Transmission Company of Nigeria (TCN) has disclosed its plan to commence maintenance of Omotosho-Ikeja West 330kv power line which will result in 25-day intermittent blackout for electricity consumers in Lagos State.
TCN in a statement on its ‘X’ handle said Nigerian Electricity Regulatory Commission (NERC) and National Independent System Operator (NISO) ‘’have approved the critical infrastructure upgrade.”
“The upgrade involves the installation of Optical Ground Wire (OPGW) fibre cable on the Omotosho/Ikeja West 330kV transmission line, scheduled from July 28 to August 21, from 8am to 5 pm,” TCN said in a statement by its General Manager, Public Affairs, Ndidi Mbah.
“Power will be restored through the line after each day’s work; all other circuits will remain operational to ensure a stable power supply to the Lagos complex during the exercise.”
Upon completion, TCN said the upgrade would enable full operationalisation of the supervisory control and data acquisition (SCADA) system, enhancing real-time monitoring and management of the grid.
In a terse statement to its customers, Eko Electricity Distribution Company (EKEDC) said: “Kindly be informed that there will be a planned outage by our partner, Transmission Company of Nigeria (TCN), from Monday, 28th July to Thursday 21st August, 2025 between 08:00- 15:00 hrs daily. This is to enable work to be safely carried out on the Omotosho/Ikeja West 330kV powerline.”
While apologising for the inconvenience this may cause, the utility said the impact would result in intermittent outage and load shedding across its network.
Similarly, Ikeja Electric (IE), in a notice signed by its management to its customers, said: “Please be informed that Transmission Company of Nigeria (TCN) will carry out scheduled maintenance on the Omotosho-Ikeja West 330kV transmission line from Monday July 28 to Thursday August 21, 2025, between the hours of 8am and 5pm daily.
“During this period, customers may experience intermittent power supply and load shedding across our network due to the planned TCN outage. We sincerely regret any inconvenience this may cause.”
