TCN Announces Power Outage in Ibadan over Maintenance at Ayede Substation

The Transmission Company of Nigeria (TCN) has announced a planned power outage in parts of Ibadan, Oyo State, due to a scheduled maintenance exercise at its Ayede Transmission Substation.

In a statement issued on Tuesday, the General Manager, Public Affairs, TCN, Ndidi Mbah, said the maintenance would be carried out on one of the company’s 100MVA 132/33kV transformers.

She stated that the exercise would take place between 10:00 a.m. and 6:00 p.m. on May 5, 2026.

According to the statement, the maintenance is part of TCN’s routine preventive programme aimed at ensuring the continued efficiency and reliability of critical power infrastructure within the national grid.

“The Transmission Company of Nigeria hereby notifies the public of scheduled maintenance of one of its 100MVA 132/33kV power transformers at the Ayede Transmission Substation,” the statement read in part.

Mbah explained that the maintenance would enable TCN engineers to carry out necessary checks and servicing of the transformer to maintain optimal performance and prevent unexpected system failures.

As a result of the exercise, the Ibadan Electricity Distribution Company will be unable to supply electricity to some of its customers during the period.

The affected areas include Express, Industrial and Oluyole, where residents and businesses are expected to experience temporary power outages for the duration of the maintenance.

Industry observers note that such preventive maintenance exercises are critical to reducing the risk of unplanned outages, equipment failure and grid instability, which have continued to challenge Nigeria’s power sector.

They added that while scheduled outages may cause short-term inconvenience, they are necessary to safeguard long-term system reliability and improve electricity supply.

Residents in the affected areas have, however, continued to express concerns over frequent power disruptions, calling on operators in the electricity value chain to minimise downtime and improve service delivery.

Efforts to improve grid performance have remained a priority for TCN, which is responsible for bulk electricity transmission across the country.

The company has in recent years intensified maintenance and upgrade activities across its substations as part of broader efforts to strengthen the national grid and reduce system disturbances.

Mbah assured that the outage would be strictly limited to the duration of the maintenance and that power supply would be restored immediately after the work is completed.

She also appealed to customers in the affected areas to bear with the company, noting that the exercise is in the overall interest of ensuring a more stable and reliable electricity supply.

“TCN apologises for any inconvenience this may cause electricity consumers in the affected areas,” she added.

The development comes amid ongoing efforts by stakeholders in Nigeria’s power sector to address infrastructure gaps and improve service delivery to consumers.
