Nigeria restores electricity to Lagos after grid outage

A widespread power outage caused by a national grid disturbance left large parts of Lagos and surrounding areas without electricity on Thursday, June 25. The Transmission Company of Nigeria has since restored one of two critical transmission lines, partially returning bulk power supply to the affected region.

The incident occurred at approximately 8:19 a.m. when the national grid experienced voltage instability that rapidly spread across the Lagos transmission corridor. This instability led to the loss of several generating stations and caused outages on key transmission lines, interrupting electricity supply to Lagos and its environs. In response, the National Control Centre instructed multiple generating stations to reduce their output to arrest a frequency rise and stabilize the system.

The Minister of Power, Joseph Tegbe, convened an emergency meeting with the heads of TCN and the Nigerian Independent System Operator to coordinate urgent restoration efforts. By Thursday, TCN announced it had successfully restored the Benin-Egbin 330kV transmission line, which is now transmitting bulk electricity. However, work continues to fully rectify the Benin-Omotoso 330kV transmission...
