The Transmission Company of Nigeria (TCN) has declared a force majeure on the Ikeja West–Osogbo 330kV transmission line following a severe rainstorm that damaged critical infrastructure along the corridor.
In a statement on Sunday signed by Ndidi Mbah, General Manager, Public Affairs, TCN said the incident occurred on Thursday, 2026, when the line tripped during the storm due to a fault detected about 14.9 kilometres from the Ikeja West (Ayobo) end of the line.
“Further inspection by TCN maintenance crews revealed that Tower No. 515 had collapsed during the storm, with the structure giving way at its midsection,” the company said.
The development has temporarily disrupted optimal power transmission along the route, a key artery in the national grid linking the southwestern axis.
TCN said it has commenced emergency response measures, including the mobilization of materials and personnel to restore the damaged infrastructure.
“While TCN is mobilizing materials and personnel for the re-erection of the fallen tower, efforts are currently ongoing by its engineers to dismantle the affected tower,” the statement added.
The company, however, reassured electricity consumers that contingency arrangements are in place to limit the impact of the outage.
“We assure that we will work assiduously to restore flexibility and redundancy in that corridor as alternative line is still in service evacuating bulk power. Updates will be provided as work progresses,” TCN said.
