THDC India Limited has successfully synchronised the first 250 MW unit of its 1,000 MW pumped storage project (PSP) at Tehri in Uttarakhand in pump condenser mode.
In pump condenser mode, the turbine operates both to generate electricity and function as a condenser or heat exchanger, enhancing operational flexibility. The Tehri PSP comprises four units of 250 MW each and, once completed, will raise the total installed capacity of the Tehri Hydro Power Complex to 2,400 MW. THDC India currently operates the 1,000 MW Tehri HPP and the 400 MW Koteshwar HEP at the complex.
