Argentina battery energy storage companies

Argentina's ambitious push toward grid modernization through battery energy storage has received an enthusiastic response, with CAMMESA (Compañía Administradora del Mercado Mayorista Eléctrico) confirming the submission of 27 project proposals from 15 companies under its AlmaGBA program.

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

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.

Argentina's 1.3 GW battery storage tender marks a transformative leap toward grid resilience and clean energy leadership in Latin America.

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.

As the opportunity to build energy storage as a reliable source in grids and to decarbonize becomes critical on a global stage, the oversubscribed tender launched by Argentina demonstrates the demand for scalable and bankable C&I energy storage systems projects, as well as the efficiency of collaborating with the government in their realization.
