Argentina’s storage tender receives 235 bids for more than 8.3 GW

On Wednesday, the Argentine government opened the technical bids for the Alma SADI national and international open tender for energy storage projects. The goal is to incorporate battery storage facilities at critical nodes in the Northwest, Northeast, Central, Litoral, Cuyo, and Buenos Aires regions (excluding the Greater Buenos Aires metropolitan area). This initiative will strengthen the reliability of the Argentine Interconnected System (SADI) and reduce service interruptions, especially during peak demand.

In this context, 235 projects from 37 companies were presented, for a total of 8,335 MW, 12 times more (+1,090%) than the 700 MW that had been established as the target power in the tender. 

After receiving the bids, CAMMESA (Compañía Administradora del Mercado Mayorista Eléctrico) in Argentina will evaluate them, and the results will be published on June 16, prior to the opening of the financial bids, scheduled for June 24. The awarding of the bids is expected in early July. CAMMESA estimates that this first stage will require an investment of US$700 million to reach the target of 700 MW, or US$1 million per megawatt.

The measure builds on the precedent of the Greater Buenos Aires Storage Project (ALMA-GBA), Argentina’s first large-scale energy storage initiative, which was completed in early September of last year. In that project, the National Government awarded 713 MW of storage capacity at critical nodes in the Buenos Aires Metropolitan Area (AMBA), exceeding the initial target by more than 40%, with an estimated investment of over USD 540 million. The necessary infrastructure work for its commissioning is currently underway.

The International Renewable Energy Agency, IRENA, estimates that the photovoltaic power installed in Argentina in 2025 was 1,741 MW.
