The Transmission Company of Nigeria (TCN) has announced a scheduled maintenance exercise at its 330kV Katampe Transmission Substation, which will result in temporary power outages in parts of Abuja and neighbouring communities.
The maintenance work, scheduled for November 14 to 24, 2026, involves the replacement of a defective earth switch on the 330kV Gwagwalada–Katampe Line 1 Incomer Disconnector.
TCN, however, said electricity supply would be interrupted only on Saturday, November 14, and Tuesday, November 24, between 10:00am and 6:00pm on both days.
The company explained that the exercise would affect the ability of the Abuja Electricity Distribution Company (AEDC) to receive bulk electricity for distribution to customers supplied through three transmission substations.
The affected areas include parts of Kubwa, Bwari and Dei-Dei, supplied through the 132kV Kubwa Substation; Zuba, Kaduna Road, Dakwa and Sabon Wuse, served by the 132kV Suleja Substation; as well as parts of Gwarinpa and Dawaki, supplied through the 132kV Gwarinpa GIS Substation.
TCN apologised to electricity consumers in the affected communities for the inconvenience the temporary power interruption would cause.
The company said the maintenance was necessary to replace the defective equipment at the Katampe substation.
