Replus Engitech, a subsidiary of Bhilwara Energy, has launched India’s first 5 MWh, 20-foot containerised Battery Energy Storage System (BESS) — marking a major leap for the country’s renewable energy infrastructure. The innovation combines liquid cooling, intelligent monitoring, and multi-level fire protection, strengthening India’s grid-scale storage capabilities.
Developed entirely in-house by Replus, the system is engineered for India’s diverse climatic conditions. “This is a made-in-India product, designed for local conditions,” said Hiren Pravin Shah, Managing Director and CEO of Replus Engitech.
Engineered for Indian Conditions
Built to endure temperatures exceeding 50°C, the system maintains internal conditions at 25°C ± 2°C, ensuring optimal battery life of up to 15 years. Each 20-foot container houses eight modular racks, featuring locally developed battery management systems, sensors, and control electronics, with only the cells being imported.
The dual fire protection mechanism, combining oxygen suppression and sprinkler systems, provides rapid response to potential hazards. Real-time monitoring through HMI panels and remote access ensures enhanced operational reliability.
Massive Scale-Up and Future Plans
Replus currently operates a 1 GWh manufacturing facility in Pune, now being scaled up to 5 GWh, with a total investment plan of ₹450–500 crore. The company is executing 1 GWh ESS projects and 200 MWh EV battery projects, with an additional 2.5 GWh pipeline for next year.
In the next phase, Replus plans to diversify into Energy Management Systems (EMS) and integrated power electronics solutions, with ₹50–100 crore earmarked for development. The company is also evaluating cell manufacturing as a strategic step toward self-reliance.
