Residents and businesses in Lagos and surrounding areas may face significant power disruptions starting Monday, July 28, as the Transmission Company of Nigeria (TCN) embarks on scheduled maintenance of the Omotosho–Ikeja West 330kV transmission line.
In a public notice issued on Friday, July 25, TCN announced that the maintenance will take place daily from 8:00 am to 5:00 pm lasting until Thursday, August 21, 2025.
The company warned of intermittent power supply and load shedding, stating:
“Customers may experience intermittent power supply and load shedding across our network due to the planned TCN outage.”
Although the notice did not specify which areas would be directly affected, the Omotosho–Ikeja West line is a critical supply route for much of Lagos and nearby regions, raising fears of widespread instability in electricity supply during the maintenance period.
TCN acknowledged the expected inconvenience, noting that the maintenance is essential for strengthening the performance and reliability of the national grid.
“We regret the inconvenience this may cause and appeal for customers’ understanding as we carry out this necessary upgrade,” the company said.
