Pumped Storage Hydropower

This PIB backgrounder details the role of Pumped Storage Hydropower (PSPs) in supporting India's clean energy transition and integrating renewable energy into the grid. It outlines the mechanics of PSPs, classification into on-stream and off-stream (open-loop and closed-loop) schemes, and current operational and pipeline capacities as of 2026. According to the Central Electricity Authority, India has identified 320 pumped storage projects with a combined potential of 345.38 GW. The source also discusses global capacities based on IRENA data, where India ranks fourth globally, and enumerates various government policy measures, guidelines, and regulatory reforms designed to scale up long-duration energy storage infrastructure.
