TCN said Towers T78, T79 and T80 collapsed at about 4:06pm on Wednesday, October 7, 2026, during rainy and windy conditions, causing the 132kV Karu-Keffi-Akwanga Single Circuit Transmission Line to trip on overcurrent relay protection.
The Company further stated that investigations conducted after the trip confirmed that the three transmission towers had collapsed, prompting engineers to isolate the affected section 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.
“The incident has rendered all 33kV outgoing feeders at the 132/33kV Keffi and 132/33kV Akwanga Transmission Substations unavailable”, TCN said.
It explained that no load could be nominated on the affected feeders until the situation was addressed, potentially affecting electricity customers supplied through the two substations.
The Company said its engineers were already at the site assessing the extent of the damage and determining the materials and other requirements needed to commence restoration work.
