India’s ambitious renewable energy roadmap received a powerful boost today as Secretary Pankaj Agarwal initiated the commercial operation process for the second 250 MW unit of the Tehri Variable Speed Pumped Storage Plant. Located in Uttarakhand, this 1,000 MW facility—built by THDC India Limited—is the largest PSP executed by a central PSU and the nation’s first to integrate variable‑speed technology for enhanced grid integration saurenergy.com+13himachaltonite.com+13pib.gov.in+13.
The virtual launch brought together senior figures from the Ministry of Power, including Additional Secretary Akash Tripathi and Joint Secretary Mohammad Afzal, and industry leaders such as NTPC CMD Gurdeep Singh and THDCIL CMD R.K. Vishnoi. Secretary Agarwal hailed the milestone as “path‑breaking,” noting its critical role in enabling seamless renewable energy integration and bolstering grid flexibility observenow.com+10thenewsmanofindia.com+10government.economictimes.indiatimes.com+10.
Mr. Vishnoi remarked that when all four units are fully operational, the Tehri Hydro Power Complex will deliver a total generation capacity of 2,400 MW. The reversible units allow energy storage during off‑peak hours and dispatch during peak demand, thereby providing reliable balancing of fluctuating renewable output and reducing fossil fuel reliance thdc.co.in+1government.economictimes.indiatimes.com+1.
The installation of variable‑speed turbines, supplied by GE Vernova, signifies a significant technological advancement, enabling the plant to modulate power flow with unprecedented precision—critical for a modern, flexible energy framework indianmasterminds.com+6saurenergy.com+6infralog.in+6. The first unit, which entered COD on June 7, 2025, was followed by the second on July 4, reinforcing THDCIL’s disciplined execution strategy pib.gov.in+4indianmasterminds.com+4saurenergy.com+4.
Designed to produce approximately 2,442 million units of peaking power annually, the PSP leverages the Tehri Dam’s upstream reservoir and Koteshwar Dam’s downstream setup, enabling dynamic load management across the Northern grid en.wikipedia.org+4thdc.co.in+4observenow.com+4. This project exemplifies how advanced hydropower can buffer weather‑dependent energy sources like solar and wind, addressing one of the most pressing challenges in the global energy transition.
With Units 3 and 4 scheduled for commissioning by September 2025, the Tehri PSP is not just a regional success—its innovative blueprint is expected to guide future hydropower developments across India’s diverse terrains electricalindia.in+13thdc.co.in+13thenewsmanofindia.com+13pib.gov.in+15cspm.gov.in+15thenewsmanofindia.com+15.
