ACME Solar Holdings Limited has secured a major win by emerging as the successful bidder for NHPC’s standalone Battery Energy Storage System (BESS) projects in Andhra Pradesh. The total awarded capacity is 275 MW / 550 MWh across two locations — Kuppam and Ghani.
For the Kuppam project, ACME Solar’s winning tariff was ₹2,10,000 per MW per month. This project will have a capacity of 50 MW / 100 MWh. For the Ghani project, the company bid ₹2,22,000 per MW per month for a larger capacity of 225 MW / 450 MWh.
These BESS projects are designed for two full operational cycles of two hours each per day, ensuring consistent energy storage and availability. As per the tender guidelines, ACME Solar is also eligible for viability gap funding of ₹27 lakh per MWh or 30% of the total project cost — whichever is lower.
This win marks a significant milestone for ACME Solar, as it steps into the standalone energy storage space for the first time. The company already has a diversified renewable energy portfolio, including solar, wind, FDRE, and hybrid projects.
The tender was floated by NHPC in February 2025 with an aim to enhance grid stability and storage capacity in Andhra Pradesh, paving the way for greater renewable energy integration.
With this addition, ACME Solar continues to cement its position as a leading player in India’s clean energy transition.
