ACME Solar Wins Maiden Standalone BESS Project for NHPC in Andhra Pradesh

In a significant milestone for ACME Solar Holdings, the company has emerged as the successful bidder for NHPC’s tender to develop standalone Battery Energy Storage System (BESS) projects in Andhra Pradesh. 

ACME Solar's Winning Bid

The awarded project is part of a tender floated by NHPC for BESS capacity allocation. With a cumulative size of 275 MW and a storage capacity of 550 MWh, the project represents a crucial shift for ACME Solar into grid-scale energy storage solutions.

The winning bids were for the Kuppam and Ghani projects. Here are the details of the 2 projects:

• Kuppam Project: ACME Solar’s bid was ₹2,10,000 per MW per month for a 50 MW/100 MWh project.
  
   
• Ghani Project: The winning bid stood at ₹2,22,000 per MW per month for a 225 MW/450 MWh project.

These projects will require system availability for 2  full operational cycles of 2 hours each every day, further strengthening ACME Solar’s position in energy storage.

Financial Support and Viability Gap Funding

As part of the project, ACME Solar will receive viability gap funding (VGF) of ₹27 lakh per MWh or 30% of the total project cost, whichever is lower. This financial support will enhance the company's ability to implement these large-scale storage systems efficiently and cost-effectively.
