India’s cumulative installed battery energy storage system (BESS) capacity is projected to reach 346 GWh by 2033 from less than 1 GWh today, according to a white paper by the Indian Energy Storage Alliance (IESA) and Customized Energy Solutions (CES).
India's stationary energy storage market is expanding rapidly, with 69 new BESS tenders totaling 102 GWh launched over the past year – a 35% increase over 2024 and nearly double the annual tender volume – according to a white paper released at the recent Stationary Energy Storage India (SESI) 2026 conference.
Cumulative installed capacity currently stands at less than 1 GWh, with 92 GWh of projects now in the pipeline.
The report, prepared by IESA in partnership with CES, projects installed stationary storage capacity will reach 346 GWh by 2033 under a base scenario, rising to 544 GWh if policy momentum continues.
Pumped hydro energy storage (PHES) capacity is projected to grow from 7 GW in 2025 to 107 GW by 2033.
