The Transmission Company of Nigeria (TCN) has confirmed a fire incident at the Egbin Power Plc facility in the early hours of Tuesday, August 5, 2025, affecting power supply in parts of Lagos and Ogun States.
According to a statement issued by TCN on Thursday, the fire broke out at approximately 6:30 am and damaged one of the company’s key transmission assets: a 150MVA, 330/132/33kV Inter-Bus Transformer II located at the Egbin Transmission Substation.
It noted that preliminary investigations revealed that the fire originated from a faulty 33kV current or voltage transformer (CT/VT) owned by Egbin Power Plc.
The defective equipment was connected to the 33kV side of TCN’s transformer, resulting in significant damage to the main tank of the transformer, including oil leakage and a tear in the structure.
As a result, power supply has been temporarily reduced to several critical transmission lines and substations, including the Ikorodu and Odogunyan 132/33kV substations, as well as Sagamu Lines 1 and 2, and Maryland Line 2. An estimated 47 megawatts of load was initially affected and has since been redirected to the station’s second 150MVA transformer, which is now operating under increased strain.
Business Post reports that this development has led to power deficits and load-shedding in the affected areas.
The distribution companies, Ikeja Electric (IKEDC) and Eko Electricity Distribution Company (EKEDC), have been officially notified and are managing electricity loads within their respective franchise areas.
TCN said urgent efforts are underway to source and install a replacement transformer to restore normal operations.
“We sincerely apologize for the inconvenience and assure all affected customers that we are working hard to restore normal power supply as quickly as possible,” the company stated.
