ACME Solar Holdings Ltd today announced that its subsidiary, ACME Sikar Solar, has signed a 25-year power purchase agreement (PPA) with the Solar Energy Corp. of India (SECI) for its 300 MW solar project in Rajasthan. The PPA was signed at a fixed tariff of INR 3.05 per kWh.

This development follows the successful commissioning of the 300 MW capacity by ACME Sikar on June 23, 2025. The project was awarded under the SECI ISTS XVIII tranche, and the tariff was formally adopted by the Central Electricity Regulatory Commission (CERC) on May 30, 2025. As per the agreement, the project must commence power supply on or before June 30, 2025.

The project qualifies for the waiver of inter-state transmission system (ISTS) charges, as its scheduled commercial operation date (SCOD) falls before the June 2025 deadline—aligning with the government’s incentives for early commissioning of renewable energy projects.

With this milestone, ACME Solar’s portfolio of PPA-signed capacity now stands at 5,130 MW, of which 2,890 MW is operational and the balance is under various stages of development. In addition, the company has a firm pipeline of 1,840 MW for which Letters of Award (LOA) have been received. ACME Solar’s overall portfolio comprises 86% offtake with central government enterprises and the rest 14% with State discoms.
