TCN Announces Seven-Hour Power Outage in Iwo for Maintenance

The Transmission Company of Nigeria (TCN) has announced a planned seven-hour power outage in parts of Osun State following scheduled maintenance on a power transformer at the Iwo Transmission Substation.

TCN, in a notice issued by its Osogbo Region, said routine annual maintenance would be carried out on the 40MVA 132/33kV transformer at the substation on Thursday, June 4, 2026, between 10:00am and 5:00pm.

The company said the exercise forms part of its ongoing efforts to enhance the reliability and efficient operation of the national transmission network.

As a result of the maintenance work, the Ibadan Electricity Distribution Company (IBEDC) will be unable to receive power supply from the transmission station during the period.

Consequently, electricity consumers in Iwo Town, Bowen University and Rabbish will experience a temporary outage lasting seven hours.

TCN apologised to affected customers for the inconvenience and assured the public that normal electricity supply would be restored immediately after the maintenance exercise is completed.
