India’s stationary energy storage sector is witnessing strong growth, with the cumulative market expanding from 122 GWh to 224 GWh within a year, representing a 1.8-fold increase. The surge reflects rising project activity across the country, with approximately 60 GWh currently under execution, 80 GWh in different stages of tendering, and around 35 GWh already awarded.
Industry estimates indicate that the pipeline of battery energy storage system (BESS) projects in India has reached about 92 GWh. Meanwhile, pumped storage projects have also grown significantly, increasing from 50 GWh to 132 GWh over the past year. The sector is expected to witness a major milestone in 2026, with nearly 5 GWh of new energy storage capacity projected to be commissioned.
Tender activity has also accelerated considerably. Over the past year, 69 new BESS tenders totaling 102 GWh were issued across the country, marking a 35% increase compared to 2024 and nearly doubling the annual tender volume. Major developments such as the entry of Adani Group into the energy storage sector with one of the world’s largest single-location BESS projects and long-duration storage initiatives led by NTPC Limited indicate the growing maturity of India’s energy storage ecosystem.
Against this backdrop, the India Energy Storage Alliance (IESA) is preparing to release a comprehensive White Paper on the stationary energy storage market during the Stationary Energy Storage India 2026 (SESI 2026) conference. The event will be held on March 20, 2026, at the Yashobhoomi Convention Centre in Dwarka, New Delhi, alongside the Bharat Electricity Summit.
The White Paper, developed in collaboration with Customized Energy Solutions, offers an in-depth analysis of India’s rapidly evolving energy storage sector. It examines current market trends and outlines pathways for achieving India’s long-term clean energy targets, including 500 GW of non-fossil fuel power generation by 2030 and more than 236 GWh of battery storage capacity by 2032.
Debmalya Sen, President of the India Energy Storage Alliance, said the country’s energy storage market is expanding at an unprecedented pace and scale. He noted that the White Paper is expected to provide a strategic roadmap for policymakers, investors, and industry stakeholders to accelerate storage deployment and support India’s clean energy transition.
Vinayak Walimbe, Managing Director of Customized Energy Solutions, added that the report aims to encourage stronger collaboration between industry players, government bodies, and innovators to build a more resilient and sustainable electricity grid.
SESI 2026 is expected to bring together more than 300 participants, including policymakers, utilities, developers, technology providers, and investors from over 10 countries. The conference will feature keynote addresses from senior government officials, including Shripad Yesso Naik, Minister of State for Power and New and Renewable Energy, along with representatives from the Ministry of Power India, Ministry of New and Renewable Energy India, Solar Energy Corporation of India, Central Electricity Authority, and Grid Controller of India Limited.
The upcoming White Paper also highlights key policy developments shaping the sector, including the rollout of Energy Storage Obligations (ESO), Viability Gap Funding (VGF), and the recognition of energy storage under the Electricity Amendment Rules 2025. According to the report, India could achieve up to 544 GWh of cumulative BESS capacity and 143 GW of pumped hydro installations by 2033, while new segments such as merchant BESS, storage-backed green hydrogen, and commercial and industrial decarbonization are expected to emerge.
Industry experts believe SESI 2026 will serve as a critical platform for advancing partnerships, discussing regulatory frameworks, and accelerating the deployment of energy storage technologies across India’s evolving power sector.
