Acme Solar Holdings, through its special purpose vehicle (SPV), has signed a 25-year Power Purchase Agreement (PPA) with Tata Power Company (Tata Power-D) for its 50 MW Firm and Dispatchable Renewable Energy (FDRE) project. The agreement was finalised on 16 October 2025, following the Letter of Award issued in September 2025.

The PPA has been signed at a tariff of Rs 4.43 per unit, with a minimum annual Capacity Utilisation Factor (CUF) of 40 per cent. It also requires four hours of peak-hour supply each month with a minimum 90 per cent availability.

The project will integrate multiple renewable energy technologies — including solar and Battery Energy Storage Systems (BESS) — to ensure a firm and reliable supply of clean power in line with the terms of the agreement.

With this latest development, Acme Solar has now signed PPAs for a cumulative capacity of 600 MW of renewable energy and 550 MWh of standalone BESS projects during the current financial year.

The company said the agreement with Tata Power marks another step towards strengthening India’s dispatchable renewable energy framework, combining generation stability with storage-based flexibility to meet grid demand efficiently.
