TCN Announces Three-Day Power Outage in Parts of Lagos
The Transmission Company of Nigeria (TCN) has announced a three-day power disruption affecting parts of Lagos due to scheduled maintenance on the Aja/Alagbon 330 kV transmission line.
According to a notice issued on Friday, the maintenance will take place from 26 to 29 November 2025, between 8:00 a.m. and 6:00 p.m. daily. TCN spokesperson Ndidi Mbah explained that the exercise is necessary to install wave traps on the 330 kV line bays at the Aja and Alagbon Transmission Substations.
The maintenance is expected to 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.
During the maintenance, supply from Alagbon Substation will be diverted to the Ijora 132 kV line, while supplies to Akoka and Oworo Transmission Substations will be rerouted to the Ikeja West 132 kV line. TCN assured residents that brief load disruptions may occur, but power supply will generally continue during the exercise.
The company apologized for any inconvenience and said the maintenance is part of ongoing efforts to enhance the reliability and efficiency of Lagos’ electricity transmission network.
It was noted that parts of Lagos had also experienced outages in July and October 2025 due to earlier maintenance activities by TCN.
