TCN SCHEDULES MAINTENANCE ON DELTA SUBSTATION, WARNS OF POWER DISRUPTION By Raymond Enoch

The Transmission Company of Nigeria (TCN) has announced a scheduled five-hour maintenance exercise on its Delta 132/33kV Transmission Substation, warning electricity consumers in parts of Delta State to expect temporary disruption in power supply on Tuesday, November 10, 2026.

In a notice issued on Monday, November 9, 2026, the company said its Delta Sub-Region maintenance crew would carry out annual preventive maintenance on the 132kV Ughelli/Effurun transmission line bay equipment between 10:00am and 3:00pm.

TCN explained that the exercise would affect electricity supply to several communities and locations in Delta State, as the Benin Electricity Distribution Company (BEDC) would be unable to off-take electricity for onward distribution to customers throughout the maintenance period.

The affected areas include Enerhen, Sapele, Osubi, Effurun, the Petroleum Training Institute (PTI), PSML, Refinery 1 and 2, Warri and their surrounding communities.

The company said the planned exercise was part of its routine preventive maintenance programme aimed at sustaining transmission infrastructure, improving operational reliability and reducing the risk of unexpected equipment failures.

TCN appealed to electricity consumers in the affected areas to bear with it, while expressing regret over the inconvenience the temporary interruption in power supply might cause.
