Oru Leonard
The Transmission Company of Nigeria (TCN) has commenced its annual preventive maintenance of two 30MVA, 132/33kV power transformers at the Sagamu Transmission Substation in Ogun State.
The maintenance exercise, which began on Thursday, September 3, 2026, will continue on Friday, September 4, and will run for seven hours each day, from 10:00 a.m. to 5:00 p.m.
According to TCN, its maintenance crew is carrying out routine checks on the T1 and T2 transformers as part of efforts to ensure optimal performance, reliability and stability of the transmission infrastructure.
The company explained that the exercise has affected the ability of the Ibadan Electricity Distribution Company (IBEDC) to off-take electricity to some of its customers supplied through the T1 transformer, particularly customers in REAL and Sagamu.
TCN further disclosed that customers supplied through the T2 transformer will also be affected during Friday’s maintenance period. The affected areas and facilities include CEPLASS, NNPC/Ogijo, Metafrique and Babcock.
The transmission company said the temporary interruption is necessary to enable its engineers to safely conduct the scheduled maintenance and ensure the transformers remain reliable.
TCN apologised to electricity consumers in the affected areas for the inconvenience caused by the maintenance exercise, assuring that the work is part of routine measures to improve the reliability of electricity supply.
