The projects, located at Jeerat and Kharagpur, were secured through e-reverse auctions conducted under a Tariff-Based Competitive Bidding (TBCB). The projects will be executed and operated through JEM, subsidiary of JWL, further strengthening its presence in India's battery energy storage segment. This involves supply and commissioning of an approximately INR 400 crore of BESS project and will operate under a 15-year BOO model with WBSEDCL. The long-term operating model provides JEM with enhanced revenue visibility while strengthening its presence in India's rapidly expanding energy storage market. The latest wins add significant scale to Jupiter Electric Mobility's existing BESS business, which increases its order book to approx. 500 MWh, valued at over INR 500 crore. JEM Energy is building a sizeable portfolio across India's emerging BESS market, targeting a BESS order book of approximately INR 1,000 crore by FY27; reflecting its confidence in the structural growth opportunity for energy storage in India. Speaking on the development, Mr. Vivek Lohia, Managing Director, Jupiter Wagons Limited, said: " The successful bids for 100 MW/400 MWh of standalone BESS capacity in West Bengal mark an important milestone for Jupiter Wagons and JEM Energy as we build a scalable energy storage business. These projects add meaningful scale to our BESS order book, which now stands at approx. 500 MWh, valued at over INR 500 crore, and reinforces our confidence in the long-term opportunity for energy storage in India. Our ambition of building a INR 1,000 crore BESS order book mirrors the pace at which this business is developing and the opportunities we see across utility-scale and commercial applications. As India moves towards a renewable-led power system, we remain committed to developing reliable, technology-driven and scalable energy storage solutions that can support the country's evolving power infrastructure.” The development strengthens JWL's presence in the energy transition ecosystem and supports the Company's strategy of expanding into high-growth businesses beyond its traditional railway and mobility operations. For JEM, the projects add significant scale to its BESS business and create a stronger platform for pursuing further utility-scale and Commercial & Industrial (C&I) opportunities across India.
