Several parts of Lagos State have been thrown into darkness after severe flooding disrupted operations at key electricity transmission facilities.
The Transmission Company of Nigeria (TCN) on Wednesday declared force majeure on the Oworoshoki 33KV and Lekki 330/132KV Transmission Substations following flooding caused by persistent rainfall across the state.
In a statement issued by its General Manager, Public Affairs, Ndidi Mbah, TCN disclosed that the Oworoshoki 133/33KV Transmission Substation has been completely shut down after floodwaters affected two power transformers.
According to the company, while the Lekki 330/132KV Transmission Substation remains operational as engineers continue pumping out water, the Oworoshoki facility is currently out of service.
“The level of water has affected two power transformers, TR1 – 60MVA and TR3 – 30MVA, which tripped on no load even after attempted restoration,” the statement said.
TCN added that the protection and control cables of the affected transformers remain submerged, making restoration efforts difficult.
“Presently, all power protection and control cables of the two power transformers are submerged in water, and efforts to evacuate the floodwater have proved ineffective as the rain continues to fall,” the company stated.
Despite the setback, TCN assured residents that engineers are working round the clock to drain the flooded substation and restore electricity supply as quickly as possible.
“Our engineers are doing everything possible to evacuate the floodwater to enable them to test the transformers for restoration,” the statement added.
The company also apologised for the disruption, expressing regret over the inconvenience caused to customers of Eko Electricity Distribution Company (EKEDC) served by the affected substations.
