Nigeria’s grid electricity supply plunged by 81.5 per cent to 675 megawatts on Monday afternoon, following a sharp decline in power generation that triggered supply constraints across distribution networks.
Data from the Nigerian Independent System Operator showed that electricity generation fell from 3,647MW at noon to 675MW by 1pm, representing a loss of 2,972MW within one hour.
The number of power plants supplying the national grid also declined, with Azura, Egbin, Jebba and Kainji among the plants reported to have gone offline.
Electricity supply had peaked at 4,458MW by 6am before dropping to 3,647MW at noon and plunging further at 1pm.
Supply later recovered to 2,150MW by 5pm, although it remained significantly below the morning level.
The development prompted electricity distribution companies, including Abuja Electricity Distribution Company and Ikeja Electric, to notify customers of reduced supply caused by challenges on the national grid.
AEDC said the Transmission Company of Nigeria’s technical team was working to restore grid stability, adding that electricity supply was gradually returning to its feeders.
Ikeja Electric, meanwhile, attributed the reduced supply across its network to a shortfall in the electricity allocated to it from the national grid.
The company said it was engaging relevant stakeholders to improve available supply while distributing the electricity received as efficiently and equitably as possible.
