India’s rapid expansion of renewable energy is creating a growing need for reliable Battery Energy Storage Systems (BESS). BESS enables electricity generated from solar and other renewable sources to be stored and used when required, helping businesses, utilities and industries manage peak demand, improve grid stability and maintain backup power.
With India’s energy-storage market expanding rapidly, several companies are investing in battery manufacturing, energy storage solutions and large-scale BESS projects. Here are five companies to watch when looking for the top BESS manufacturers in India in 2027.
1. IB Solar
IB Solar, a division of Integrated Batteries, is an Indian clean-energy company offering solar modules and advanced energy-storage solutions. Its energy-storage portfolio includes lithium-based solutions for residential, commercial, industrial and utility applications, with solutions ranging from 1 kW to 10 MW.
IB Solar is also expanding its domestic manufacturing capabilities, including an integrated 3 GWh BESS assembly facility planned in the YEIDA region near Noida. The facility is targeted to commence commercial operations by December 2027, strengthening the company’s focus on domestic energy-storage manufacturing.
Its BESS solutions can support applications such as solar energy storage, backup power, peak-load management and renewable-energy integration.
Best suited for: Residential, commercial, industrial and solar-plus-storage applications.
2. Amara Raja Energy & Mobility
Amara Raja is another major Indian energy-storage company with capabilities spanning conventional batteries, lithium-ion technology and energy storage solutions.
The company has already deployed more than 1 GWh of lithium energy-storage solutions across approximately 50,000 telecom sites, demonstrating significant experience in large-scale distributed storage.
Best suited for: Industrial, telecom, commercial and distributed energy storage.
3. Tata Power
Tata Power is a major player in India’s renewable-energy ecosystem and has been expanding its capabilities across solar, power infrastructure and energy storage.
Its integrated approach allows BESS to be combined with renewable-energy generation, making energy storage particularly relevant for commercial, industrial and utility-scale projects.
Best suited for: Solar-plus-storage, commercial projects and utility applications.
4. Reliance New Energy
Reliance New Energy is investing heavily in India’s advanced battery ecosystem, including technologies designed for large-scale energy storage. The company is developing an integrated clean-energy manufacturing ecosystem covering batteries and other renewable technologies.
Reliance has also demonstrated interest in long-duration energy storage, including non-lithium technologies, which could become increasingly important as India’s renewable-energy capacity grows.
Best suited for: Large-scale energy storage and future utility applications.
5. Exide Energy Solutions
Exide is one of India’s most established names in energy storage. The company is expanding beyond its traditional battery business into lithium-ion cell manufacturing and advanced energy storage solutions.
Its experience across automotive, industrial and backup applications provides a strong foundation for its growing presence in India’s BESS ecosystem.
Best suited for: Industrial energy storage, backup power and large-scale applications.
