ACME Solar Holdings won the bid for NHPC’s tender for cumulative capacity of 275 MW / 550 MWh standalone Battery Energy Storage System (BESS) projects in Andhra Pradesh across two projects at Kuppam and Ghani.

The company’s winning bid for Kuppam project was at a tariff of ₹2,10,000 per MW per month with a capacity of 50 MW / 100 MWh. 

The second bid won was for the Ghani project at a tariff of ₹2,22,000 per MW per month with a capacity of 225 MW / 450 MWh.

The project requires system availability for two full operational cycles of two hours each every day. 

As part of the project, ACME Solar will receive viability gap funding of ₹27 lakh per MWh or 30 per cent of the total project cost, whichever is lower.

This milestone further diversifies ACME Solar’s portfolio to include maiden standalone BESS projects in its existing portfolio of solar, wind, FDRE & hybrid renewable energy projects. 

The auction was part of a tender issued by NHPC in February 2025 to enhance energy storage capacity in Andhra Pradesh.
