TCN restores Alaoji-Owerri 132KV Transmission lines

The Transmission Company of Nigeria (TCN) has announced the restoration of the Alaoji–Owerri 132kV Transmission Lines 1 and 2, which tripped on Tuesday, June 23, 2026.

According to TCN, its maintenance crew identified the fault location and mobilised to the site to commence repair work. Both lines were successfully energised at 7:05 p.m. and 7:06 p.m., respectively, on Wednesday, June 24, 2026.

A release signed by TCN’s General Manager of Public Affairs, Ndidi Mbah, and provided to Tribune Online, stated that after successfully repairing the fault on Line 1, that line was restored to service at approximately 7:25 p.m. on Tuesday, June 23, 2026.

This restoration enabled a partial resumption of bulk electricity transmission to Imo State, Bayelsa State (Yenagoa), and parts of Rivers State (Ahoada).

“To facilitate the safe repair of Line 2, it became necessary to temporarily de-energise Line 1. This was because the close proximity of the two high-voltage transmission lines could induce electromagnetic induction on the faulty line when the adjacent line remained energised, thereby posing a safety risk to TCN ‘s maintenance engineers.

“The temporary outage of Line 1 was approved by the Nigerian Independent System Operator (NISO) and undertaken with the concurrence of the Enugu Electricity Distribution Company (EEDC) and the Port Harcourt Electricity Distribution Company (PHEDC). This precautionary measure provided the safe working space required for TCN engineers to complete repairs and restore Line 2 to service.

“With the successful restoration of both transmission lines, the Alaoji–Owerri transmission corridor is now fully operational. EEDC and PHEDC can now offtake full load for onward distribution to their customers,” the statement read.

While appreciating the patience and understanding of electricity consumers affected by the outage and regrets the inconvenience caused, the Company said it remained committed to maintaining a reliable and efficient transmission network for the evacuation and delivery of bulk electricity across the country.
