300 MW FDRE Project PPA Signed

ACME Solar Holdings announced that its subsidiary, ACME Renewtech Sixth Private Limited, signed a 25-year Power Purchase Agreement with Solar Energy Corporation of India Limited for a 300 MW Firm and Dispatchable Renewable Energy project.

The project falls under SECI’s FDRE Tranche VII – Assured Peak Power Project framework. According to the company, the project includes 300 MW and 1,200 MWh Inter State Transmission System-connected assured peak power capacity. The tariff for the project has been fixed at INR 6.28 per unit. The Scheduled Commencement of Supply Date for the project is May 28, 2028.

Focus On Peak Power Supply

Under the agreement, ACME Solar will supply four hours of assured peak power during non-solar hours with a minimum annual availability requirement of 85 percent.

The company stated that the project will utilise existing night-time connectivity available at high irradiation zones. The project was awarded under SECI’s tariff-based competitive bidding process. The e-reverse auction for the tender was conducted on February 2, 2026, while the Letter of Award was issued on February 10, 2026.

Renewable Energy Portfolio Expansion
