TCN Announces Major Power Outage in Lagos

The Transmission Company of Nigeria (TCN) has announced that parts of Lagos, including Lekki, Ikoyi, and Jakande, will experience a four-day power outage.

In a statement posted on X on Wednesday, TCN’s spokesperson, Ndidi Mbah, revealed that the blackout will occur on October 11, 12, 18, and 19, 2025. Each interruption is expected to last for about eight hours daily.

TCN explained that the planned outage is necessary to carry out preventive maintenance on key transmission lines — specifically, the Ajah/Lekki 330 kV line on October 11, and the Ajah/Alagbon 330 kV line on October 12, 18, and 19, 2025.

“The maintenance on the Ajah/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 Ajah/Alagbon and Ajah/Lekki 330 kV transmission lines.

“Consequently, there will be an 8-hour outage from 10:00 AM to 6:00 PM on the Ajah/Lekki 330 kV line on October 11, 2025, and on the Ajah/Alagbon 330 kV line on October 12, 18, and 19, 2025.

“We apologise for any inconvenience this may cause electricity customers in Lekki, Ikoyi, Jakande, and surrounding areas during this period,” TCN stated.
