With an aim to improve its power generation efficiency, Gujarat government has decided to completely overhaul its power generation technology in state-owned power stations in the state. And as part of the plan, Gujarat State Electricity Corporation Limited (GSECL) is going to change the turbines of two of its thermal power units in Ukai of South Gujarat and Wanakbori of Central Gujarat at the cost of around Rs 208 crore.
Sources in the government said that the current turbine technology of Ukai and Wanakbori power stations was more than 25 years old and it had outlived its lifespan. And therefore, the Energy and Petrochemicals Department had initiated the move to overhaul the turbines in the thermal power stations.
The sources said that the Ukai Thermal Power Station has total six power generation units – two units of 120 MW, three units of 200 MW and one unit of 500 MW power generation capacity. The power station has total power generation capacity of 1,340 MW. Sources added that one of the three units of 200 MW capacity would be changed in the initial stage of the project to overhaul the power generation technology by retrofitting of new turbines.
The Wanakbori Thermal Power Station, on the other hand, has total power generation capacity of 1,470 MW with total six units of power generation capacity of 210 MW each. One of the seven units will witness total overhaul of turbine technology along with the one unit of Ukai Thermal Power Station.
The sources added that the total cost of overhauling the two power generation units was estimated at around Rs 208 crore and the contract for the same has already been awarded. Overhauling of the two power generation units will start in December this year and is likely to be completed within eight to ten months. During this period, the unit will witness shut down of around 100 days.
Apart from Ukai in Tapi district and Wanakbori and Dhuvaran in Anand district, GSECL has thermal power stations in Gandhinagar and Sikka of Jamnagar. Sources said that the technology upgradation would be done in all these stations in a phased manner.
