TCN Announces Four-day Blackout in Lagos

The Transmission Company of Nigeria announced a four-day blackout in Lekki, Ikoyi, Jakande, and surrounding parts of Lagos State.

The outage, which is expected to take effect on October 11, 12, 18, and 19, 2025, would last for eight hours daily.

According to TCN, the planned outage is due to preventive maintenance of its Ajah/Lekki 330 kV transmission line on October 11, 2025, and on the Ajah/Alagbon 330 kV line on October 12, 18, and 19, 2025, respectively.

“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.
