TCN Blames Apo-Karu Blackout On Cut Jumper at Tower T2, Begins Repairs

The Transmission Company of Nigeria (TCN) has blamed Monday’s blackout in Karu, Nyanya, Mararaba and other adjoining communities on a cut jumper on the yellow phase at Tower T2 of the Apo–Karu 132kV transmission line, saying repairs began on Tuesday to restore supply.

The TCN said the line tripped at 5:31 pm on Monday, October 12, 2026, resulting in the loss of bulk electricity supply to the Karu Transmission Substation.

Following the trip, the company said its engineers carried out a physical inspection of the transmission line and traced the fault to a cut jumper on the yellow phase at Tower T2.

A jumper is a connecting conductor on a transmission tower that links sections of the line and helps transmit electricity between towers. Damage to such a component can interrupt the flow of power along the affected line.

TCN said its maintenance crew was scheduled to carry out urgent repairs on Tuesday, October 13, 2026, to restore the Apo–Karu line to service.

The company, however, did not state the expected time of completion or give a definite restoration time for electricity supply to affected areas.

As a result of the outage, the Abuja Electricity Distribution Company (AEDC) said it was unable to supply power to customers in Karu, Nyanya, Kugbo, Jikwoyi, Kurudu, Orozo, Karshi, Mararaba and adjoining communities.

The affected areas cut across parts of the Federal Capital Territory and Nasarawa State, including densely populated residential districts and communities along the Abuja–Keffi corridor.

TCN apologised to electricity consumers in the affected areas for the inconvenience caused by the outage.
