ACME Solar Holdings Ltd commissioned 142.67 MW / 481.49 MWh of Battery Energy Storage System (BESS) capacity in Rajasthan. The project marks the first phase of the company’s large-scale energy storage initiative, which will be implemented through multiple special purpose vehicles. This installation represents an important milestone in ACME Solar’s strategy to expand its energy storage infrastructure alongside renewable energy capacity.
Part of a Larger 585 MW Storage Plan
The newly operational facility forms part of the company’s planned battery storage capacity of 585 MW / 2011.24 MWh across several project entities. Over time, the company intends to significantly scale up these installations to support its growing renewable energy portfolio. According to ACME Solar, its expanding renewable assets will ultimately require around 17 GWh of battery energy storage capacity across different phases and locations in India.
Connected to the Inter-State Transmission Network
The commissioned BESS facility is connected to the Inter-State Transmission System (ISTS) network, allowing it to support power flow across the national grid. Initially, the project will operate on a merchant basis. Under this model, the company will generate revenue by leveraging the price differences between peak and non-peak electricity demand periods.
Energy Storage Supports Grid Balancing
Battery energy storage systems function by charging during periods of low electricity demand and discharging power when demand rises. As a result, they help stabilize electricity supply and improve grid efficiency. This operating model not only enables ACME Solar to optimize power utilization but also contributes to better grid balancing, particularly as renewable energy generation continues to expand.
Critical Infrastructure for Renewable Energy Growth
As India rapidly increases renewable energy capacity, energy storage solutions are becoming essential. BESS infrastructure helps manage fluctuations in renewable generation, especially from solar and wind sources. By storing surplus electricity and releasing it when required, battery systems enhance grid reliability and energy security.
Integration with Long-Term Renewable Projects
As reported by manufacturingtodayindia.com, ACME Solar plans to integrate these battery storage assets with its Firm and Dispatchable Renewable Energy (FDRE) projects. Once integrated, the combined projects will operate under long-term power purchase agreements (PPAs) with a tenure of 25 years. Through this strategy, the company aims to create a stable and dispatchable renewable power supply, supporting India’s transition toward a more resilient and sustainable energy system.
