The Transmission Company of Nigeria has announced a planned four-day power outage in parts of Ondo State and surrounding areas due to a preventive maintenance exercise at the Ife/Ondo Transmission Substation.

In a statement posted on its official X (formerly Twitter) handle on Monday, TCN said the maintenance will take place from Monday, February 2, to Thursday, February 5, 2026, between 8:00 a.m. and 3:00 p.m. daily.

According to the company, the exercise will involve work at the Ife/Ondo 330/132kV and 132/33kV Transmission Substation, and is aimed at improving the reliability and efficiency of power transmission in the region.

“The maintenance will be carried out daily between 8:00 a.m. and 3:00 p.m. and is aimed at improving the reliability of electricity transmission in the area,” the statement read.

TCN explained that its contractor would decommission an old wave trap and install a new one at the substation during the period.

In addition, the company disclosed that the project would include the replacement of single-circuit towers on the Ife/Ondo 132/33kV transmission line with new double-circuit towers, a move expected to strengthen the transmission infrastructure.

The transmission company advised electricity distribution companies and consumers in the affected areas to make adequate arrangements, assuring that normal power supply would be restored immediately after the completion of the maintenance work.
