THDC India Ltd has announced the successful commencement of the commercial operations process of the first unit (250 MW) of the 1,000-MW Variable Speed Pumped Storage Plant (PSP) at Tehri, Uttarakhand.
This landmark achievement marks a historic milestone in India’s renewable energy journey, establishing the Tehri PSP as the largest Pumped Storage Plant by any Central Public Sector Enterprise (CPSE) and the first Variable Speed PSP in the country, a government release said.
The commencement was virtually graced by Manohar Lal, Union Minister of Power, Housing and Urban Affairs, Government of India.
Manohar Lal, while addressing the gathering stated that the successful operation of 1st unit of India’s first Variable Speed Pumped Storage Plant at Tehri is not just a technological achievement by THDCIL, but a bold stride towards India’s energy self-reliance. The project will significantly strengthen our grid stability and support the integration of renewable energy. Variable speed technology allows us to manage power flow with precision, making our energy ecosystem smarter and more flexible.
The Union Minister congratulated the entire THDCIL team, implementing partners, and every individual who contributed directly or indirectly to this historic success.
Largest hydropower complex
R.K. Vishnoi, CMD, THDCIL, conveyed his heartfelt congratulations on this significant achievement and stated that once fully operational, this project will elevate the Tehri Hydro Power Complex’s capacity to 2,400 MW, making it India’s largest hydropower complex. This project will be instrumental in converting off-peak surplus energy into peaking power, enhancing grid resilience and supporting round-the-clock power availability.
Designed to provide flexible peaking power and critical grid balancing support, the Tehri Variable Speed PSP represents a significant leap forward in India’s ability to manage intermittent renewable energy. This commissioning milestone reaffirms THDCIL’s leadership in State-of-the-Art Hydropower solutions and bolsters India’s clean energy credentials on the global stage. The power electronics and controls, along with the 250 MW variable-speed pumped storage hydropower unit, have been supplied by GE Vernova, the release noted.
