Project Details

ACME Solar Holdings has executed a Power Purchase Agreement (PPA) with Solar Energy Corporation of India Limited (SECI) for a 300 MW/1200 MWh capacity under the Firm and Dispatchable Renewable Energy (FDRE) Tranche VII – Assured Peak Power Project. The agreement was signed through the company's wholly-owned subsidiary, ACME Renewtech Sixth Private Limited, securing a tariff of ₹6.28 per unit for a project tenure of 25 years. The Scheduled Commencement of Supply Date (SCSD) is set for May 28, 2028. This development raises the company's PPA-signed portfolio to 6,570 MW out of a total contracted portfolio of 8,070 MW.

The project was awarded under SECI's FDRE Tranche-VII tender, following a Letter of Award (LOA) dated February 10, 2026. The tender was conducted under Tariff-Based Competitive Bidding (TBCB) guidelines, with an e-reverse auction held on February 02, 2026. The executed PPA covers a contracted capacity of 300 MW, a reduction from the 301 MW capacity initially referenced in the LOA — a change mutually agreed upon for the optimisation of project configuration and implementation.
