The Transmission Company of Nigeria (TCN) has announced that it will carry out scheduled maintenance on the Aja–Alagbon 330kV transmission line in Lagos from November 26 to 29, 2025. The work will take place daily between 8:00 a.m. and 6:00 p.m.
According to TCN, the maintenance exercise will enable contractors to install wave traps on the 330kV line bays at both the Aja and Alagbon Transmission Substations. The company said the installation is part of ongoing efforts to enhance grid reliability and improve transmission efficiency.
During the four-day operation, electricity supply from the Alagbon Substation will be diverted to the Ijora 132kV line. Similarly, supply to the Akoka and Oworo Transmission Substations will be routed through the Ikeja West 132kV line.
TCN stated that these diversions will result in temporary load reductions and brief supply disruptions within the affected areas during the maintenance window. The company assured consumers that the interruption is necessary to ensure long-term network stability.
The statement added that TCN regrets any inconvenience experienced by electricity customers within the Eko Disco franchise and appealed for public understanding. It emphasized that the maintenance is part of broader upgrades designed to strengthen Lagos State’s transmission infrastructure.
