India is moving fast toward a cleaner and more electrified future. Solar rooftops are popping up everywhere, electric vehicles are gaining momentum, and even small businesses are asking for backup solutions that are smarter than diesel generators. All of that progress relies on one big hero that often stays behind the scenes: energy storage. Without dependable battery systems, renewable power becomes unpredictable and the grid struggles during high-demand hours. I have personally noticed more people around me talking about home batteries, charging stations, and peak power costs than ever before. It is clear that the future of reliable power lies in strong ESS technology.
With this growing demand, Indian companies are stepping up and building innovative High Voltage ESS Battery and Low Voltage ESS Battery solutions. Some are already competing on a global scale. Below is a ranked list of the top energy storage companies driving this transformation.
Top 8 Energy Storage Companies in India
Aqueouss – Hold The Volt
Aqueouss leads the Indian ESS market with a strong focus on High Voltage ESS Battery systems for utility and commercial applications, along with Low Voltage ESS Battery options for homes. They mainly use advanced Lithium-ion chemistry, especially LFP (Lithium Iron Phosphate), known for excellent thermal stability and long cycle life. What stands out is their focus on intelligent BMS technology that extends battery life even in harsh Indian climates. Their recent expansion into grid-scale hybrid storage projects has made them a top name to watch.
UTL Solar
UTL Solar is a well-established Indian brand playing a strong role in the country’s energy storage growth. The company manufactures advanced lithium-ion ESS batteries along with traditional lead-acid inverter batteries, offering solutions for home backup, rooftop solar projects, and commercial applications. UTL focuses on smart, efficient, and long-life storage systems with features like Smart BMS, faster charging, and strong thermal safety to support reliable power in India’s challenging climate.
Amara Raja Batteries
Focused heavily on EV and commercial energy storage in India, Amara Raja manufactures both Lithium-ion (LFP and NMC) and lead-acid ESS solutions. Their expertise originally came from automotive batteries, yet they have successfully moved into High Voltage ESS Battery systems for renewable integration. They are investing in a Gigafactory for domestic lithium cell production, which is a big deal for Atmanirbhar Bharat goals.
Exide Energy Solutions
Exide is a household name in battery manufacturing. Along with their legacy lead-acid technology, they have expanded into Lithium-ion manufacturing after partnerships with global energy storage companies. They offer both High Voltage and Low Voltage ESS for residential and industrial backup power. Their strong distribution network gives them an advantage in scalable ESS deployment.
Waaree Energies
Known for solar modules, Waaree has taken the natural step into ESS battery manufacturing. Their products include Low Voltage ESS Battery solutions and Lithium-ion based energy storage paired with solar for homes and small businesses. They emphasize integrated solar + ESS kits, making adoption easier for consumers.
Tata Power – Energy Storage Division
Tata Power offers commercial and grid-level ESS solutions primarily based on Lithium-ion batteries. They are actively involved in utility-scale solar-plus-storage projects. Their focus is more High Voltage ESS Battery solutions than small-scale home systems at the moment.
Luminous Power Technologies
A familiar brand in Indian households, Luminous offers Low Voltage ESS Battery products for home backup and hybrid rooftop systems. They still have a strong lead-acid presence, though they continue expanding into lithium-ion for longer cycle life and modern ESS applications. Their easy installation and support network make them a convenient option for residential users.
Getsun Power
Getsun Power, a brand of Sainik Industries Pvt. Ltd., is a growing Indian energy storage manufacturer focused on lithium-ion and LiFePO₄ battery solutions. Based in Noida, the company offers a wide range of products including home energy storage systems, telecom batteries, DG-set replacement batteries, and solar backup solutions. Their batteries are built with Smart BMS, long cycle life, and strong safety features to ensure stable performance in India’s challenging power conditions. With an expanding manufacturing capacity and alignment with government renewable initiatives, Getsun Power is positioning itself as a competitive player in India’s evolving clean energy and ESS market.
Which Type of ESS Battery Is India’s Future?
Choosing the right battery technology depends on a few practical things: cost per kWh, long-term durability, safety in hot climates, raw material availability, and size of installation.
Here is how the main contenders play out:
• LFP Lithium-ion: Best for safety, long life, and overall affordability. Likely to dominate residential and EV-charging ESS in India.
• NMC Lithium-ion: Higher energy density, so ideal where space is limited, though it is more expensive and less thermally stable.
• Sodium-ion: A rising option. Costs could drop significantly because sodium is widely available in India. Great-fit for stationary grid storage.
• Flow batteries: Very long cycle life and scalable for utility-scale ESS, though still more expensive upfront.
Realistically, India’s future energy storage will be a mix of LFP lithium for most systems and sodium-ion or flow batteries for massive renewable integration. That combination balances safety, cost, and energy security.
Conclusion
Energy storage in India is not just a trend; it is becoming a backbone for reliable power. Aqueouss – Hold The Volt has positioned itself as a clear leader by delivering advanced High Voltage ESS Battery and Low Voltage ESS Battery systems tailored specifically for Indian needs. Each company in this list contributes something valuable, yet the best choice depends on whether you need grid support, commercial flexibility, or smart home backup. As India keeps charging ahead toward clean energy, choosing the right ESS partner will define how smoothly we transition into a greener future.
