The Transmission Company of Nigeria has announced a planned six-hour power outage that will affect several communities in Ogun State as it carries out maintenance on a key transmission asset.

In a statement issued through its official X handle, TCN explained that engineers will be working on a 40MVA 132/33KV power transformer at the McPherson Transmission Substation. The facility is a critical link in the network that feeds parts of the state.

The company said the maintenance window will run from 10:00 a.m. to 4:00 p.m., during which the transformer will be shut down to allow technical teams to perform preventive routine checks and other safety procedures.

Because of the shutdown, the Ibadan Electricity Distribution Company will be unable to supply power to customers in McPherson, University and Ogunmakin and surrounding areas for the duration of the work. Homes, small businesses and institutions in these communities are expected to experience a total loss of supply.

TCN’s General Manager, Public Affairs, Ndidi Mbah, said the exercise is part of ongoing efforts to strengthen the transmission network and minimise the risk of sudden equipment failure that could lead to longer and unplanned outages.

She noted that preventive maintenance on major transformers is essential to keep them operating at optimal capacity, reduce technical losses and improve the stability of power delivered to distribution companies.

Mbah appealed to residents and business owners to make contingency plans for the six-hour interruption, urging them to switch off sensitive appliances ahead of the outage and only power them back on after supply has been fully restored.

The company apologised for the inconvenience the planned work may cause, stressing that short, scheduled interruptions are necessary to avoid more disruptive breakdowns in the future. It assured customers that supply will be restored immediately after the maintenance is completed, provided no unforeseen technical issues arise.

TCN reiterated its commitment to improving service delivery across its network and called for continued public understanding as it undertakes similar maintenance activities in other parts of the country.
