TCN Announces Three-Day Power Outage in Lagos: Here Are What Residents Need to Know

The Transmission Company of Nigeria has announced a fresh three-day electricity disruption in parts of Lagos.

The agency said the electricity disruption is due to its planned maintenance of the Ala/Alagbon 330 kV transmission line from November 26th to 29th November 2025.

TCN’s spokesperson, Ndidi Mbah, disclosed this in a notice on Friday.

The schedule will affect electricity distribution to Eko Electricity Distribution Company coverage in Lagos South and part of Ogun State, including Ojo, Festac, Ijora, Mushin (also Orile areas), Apapa, Lekki (also Ibeju areas), Lagos Island (also Ajele areas) 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 exercise is to enable the TCN contractor to install wave traps on the 330kV line bays at the Aja and Alagbon Transmission Substations in Lagos State. During this period, supply from the Alagbon Substation will be diverted to the Ijora 132kV line, while supplies to the Akoka and Oworo Transmission Substations will be diverted to the Ikeja West 132kV line.

“TCN explains that there will be a brief load disruption due to the diversion on the affected lines, but the areas will continue to receive a normal power supply during the maintenance window.

“TCN regrets any inconvenience this may cause electricity consumers within the Eko Disco franchise and appeals for understanding, noting that the exercise is part of ongoing efforts to improve the reliability and efficiency of transmission infrastructure in Lagos State,” TCN stated.

In July and October this year, parts of Lagos were thrown into darkness over TCN’s maintenance exercises.
