The Transmission Company of Nigeria (TCN) said a fire incident occurred at the Egbin Power Plc at about 6:30 a.m. on Tuesday, affecting TCN’s 150MVA power transformer at its Egbin transmission substation.
The TCN General Manager, Public Affairs, Ndidi Mbah, in a statement on Wednesday evening said the fire, which originated from one of the power station’s service transformers 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.
“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 statement said.
Ms Mbah said 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, she said, ultimately led to the damage of 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, she added that there is a temporary reduction in bulk power supply to Ikorodu and Odogunyan 132/33KV transmission substations, which supply Ikeja Electricity Distribution Company (IKEDC) and Ibadan Electricity Distribution Company (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, Ms Mbah said, a total load of 47MW was affected.
She explained that this load was immediately diverted to the second available 150MVA power transformer within the substation, which is now operating under strain.
Since then, she said, the capacity deficit has increased and remains high, resulting in load-shedding across all affected areas.

“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 Eko Electricity Distribution Company (EKEDC) to assist in load management within their franchise areas. On our part, TCN is already making urgent arrangements to source the replacement transformer.
“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,” she said.
