Heavy rainfall across Lagos and Osun states has triggered widespread urban flooding alongside major power outages due to critical transmission line faults. The Eko Electricity Distribution Company (EKEDC) and the Ibadan Electricity Distribution Company (IBEDC) have announced fresh power cuts affecting thousands of residents.
Transmission Line Faults Cause Grid Disruption
EKEDC attributed the blackout to faults on the Oshogbo-Ikeja 330kV and Benin-Egbin 330kV transmission lines, which led to a reduction in grid allocation. In a statement, the company said: "Osogbo/Ikeja 330kV line down. The Benin/Egbin 330kV line is down. Impact: Reduction in grid allocation." As a result, some business units may experience load shedding until normal supply is restored.
Affected Areas in Lagos
The outage has affected several communities across Lagos, including Chevy View Estate, Chevron Drive, Agungi, Alpha Beach, Ikate, Elegushi, Carlton Gate, Kusenla, Victory Park Estate, Oniru, Maroko, Muri Okunola, Ajose Adeogun, Ligali Ayorinde, and parts of Aboyade Cole. Other affected locations include Morinho Drive, Landmark Road, Igbo Efon, Lekki Tollgate 2, Igbokusu, Gbangbala, Platinum Way, Jakande/Coastal Road, OADC/Mayegun, Ajiran, Chevron Alternative Area, and Osapa London.
Flooding Disrupts Osun Communities
IBEDC confirmed that heavy flooding at the Ilerin Injection Substation in Osun State disrupted electricity supply. Floodwater affected the Isare 11kV, Irogbo 11kV, and Mount Carmel 11kV feeders, cutting off power to communities including Ifewara, Iwara, Bolorunduro, Irogbo, Ayeso, Odo-Oro, Wesley, Express Area, Ilerin, Irojo, Olomilagbala, Iwikun, Isare, and neighbouring areas.
Restoration Efforts Underway
Both electricity companies say restoration work is ongoing, but no timeline has been given. EKEDC stated: "We are in constant contact with the national grid operator and will restore supply as soon as the lines are back. Thank you for your patience." IBEDC assured customers: "Our technical team is working to ensure power supply is restored. We sincerely apologise for the inconvenience."
Flood Risk Warnings
The Nigerian Meteorological Agency (NiMet) and the Nigeria Hydrological Services Agency (NIHSA) had earlier warned that Lagos, Osun, and several other states were at risk of flooding during the peak of the 2026 rainy season. Heavy rain has flooded roads, entered homes, slowed traffic, and damaged public infrastructure. Residents are advised to avoid flooded areas and report fallen power lines or damaged electrical equipment to authorities.
