The Transmission Company of Nigeria (TCN) has restored the 330kV Kainji-Birnin Kebbi Single Circuit Transmission Line to service after it was taken offline following the collapse of a transmission tower in Yauri, Kebbi State.

According to TCN, the line was successfully returned to service at 5:24 p.m. on Thursday, October 1, 2026, bringing an end to the prolonged outage that began after Tower T367 collapsed on September 7.

The company said the restoration was achieved through the installation of an Emergency Restoration System (ERS) tower at the site of the collapsed structure.

The repair process involved dismantling and decommissioning the damaged tower, aligning and preparing the transmission conductors and skywire, installing the temporary ERS structure and completing the associated works required to safely reconnect the line.

TCN said its engineers and technical personnel worked continuously to complete the restoration and return the transmission infrastructure to operation as quickly and safely as possible.

The collapse had forced TCN to take the line out of service and affected bulk electricity transmission along the Kainji-Birnin Kebbi corridor. In an earlier statement issued after the incident, TCN said the tower was discovered to have collapsed during a fault investigation following repeated trips on the line. Preliminary findings pointed to heavy winds and rainstorms in the area as the cause of the structural failure.

TCN subsequently began rehabilitation work at the affected location in Yauri. By September 24, the company reported that the collapsed tower had been completely dismantled and that the conductors and skywire had been aligned in preparation for the next stage. The ERS tower had also been moved to the site ahead of installation.

The Kainji-Birnin Kebbi line is an important part of Nigeria's high-voltage transmission infrastructure, linking the Kainji axis with Birnin Kebbi and supporting electricity transmission towards parts of the North-West. TCN has previously identified the Kainji-Birnin Kebbi corridor as part of broader efforts to strengthen transmission capacity in the region.

The restoration is expected to improve the availability of transmission capacity along the affected corridor. However, the return of the transmission line does not automatically guarantee uninterrupted electricity for consumers, as electricity supply also depends on available generation, transmission conditions elsewhere on the grid and the state of distribution infrastructure.

TCN thanked electricity consumers and other stakeholders in the affected areas for their patience and understanding throughout the period of the outage.

The company also reaffirmed its commitment to maintaining and strengthening Nigeria's electricity transmission network and responding to faults and damage to critical infrastructure as quickly as possible.
