A fire incident which occurred at the Egbin Power Plc at about 6:30 am on Tuesday, August 5, 2025, has disrupted power supply in Ikorodu and some other areas.

The Transmission Company of Nigeria (TCN) disclosed this in a statement signed by the GM, Public Affairs, Ndidi Mbah, on Thursday, with the fire affecting the company’s 1SOMVA power transformer at its Egbin Transmission Substation.

Mbah said the fire which originated from one of the power station’s service transformer owned by Egbin Power Plc, is directly connected to the 33kV side of one of TCN’s power transformer, a 1ISOMVA 330/132/33kV Inter-Bus Transformer Il.

Investigations, Mbah disclosed, traced the cause of the fire to a faulty 33kV instrument transformer (CT/VT) installed by Egbin Power Plc, which was engulfed by fire.

This ultimately led to the damage to a 1SOMVA power transformer belonging to TCN, causing oil leakage from the transformer due to a tear in its main tank.

“As a result of the incident, there is a temporary reduction in bulk power supply to Ikorodu and Odogunyan 132/33kV transmission substations, which supply the Ikeja Electricity Distribution Company (IKEDC) and Eko Electricity Distribution Company (EKEDC) for some parts of its franchise areas, as well as Sagamu Line 1, Sagamu Line 2, and Maryland Line 2 on the 132kV network within Lagos State,” Mbah said.

At the time of the incident, a total load of 47MW was affected. This load was immediately diverted to the second available 150MVA power transformer within the substation, which is now operating under strain.

Since then, the capacity deficit has increased and remains high, resulting in load-shedding across all affected areas.

Mbah pleaded with the public to bear with the TCN as its operatives work diligently to replace the damaged transformer and restore normal power supply as soon as possible.

He explained that the TCN has already notified IKEDC and IBEDC to assist in load management within their franchise areas.

“On our part, TCN is already making urgent arrangements to source the replacement transformer,” Mbah stated.

“We sincerely apologize for the inconvenience this is causing the two distribution companies and electricity customers in the affected areas and pledge to work hard to ensure full restoration of bulk supply to the substations in the shortest possible time.”
