TCN Restores Benin–Omotosho 330kV Transmission Line After Week-Long Outage

July 3 () — The Transmission Company of Nigeria (TCN) has restored the Benin–Omotosho 330kV transmission line to service, bringing to an end a week-long outage that constrained electricity supply to parts of Lagos, Edo, and neighbouring states served by major distribution companies.

The company announced on Friday that the high-voltage transmission line was successfully re-energised at 7:05 p.m. on Thursday, July 2, 2026, following the completion of emergency repairs and maintenance by its engineers.

In a statement signed by its General Manager, Public Affairs, Ndidi Mbah, TCN said the outage began on June 25, 2026, after conductors on the transmission line became detached, disrupting the evacuation of electricity through one of the country’s strategic power corridors.

According to the company, its engineers immediately mobilised to the site, restrung the affected conductors, and carried out comprehensive maintenance on the damaged sections before restoring the line to service.

“The restoration followed an outage on the line on June 25, 2026, caused by the detachment of conductors. TCN engineers have since worked to restring and complete maintenance on the affected sections of the transmission line,” the statement said.

TCN explained that with the transmission infrastructure now fully operational, electricity distribution companies connected to the line would be able to draw increased power from the national grid for distribution to consumers.

The beneficiaries include the Benin Electricity Distribution Company (BEDC), Eko Electricity Distribution Plc (Eko DisCo), and Ikeja Electric, all of which had experienced reduced bulk power allocation during the period of the outage.

The restoration is expected to improve electricity supply across their franchise areas, particularly in parts of Lagos and Edo states, where consumers had experienced supply constraints linked to the transmission disruption.

The development also marks the completion of TCN’s efforts to restore the Benin transmission corridor after the June 25 incident. While the Benin–Egbin 330kV line had earlier been returned to service, repairs on the Benin–Omotosho line continued until Thursday’s successful energisation.

TCN apologised to customers for the inconvenience occasioned by the outage and thanked electricity consumers and stakeholders for their patience and understanding throughout the repair period.

The company reiterated its commitment to strengthening the reliability of the national transmission network through prompt maintenance and swift response to infrastructure faults, to support improved power delivery to distribution companies and end-users across the country.
