India’s drive toward 500 GW of renewable capacity by 2030 has placed energy storage at the center of its clean power agenda.
Yet despite this momentum, cost-effective and scalable storage solutions for commercial and industrial (C&I) users remain scarce. Kalpa Power Private Limited aims to bridge that gap with WATTBANK, the country’s first productized Battery Energy Storage Service (BESS), a model designed to integrate storage directly into C&I operations without the complexity of custom engineering or long payback timelines.
Launched in Pune, the 130 kW pilot installation at Amar Business Zone demonstrates how WATTBANK can reshape on-site energy management for corporate facilities. The system allows the building to operate as a net-zero complex by combining daytime solar generation with evening storage discharge. For typical 1 MW users, Kalpa Power estimates annual savings between ₹80 lakhs and ₹1 crore through reduced peak electricity tariffs — a figure that positions storage as both a sustainability and economic play.
WATTBANK operates on Lithium Iron Phosphate (LiFePO₄) battery chemistry, known for stability, safety, and long cycle life. Its modular design provides flexibility in deployment while ensuring reliability for grid-connected businesses. Kalpa Power’s model extends beyond installation: it bundles energy audits, system design, implementation, real-time data monitoring, and lifecycle management into a single, service-based offering. That productization reduces the need for specialized project-by-project engineering — a major barrier that has slowed BESS adoption across India’s C&I segment.
For India’s power-intensive sectors, evening peak pricing remains one of the biggest operational expenses. WATTBANK’s ability to offset these costs from “day one,” as Kalpa Power claims, could give it an edge in a market still cautious about return on investment in energy storage. The use of LiFePO₄ batteries also addresses safety and longevity concerns that have limited lithium-ion deployment in hot climates.
Rounak Muthiyan, Founder and Director of Kalpa Power, frames the launch as a structural shift rather than a one-off project. “Energy storage is the missing link in India’s renewable ecosystem,” he said, emphasizing that aligning power availability with demand is key to overcoming solar intermittency. His view aligns with government and industry calls for dispatchable renewable capacity — a requirement for integrating variable renewables into industrial-scale consumption.
The timing of Kalpa Power’s rollout coincides with increased policy focus on distributed storage. India’s Ministry of Power has introduced incentives for standalone BESS projects and is developing frameworks for storage-as-a-service models. WATTBANK appears to pre-empt these trends by embedding both hardware and financial structuring into a ready-to-deploy service, sidestepping the capital-intensive procurement that often hinders adoption.
