India’s stationary energy storage sector is experiencing significant growth, with Battery Energy Storage Systems (BESS) projects totaling 92 GWh in the pipeline, a report revealed. The India Energy Storage Alliance (IESA) report also anticipates that the current cumulative installed capacity of less than 1 GWh could soar to 346 GWh by 2033. Over the past year, the sector has witnessed a surge in activity, with 69 new BESS tenders amounting to 102 GWh, marking a 35% increase from 2024.
Installed stationary storage capacity is projected to reach 346 GWh by 2033, with a potential rise to 544 GWh if policy momentum continues, as per the report. Additionally, pumped hydro energy storage is expected to witness substantial growth, with capacity forecasted to escalate from 7 GW in 2025 to 107 GW by 2033. S.C. Saxena, Chairman and Managing Director of GRID India, emphasized the increasing importance of large-scale energy storage due to rising demand fluctuations in India’s power system.
The declining costs and favorable policies are key drivers behind the swift adoption of battery and pumped hydro storage solutions, according to industry experts. Debmalya Sen, President of IESA, highlighted that the white paper outlines a roadmap to support India’s goal of achieving 500 GW of non-fossil fuel capacity by 2030, with energy storage playing a pivotal role. The sector’s growth has been attributed to policy measures like Energy Storage Obligations, Viability Gap Funding, and regulatory backing, including transmission charge waivers, which have enhanced investment feasibility.
With an estimated commissioning of nearly 5 GWh of new capacity in 2026, the energy storage sector is poised for significant expansion, positioning India as a key player in the global energy storage arena. The report was unveiled at the Stationary Energy Storage India (SESI) 2026 conference.
