Transmission Company of Nigeria ,TCN, has confirmed the loss of 165 megawatts ,MW, of electricity following an incident on the Ikeja-West/Osogbo 330 kV transmission line.
The disruption, which occurred on Wednesday, April 2, 2025, at approximately 9:22 pm, was caused by severe windy rainfall and a trailer truck accident that resulted in the collapse of a transmission tower.
A statement issued in Abuja yesterday by the TCN’s Public Affairs Manager, Ndidi Mbah, said the fault was traced to a location about 14.9 kilometres from the Ikeja-West Transmission Substation.
The company stated further that investigations revealed that Tower 528 collapsed after a trailer truck struck detached conductors on Tower 527, leading to extensive structural damage.
Also, Towers 526 and 524 were affected.
