TCN: Rehabilitation of Amuwo Substation to Last 122 Days

The Transmission Company of Nigeria (TCN) has announced that rehabilitation works at its Amuwo 132/33kV Gas Insulated Substation (GIS) in Lagos will last for 122 days, as part of efforts to strengthen power supply infrastructure in the area.

In a notice issued by the Lagos Region of the company, TCN stated that the project, being handled by an Engineering, Procurement and Construction (EPC) contractor, commenced on March 18, 2026, and is expected to be completed by July 30, 2026.

The company explained that to enable the safe kick-off of the rehabilitation, a temporary power interruption was carried out on March 18 to allow for the decommissioning of the Amuwo substation. The outage affected the Apapa, Ilashe, and Atlas Cove 132/33kV substations, resulting in a brief disruption of electricity supply to customers within those areas, it said.

However, TCN, in a statement signed by the General Manager, Public Affairs, Ndidi Mbah,

clarified that power supply was restored to the affected substations later the same day after the decommissioning process was successfully concluded.

To cushion the impact of the rehabilitation on electricity consumers, the company disclosed that 40MVA and 30MVA mobile transformers have been deployed at the Amuwo Transmission Substation. 

These, it said, will enable both Eko Electricity Distribution Company (EKEDC) and Ikeja Electricity Distribution Company (IKEDC) to continue off-taking power for distribution to their customers during the project period.
