ACME Solar Holdings Ltd has secured a 400 MW firm and dispatchable renewable energy project from SJVN Limited under the FDRE-IV tender, marking a pivotal step in India’s transition toward round-the-clock clean power. The 25-year contract, awarded at a tariff of ₹6.75 per unit, combines 300 MW of solar generation with 1,800 MWh of battery energy storage, enabling ACME to supply firm power during peak demand hours. The project underscores the growing importance of storage-linked renewables in stabilizing India’s electricity grid and enhancing reliability across the power value chain.
Project Overview and Key Terms
ACME Solar emerged as a winning bidder under the Firm and Dispatchable Renewable Energy (FDRE-IV) tender conducted by SJVN Limited. The company will supply power generated from a hybrid configuration—300 MW of solar capacity integrated with a 1,800 MWh Battery Energy Storage System (BESS).
Under the terms of the agreement, ACME will deliver 4 MWh of electricity per MW of capacity during any designated four-hour peak period each day, ensuring a minimum monthly availability of 90 %. The project is structured under a 25-year power purchase agreement (PPA), providing long-term revenue visibility and stability.
The tender’s final tariff of ₹6.75 per kWh represents one of the most competitive bids in the dispatchable renewables category—highlighting the cost efficiency achieved through integrated solar-storage systems.
Strategic Importance for ACME Solar
The project reinforces ACME Solar’s position as a leading player in India’s evolving renewable energy landscape. By leveraging its existing transmission connectivity in Rajasthan, the company will optimize infrastructure usage and accelerate commissioning timelines.
ACME’s portfolio now includes more than 2.9 GW of operational capacity and an additional 4.4 GW under construction, including 13.5 GWh of energy storage projects. This win also aligns with the company’s strategy to diversify its portfolio toward firm renewable power, moving beyond traditional solar installations that depend on intermittent sunlight.
The project is particularly significant as it positions ACME in a segment gaining traction among distribution companies (DISCOMs) that increasingly demand firm, reliable clean power instead of variable generation.
Sectoral Context: India’s Push for Round-the-Clock Renewables
India’s renewable energy policy has been shifting from merely expanding capacity to ensuring grid reliability and dispatchable power. As the share of solar and wind energy rises, balancing supply during evening peaks has become a major challenge.
Projects such as ACME’s hybrid solar-storage venture address this challenge by providing on-demand clean electricity—a key component of India’s decarbonization strategy. The FDRE model, introduced by the Ministry of New and Renewable Energy (MNRE), allows developers to blend renewable generation with battery systems to meet firm supply obligations.
At a tariff of ₹6.75 per unit, the bid demonstrates that storage-enabled renewables are becoming commercially viable, narrowing the gap between conventional and green power sources.
Execution Challenges and Outlook
While the project represents a milestone in India’s renewable trajectory, it also poses execution challenges. The large-scale deployment of battery storage at 1,800 MWh requires substantial capital investment, sophisticated technology integration, and strong supply chain coordination.
Ensuring system performance, battery life, and grid synchronization will be critical to maintaining contractual obligations. Moreover, the project’s success depends on managing fluctuations in global module and battery prices, financing costs, and regulatory frameworks.
Nevertheless, ACME’s established expertise in large-scale solar projects and its experience in developing hybrid systems offer confidence in successful execution.
Implications for India’s Energy Transition
The ACME-SJVN agreement marks a transformational shift in India’s renewable energy market—symbolizing the move from capacity addition to reliability-driven clean energy solutions. As more utilities and developers adopt FDRE and RTC (round-the-clock) models, India is likely to witness faster adoption of grid-scale storage systems and hybrid energy frameworks.
For investors, this evolution signals the emergence of new value pools in renewable infrastructure—particularly in storage integration, ancillary services, and grid flexibility markets.
ACME’s 400 MW project is not just a business milestone but also a proof of concept for India’s next phase of energy transition—where clean power becomes as reliable as conventional sources, yet economically competitive.
