The Transmission Company of Nigeria (TCN) has announced a six-hour planned power outage in parts of Abuja on Wednesday, September 23, 2026, to enable engineers carry out annual preventive maintenance at the Central Area GIS 132/33kV Transmission Substation.
The maintenance exercise, scheduled for 10:00am to 4:00pm, will involve routine preventive checks on a 100MVA power transformer and its associated switchgear at the transmission substation.
In a statement signed by the management of TCN and dated September 23, the company said the exercise was necessary to enable its engineers undertake routine preventive checks on the transformer and associated equipment.
Consequently, the Abuja Electricity Distribution Company (AEDC) will be unable to offtake electricity supply to customers in Wuse Zones 1–7, Sheraton Hotel, the Central Business District, Utako, Jabi and adjoining areas during the maintenance exercise.
TCN apologised to electricity consumers in the affected areas for the inconvenience the planned outage may cause, while stressing that the exercise was part of its routine preventive maintenance programme.
