The power outage affecting Lagos State has worsened following confirmation from the Transmission Company of Nigeria (TCN) that a recent fire incident at the Egbin Power Station has impacted its substation.

In a statement issued on Thursday, TCN spokesperson Ndidi Mbah revealed that the fire broke out on Tuesday, August 5, 2025, at approximately 6:30 a.m.
She explained that the blaze damaged a 150 megavolt-amperes (MVA) power transformer, resulting in an oil leak caused by a tear in the transformer’s main tank.
She noted that the incident has led to a reduction in bulk power supply to the Ikorodu and Odogunyan 132/33 kilovolt transmission substations, which supply Ikeja Electricity Distribution Company and Ibadan DisCo for some parts of its franchise areas, as well as Sagamu Line 1, Sagamu Line 2, and Maryland Line 2 on the 132 kilovolt network within Lagos State.
“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. This ultimately led to the damage of 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 132/33 kV transmission substations, which supply IKEDC and IBEDC for some parts of their franchise areas, as well as Sagamu Line 1, Sagamu Line 2, and Maryland Line 2 on the 132 kV network within Lagos State.
“At the time of the incident, a total load of 47 MW was affected. This load was immediately diverted to the second available 150 MVA 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.
“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.”
The development comes as Ikeja and Eko DisCo announced a 21-day blackout in Lagos State from July 28 to August 21, 2025.
