India’s energy storage sector is experiencing unprecedented momentum, with the cumulative stationary energy storage market soaring from 122 GWh to 224 GWh in just one year, a remarkable 1.8x increase. The project pipeline has rapidly expanded, with 60 GWh under execution, 80 GWh in various tendering stages, and 35 GWh already awarded. The total pipeline of BESS projects now stands at 92 GWh, while pumped storage projects (PSP) have surged from 50 GWh to 132 GWh since last year. With India set to commission nearly 5 GWh of new capacity in 2026, an almost tenfold jump in installed capacity, the sector is poised for a breakthrough year.
Adding to this momentum, 69 new BESS tenders totaling 102 GWh were issued in the past year alone, marking a 35% jump over 2024 and nearly doubling the annual tender volume. Landmarks such as Adani’s strategic entry with the world’s largest single-location BESS project, NTPC’s innovative long-duration storage demonstration, and the upcoming launch of India’s largest Solar+BESS tender in Rajasthan signal a rapidly maturing market. The stage is set for merchant BESS, thermal+BESS, and new C&I applications to take off in 2026.
Against this backdrop, the India Energy Storage Alliance (IESA) is set to unveil its landmark White Paper on the Stationary Energy Storage Market at the Stationary Energy Storage India (SESI) 2026 conference. SESI 2026 will be held on March 20, 2026 at Yashobhoomi, Dwarka, New Delhi, on the sidelines of the Bharat Electricity Summit. The event is expected to bring together more than 300 industry leaders, government officials, and international partners from over 10 countries.
The new White Paper, developed in partnership with Customized Energy Solutions (CES), delivers the most comprehensive analysis to date of India’s burgeoning stationary storage sector. It tracks the rapid surge in market activity and highlights how India is on track to achieve its ambitious targets: 500 GW of non-fossil generation by 2030 and over 236 GWh of battery storage by 2032, all while integrating renewable energy, boosting grid reliability, and opening new investment frontiers.
“India’s energy storage market is not just growing, it is evolving at an unprecedented pace and scale. This White Paper provides a much-needed roadmap for policymakers, investors, and industry leaders to align their strategies and fast-track deployment. At IESA, we believe that through collective effort and innovation, India can lead the world in sustainable energy solutions,” said Debmalya Sen, President, India Energy Storage Alliance.
Vinayak Walimbe, Managing Director, Customized Energy Solutions, said, “As India stands at the threshold of a transformative energy era, the launch of our FTM Stationary Energy Storage Market White Paper at SESI 2026 is a clarion call for industry, government, and innovators to collaborate for a greener, more resilient grid. The insights and vision shared in this report will empower stakeholders to turn challenges into opportunities and help India realise its climate and energy goals.”
SESI 2026 will feature high-profile keynote addresses, including Shri Shripad Yesso Naik, Minister of State for Power and New & Renewable Energy; top executives from the Ministry of Power, MNRE, SECI, CEA, and GRID India; and global partners such as the World Bank.
The White Paper details critical policy and regulatory milestones, including the rollout of Energy Storage Obligations (ESO), Viability Gap Funding (VGF), and the formal recognition of storage in the Electricity Amendment Rules 2025. It forecasts up to 544 GWh of cumulative BESS and 143 GW of pumped hydro installations by 2033, and explores new market segments like merchant BESS, storage-backed green hydrogen, and C&I decarbonization.
Attendees will participate in expert-led talks, exclusive project showcases, including India’s largest BESS projects, innovative long-duration storage pilots, and record-setting tenders, plus deep-dive panel discussions on policy, technology, and financing. The event’s agenda will enable delegates to gain invaluable insights into government policies, the latest projects, and the evolving business and regulatory landscape shaping India’s energy storage journey.
By bringing together policymakers, utilities, developers, technology providers, and investors, SESI 2026 serves as the national forum to drive implementation, foster partnerships, and accelerate the deployment of storage across the value chain. The White Paper launch will set the tone for forward-looking dialogue and help align stakeholders around actionable solutions for India’s clean energy transition.
