Residents in 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 a force majeure at the Oworonshoki 132/33kV and Lekki 330/132kV transmission substations following persistent rainfall that caused extensive flooding across parts of the state.
In a statement issued by its General Manager of Public Affairs, Ndidi Mbah, the company disclosed that the Oworonshoki 132/33kV Transmission Substation has been completely shut down after floodwaters submerged critical equipment, affecting two power transformers.
According to TCN, the affected transformers—TR1 (60MVA) and TR3 (30MVA)—tripped despite efforts to restore them to service.
“Although the Lekki 330/132kV Transmission Substation remains operational, as water is continuously being pumped out of the station, the Oworonshoki 132/33kV Transmission Substation is currently out of service. The flood has affected two power transformers, TR1 (60MVA) and TR3 (30MVA), which tripped on no load even after restoration attempts,” the statement read.
The company further explained that all protection and control cables connected to the affected transformers are submerged, making restoration efforts difficult as heavy rainfall continues.
TCN assured residents that its engineers are working around the clock to evacuate the floodwater and assess the damaged equipment for possible restoration.
“Our engineers are doing everything possible to evacuate the floodwater to enable them to test the transformers and restore supply as quickly as possible,” the company stated.
TCN expressed regret over the disruption and apologised to customers of Eko Electricity Distribution Company (EKEDC) affected by the outage, assuring them that updates would be provided as restoration efforts progress.
