The Transmission Company of Nigeria (TCN) has confirmed that the fire incident which occurred at the Egbin Power Plc at about6:30 am on August 5, 2025, affected its 150MVA power transformer.
TCN’s General Manager, Mrs. Ndidi Mbah who confirmed the development in a statement on Wednesday, said the fire which originated from one of the power station’s service transformers owned by Egbin Power Plc, was directly connected to the 33kV side of one of TCN’s power transformer- a 150MVA330/132/33kV Inter-Bus Transformer II.
According to her, 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. Which ultimately led to the damage to a 150MVA power transformer belonging to TCN, causing oil leakage from the transformer due to a tear in its main tank.
She explained that 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.
Mrs. Mbah informed that at the time of the incident, a total load of 47MW was affected. But 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.
The GM appealed for patience as the company works diligently to replace the damaged transformer and restore normal power supply as soon as possible.
She said the TCN had already notified the IKEDC and EKEDC to assist in load management within their franchise areas. Adding that on the company’s part, it is already making urgent arrangements to source for the replacement of the transformer.
TCN apologized for the inconvenience the incident is causing the two distribution companies and electricity customers in the affected areas and pledged to work hard to ensure full restoration of bulk supply to the substations in the shortest possible time.
