ACME Solar Holdings, through its wholly owned subsidiaries, secured the projects via an e-reverse auction conducted on 24 June 2025. The contracts include 50 MW / 100 MWh at a tariff of Rs 2,10,000 per MW per month, and 225 MW / 450 MWh at Rs 2,22,000 per MW per month.

The Letter of Award (LoA) was issued on 8 July 2025. The quick transition from LoA to signing was facilitated by the prior identification of the customer—Andhra Pradesh. The battery installations will be set up at the customer's site, with land and evacuation infrastructure provided by them, which is expected to accelerate execution.

These projects, expected to be commissioned within 18 months, are among the first of their kind in the state. They aim to support grid stability by storing energy during off-peak hours and releasing it during peak demand, aiding the integration of renewable sources such as solar and wind.

The project follows a "BESS as a Service" model, where capacity charges are applicable. With the addition of these standalone BESS assets, ACME Solar strengthens its portfolio by leveraging large-scale battery procurement and deployment efficiencies.
