The Transmission Company of Nigeria (TCN) will conduct preventive maintenance on the Aja/Lekki 330kV transmission line on October 11, 2025, and on the Aja/Alagbon 330kV line on October 12, 18, and 19, 2025, respectively.
The maintenance on the Aja/Lekki 330kV line will enable TCN’s contractor to install a transformer protective system on the 300MVA 330/132/33kV power transformer at the Alagbon Transmission Substation.
Additionally, TCN’s maintenance crew will replace corroded insulators on critical towers of the Aja/Alagbon and Aja/Lekki 330kV transmission lines.
During the maintenance period, power supply to Alagbon Transmission Substation will be diverted to the Ijora 132kV line, while Akoka and Oworo Transmission Substation supplies will be rerouted to the Ikeja-West 132kV line.
Consequently, there will be an 8-hour outage from 10:00 AM to 6:00 PM on the Aja/Lekki 330kV line on October 11, 2025, and on the Aja/Alagbon 330kV line on October 12, 18, and 19, 2025.
We apologize for any inconvenience this may cause electricity customers in Lekki, Ikoyi, Jakande, and surrounding areas during this period.
