ACME Solar Signs 25‑Year PPA for 300 MW Assured Peak Power Project

The contract locks in four hours of non‑solar peak supply at Rs 6.28 per unit and raises ACME’s contracted dispatchable storage capacity ahead of a 2028 start date.

Overview

  • ACME executed the 25‑year Power Purchase Agreement through its subsidiary for a 300 MW / 1,200 MWh ISTS‑connected Firm and Dispatchable Renewable Energy (FDRE) project, with the Scheduled Commencement of Supply Date set for May 28, 2028.
  • The PPA fixes a tariff of Rs 6.28 per unit and requires ACME to deliver four hours of assured peak power during non‑solar hours each day while meeting a minimum annual availability of 85 percent.
  • The project was won under SECI’s FDRE Tranche‑VII after an e‑reverse auction and Letter of Award process earlier this year, reflecting India’s tariff‑based competitive procurement for dispatchable renewables.
  • With this signing ACME’s PPA‑signed portfolio rises to 6,570 MW of its 8,070 MW contracted pipeline, and the company reports roughly 2.7 GWh of operational BESS plus large additional BESS capacity under construction.
  • By using ISTS connections and existing night‑time connectivity at high‑irradiation zones, the project aims to supply firm evening peak power and may help reduce grid stress and the need for fossil fuel backup when solar generation ends.
