Lagos State and its environs may face a prolonged blackout following the sudden shutdown of the Egbin Power Station, Nigeria’s largest electricity‑generating plant on the national grid.
Power system operators say the station, located in Ikorodu, suffered a major operational disturbance that led to a total loss of generation, dropping from about 641 megawatts to zero output at around 8:21 p.m. on April 28.
The Nigerian Independent System Operator (NISO) and the national grid operator said the incident was triggered by a failure of the plant’s central compressor and a malfunction of the circulating water pump system, necessitating an immediate shutdown of all generating units to prevent further damage and ensure facility safety.
The shutdown has drastically reduced available power generation nationwide, with Lagos being one of the most affected areas because of its high electricity demand and heavy dependence on grid‑supplied power.
The situation has been compounded by the earlier forced outage of the Osogbo–Ikeja West 330 kilovolt transmission line, which has further restricted the evacuation of available electricity into the Lagos load centre.
Transmission Company of Nigeria (TCN) had earlier declared a force majeure on the Ikeja West–Osogbo line after it was damaged by a severe rainstorm, leaving repair work ongoing and limiting the network’s ability to move power into the commercial hub.
Grid officials said consumers, especially in Lagos and surrounding communities, should expect extended outages and possible load‑shedding until the plant is repaired and the transmission constraint is resolved.
They also urged households and businesses to rely on backup systems while assuring that all relevant stakeholders are working to restore normal supply as quickly as possible.
