Electricity supply disruptions affected parts of Lagos, Abuja and Ogun State on Monday after Nigeria’s power generation plunged from 3,840 megawatts (MW) at 7 a.m. to 476.70MW by 1 p.m.
Data from the Nigerian Independent System Operator (NISO) dashboard showed that generation dropped by 3,363.30MW, representing a decline of approximately 87.6 per cent within six hours.
The sharp fall, which reportedly began around 12:40 p.m., left several major power stations, including Egbin, Jebba, Shiroro and Kainji, recording zero output.
Despite the dramatic reduction, NISO reportedly dismissed claims of a national grid collapse, saying there was no system-wide disturbance. The operator indicated that technical checks would be conducted to investigate the abnormal readings.
Meanwhile, Ikeja Electric attributed reduced electricity supply across its network to a shortfall in the power allocated from the national grid.
In Abuja, the Abuja Electricity Distribution Company reported a technical fault affecting several communities, including Kado Fish Market, Life Camp Extension and Idu Karmo.
The Ibadan Electricity Distribution Company also reported transmission restrictions affecting electricity availability in parts of Ogun State, including Ota, Ifo and Abeokuta.
It remained unclear whether all the reported outages were directly linked to the sharp fall in generation. Further technical findings from the system operator are expected to clarify the cause.
