In Detail : JSW Energy is preparing to commission its 5 GWh battery assembly unit in Pune by the third quarter of FY26. The company aims to strengthen its presence in the growing energy storage segment as India accelerates the adoption of renewable energy. This project marks an important step in JSW’s broader transition towards sustainable and integrated energy solutions.
The Pune facility will assemble advanced lithium-ion batteries designed to support large-scale Battery Energy Storage Systems (BESS). These systems will play a key role in stabilizing the grid, managing intermittent renewable generation, and ensuring reliable power supply. The unit’s operations will align with India’s ambitious renewable energy expansion plans.
JSW Energy plans to utilize the Pune unit to meet domestic content requirements outlined in national energy policies. By localizing assembly and sourcing components domestically where possible, the company aims to strengthen India’s clean energy supply chain. This will also help reduce import dependence for critical battery technologies.
The battery assembly plant will cater to both utility-scale and commercial storage projects. JSW Energy intends to deploy these systems across its renewable power portfolio to optimize generation and enhance flexibility. The company also plans to offer storage solutions to external clients, expanding its footprint in the rapidly growing energy storage market.
Energy storage is becoming a critical component of India’s energy transition strategy. With increasing solar and wind capacity additions, the need for grid balancing and peak power support is greater than ever. JSW Energy’s investment in this facility demonstrates a strategic response to the evolving market dynamics.
The Pune facility is expected to feature state-of-the-art technology, efficient automation, and high safety standards. It will be designed for scalability, enabling expansion in line with future demand. The company has indicated that the project will also generate employment opportunities and boost local manufacturing in Maharashtra.
JSW Energy’s broader vision includes developing a total energy storage capacity of 20 GWh over the coming years. The Pune plant serves as the foundation for this goal, creating a domestic platform for assembling high-quality, reliable batteries for both stationary and mobility applications.
In addition to the Pune project, JSW Energy continues to diversify its renewable portfolio with large solar, wind, and hydro projects. The integration of battery systems into its operations will help the company deliver round-the-clock renewable energy solutions and strengthen its competitiveness in India’s evolving power market.
By establishing this 5 GWh assembly unit, JSW Energy reinforces its commitment to India’s “Make in India” initiative and sustainable energy transition. The company’s focus on localized energy storage solutions highlights its role in supporting grid modernization, renewable integration, and the nation’s long-term decarbonization goals.
