New Delhi, March 20: India’s stationary energy storage sector is witnessing accelerated growth, with the pipeline of Battery Energy Storage Systems (BESS) projects reaching a record 92 GWh, according to a report by the India Energy Storage Alliance (IESA).
The report projects that installed storage capacity, currently below 1 GWh, could expand sharply to 346 GWh by 2033 under the base scenario, with potential to reach 544 GWh if policy momentum remains strong.
The sector has seen a surge in activity, with 69 new BESS tenders aggregating 102 GWh issued over the past year, marking a 35 per cent increase compared to 2024.
Alongside battery storage, pumped hydro energy storage is also expected to scale significantly, with capacity projected to rise from 7 GW in 2025 to 107 GW by 2033, highlighting a diversified storage strategy.
S. C. Saxena, Chairman and Managing Director of GRID India, said large-scale energy storage is becoming critical to manage demand variability in the power system, with falling costs and supportive policies accelerating adoption.
Debmalya Sen, President of IESA, noted that the roadmap aligns with India’s target of achieving 500 GW of non-fossil fuel capacity by 2030, positioning storage as a key enabler of renewable integration.
The report attributes growth to policy measures such as energy storage obligations, viability gap funding, and regulatory support including transmission charge waivers, which have improved project viability and investor interest.
With nearly 5 GWh of new capacity expected to be commissioned in 2026, India’s energy storage sector is entering a high-growth phase, strengthening its position in the global clean energy ecosystem.
The findings were presented at the Stationary Energy Storage India 2026 conference.
