The Transmission Company of Nigeria has declared force majeure on the 330kV Kainji-Birnin Kebbi transmission line following the collapse of a transmission tower situated along the corridor.

TCN, in a statement issued on Tuesday, disclosed that the line tripped at 10:44 p.m. on Monday, September 7, 2026.

The company said a trial re-closure was attempted at 11:07 p.m., but the line tripped once more, prompting linesmen from TCN’s Birnin Kebbi Sub-Region to embark on a fault-finding patrol along the transmission corridor.

TCN stated that the team discovered on Tuesday that Tower T367 had collapsed.

“Preliminary findings indicate that the collapse of the tower was caused by heavy winds and rainstorms experienced in the area,” TCN said.

The collapse has disrupted the transmission of bulk electricity through the 330kV Kainji-Birnin Kebbi corridor.

As a result, TCN declared force majeure on the affected transmission line, identified as 2KNJ-BRK1, citing the natural disaster responsible for the damage.

The company said it had begun arrangements to mobilise personnel, equipment and other resources to the affected site in order to rehabilitate the collapsed tower and restore the line to service.

Meanwhile, TCN disclosed that it had sustained electricity transmission to Sokoto by enabling the Talata Mafara-Sokoto corridor to receive supply through an alternative transmission route from the Kaduna-Mando axis.

According to the company, the alternative route makes use of the 132kV Zaria-Funtua-Gusau transmission line.

TCN said the alternative arrangement was helping to sustain power supply to the affected area while efforts continued toward restoring the damaged transmission infrastructure.

The company expressed regret over the inconvenience the incident might cause electricity consumers and other stakeholders.

It assured members of the public that it was making every effort to restore normal bulk power transmission along the affected corridor as swiftly as possible.
