ACME Solar Holdings Limited, a front-runner in India's renewable energy revolution, has taken a monumental step in advancing the country’s green energy future. On July 7, 2025, the company announced that it has placed an order of over 3.1 GWh of Battery Energy Storage Systems (BESS), marking one of the largest such procurements in India’s energy sector to date. The systems will be sourced from reputed international suppliers, Zhejiang Narada and Trina Energy, both well-known for their high-efficiency and scalable storage technologies.

This initiative by ACME Solar signifies a powerful stride toward bolstering India’s clean energy infrastructure. The BESS units will be deployed across multiple FDRE (Firm & Dispatchable Renewable Energy) and battery-linked projects, currently under planning and execution stages. These projects are set to be commissioned within the next 12–18 months across various Indian states.

The procurement aligns with ACME Solar’s commitment to sustainable innovation, strengthening grid reliability, and delivering dispatchable clean energy in a cost-effective and technically robust manner.

Phased Implementation and Capital Efficiency

The delivery of the Battery Energy Storage Systems will follow a phased schedule, taking place over the next four to eight months within the current fiscal year. This strategy not only ensures logistical feasibility but also accelerates project readiness and revenue realization timelines.

ACME confirmed that the order was executed within its allocated capex budget, emphasizing the cost-efficiency of the procurement without compromising on the quality or performance parameters of the systems. The early acquisition of these advanced storage technologies will give the company a first-mover advantage in execution and deployment timelines, essential for grid-linked and time-sensitive power supply contracts.

Compliance with Global Standards

The ordered equipment adheres strictly to international benchmarks, including IEC (International Electrotechnical Commission) and UL (Underwriters Laboratories) standards. These certifications ensure best-in-class safety, long-term performance, and high reliability, which are crucial for managing energy flow and maintaining grid stability in India’s ever-growing renewable energy landscape.

ACME Solar emphasized that this procurement would significantly enhance its ability to offer firm and flexible power, addressing one of the key limitations of traditional solar and wind energy sources—intermittency. With the integration of battery storage into its operational model, ACME is transitioning towards delivering round-the-clock renewable power to meet the country’s growing demand.

A Leading Force in India’s Energy Transition

ACME Solar Holdings Limited has rapidly emerged as one of India’s largest integrated renewable energy platforms. Its portfolio spans 6,970 MW, which includes solar, wind, battery storage, FDRE, and hybrid energy solutions. Currently, the company boasts an operational capacity of 2,890 MW, while another 4,080 MW is in the pipeline at various stages of implementation.

ACME Solar is unique in its model, leveraging an in-house Engineering, Procurement and Construction (EPC) division, as well as its Operations and Maintenance (O&M) services, ensuring full control over project quality, timelines, and cost. This end-to-end development capability allows the company to maintain industry-leading capacity utilization factors (CUFs) and healthy operating margins, underlining its technical excellence and financial prudence.

Supporting India’s Renewable Push

India has set ambitious targets under its National Renewable Energy Mission, aiming for 500 GW of non-fossil fuel capacity by 2030. However, one of the major challenges to renewable energy scalability remains grid integration and energy dispatchability. That’s where battery energy storage systems (BESS) come into play.

By placing this historic 3.1 GWh BESS order, ACME Solar is taking a leadership position in addressing the core challenges of intermittency and grid balancing, paving the way for more resilient and responsive energy systems. Such large-scale adoption also acts as a demand signal to domestic and global manufacturers, helping drive down costs and foster technology transfer and innovation.

Collaborating with Global Technology Leaders

The collaboration with Zhejiang Narada and Trina Energy not only brings cutting-edge storage systems to Indian soil but also strengthens global partnerships in the renewable value chain. Both suppliers are internationally recognized for reliable, scalable, and cost-effective battery systems, making them ideal partners for India's energy transition.

Through this deal, ACME Solar is building an ecosystem of trust and performance, choosing vendors not only on cost but on technical excellence, reliability, and track record. This vendor strategy is crucial to ensuring zero-disruption rollouts in large-scale deployments.

Enabling Grid Stability and Clean Energy Access

The Battery Energy Storage Systems will play a crucial role in enabling grid stability, especially in regions with high renewable penetration. The stored energy can be dispatched during peak demand hours, bridging the gap between generation and consumption. This contributes directly to reducing grid volatility, minimizing curtailment, and enhancing distribution efficiency.

Additionally, BESS solutions are vital in supporting off-grid and remote area electrification, aligning with the government’s rural development and energy inclusion objectives. With ACME Solar’s presence across multiple states, these systems could also serve strategic roles in regional balancing and power deficit management.

Future-Ready Renewable Energy Solutions

With this strategic investment in energy storage, ACME Solar is not just responding to current market needs—it is future-proofing its infrastructure to serve a more dynamic, diversified, and technology-driven energy market. The synergy of FDRE, solar, wind, and battery solutions provides the company a unique edge in offering customized and reliable energy services, including ancillary support, frequency regulation, and peaking power.

Conclusion

ACME Solar’s procurement of over 3.1 GWh of Battery Energy Storage Systems marks a landmark moment in India’s renewable energy journey. It reflects a mature approach to energy infrastructure—one that prioritizes efficiency, performance, scalability, and sustainability. The order, sourced from Zhejiang Narada and Trina Energy, also reaffirms the company’s technological foresight and commitment to excellence.

As the company continues to expand its renewable footprint, this bold move will serve as a benchmark for the sector, encouraging others to adopt storage-backed renewable models. With its integrated approach, financial discipline, and robust partnerships, ACME Solar is setting the gold standard for clean energy leadership in India and beyond.
