Kalpa Power Launches WATTBANK, India’s First Productized Battery Energy Storage Service, Helping C&I Enterprises Cut Peak Power Costs By Up To 50%

Kalpa Power Private Limited, one of India’s leading solar energy management companies, has launched WATTBANK — the nation’s first productized Battery Energy Storage Service (BESS). Designed specifically for commercial and industrial (C&I) enterprises, WATTBANK enables businesses to cut their evening peak electricity tariffs by up to 50% from the very first day of operation. By storing excess solar energy generated during the day and supplying it during expensive evening hours, the system helps typical 1 MW facilities achieve annual savings ranging between ₹80 lakhs and ₹1 crore.

The project marks one of the first large-scale commercial installations of its kind in Pune. The 130 kW setup, located at Amar Business Zone, forms part of a broader integrated solar-powered system that allows the entire office complex to operate as a true net-zero facility. Through WATTBANK, Kalpa Power has introduced a fully integrated and productized service model that combines energy audits, tailored storage design, end-to-end implementation, real-time data monitoring, and comprehensive lifecycle management.

Built with a lifespan of 25 years, WATTBANK employs Lithium Iron Phosphate (LiFePO4) batteries, renowned for their superior safety, long cycle life, and high efficiency. Beyond cost savings, the system enhances energy reliability by managing fluctuations in electricity demand, improving grid stability, and reducing issues related to overloading. This makes it a sustainable and economically viable solution for energy-intensive commercial operations.

According to Rounak Muthiyan, Founder and Director of Kalpa Power, energy storage represents the crucial missing link in India’s renewable energy ecosystem. He emphasized that BESS technology ensures power availability aligns with demand, overcoming the intermittent nature of solar energy. “With WATTBANK, we are accelerating the clean energy transition while delivering immediate cost benefits to businesses,” Muthiyan stated.

India’s commitment to achieving 500 GW of renewable energy capacity by 2030 has intensified the need for advanced storage technologies like BESS. As the country moves toward round-the-clock renewable power, integrated energy storage systems will play a pivotal role in ensuring both stability and scalability. Through innovations like WATTBANK, Kalpa Power is setting a new benchmark for the industry—offering clients a clear, practical pathway to achieve energy independence, substantial cost reductions, and meaningful contributions toward the national goal of net-zero emissions.
