TCN Announces Four-Month Power Interruption for Lagos Substation Rehabilitation
The Transmission Company of Nigeria (TCN) has issued a formal apology to residents and businesses in Lagos State while announcing a planned four-month power interruption. This significant disruption is necessary to facilitate major rehabilitation work on the critical Amuwo 132/33kV Gas Insulated Substation (GIS), a key component of the region's electricity infrastructure.
Project Timeline and Affected Areas
The extensive rehabilitation project is scheduled to span 122 days, running from March 18 to July 30, 2026. According to TCN's General Manager of Public Affairs, Ndidi Mbah, the initial phase required a temporary power interruption on March 18 to safely decommission the Amuwo substation. This outage impacted several important substations including Apapa, Ilashe, and Atlas Cove, resulting in short-term power cuts throughout surrounding areas.
"The outage was necessary to ensure safety during the initial phase of the project. Power has since been restored to the affected substations," Mbah confirmed in an official statement released over the weekend.
Mitigation Measures Implemented
To minimize the impact of this prolonged rehabilitation work, TCN has deployed strategic measures to maintain partial electricity supply. The company has installed 40MVA and 30MVA mobile transformers at the Amuwo Transmission Substation, enabling both Eko Electricity Distribution Company (EKEDC) and Ikeja Electricity Distribution Company (IKEDC) to continue supplying electricity to their customers throughout the project period.
"This is to ensure that electricity consumers still receive supply, even though it may not be at full capacity," the TCN statement noted, emphasizing that this arrangement is specifically designed to avoid a complete blackout during the four-month rehabilitation period.
Long-Term Benefits and Infrastructure Modernization
The rehabilitation of the Amuwo substation represents a crucial component of TCN's broader efforts to modernize Nigeria's transmission infrastructure and improve overall grid efficiency. Gas-insulated substations like Amuwo are particularly important in urban power networks, offering superior reliability and reduced maintenance requirements compared to conventional systems.
Once completed in July 2026, the upgraded facility is expected to deliver substantial improvements in power stability, reduce frequency of outages, and better support the growing electricity demand in Lagos, Nigeria's primary commercial hub and most populous city.
Resident Cooperation and Additional Power Challenges
While acknowledging the significant inconvenience this project will cause, TCN has emphasized that the long-term benefits outweigh the temporary challenges. The company has urged residents and businesses in affected areas to exercise patience as work progresses, assuring that all necessary steps are being taken to minimize disruption.
"TCN sincerely apologizes for the inconvenience this project may cause and appreciates the understanding and cooperation of electricity consumers," the statement added.
This announcement comes alongside separate power challenges in Lagos, as Eko Electricity Distribution Company recently alerted residents about significant outages affecting multiple areas due to a fiery incident along the Lekki-Epe Expressway. That disruption resulted from a vehicle collision with a stationary gas tanker that caused severe damage to critical electricity infrastructure.
Technical teams from both TCN and distribution companies continue working to address these various power challenges while implementing the substantial infrastructure improvements that promise enhanced electricity reliability for Lagos residents in the coming years.
