ACME Solar Holdings Limited has reached a significant milestone in energy storage deployment, announcing the cumulative operationalization of more than 2 GWh Battery Energy Storage System (BESS) capacity in Rajasthan. The achievement, announced on April 22, 2026, positions the company among the first Indian renewable energy companies to reach this scale of energy storage deployment.

Operational Capacity Details

The company's energy storage infrastructure demonstrates substantial scale and technical capability across multiple locations in Rajasthan.

Grid Enhancement and Operational Strategy

These BESS projects serve a critical function in the power grid ecosystem, designed specifically to enhance grid reliability and optimize power utilization. The systems operate on a strategic charge-discharge cycle, storing energy during non-peak demand periods and releasing it during peak demand periods. This operational approach plays a vital role in balancing energy supply and demand while significantly improving overall grid stability.

Company Portfolio Overview

ACME Solar Holdings Limited operates as an integrated renewable energy player with a comprehensive and diversified portfolio. The company's total capacity spans 8,071 MW across multiple technologies including solar, wind, storage, FDRE and hybrid solutions.

Integrated Business Model

The company operates with an integrated approach through its in-house Engineering, Procurement, and Construction (EPC) and Operations & Maintenance (O&M) divisions. This end-to-end development and maintenance capability enables the company to deliver projects in a time and cost-effective manner while ensuring industry-leading operating performance, evidenced by superior Capacity Utilization Factor (CUF) and operating margins.

The milestone achievement in Rajasthan represents a significant step in ACME Solar's broader energy storage expansion strategy, contributing to India's growing renewable energy infrastructure and grid modernization efforts.

ACME Solar Holdings Limited has secured significant legal relief with the Hon'ble High Court of Rajasthan granting an interim stay on a GST show cause cum demand notice dated April 20, 2026. The court order provides temporary protection against the proceedings initiated by GST authorities, effectively halting the operation and effect of the show cause notice until further orders.

Court Order and Legal Relief

The Rajasthan High Court's intervention represents a favorable development in the ongoing regulatory proceedings that the company had previously disclosed to stock exchanges on March 29, 2026 and April 13, 2026. The interim stay order dated April 20, 2026, provides immediate relief by suspending the enforcement of the GST show cause cum demand notice.

Regulatory Compliance and Communication

The company has maintained full compliance with its disclosure obligations under Regulation 30 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015. Company Secretary and Compliance Officer Rajesh Sodhi formally communicated the development to both BSE Limited (Scrip Code: 544283) and National Stock Exchange of India Ltd (Symbol: ACMESOLAR) on April 20, 2026.

The communication referenced the SEBI Master Circular bearing Ref. No. HO/49/14/14(7)2025-CFD-POD2/I/3762/2026 dated January 30, 2026, ensuring adherence to all regulatory requirements for such disclosures.

Current Legal Status

The interim stay represents a significant procedural victory for ACME Solar Holdings in its dispute with GST authorities. The court's intervention provides the company with breathing room to address the regulatory concerns while preventing immediate enforcement actions.

The company continues to monitor the legal proceedings closely and has committed to providing stakeholders with timely updates as developments occur in the case. The formal documentation includes Annexure-A with detailed information as required under the listing regulations, ensuring transparency in the ongoing legal matter.
