The Transmission Company of Nigeria (TCN) has announced a scheduled maintenance exercise at its Sagamu Transmission Substation, which will temporarily disrupt electricity supply to parts of Sagamu and surrounding areas in Ogun State.
The seven hour daily maintenance, which began on Thursday, September 3, 2026, will continue today, Friday, September 4, from 10:00 a.m. to 5:00 p.m.
According to TCN, its maintenance crew is carrying out annual preventive maintenance on the T1 and T2 30MVA, 132/33kV power transformers at the substation.
The exercise is aimed at conducting routine checks on the transformers to ensure optimal performance and improve the reliability of electricity supply.
TCN said the maintenance has affected the ability of the Ibadan Electricity Distribution Company (IBEDC) to off take electricity to customers supplied through the T1 transformer, including consumers in REAL and Sagamu.
Customers supplied through the T2 transformer including CEPLASS, NNPC/Ogijo, Metafrique and Babcock will also experience the disruption during Friday’s maintenance period.
TCN apologised to electricity consumers in the affected areas for the inconvenience caused by the exercise.
