If you’re in parts of Lekki, Ajah, Gbagada or Bariga and your lights are out, this might be why — Lagos rain has forced the Transmission Company of Nigeria to shut down key substations.
So, here’s what’s going on, according to cbinews.tv. The Transmission Company of Nigeria, TCN, has declared *force majeure* on two major substations in Lagos after all this relentless rainfall caused serious flooding.
The two affected sites are the Oworonshoki 132/33kV and Lekki 330/132kV Transmission Substations. TCN’s General Manager for Public Affairs, Mrs Ndidi Mbah, confirmed it on Wednesday, 1 July 2026, in a statement posted to the agency’s official X account.
Right now, Oworonshoki substation is completely out of service. Floodwater got into two power transformers — a 60MVA and a 30MVA — and they tripped even when engineers tried to bring them back online. Mbah said all the power protection and control cables are still submerged, and with the rain not letting up, they haven’t been able to pump the water out yet.
Lekki substation is in slightly better shape. It’s still running, but engineers are working round the clock pumping water out of the facility to keep it that way.
TCN has apologised to Eko Electricity Distribution Plc customers who’ll be affected. And if you’re wondering, *force majeure* basically means TCN is invoking a legal clause that covers them when uncontrollable events — like this flooding — stop them from meeting their obligations. So, they’re protected from legal claims over the outages.
What this means for you::
Expect power disruptions if you’re in Lekki, Ajah, Ibeju-Lekki, Ogudu, Gbagada, Alapere or Bariga. TCN says restoration depends on getting all that floodwater out and checking the transformers for damage. No timeline yet.
What you should know:
This isn’t the first hit to the grid this year. Back in March 2026, TCN carried out maintenance in Niger State and between Gombe and Borno, which also caused outages. They were installing fire and explosion prevention tech on a 150MVA transformer at Fakun substation.
This latest flooding just piles more pressure on Nigeria’s transmission network, while TCN scrambles to keep critical infrastructure running.
