The Transmission Company of Nigeria, TCN, has declared force majeure on the Ikeja West–Osogbo 330kV line following a violent rainstorm that affected a key power tower.
Force majeure is a contractual clause freeing parties from liability when an unforeseen, uncontrollable event, such as natural disaster, war, or pandemic happened making it impossible for parties to fulfil obligations.
The Ikeja West–Osogbo 330kV line, according to energy analysts, is very strategic in the sense that it links Nigeria’s commercial hub, Lagos and other south west states to the National Grid.
The rainstorm, according to the TCN happened on Thursday, April 16, 2026, affected one of the major transmission corridors responsible for evacuating bulk electricity across parts of the South-West.
According to a statement issued on Sunday by TCN General Manager, Ndidi Mb the transmission line tripped during the storm due to a fault traced to a specific section of the network.
“The Transmission Company of Nigeria 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 line tripped during the storm due to a fault, which was detected at approximately 14.9 kilometres from the Ikeja West (Ayobo) end of the transmission line.”
The TCN said the damage was discovered after a detailed inspection by its maintenance team, which revealed that the transmission towers along the route had suffered a structural failure, adding that efforts are ongoing by the engineers to “dismantle” the affected towers.
“Further inspection by TCN maintenance crews revealed that Tower No. 515 had collapsed during the storm, with the structure giving way at its midsection. While TCN is mobilising materials and personnel for the re-erection of the fallen tower, Efforts are currently ongoing by its engineers to dismantle the affected tower,” TCN said.
