The opening of financial bids has confirmed a trend that had already begun to emerge globally: the increasing competitiveness of Battery Energy Storage Systems (BESS).

Some key highlights include:

• A total of 232 bids were submitted by 37 companies.
• Offered capacity reached 8,338 MW against an initial procurement target of 700 MW.
• The lowest bid price was US$ 7,397/MW-month, 27% below the minimum price awarded under the AlmaGBA tender.
• The contracting framework through CAMMESA introduces conditions that could enhance project bankability compared to previous procurement processes.

Beyond the awards expected in the coming days, the tender has already delivered a clear signal: energy storage is becoming an increasingly competitive solution for strengthening the reliability of Argentina’s power system.

At BA Energy Solutions, we have analyzed the key outcomes of both tenders and their implications for the development of Argentina’s energy storage market.
