Egbin Fire Outbreak Causes 47MW Power Loss — TCN

The Transmission Company of Nigeria (TCN) has confirmed that a fire outbreak at the Egbin Power Plant in Lagos has led to the loss of 47 megawatts (MW) of power, temporarily disrupting electricity supply to several parts of Lagos and Ogun States.

In a statement signed by its General Manager, Public Affairs, Ndidi Mbah, on Wednesday night, TCN said the incident occurred at about 6:30 a.m. on Monday, following a fire that originated from one of the power station’s service transformers owned by Egbin Power Plc.

The transformer, according to the company, is directly connected to the 33kV side of TCN’s 150MVA 330/132/33kV Inter-Bus Transformer II located at the Egbin Transmission Substation.

Preliminary investigations, TCN said, traced the cause of the fire to a faulty 33kV instrument transformer, either a current transformer (CT) or voltage transformer (VT) installed by Egbin Power Plc.

It stated that the equipment was reportedly engulfed by fire, which spread and damaged TCN’s 150MVA power transformer, resulting in significant oil leakage due to a tear in the transformer’s main tank.

“The Transmission Company of Nigeria (TCN) wishes to inform the public that a fire incident occurred at the Egbin Power Plc at about 6:30 am on August 5, 2025, affecting TCN’s 150MVA power transformer at its Egbin Transmission Substation.

“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 150MVA 330/132/33kV Inter-Bus Transformer II.

“Investigations 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 damage to a 150MVA 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 IKEDC and IBEDC 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.

“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”, the company stated.

TCN, however, apologised for the inconvenience the development might have caused the two distribution companies and electricity customers in the affected areas.

It pledged to work hard to ensure full restoration of the bulk supply to the substations in the shortest possible time.

“We sincerely apologise 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.

“Please bear with us as we work diligently to replace the damaged transformer and restore normal power supply as soon as possible.

“TCN has already notified the IKEDC and EKEDC to assist in load management within their franchise areas. On our part, TCN is already making urgent arrangements to source the replacement transformer”, the company stated.
