Almost 10 days after flood stalled the powerhouse at Ranjit Sagar Dam (RSD), the first unit of 150 megawatts was back into operation on Saturday, easing the electricity-production scene in the state.
The RSD has four units of 150-MW each. "Unit 4 got back into operation at 4.55pm and has been synchronised with the Northern Grid," confirmed GS Chabbra, director (generation) of Punjab State Power Corporation Limited (PSPCL). Still three units are out of operation.
Heavy rain on the night of August 1 caused the flood that shut the 600-MW hydroelectricity plant. As silt and mud got into the turbines, the entire Mobil oil of these machines was required to be changed. The curfew in Jammu stalled its shipment so now the oil is to be brought from New Delhi. A turbine needs 18,000 litres of oil, roughly. PSPCL has paid Rs 98 lakh for it and the cost of repair is Rs 2 crore.
PSPCL officials say that the turbine of the second unit is on rotation to dry out and if all goes as planned, it will be back in operation by Wednesday and the entire project would be up and running by the end of next week. Post heavy rain, PSPCL is confident of meeting the power demand, and after the restoration of one unit, the pressure on it has eased. For the time being, the power restrictions on the industrial sector are off.
