As the world is shifting to clean energy at a rapid pace, the ability to store that energy efficiently becomes as important as generating it. Whether it is wind, solar, or hydro, renewable energy sources need a dependable storage solution to manage intermittency and ensure a reliable, continuous electricity supply. India is strengthening its renewable energy infrastructure to meet its sustainability goals.
The Government of India has set a target of achieving 500 GW of installed electricity generation capacity from non-fossil fuel-based sources by 2030, with solar and wind expected to contribute a major share. To support this large-scale renewable integration, the National Electricity Plan (2023), published by the Central Electricity Authority (CEA), projects a requirement for 208 GWh of Battery Energy Storage Systems (BESS) by 2030. Energy storage companies in India play an important role in shaping India’s clean energy future by improving grid reliability, energy efficiency, and long-term sustainability.

FAQs
Which is the largest BESS project in India?
As of 2026, the largest BESS project under development in India is Avaada Group’s 2,500 MWh battery storage facility paired with 1,560 MWp of solar at Pugal in Bikaner, Rajasthan. The foundation stone was laid by Prime Minister Narendra Modi in September 2025 and the project is recognised as India’s single largest storage deployment.
What is the difference between BESS and pumped hydro storage?
Battery Energy Storage Systems (BESS) use lithium-ion or similar chemistries to store electricity for short durations typically two to four hours making them ideal for peak shaving and intra-day balancing. Pumped hydro storage uses elevated water reservoirs to deliver six to twelve hours or more of dispatchable power, making it better suited to long-duration and seasonal balancing. Companies like Avaada and JSW are deploying both, while Greenko specialises in pumped hydro.
What is an FDRE project?
Firm and Dispatchable Renewable Energy (FDRE) projects combine solar, wind, and storage at one bid point so the developer delivers contracted power on demand, not just when the sun shines or the wind blows. FDRE tenders typically guarantee availability for specific hours and command higher tariffs than vanilla solar. They have become India’s preferred procurement model for round-the-clock clean power.
How much storage will India need by 2030?
Central Electricity Authority estimates suggest India will need roughly 74 GW / 411 GWh of energy storage by 2032 to support its 500 GW non-fossil capacity target. That makes the 2025-2027 window when most current projects come online critical to the country’s clean energy transition.
