ACME Solar Holdings has achieved a significant milestone by commissioning 142.67 MW / 481.49 MWh of Battery Energy Storage System (BESS) in Rajasthan. This represents the completion of phase-1 under the company's ambitious energy storage expansion plan.

Project Specifications and Capacity

The commissioned BESS facility forms part of a larger strategic initiative by the renewable energy company. The project details are outlined below:

Operational Strategy and Revenue Model

The BESS facility is strategically positioned to operate on a merchant basis initially, capitalizing on price differentials between peak and non-peak demand hours. This approach allows the company to generate additional revenue streams through optimized energy trading. The system is designed to charge batteries during periods of low demand and discharge during peak demand periods, enhancing grid reliability and power utilisation efficiency.

Eventually, these storage systems will be integrated with respective Firm and Dispatchable Renewable Energy (FDRE) projects, which will then continue under Power Purchase Agreements (PPA) for 25 years, providing long-term revenue stability.

Company Portfolio and Future Expansion

ACME Solar Holdings maintains a comprehensive renewable energy portfolio with significant scale and diversity:

The company's overall portfolio requires installation of approximately 17 GWh of BESS across multiple phases in different states, indicating substantial growth potential in the energy storage segment.

Grid Stability and Infrastructure Benefits

The commissioned BESS facility plays a critical role in balancing energy supply and demand while improving overall grid stability. These systems are specifically designed to enhance grid reliability through intelligent charging and discharging cycles that respond to demand patterns. The connection to the existing operational Inter-State Transmission System ensures seamless integration with the broader power infrastructure.

ACME Solar Holdings operates with an integrated business model featuring in-house Engineering, Procurement, and Construction (EPC) and Operations & Maintenance (O&M) divisions. This end-to-end approach enables the company to deliver projects in a time and cost-effective manner while maintaining industry-leading Capacity Utilization Factor (CUF) and operating margins.

ACME Solar Holdings has officially commissioned the second phase of its Battery Energy Storage System (BESS) project through its wholly owned subsidiary ACME Sun Power Private Limited, marking a significant milestone in the company's renewable energy expansion.

Project Commissioning Details

The company announced the commissioning of the second phase under Regulation 30 of SEBI listing requirements, with specific operational parameters and timeline.

Cumulative Project Progress

With the commissioning of the second phase, ACME Sun Power Private Limited has achieved substantial progress toward the total project capacity.

Strategic Infrastructure Development

The BESS project represents a critical component of India's renewable energy infrastructure, providing grid stability and energy storage capabilities. The project's location in Rajasthan positions it strategically within one of India's leading renewable energy states.

The successful commissioning follows the company's previous intimation dated March 06, 2026, demonstrating ACME Solar Holdings' ability to execute large-scale energy storage projects according to planned timelines. This achievement reinforces the company's commitment to advancing battery energy storage technology and supporting grid modernization initiatives.
