ACME Solar Holdings Ltd has commissioned the first phase of its Battery Energy Storage System (BESS) project in Rajasthan, marking a significant step in India’s energy storage landscape. The company, through its subsidiaries, successfully deployed 142.67 MW / 81.49 MWh of BESS in this initial phase.
This development is part of ACME Solar’s broader plan to establish a total BESS capacity of 585 MW / 2,011.24 MWh across multiple Special Purpose Vehicles (SPVs). The newly commissioned storage systems are now connected to the operational Inter-State Transmission System (ISTS), enabling them to support the national power grid.
Initially, the BESS units will operate on a merchant basis in the short-term electricity market. The project aims to capitalize on price fluctuations between peak and off-peak hours, charging the batteries when electricity demand and prices are low and discharging during periods of high demand.
ACME Solar highlighted that these systems are designed to enhance grid reliability and optimize power utilization. By storing excess energy during low-demand periods and releasing it during peak hours, the BESS will help balance supply and demand effectively.
In the long term, the storage systems will be integrated with the company’s Firm and Dispatchable Renewable Energy (FDRE) projects and will operate under a 25-year power purchase agreement. ACME Solar’s portfolio currently anticipates around 17 GWh of battery storage installations across multiple Indian states.
