State, with consumers experiencing outages and reduced hours of power supply.
Ikeja Electric attributed reduced supply across its network to a shortfall in electricity allocated from the national grid. The Abuja Electricity Distribution Company also reported a technical fault affecting some communities, while restrictions on parts of the transmission network were reported in Ogun State.
Despite the dramatic fall in generation, NISO reportedly dismissed claims of a national grid collapse, saying there was no evidence of a system-wide disturbance. The operator indicated that equipment tripping or localised technical issues could be involved and said its technical team would investigate the abnormalities.
The incident has renewed concerns about the reliability of Nigeria’s electricity supply, which depends on the performance of generating plants and the transmission and distribution networks.
The cause of the sharp generation decline had not been conclusively established in the reports available on Monday afternoon. Further updates are expected as the grid operator investigates the incident and electricity supply conditions evolve.
