The Transmission Company of Nigeria has announced a planned six-hour power outage affecting several communities in Ogun State on Thursday, May 14, 2026.
According to a statement released on the company’s official X handle, the outage is due to scheduled maintenance on the 40MVA 132/33KV power transformer at the McPherson Transmission Substation.
The maintenance exercise is scheduled to take place between 10:00 a.m. and 4:00 p.m. as engineers carry out preventive routine checks aimed at ensuring the continued efficiency and reliability of the transformer.
As a result of the exercise, the Ibadan Electricity Distribution Company will be unable to supply electricity to customers in McPherson, University and Ogunmakin areas during the maintenance period.
The Transmission Company of Nigeria stated that the planned maintenance is necessary to improve service delivery and reduce the risk of unexpected faults on the transmission network.
The General Manager, Public Affairs of TCN, Ndidi Mbah, explained that the exercise forms part of efforts to maintain optimal transformer performance and strengthen electricity supply reliability.
“The maintenance exercise is to enable TCN crew to undertake preventive routine checks on the transformer to ensure continued optimal performance. Consequently, Ibadan Electricity Distribution Company (IBEDC) will be unable to supply electricity to its customers in McPherson, University, and Ogunmakin during the period of the maintenance,” she said.
The company apologised to residents and businesses that would be affected by the temporary interruption and appealed for understanding while the maintenance work is completed.
Nigeria’s power sector has continued to face challenges linked to ageing infrastructure, grid instability and transmission constraints, prompting routine maintenance exercises by operators to minimise faults and improve network performance across the country.
