An extensive survey of Pumped Hydro Energy Storage (PHES) projects across India was conducted drawing from diverse sources such as CEA reports, academic journals, news articles, magazines, and press releases. Currently, India has 5.6 GW of operational PHES capacity, encompassing both on-river and off-river systems, with an additional 38.7 GW under construction. Furthermore, 43.1 GW of capacity is in advanced planning stages, while 47.5 GW has been announced. Of the planned projects, 65 GW will utilize open-loop systems, and 70 GW will employ closed-loop systems, reflecting a broad technological mix tailored to meet the nation’s energy storage demands. If all these projects are met, India’s total PHES capacity will surge from the current 5.6 GW to an impressive 135 GW, as summarized below. This growth underscores India’s dedication to advancing its renewable energy infrastructure. A detailed state-wise analysis of peak demand, solar and wind installed capacity, and PHES illuminated the need for grid infrastructure development. This work, carried out at NCPRE by interns Srushti Jagtap and Saurav Acharya working under Profs. Anil Kottantharayil and Juzer Vasi, was presented at the 35th PVSEC at Numazu, Japan during 10-15 November 2024.
