The Transmission Company of Nigeria (TCN) has restored bulk power supply to its Katampe 330kV Transmission Substation through the Gwagwalada–Katampe 330kV Line 1.
The restoration was completed at 4:15 p.m. on Friday, October 9, 2026, following an earlier disruption of supply through the Shiroro–Katampe 330kV Line 1, which remains out of service due to a fault.
In a statement signed by TCN Management on Friday, the company disclosed that the planned maintenance on the Gwagwalada–Katampe 330kV Line 1 had been suspended to allow the line to continue supplying the Katampe Transmission Substation.
The maintenance work was scheduled to involve the replacement of defective line isolators and the associated earthing switch.
TCN explained that suspending the maintenance was necessary to ensure continued power supply to the substation while the Shiroro–Katampe line remains unavailable.
The company apologised to electricity consumers in the affected areas for any inconvenience caused by the disruption and subsequent adjustments to its maintenance schedule.
