ACME Solar Holdings has signed a landmark 25-year power purchase agreement with NHPC Limited, signaling a strategic leap in India’s renewable energy landscape. Under this agreement, ACME will deliver 250 MW of firm and dispatchable renewable energy (FDRE) from its Rajasthan project at a tariff of Rs. 4.56 per kWh. The project, which integrates solar, wind, and battery storage technologies, is designed to supply at least 40% Capacity Utilization Factor (CUF) annually while fulfilling 90% of peak power demand for four hours daily. This agreement elevates ACME’s PPA-secured portfolio to 5,130 MW, further reinforcing its leadership in clean energy innovation.
A Strategic Alliance in India’s Energy Transformation
In a significant development for India’s renewable energy sector, ACME Solar Holdings Ltd. has entered into a long-term power purchase agreement (PPA) with NHPC Limited, a central government enterprise with a AAA credit rating. This 25-year agreement marks a pivotal milestone in the evolution of firm and dispatchable renewable energy (FDRE) in the country.
The agreement covers the supply of 250 megawatts of renewable power from ACME’s Rajasthan-based project. Notably, the PPA has been finalized at a competitive tariff of Rs. 4.56 per kilowatt-hour. The energy will be delivered with a minimum annual Capacity Utilization Factor of 40% and will meet 90% of peak demand for a four-hour daily window — aligning well with India's energy security goals.
Leveraging Hybrid Technologies for Reliable Power Supply
What sets this initiative apart is its hybrid architecture. The Rajasthan project is designed to deliver reliable and consistent power through a mix of solar, wind, and advanced battery storage systems. This integrated model ensures that renewable energy can be dispatched on demand, addressing the intermittency challenges that often accompany green energy solutions.
The project will be connected to the Inter-State Transmission System (ISTS), and connectivity infrastructure is already in place. This assures seamless integration with the national grid, enhancing the system’s overall stability and capacity to manage renewable inflows.
Approval for tariff adoption under Section 63 of the Electricity Act, 2003, was granted by the Central Electricity Regulatory Commission (CERC) on June 19, 2025 — clearing the regulatory pathway for project execution.
Expanding Renewable Footprint and Portfolio Strength
With the inclusion of this project, ACME Solar’s PPA-secured capacity now stands at 5,130 MW, of which 2,826.2 MW is already operational. The remaining capacity is progressing through various phases of development and implementation. This robust pipeline reflects the company’s strategic foresight and operational resilience in a rapidly evolving energy market.
ACME’s portfolio distribution highlights a strong preference for sovereign counterparties, with 86% of its offtake agreements signed with central government entities and the remaining 14% contracted with state discoms. Such a mix not only ensures credit stability but also reflects the company’s institutional credibility.
A Leading Player in India’s Green Energy Revolution
As one of India’s most diversified renewable energy players, ACME Solar operates a portfolio of 6,970 MW across solar, wind, FDRE, and hybrid power solutions. The company’s commitment to innovation and sustainable energy infrastructure positions it as a critical contributor to India’s clean energy transition.
This latest agreement with NHPC underscores ACME’s growing prominence in the firm renewable energy segment — a space that is expected to gain increasing importance as India targets 500 GW of non-fossil fuel capacity by 2030.
Conclusion
The collaboration between ACME Solar and NHPC represents more than just another energy agreement — it is a benchmark for the future of reliable, clean power in India. By combining cutting-edge hybrid technologies with long-term policy support and institutional partnerships, this initiative sets the tone for the next phase of India’s energy evolution. As the global spotlight increasingly focuses on climate resilience and sustainable growth, projects like these are not only strategic — they are imperative.
