The Transmission Company of Nigeria has restored the Benin-Egbin 330kV transmission line following a power system disturbance that disrupted electricity supply across Lagos and its environs on Thursday morning.
TCN disclosed that the line, which was opened during the incident, has been successfully restored and is currently transmitting bulk electricity. However, engineers are still working to rectify faults on the Benin-Omotosho 330kV transmission line for full restoration.
The disruption occurred at approximately 8:19 a.m. on June 25, 2026, when the national grid experienced voltage instability that rapidly spread across the Lagos corridor. The incident resulted in the loss of some generating stations and widespread interruption.
Minister of Power Chief Joseph Tegbe convened an emergency meeting with TCN and NISO to coordinate urgent restoration efforts. TCN expressed regret over the inconvenience caused.
