The Transmission Company of Nigeria (TCN) has announced that a fire incident at the Egbin Power Plc has affected its 150MVA power transformer at the Egbin Transmission Substation.
The incident which occurred at about 6:30 am on August 5, 2025, originated from one of the power station’s service transformer owned by Egbin Power Plc and directly connected to the 33kV side of one of TCN’s power transformer- a 150MVA 330/132/33kV Inter-Bus Transformer II.
TCN, in a statement by its General Manager, Public Affairs, Ndidi Mbah said that investigations traced the cause of the fire to a faulty 33kV instrument transformer (CT/VT) installed by Egbin Power Plc, causing oil leakage due to tear on the main tank of a 150MVA power transformer belonging to TCN.
According to the statement, “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.”
TCN further explained 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.”
The Company appealed that “ 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.
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.”
