India’s energy storage sector reached a turning point in 2025 as tenders and pilot schemes give way to visible grid-scale capacity. Policymakers, developers and utilities are now treating storage as core infrastructure, not an experiment, after a year of sharply increased procurement and the first signs of operational fleets on the ground.
India energy storage market gains momentum
The India Energy Storage Market Report 2025 shows a total of 102 GWh of storage capacity was tendered during the year, a jump of 1.4 times compared with the cumulative tenders seen in 2024. Battery energy storage has led the expansion, rising from 4 GWh in 2023 to 24 GWh and then to 60 GWh in 2025. Falling global battery prices and targeted policy measures have combined to make large-scale storage commercially viable.
Beyond headline tender volumes, the pipeline is evolving in quality as well as quantity. New business models are emerging, including thermal power plants paired with storage and the use of storage as a transmission asset to defer network upgrades. Competition at bid stage has intensified and tariff structures remain under discussion, signalling that developers view storage as a strategic long-term market rather than a niche opportunity.
Operational capacity is now visible on the ground. Eleven projects are reported to be running with a combined installed storage capacity of around 0.8 GWh. These projects include standalone battery systems and hybrid solar-plus-storage installations across multiple states and utilities, allowing grid operators to build real operational experience rather than relying solely on demonstration sites.
State-level policies are reinforcing national schemes. Large states including Tamil Nadu, Telangana, Andhra Pradesh and Uttar Pradesh have linked renewable energy targets directly to storage deployment, offering land support, incentives and clearer regulatory frameworks. The combined effect of central schemes and state targets is creating continuity for developers planning multi-year portfolios and helping to derisk investment decisions.
For utilities, the shift matters. Storage is increasingly being integrated into grid operations to manage variability, provide ancillary services and support peak demand. With tenders now translating into assets, operational practices and market rules are starting to adapt. Developers are negotiating more complex contracts and grid operators are testing new dispatch and control frameworks.
Challenges remain. Tariff design and revenue stacking need refinement to ensure commercially sustainable returns for storage projects. Grid interconnection procedures, land allocation and project permitting must keep pace with the faster deployment timeline. But the early signs are promising: the market is moving from pilots and feasibility work to tangible capacity that can affect supply, flexibility and reliability.
Looking ahead, the next few years will determine how rapidly India can convert growing tender pipelines into dependable multi-gigawatt-hour capacity. If current trends continue — falling battery costs, supportive tender structures and clearer state-level targets — storage is likely to become a central pillar of India’s renewable transition and a vital tool for grid modernisation.
Key Takeaways:
- India energy storage tenders jumped to 102 GWh in 2025, 1.4 times the cumulative 2024 pipeline.
- Battery energy storage rose to 60 GWh in 2025 from 4 GWh in 2023, driven by falling costs and policy support.
- Eleven operational projects now provide about 0.8 GWh, giving utilities real grid experience.
- State targets and new business models are turning tenders into long-term assets.
