ACME Solar Expands Rajasthan Energy Storage With 33MW Phase V

ACME Solar Holdings Ltd. announced the commissioning of its fifth phase of the Battery Energy Storage System (BESS) project in Rajasthan. This new phase adds 33.334 MW of capacity and 160.48 MWh of storage. The Commercial Operation Date (COD) for this phase is set for April 8, 2026.

Project Progress and Scale

This development brings the project's total commissioned capacity to 166.670 MW/802.460 MWh. The Rajasthan BESS project is planned for a total of 300 MW/1409.34 MWh.

Strategic Importance for Grid and Growth

This expansion is a key step in ACME Solar's strategy to integrate storage with its renewable energy portfolio. It supports India's expanding energy storage infrastructure, vital for stabilizing the grid and managing variable sources like solar and wind power. The successful commissioning demonstrates ACME Solar's execution capability and strengthens its market position.

Company Background and Financials

ACME Solar is a significant player in India's renewable energy sector. The company has been actively increasing its BESS capacity, with multiple project phases commissioned around early 2026. Financially, ACME Solar reported strong operational performance for the six months ending April 5, 2026, showing substantial year-on-year growth in revenue and profit after tax. The company bolstered its financial flexibility by raising approximately ₹2,900 crore through an IPO in November 2024.

Operational and Market Impact

This increase in operational BESS capacity will contribute to revenue generation and grid support services. It further solidifies ACME Solar's standing in India's energy storage market and demonstrates its ability to develop and commission complex projects, moving closer to its overall renewable and BESS capacity targets.

Competitive Landscape

ACME Solar operates in a competitive landscape with peers such as NHPC Ltd. and SJVN Ltd., which are also expanding their renewable and storage capacities in India. Other major players like NTPC Ltd. (through NTPC Green Energy) and NHPC are developing solar, wind, and hydro projects, while also exploring storage solutions.

Key Performance Indicators

Key performance indicators reported for the six months ending April 5, 2026, include a 58.49% consolidated revenue growth and a 68.07% consolidated profit after tax (PAT) growth. The Rajasthan BESS project's total planned capacity is 300 MW / 1409.34 MWh, with 166.670 MW / 802.460 MWh now commissioned as of April 8, 2026.

Looking Ahead

Investors will be watching the commissioning of the remaining phases of the 300 MW BESS project. ACME Solar's broader energy storage and renewable energy expansion pipeline, as well as financial updates reflecting new capacities, will also be key indicators. Developments in energy storage market policies and the integration of BESS with Firm and Dispatchable Renewable Energy (FDRE) projects will be important to monitor.
