Electricity supply to customers connected to the 33kV feeders at the Keffi and Akwanga Transmission Substations has been disrupted following the collapse of three transmission towers along the Karu-Keffi-Akwanga 132kV transmission line corridor.
The Transmission Company of Nigeria (TCN) disclosed this in a statement signed by its management on Thursday, saying towers T78, T79 and T80 collapsed during heavy rain and windy conditions.
According to the company, the incident occurred at about 4:06 p.m. on Wednesday, October 7, 2026, when the 132kV Karu-Keffi-Akwanga Single Circuit Transmission Line tripped on overcurrent relay protection.
TCN said investigations conducted after the trip confirmed the collapse of the three transmission towers, prompting the company to immediately isolate the affected section of the network as a safety measure.
The collapse has rendered all 33kV outgoing feeders at the 132/33kV Keffi and 132/33kV Akwanga Transmission Substations unavailable.
TCN said no load can currently be nominated on the affected feeders until the transmission infrastructure is restored.
The development is expected to affect electricity customers receiving supply through the affected substations, with the transmission company expressing regret over the disruption.
TCN said its engineers are already at the affected location assessing the extent of the damage and determining the materials, equipment and other requirements needed to commence restoration work.

The company said the assessment would guide the repair and reconstruction process, adding that it was making every effort to restore bulk power supply as quickly as possible.
“Please bear with us as we make every effort to ensure that necessary repairs are completed as quickly as possible to enable the restoration of bulk power supply,” the company said.
TCN also assured electricity consumers that it would continue to provide updates as restoration efforts progress.
The incident highlights the vulnerability of critical electricity transmission infrastructure to extreme weather conditions, coming at a time when the country continues to grapple with challenges affecting the reliability of the national power grid.
