The Transmission Company of Nigeria (TCN) has declared a force majeure on the strategic Ikeja West–Osogbo 330kV transmission line after a severe rainstorm on Thursday, 16 April caused Tower No. 515 to collapse.
Force majeure describes an unforeseen event beyond one’s control that prevents a party from meeting its obligations.
The development is raising fresh concerns about the vulnerability of the national grid to extreme weather and may have political repercussions as Nigeria prepares for the 2027 general elections. President Bola Ahmed Tinubu, who campaigned in 2022 promising to fix Nigeria’s chronic power crisis and who tied much of his re‑election case to delivering on that pledge, now faces the prospect that even nature may be conspiring to frustrate those efforts.
TCN said the line tripped during the storm after a fault was detected about 14.9 kilometres from the Ikeja West (Ayobo) end.
A detailed inspection by maintenance crews found the tower had given way at its midsection; engineers are dismantling the damaged structure while materials and personnel are being mobilised to re‑erect it.
The company added that an alternative line remains in service to evacuate bulk power and that emergency measures have been activated to minimise disruption.
The Ikeja West–Osogbo corridor is a backbone of the grid, linking Lagos to other parts of the South‑West. Faults there frequently ripple into large urban centres, compounding supply instability amid long‑standing capacity and ageing‑infrastructure challenges.
Analysts say such weather‑related failures underline the urgent need for investments in weather‑resilient transmission assets.
The TCN has pledged updates as repair work progresses.
“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.
