The Transmission Company of Nigeria TCN has stated that the Alaoji–Owerri 132kV Transmission Lines 1 and 2 have been successfully restored to service.  A statement made available to the media yesterday in Abuja said that the two lines were energized at 7:05 p.m. and 7:06 p.m., respectively, Wednesday, 24th June 2026.

The statement signed by the Company’s General Manager  GM Public Affairs, Ndidi Mbah explained that the transmission lines tripped on Tuesday, 23rd June 2026, however,  upon identification of the fault location, the maintenance crew immediately mobilized to the site and commenced repair works.

Following the successful repair of the fault on Line 1, the line was restored to service at approximately 7:25 p.m. on Tuesday, 23rd June 2026, enabling partial restoration of bulk electricity transmission to Imo State, Bayelsa State Yenagoa, and parts of Rivers State Ahoda.

Mbah further explained that it became necessary to temporarily de-energize Line 1 in order to facilitate the safe repair of Line 2. 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 energized, 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.” She added.
