ACME Solar Holdings announced that its wholly-owned subsidiary, ACME Sun Power Private Limited, has commissioned new Battery Energy Storage System (BESS) capacity. The newly added capacity totals 33.333 MW with a storage capability of 160.484 MWh. This new facility is located in Rajasthan. The project's Commercial Operation Date (COD) is set for May 13, 2026.
This expansion significantly boosts ACME Solar's infrastructure within the fast-growing renewable energy sector, particularly for grid-scale energy storage. By increasing its BESS capacity, the company is better positioned to manage the intermittent nature of solar power and deliver more stable energy solutions to the grid.
ACME Solar Holdings is part of the ACME Group, a prominent force in India's solar energy market. The group has been strategically growing its BESS capabilities, recognizing energy storage as vital for the ongoing renewable energy transition. Over the past two years, ACME Group has secured considerable funding, including a $270 million deal in late 2023, specifically for its large-scale BESS projects. This underscores a clear strategy to build a strong energy storage portfolio alongside its existing solar assets.
Following this commissioning, ACME Solar Holdings has increased its operational BESS capacity by over 33 MW. The company's total operational BESS capacity now exceeds 233 MW. This development strengthens ACME Solar's role as a provider of integrated renewable energy and storage solutions, supporting grid stability and the integration of renewables in Rajasthan.
However, revenue generation from this newly commissioned capacity is dependent on the commencement of commercial operations on May 13, 2026. The renewable energy sector can also encounter project execution delays due to factors such as regulatory approvals and supply chain issues.
ACME Solar's expansion places it in a dynamic BESS market. Competitors like Tata Power and Adani Green Energy are also making substantial investments in renewable capacity and energy storage. Sterling and Wilson Renewable Energy, a major solar EPC provider, operates within the broader renewable infrastructure space.
For context, ACME Solar's total commissioned capacity, combining solar and BESS, was 1,200 MW as of fiscal year 2024. The company reported approximately 15% year-on-year revenue growth in FY24.
Investors will be watching for the formal commencement of commercial operations for the new 33.333 MW BESS project on May 13, 2026. Monitoring performance data once the capacity is operational, tracking further announcements on ACME's BESS pipeline or funding, and observing progress in integrating BESS with solar generation assets will also be key.
