The Transmission Company of Nigeria (TCN) has declared force majeure on the Ikeja West–Osogbo 330kV transmission line after a heavy rainstorm caused the collapse of a critical tower, raising fresh concerns over the resilience of Nigeria’s power infrastructure.
The incident occurred on Thursday, April 16, 2026, when severe weather disrupted one of the key transmission corridors supplying electricity across the South-West. The development was confirmed in a statement issued by TCN’s General Manager of Public Affairs, Ndidi Mbah.
According to the company, the transmission line tripped during the storm due to a fault detected about 14.9 kilometres from the Ikeja West (Ayobo) end. Subsequent inspection revealed that Tower No. 515 had collapsed at its midsection בעקבות the intense weather conditions.
TCN said it has since activated emergency response measures, including mobilising engineers, equipment, and materials to the site to begin dismantling the damaged structure and prepare for reconstruction.
The Ikeja West–Osogbo line is a strategic backbone of Nigeria’s national grid, linking Lagos to other parts of the South-West. Any disruption along this route often leads to power supply challenges, especially in densely populated urban areas and industrial hubs.
Despite the setback, the company assured electricity consumers that alternative transmission routes remain operational and are currently being used to evacuate bulk power and minimise outages.
“We are working assiduously to restore flexibility and redundancy in the affected corridor,” the statement noted, adding that updates would be provided as repair work progresses.
By invoking force majeure, TCN indicated that the outage resulted from circumstances beyond its control, in this case, extreme weather conditions, which temporarily hinder its ability to meet full transmission obligations.
The incident highlights ongoing vulnerabilities within Nigeria’s electricity infrastructure, particularly as climate variability increases the frequency of storms and other extreme weather events.
Nigeria’s national grid, managed by TCN, continues to face challenges such as ageing infrastructure, limited capacity, and frequent system disturbances. These issues have prompted repeated calls from stakeholders for increased investment in more durable and weather-resistant transmission systems.
The Ikeja West substation remains one of the country’s most critical power hubs, making any disruption along its connected lines significant for households and businesses alike.
While restoration efforts are underway, the latest development adds to growing concerns about the stability of power supply in Nigeria and the urgent need for long-term infrastructure upgrades.
