The Transmission Company of Nigeria (TCN) has commenced a two-day annual preventive maintenance exercise on two 30MVA power transformers at its Sagamu Transmission Substation in Ogun State.
The exercise, which began on Thursday, September 3, 2026, will continue on Friday, September 4, and is scheduled to take place for seven hours each day, from 10:00 a.m. to 5:00 p.m.
In a statement, TCN said its maintenance crew is working on the T1 and T2 30MVA, 132/33kV power transformers as part of routine checks aimed at ensuring optimal performance and reliability of the equipment.
The company said the exercise has affected the ability of the Ibadan Electricity Distribution Company (IBEDC) to off-take electricity to some customers supplied through the T1 transformer, including consumers in REAL and Sagamu.
It added that customers supplied through the T2 transformer, including CEPLASS, NNPC/Ogijo, Metafrique and Babcock, would also be affected during the maintenance period on Friday.
TCN apologised to electricity consumers in the affected areas for the inconvenience caused by the exercise, stressing that the maintenance is necessary to improve the reliability of power supply.
