India added over 341 MWh of battery energy storage capacity in 2024, a more than sixfold increase from 51 MWh added in 2023, according to Mercom India Research’s newly released India’s Energy Storage Landscape 2024 Report.

India’s cumulative battery energy storage capacity reached nearly 442 MWh as of December 2024.

India has also added 4.7 GW of pumped storage to date.

The strong policy support, including viability gap funding and energy storage obligations, is helping accelerate the adoption of energy storage across the country.

As of December 2024, Karnataka (36%), Chhattisgarh (27%), and Gujarat (17%) held the top three positions in the cumulative installed energy storage capacity.

Solar-plus-storage systems accounted for nearly 60% of India’s cumulative installed capacity. This was followed by approximately 36% from renewable energy projects with round-the-clock capability and about 4% from standalone battery energy storage systems. The remaining share came from floating solar with storage projects.

As of December 2024, India had nearly 4 GWh of standalone battery storage, over 4 GW of solar-plus-storage, and more than 16 GW of renewable energy-plus-storage projects in various stages of development. In addition, over 51 GW of pumped storage was in the pipeline, of which more than 37 GW was in the survey and investigation phase, and over 14 GW was under active development.

Gujarat had the largest pipeline of standalone battery storage capacity under development, followed by Maharashtra and Rajasthan. Favorable provisions in renewable energy policies of these states, along with annual energy storage obligations in place through FY30, were key drivers of growing demand for energy storage.

Various government agencies issued energy storage tenders totaling nearly 27 GW in 2024 and auctioned approximately 17 GW of projects, with or without associated renewable energy capacity. Solar-plus-storage tenders saw significant momentum, recording a 118% year-over-year increase during the year.
