New Delhi: NTPC Group is advancing a robust pipeline of pumped storage projects (PSPs) with a total planned capacity of 20 GW across multiple sites in India, according to a senior company official. The company aims to commission 3 to 5 GW of these projects by the fiscal year 2031-32, marking a significant milestone in enhancing the country’s energy storage capabilities.
Tehri Pumped Storage Project Sets the Stage
NTPC’s hydro subsidiary, THDC India, has already made progress by constructing a 1,000 MW pumped storage project at Tehri in Uttarakhand. The facility comprises four units of 250 MW each, with the first unit recently commencing commercial electricity supply earlier this month.
“We expect our first 1,000 MW PSP to be commissioned at Tehri in FY26, followed by an additional 3 to 5 GW by FY32,” the official stated, highlighting NTPC’s strategic roadmap for pumped storage assets.
Pumped Storage Projects: A Long-Term Energy Solution
Pumped storage projects are vital components of India’s renewable energy ecosystem. Offering operational lives exceeding 40 years and regulated returns, PSPs serve as critical infrastructure to support energy stability. They provide long-term sustainability by balancing the intermittency of renewable sources like solar and wind, thus enhancing energy security and contributing to climate change goals.
Progress on Project Feasibility and Development
The official revealed that preliminary feasibility studies have been completed for 18 pumped storage projects. Additionally, detailed project reports for four of these projects are in advanced stages of completion, signaling imminent development activity.
This growing portfolio of energy storage solutions aligns with NTPC’s commitment to integrating more renewable capacity and strengthening India’s power infrastructure resilience.
NTPC’s Expansive Power Capacity
As India’s largest integrated power utility, NTPC Ltd currently supplies about 25% of the country’s electricity demand through a diverse energy mix including thermal, solar, and wind. As of June 13, 2025, NTPC’s standalone commercial capacity stands at 60,266 MW, while the group’s total capacity, including subsidiaries, reaches 81,368 MW.
The company’s ongoing investment in pumped storage reflects its strategic vision to support India’s clean energy transition while ensuring grid reliability.
