The Transmission Company of Nigeria (TCN) has announced it plans to embark on a 3-day maintenance in Lagos.
The scheduled electricity disruption will take place in parts of Lagos for the maintenance of the Aja/Alagbon 330 kV transmission line.
The maintenance is scheduled from 26 to 29 November 2025, the company confirmed in a notice released on Friday.
TCN’s spokesperson, Ndidi Mbah, stated that the maintenance will impact areas under the Eko Electricity Distribution Company, as well as parts of Ogun State, including Ojo, Festac, Ijora, Mushin (including Orile), Apapa, Lekki (including Ibeju), Lagos Island (including Ajele), and Agbara.
“The Transmission Company of Nigeria (TCN) wishes to inform the public that scheduled maintenance will be carried out on the Aja/Alagbon 330 kV transmission line from November 26 to 29, 2025, between 8:00 a.m. and 6:00 p.m. daily,” the notice read.
The exercise will involve the installation of wave traps on the 330 kV line bays at the Aja and Alagbon Transmission Substations. During this period, supply from Alagbon Substation will be diverted to the Ijora 132 kV line, while supplies to Akoka and Oworo Transmission Substations will be redirected to the Ikeja West 132 kV line.
TCN reassured consumers that while brief load disruptions may occur due to the diversions, normal power supply will continue during the maintenance window.
The company apologised for any inconvenience, emphasizing that the exercise is part of ongoing efforts to improve the reliability and efficiency of transmission infrastructure in Lagos State.
It was noted that some parts of Lagos experienced similar outages in July and October 2025 due to earlier maintenance activities by TCN.
