The Transmission Company of Nigeria (TCN) has said a severe rainstorm led to the collapse of one of its transmission towers along the Ikeja West–Osogbo 330 kilovolt line in Lagos.
The incident, which occurred on April 16, was described by the company as a force majeure event.
In a statement issued on Sunday, the General Manager, Public Affairs, Ndidi Mbah, said the development was caused by extreme weather conditions beyond the company’s control.
“The Transmission Company of Nigeria (TCN) wishes to inform the public that a force majeure has occurred on the Ikeja West–Osogbo 330kV transmission line following a severe rainstorm on Thursday, 16 April 2026,” the statement read.
Force majeure refers to unforeseen events such as natural disasters that prevent organisations from fulfilling contractual obligations, often shielding them from liability.
Mbah explained that the transmission line tripped during the storm after a fault was detected along the corridor.
“The line tripped during the storm, due to fault, which was detected at approximately 14.9km from the Ikeja West (Ayobo) end of the transmission line,” she said.
Further inspection by maintenance teams revealed that Tower 515 collapsed during the storm.
According to the spokesperson, the tower failed at its midsection, leading to the disruption on the line.
TCN said it has begun mobilising materials and personnel to re-erect the damaged tower.
Engineers are already on site working to dismantle the collapsed structure as part of efforts to restore the line.
Despite the disruption, the company assured that measures have been put in place to minimise the impact on the electricity supply. Mbah noted that efforts were ongoing to maintain flexibility and redundancy along the corridor, adding that an alternative transmission line remains operational to evacuate bulk power.
The company assured the public that it would continue to provide updates as repair works progress, even as it works to restore full capacity on the affected transmission route.
