India: NTPC says it plans to install flue-gas desulphurisation (FGD) units at all of its power stations. The state-owned power producer commissioned the country's first FGD unit at the 500MW unit number 13 (stage V) unit at its 4760MW Vindhyachal power plant in 2017 for a cost of around US$30m, according to the Press Trust of India. 1275t and 1515t of synthetic gypsum from the unit has been supplied to ACC and JP Cement respectively since the unit was started.

"With an aim to embrace sustainable practices to produce power with minimum emissions, NTPC is implementing this technology across its power plants. At present, the adoption of this technology is currently at various stages of implementation for 65.35GW of group capacity in 38 locations, which also includes upcoming projects," the state-owned power producer said.

Earlier in July 2019 GE Power India said it had has won three FGD projects from NTPC at the Simhadri Super Thermal Power Station, the Sipat Super Thermal Power Station and the Aravali Power Company plant, IGSTPP Jhajjar.
