Residents across Lagos and Osun states woke to extended blackouts this week after separate failures knocked out three major transmission lines, crippling electricity supply to dozens of communities across both states.

The Eko Electricity Distribution Company confirmed that its network allocation had been cut following the simultaneous outage of the Oshogbo-Ikeja 330kV transmission line and the Benin-Egbin 330kV transmission line. The DisCo said some business units were already experiencing load shedding as a direct result.
In a public notice to customers, EKEDC stated: “Osogbo/Ikeja 330kV line down. The Benin/Egbin 330kV line is down. Impact: Reduction in grid allocation.”
The company said it had opened communication lines with the national grid operator and would restore supply once the affected transmission infrastructure was returned to service. No timeline was given for restoration.
Lagos Transmission Failures Compound Flood Damage at Key Substations
The latest outages arrived on the back of disruptions that began last week when the Transmission Company of Nigeria declared force majeure on two Lagos substations, the Oworonshoki 132/33kV and the Lekki 330/132kV facilities, after severe flooding submerged both sites.
EKEDC had already warned customers that restoration at those substations depended entirely on the physical condition of the infrastructure, which engineers were still working to assess and repair.
The combined effect has left large sections of Lagos without stable electricity supply. Affected communities in the Lekki corridor include Chevy View Estate, Chevron Drive, Agungi, Alpha Beach, Ikate, Elegushi, Carlton Gate, Kusenla, Victory Park Estate, Oniru, Maroko, Muri Okunola, Ajose Adeogun, and Ligali Ayorinde, among others.
Additional areas without power include Morinho Drive, Landmark Road, Igbo Efon, Lekki Tollgate 2, Igbokusu, Gbangbala, Platinum Way, Jakande/Coastal Road, and Osapa London.
Residents in Festac, Lekki, and Agbara also reported prolonged outages by the time this report was filed. One Festac resident, Isi Okwuadi, posted a message to EKEDC on Sunday: Complete blackout for four days running on 21 Road, Festac. Please give us power to at least pump water.”
EKEDC replied that his area was affected by the reduction in grid allocation and that engineers were working to restore full supply.
Flooding Hits Osun Injection Substation, Cutting Power to 14 Communities
In Osun State, the Ibadan Electricity Distribution Company reported that a heavy windstorm triggered flooding at the Ilerin Injection Substation, taking out three feeders at once: the Isare 11kV, Irogbo 11kV, and Mount Carmel 11kV lines.
The outage cut electricity supply to at least fourteen communities in the state, including Ifewara, Iwara, Bolorunduro, Irogbo, Ayeso, Odo-Oro, Wesley, Express Area, Ilerin, Irojo, Olomilagbala, Iwikun, Isare, and surrounding areas.
IBEDC said its technical team was on the ground working to restore supply. “We sincerely apologize for the inconvenience,” the DisCo said in a statement, without giving a restoration estimate.
The Osun disruption added to a growing national pattern of weather-related damage to electricity distribution infrastructure. Nigeria’s power sector has faced repeated grid instability this year, with flooding increasingly identified as a threat to transmission and distribution equipment that was not designed to withstand extreme weather events.
Grid Instability Pushes Nigerians to Demand Answers
The back-to-back transmission failures have renewed frustration among electricity consumers in both states. Residents have taken to social media and DisCo customer service channels to demand faster response times and better communication about outage durations.
Some communities in Lagos have now gone without stable electricity supply for several days, with no confirmed restoration date from either the DisCos or TCN.
EKEDC has said it remains in contact with the national grid operator and will issue updates as the transmission lines are returned to service. Details on when that would happen were not immediately available.
The electricity situation in Osun remains similarly unresolved, with IBEDC yet to announce when repairs at the Ilerin substation would be completed. Affected residents said they had received no direct communication from the DisCo about expected restoration timelines.
