Lagos Residents to Experience Intermittent Power Supply as TCN Begins 25-Day Maintenance

Electricity consumers across Lagos State will face intermittent power outages as the Transmission Company of Nigeria (TCN) commences a 25-day maintenance exercise on the Omotosho–Ikeja West 330kV transmission line.

In an official statement via it’s X (formerly Twitter) handle, TCN disclosed that the Nigerian Electricity Regulatory Commission (NERC) and the National Independent System Operator (NISO) have approved the critical infrastructure upgrade.

The project, scheduled to run from July 28 to August 21, between 8:00 a.m. and 5:00 p.m. daily, involves the installation of an Optical Ground Wire (OPGW) fibre cable. According to TCN’s General Manager, Public Affairs, Ndidi Mbah, “power will be restored after each day’s work, while other circuits remain operational to help maintain supply across the Lagos network.”

The upgrade, once completed, will support the full deployment of the Supervisory Control and Data Acquisition (SCADA) system—enabling real-time grid monitoring and improved management of electricity distribution.

Eko Electricity Distribution Company (EKEDC), in a public notice, confirmed the outage and urged customers to prepare for possible disruptions. “There will be a planned outage by our partner, TCN, from Monday, July 28 to Thursday, August 21, between 08:00 – 15:00 hrs daily. This is to enable safe execution of the maintenance work,” the statement read. EKEDC also noted that customers should expect intermittent outages and load shedding across its network.

Similarly, Ikeja Electric (IE) issued a notice informing customers of the TCN-led exercise and its impact. “Customers may experience irregular power supply and load shedding across our network. We sincerely regret any inconvenience caused,” the utility said.

Both distribution companies assured consumers that efforts are in place to minimise disruption and restore normalcy after each day’s maintenance window.
