A looming power outage is threatening parts of Nigeria’s commercial capital after flooding from persistent rainfall crippled a key electricity transmission facility, forcing the Transmission Company of Nigeria (TCN) to declare force majeure on two strategic substations.

The utility said the Oworonshoki 132/33kV Transmission Substation has been knocked out of service after floodwaters submerged critical equipment, raising the prospect of prolonged electricity disruptions for customers supplied through the facility.

TCN, in a statement issued on Tuesday, said the force majeure affects both the Oworonshoki 132/33kV and Lekki 330/132kV transmission substations following severe flooding caused by continuous rainfall in Lagos.

While the Lekki 330/132kV Transmission Substation remains operational, the company said emergency crews are continuously pumping out floodwater to keep the facility running.

However, the Oworonshoki substation has been forced offline after rising water levels affected two of its power transformers.
