The Transmission Company of Nigeria (TCN) has confirmed a fire incident that occurred at Egbin Power Plc around 6:30 a.m. on Wednesday, August 5, 2025. According to TCN, the outbreak affected its 150 MVA power transformer located at the Egbin Transmission Substation.
TCN’s General Manager of Public Affairs, Mrs. Ndidi Mbah, who confirmed the development in a statement, said the fire originated from one of the power station’s service transformers owned by Egbin Power Plc and directly connected to the 33 kV side of one of TCN’s power transformers—a 150 MVA 330/132/33 kV Inter-Bus Transformer II.
According to her, investigations traced the cause of the fire to a faulty 33 kV instrument transformer (CT/VT) installed by Egbin Power Plc, which was engulfed by fire, leading to damage to a 150 MVA 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,” he described.
She confirmed that 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.“
Mrs Mbah appealed for patience as work to replace the damaged transformer and restore normal power supply is underway 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.”
“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.“
