Residents of Lagos State and parts of Ogun State are set to experience a major disruption in electricity supply as the Transmission Company of Nigeria (TCN) begins a 25-day scheduled maintenance project. Beginning on Monday, July 28, 2025, power will be cut off daily from 8:00 am to 5:00 pm, affecting homes, businesses, and essential services across the affected areas.
According to the Association of Nigerian Electricity Distributors (ANED), the Lagos, Ogun power outage is due to critical infrastructure upgrades being executed by TCN on the Omotosho–Ikeja West 330kV transmission line. The maintenance is scheduled to last until August 21, 2025.
Speaking on a television broadcast, ANED’s Chief Executive Officer, Mr. Sunday Oduntan, confirmed that the daily outages would impact the entire Lagos State and key areas in Ogun State including Sagamu, Ogijo, and Abeokuta. He stressed that the maintenance work, although inconvenient, is necessary for long-term stability and efficiency of the national power grid.
“The outage is a result of a technical upgrade involving the installation of Optical Ground Wire (OPGW) fibre cable,” Oduntan explained. “For safety reasons, the system will be shut down daily during the work window.”
The TCN in its own statement revealed that both the Nigerian Electricity Regulatory Commission (NERC) and the Nigeria Independent System Operator had approved the maintenance. The upgrade is targeted at improving the Supervisory Control and Data Acquisition (SCADA) system, which enables real-time monitoring and management of electricity flow across the country.
In separate public notices, the Ikeja Electric and Eko Electricity Distribution Companies confirmed the temporary outage, apologizing to customers in advance and noting that there will be “intermittent power supply and load shedding” throughout the duration of the project.
The Ikeja Electric said in a public announcement, “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.”
Similarly, the Eko Electricity Distribution Company (EKEDC) informed its customers that the power cuts were necessary “to enable works to be safely carried out” on the affected transmission line.
Hope for Stable Power Post-Upgrade
TCN has reassured the public that once the upgrade is completed, the transmission line will be equipped to support full operationalisation of the SCADA system. This would enhance grid monitoring, enable faster response times, and ultimately contribute to a more stable electricity supply in the long run.
“While the disruption is regrettable, the project will ultimately improve the reliability and efficiency of electricity supply to Lagos and Ogun states,” TCN added.
Residents, however, have expressed concerns about the impact of the outage on small businesses, healthcare facilities, and day-to-day productivity. Many are calling for improved communication and backup power solutions to cushion the effect of the prolonged blackout.
Despite these concerns, ANED’s Oduntan has urged citizens to cooperate with the authorities, noting that efforts are being made to minimize inconvenience and restore full service as swiftly as possible.
As Nigeria continues to grapple with its electricity challenges, this latest development underscores the ongoing need for sustained investment in power infrastructure and transparent coordination among stakeholders.
While the nine-hour daily outage presents temporary hardship, officials insist it is a step toward modernizing Nigeria’s power grid. Lagos and Ogun residents are advised to make contingency plans and stay informed through updates from DisCos and TCN.
