A fire incident at Egbin Power Plc has damaged a critical transformer belonging to the Transmission Company of Nigeria (TCN), resulting in widespread power supply disruption across parts of Lagos and Ogun states. According to a press statement issued by TCN's General Manager, Public Affairs, Ndidi Mbah, on Thursday, the fire broke out at about 6:30 a.m. on August 5, 2025, affecting the company’s 150MVA power transformer at the 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,” the statement read. Investigations have traced the cause of the incident to a faulty 33kV instrument transformer (CT/VT) installed by Egbin Power Plc, which caught fire and ultimately damaged the TCN transformer. The resulting damage caused oil to leak from the transformer following a tear in its main tank. As a result, there has been 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 noted that a total load of 47MW was affected at the time of the fire, which was immediately redirected to a second 150MVA transformer at the station, now operating under significant strain. “Since then, the capacity deficit has increased and remains high, resulting in load-shedding across all affected areas,” the statement added. Efforts are underway to replace the damaged transformer and restore full service. “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,” Mbah said. The company also extended apologies to electricity customers in the affected areas. “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,” TCN stated
