India’s Battery Energy Storage Systems (BESS) sector witnessed notable developments in July 2025, marked by key policy advancements, project awards, and the release of new tenders. These milestones reflect the country’s growing focus on energy storage as a critical enabler of renewable energy integration and grid stability.
6.11.1. India's surge in energy demand and rapid shift towards renewable energy sources offers opportunities for emerging Energy Storage System (ESS) technologies. Domestic innovation and manufacturing of ESS technologies can stimulate job creation, economic growth, and position India as a global leader in sustainable and low-carbon energy systems.
India’s National Electricity Plan forecasts a steep rise in storage demand—411.4 GWh by 2031-32, with significant contributions from both pumped storage and battery systems. Costs have decreased dramatically, enhancing the sector’s commercial viability.
The VGF-backed scheme is expected to help meet India’s storage requirement by 2028 and attract an investment of ₹33,000 crore. At a press conference, the minister also announced an extension of the waiver of inter-state transmission charges for storage projects until June 30, 2028.
At the heart of this momentum is the strategic push by the Government of India and various state authorities, backed by institutions like SECI, NTPC, and SJVN, to advance energy storage solutions. A landmark initiative includes the approval of Viability Gap Funding for 13,200 MWh of battery energy storage systems by 2030-31.
6.10.1. In order to maintain quality and standards for Battery Energy Storage Systems, the Central Government may consider issuing an "Approved List of Models and Manufacturers (ALMM) for BESS" for power sector applications, similar to the list of ALMM for Solar Photovoltaic Modules issued by the Ministry of New and Renewable Energy (MNRE).
