Gurugram: ACME Solar Holdings Ltd has signed a 25-year power purchase agreement (PPA) with NHPC Limited for its 250 MW Firm and Dispatchable Renewable Energy (FDRE) project in Rajasthan, the company announced on Friday. The project marks a major milestone in ACME Solar’s growing presence in hybrid clean energy solutions, leveraging a combination of solar, wind, and battery storage, said the company.
The agreement, signed at a tariff of Rs 4.56 per kilowatt-hour (kWh), stipulates a minimum annual Capacity Utilisation Factor (CUF) of 40 percent and requires the delivery of 90 percent of peak power needs over a four-hour daily window.
The project will be connected to an Inter-State Transmission System (ISTS) substation, with connectivity already secured. The Central Electricity Regulatory Commission (CERC) granted approval for tariff adoption under Section 63 of the Electricity Act, 2003 on June 19, 2025, in Petition No. 87/AT/2025 filed by NHPC.
ACME Solar said the project will enhance its capabilities in the FDRE segment while contributing to India’s clean energy goals. “This PPA marks a significant step in strengthening ACME Solar’s footprint in the FDRE space while supporting India’s clean energy ambitions through an innovative mix of solar, wind, and battery storage technology,” the company said in a statement.
With this agreement, ACME Solar’s total portfolio of PPA-signed projects now stands at 5,130 MW. Of this, 2,826.2 MW is already operational, with the remaining capacity under various stages of development. The company also has a 1,840 MW project pipeline for which Letters of Award (LoA) have been received.
According to the company, 86 percent of its offtake agreements are with central government enterprises, with the remaining 14% tied to state distribution companies.
