Energy Storage
Pumped Hydro and Battery Storage Systems
Grid-scale energy storage is essential to integrate variable renewable energy (solar, wind) reliably. Pumped Storage Projects (PSP) use surplus off-peak electricity to pump water to an elevated reservoir, releasing it through turbines during peak demand — a mature, long-duration storage technology. Battery Energy Storage Systems (BESS), typically lithium-ion based, provide faster-response, shorter-duration storage and are being scaled up under government schemes such as viability gap funding (VGF) for BESS announced by the Ministry of Power.
- Pumped storage capacity under construction: about 15,870 MW / 95,220 MWh.
- BESS capacity under construction: about 15,754 MW / 42,530 MWh.
- The Ministry of Power has approved viability gap funding schemes to make standalone BESS projects commercially viable, given high upfront capital costs.
