ACME Solar Inks 450 MW Peak Power Deal with SJVN for 25 Years

Introduction

ACME Solar Holdings, a leading integrated renewable energy company in India, has solidified its market position by signing two Power Purchase Agreements (PPAs) with SJVN Limited. The agreements, executed through its subsidiary ACME Greentech Seventh Private Limited on March 2, 2026, commit to delivering a total of 450 MW of Firm and Dispatchable Renewable Energy (FDRE) for a 25-year term. This project is designed to supply 1,800 MWh of storage-backed power, specifically targeting peak demand during non-solar hours and marking a significant step in addressing the intermittency of renewable energy sources.

Details of the Agreement

The PPAs are structured as two separate contracts for 300 MW and 150 MW capacities. These were awarded under the Tranche-FDRE-4 tender, which followed Tariff-Based Competitive Bidding (TBCB) guidelines. The final tariff for the power supplied under these agreements is set at Rs. 6.74 per unit. A key feature of the deal is the commitment to provide four hours of assured peak power daily with a minimum availability of 90% on both a monthly and annual basis. This ensures a reliable power supply to the grid when it is most needed.

Project Timeline and Bidding

The journey to this agreement began with an e-reverse auction held on October 9, 2025. Following a successful bid, ACME Solar received the Letter of Award (LOA) from SJVN on November 10, 2025. The formal signing of the PPAs on March 2, 2026, finalized the contractual obligations. The project has a clear development timeline, with the Scheduled Commencement of Supply Date (SCSD) set for March 1, 2028. This provides a defined period for project construction, commissioning, and integration into the grid.

Technical and Strategic Overview

To meet the dispatchable power requirements, the project will integrate solar power generation with a substantial Battery Energy Storage System (BESS). The facility will be located in Rajasthan, leveraging the state's high solar irradiation zones to maximize energy generation. The project will connect to the national grid via Inter-State Transmission System (ISTS) substations, utilizing available night-time grid connectivity. This strategic approach not only ensures efficient power evacuation but also enhances the utilization of existing transmission infrastructure. Furthermore, this will be ACME Solar's first project to use Indian-made solar cells compliant with the Approved List of Models and Manufacturers (ALMM) List-II, aligning with national manufacturing initiatives.

Key Project Parameters

Impact on ACME Solar's Portfolio

The signing of these PPAs significantly expands ACME Solar's project pipeline. In the current financial year alone, the company has secured agreements for 1,690 MW, bringing its total PPA-signed capacity to an impressive 6,270 MW. This deal reinforces ACME's standing as a major Independent Power Producer (IPP) in India with a diversified portfolio spanning solar, wind, hybrid, and energy storage projects. The company's operational capacity currently stands at 2,918 MW, with another 4,472 MW under various stages of construction, including 13.5 GWh of BESS installations.

Market Context and Industry Significance

This agreement is indicative of a broader shift in India's renewable energy sector towards solutions that offer grid stability. FDRE projects, which combine generation with storage, are crucial for balancing the grid as the share of intermittent renewable sources grows. The competitive tariff of Rs. 6.74 per unit for assured peak power sets a new benchmark and demonstrates the increasing economic viability of large-scale energy storage solutions. The project places ACME Solar in a strong competitive position alongside other major industry players such as Tata Power Solar and Adani Solar, who are also expanding into storage and hybrid projects.

Analysis

The ACME-SJVN deal is important for several reasons. First, it directly addresses one of the primary challenges of solar power: its inability to generate electricity after sunset. By integrating 1,800 MWh of battery storage, the project can supply power during evening peak hours, enhancing grid reliability. Second, the project's location in Rajasthan is strategic, capitalizing on the country's best solar resources. Third, the 25-year PPA provides long-term revenue visibility for ACME Solar, making it an attractive proposition for investors. Finally, the project's scale and its focus on dispatchable power contribute meaningfully to India's national renewable energy targets and its goal of achieving energy security.

Conclusion

The 450 MW PPA with SJVN is a landmark agreement for ACME Solar Holdings, underscoring its expertise in developing complex, high-value renewable energy projects. By focusing on firm and dispatchable power, the company is not just adding megawatts to the grid but is also providing a crucial solution for grid stability. As the project moves towards its scheduled commissioning in March 2028, it will serve as a key asset in India's clean energy transition, demonstrating the critical role of energy storage in enabling a renewable-powered future.
