Kalpa Power Private Limited, a leading solar energy management company in India, has launched WATTBANK, the country’s first productized Battery Energy Storage Service (BESS) designed for commercial and industrial (C&I) enterprises. This innovative solution enables businesses to reduce their evening peak electricity tariffs by up to 50% from the first day of operation. By storing excess solar energy generated during the day and supplying it during expensive evening hours, WATTBANK helps typical 1 MW facilities achieve annual savings of ₹80 lakhs to ₹1 crore.
The project marks one of the first large-scale commercial installations of its kind in Pune, with a 130 kW setup located at Amar Business Zone. The system is part of a broader integrated solar-powered system that allows the entire office complex to operate as a true net-zero facility. WATTBANK is 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.
The system employs Lithium Iron Phosphate (LiFePO4) batteries, known for their superior safety, long cycle life, and high efficiency. With a lifespan of 25 years, WATTBANK 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 is the crucial missing link in India’s renewable energy ecosystem. WATTBANK ensures power availability aligns with demand, overcoming the intermittent nature of solar energy. With India committed to achieving 500 GW of renewable energy capacity by 2030, advanced storage technologies like BESS will play a pivotal role in ensuring stability and scalability.
Through WATTBANK, Kalpa Power is setting a new benchmark for the industry, offering clients a clear pathway to achieve energy independence, substantial cost reductions, and contributions toward the national goal of net-zero emissions. The company’s innovation is expected to accelerate the clean energy transition in India, delivering immediate cost benefits to businesses while promoting sustainable energy practices. As the country moves toward round-the-clock renewable power, integrated energy storage systems like WATTBANK will be essential in ensuring a reliable and efficient energy supply.
