Three transmission towers have collapsed along the Karu-Keffi-Akwanga 132kV transmission line in Nasarawa State, disrupting bulk electricity supply to 33kV feeders serving parts of Keffi and Akwanga.
The Transmission Company of Nigeria (TCN) disclosed this in a statement on Thursday, saying the incident occurred at about 4:06pm on Wednesday, October 7, during rainy and windy conditions.
Collapse of Transmission Towers Affects 33kV Feeders at Keffi and Akwanga Substations
The Transmission Company of Nigeria (TCN) hereby informs the public that all 33kV outgoing feeders at the 132/33kV Keffi and 132/33kV Akwanga Transmission Substations are currently unavailable following the collapse of Towers T78, T79 and T80 along the Karu-Keffi-Akwanga 132kV Transmission Line corridor.
At about 1606hrs yesterday, Wednesday, 7th October 2026, during rainy and windy conditions, the 132kV Karu-Keffi-Akwanga Single Circuit Transmission Line tripped on overcurrent relay protection. Investigations revealed that three transmission towers have collapsed. TCN promptly isolated for safety.
Consequently, all 33kV outgoing feeders at the Keffi and Akwanga Transmission Substations are presently unavailable. No load can therefore be nominated on the affected feeders on the interim.
TCN engineers are currently on site, to assess the extent of the damage to enable them determine requirements needed to commence restoration activities.
The Company regrets the inconvenience this development will cause electricity customers taking supply from substations affected by the tower incident.
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.
Kindly note that we will continue to provide further updates as restoration efforts progress.

According to the company, the 132kV Karu-Keffi-Akwanga Single Circuit Transmission Line initially tripped on overcurrent relay protection before investigations revealed the collapse of Towers T78, T79 and T80 along the line corridor.
TCN said it subsequently isolated the affected line as a safety measure, leaving all 33kV outgoing feeders at the 132/33kV Keffi and 132/33kV Akwanga transmission substations unavailable.
The statement read, “The Transmission Company of Nigeria hereby informs the public that all 33kV outgoing feeders at the 132/33kV Keffi and 132/33kV Akwanga Transmission Substations are currently unavailable following the collapse of Towers T78, T79 and T80 along the Karu-Keffi-Akwanga 132kV Transmission Line corridor.
“At about 1606hrs yesterday, Wednesday, 7th October 2026, during rainy and windy conditions, the 132kV Karu-Keffi-Akwanga Single Circuit Transmission Line tripped on overcurrent relay protection.
“Investigations revealed that three transmission towers have collapsed. TCN promptly isolated for safety,” the company said.
The disruption means electricity distribution companies cannot nominate load on the affected feeders until the damaged transmission infrastructure is repaired and bulk power supply is restored.
The company said its engineers had been deployed to the affected location to assess the extent of the damage and determine the materials and other requirements needed to begin restoration work.
TCN did not give a specific timeline for restoring electricity supply, explaining that the duration would depend on the outcome of the technical assessment and the repairs required.
The incident has affected a critical part of the transmission network linking bulk electricity supply to distribution feeders serving communities in the area.
TCN apologised to customers affected by the disruption and said it was working to complete the necessary repairs and restore bulk power supply as quickly as possible.
“The Company regrets the inconvenience this development will cause electricity customers taking supply from substations affected by the tower incident,” it said.
“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 also assured affected customers that further updates would be provided as restoration efforts progress.
