ACME Solar wins 50 MW in Tata Power FDRE auction

• ACME Solar secures 50 MW in Tata Power’s FDRE auction, winning a 25-year PPA to deliver hybrid solar-storage power with 90% peak-hour availability.

Indian renewable energy developer ACME Solar Holdings Ltd (BOM:544283) has secured 50 MW of capacity in a competitive 250-MW Firm and Dispatchable Renewable Energy (FDRE) auction organized by Tata Power’s distribution arm.

The developer confirmed it has received a letter of award (LOA) for the allocation at a tariff of INR 4.43 (USD 0.050/EUR 0.043) per kWh. The reverse e-auction was conducted on August 13, 2025, marking another milestone in India’s transition toward flexible renewable energy supply.

Under the agreement, ACME Solar will move forward to sign a 25-year power purchase agreement (PPA) with Tata Power. Once the contract is finalized, the company will have 24 months to commission the project. The awarded capacity is expected to integrate solar generation with battery energy storage systems (BESS) and potentially other renewable sources to meet dispatchable energy requirements.

The FDRE structure places strict performance obligations on developers. ACME will need to guarantee four hours of peak-hour supply with at least 90% monthly availability, ensuring grid reliability and addressing intermittency challenges often linked to renewable energy.

This award builds on ACME Solar’s position as one of India’s leading renewable energy companies. The developer, which also provides EPC and operations and maintenance services, already manages an operational portfolio of 2,890 MW spanning solar, wind, storage, and hybrid projects.

India has been ramping up efforts to incentivize dispatchable renewable capacity, aligning with its target of 500 GW of non-fossil fuel capacity by 2030. Hybrid projects with storage are seen as a cornerstone in ensuring round-the-clock renewable supply while reducing reliance on coal.

For ACME Solar, the win not only expands its renewable portfolio but also reinforces its strategy of leveraging hybrid and storage-backed solutions to deliver firm green power to utilities and industrial consumers.
