This week, the Argentinian government opened bids for the AlmaGBA tender, initiated in February 2025 to procure 500 MW of battery energy storage system (BESS) capacity for critical nodes in the Buenos Aires Metropolitan Area (AMBA) grid, enhancing reliability during peak demand.
Does Argentina have a battery energy storage system?
Argentina has taken a major step toward modernizing its energy infrastructure with the launch of a 500 MW battery energy storage system (BESS) tender under the AlmaGBA program.
How many MW of battery energy storage will be deployed in Buenos Aires?
The initiative aims to deploy 500 MW of battery energy storage systems (BESS) in the Greater Buenos Aires Area (GBA), but the submitted capacity has far exceeded expectations—reaching a combined 1,347 MW
Argentina has opened a $500 million battery storage tender aimed at adding 500 MW of new energy storage capacity in the Buenos Aires metropolitan area. The AlmaGBA program, managed by CAMMESA, offers long-term contracts with fixed payments and financial guarantees to attract developers.
In Argentina, the stance provides a good lesson to the European stakeholders, especially in the commercial and industrial segments of energy storage. Emerging markets can present both local and foreign players by developing tenders that are investment appropriate and clear technically and financially secured.
Will Argentina integrate new electricity storage infrastructure into urban distribution networks?
This national and international open call, part of Resolution SE 67/2025, marks Argentina's first large-scale effort to integrate new electricity storage infrastructure into urban distribution networks.
Buenos Aires, with its dense urban load and aging infrastructure, is an ideal candidate for such an upgrade. Moreover, this tender arrives at a time when battery prices are becoming increasingly competitive, and international developers are actively seeking new markets with clear regulatory frameworks and stable revenue models.
