Argentina Receives 232 BESS Bids in 700 MW AlmaSADI Tender

Argentina received 232 qualified proposals from 37 companies in the AlmaSADI battery storage tender, totaling 8,230 MW, more than 11 times the 700 MW target that wholesale electricity market operator CAMMESA will award on July 8.

Argentina's Secretariat of Energy confirmed on June 25 the opening of the economic envelopes for the tender, launched in March under Resolution SE 50/2026. Bids, based on figures reported by pv magazine using CAMMESA data, range from $7,397 to $12,500 per MW-month, with a weighted average of $10,568 per MW-month, equivalent to 15.5 percent below the ceiling price set in the tender documents. The estimated investment for this first phase is approximately $700 million. The 8,230 MW on offer represent a potential investment of nearly $8.2 billion, according to the Secretariat of Energy.

AlmaSADI is the country's second major storage tender, following AlmaGBA, which awarded 713 MW in the Buenos Aires metropolitan area. In this round, CAMMESA acts as direct buyer under contracts of up to 15 years. Systems must deliver at least four consecutive hours of discharge and reach commercial operation by December 2029 at the latest. The regions with the highest concentration of bids were Buenos Aires province (1,960 MW across 42 projects), the NEA region covering Chaco and Formosa (1,790 MW across 62 projects), and the NOA region (1,435 MW across 37 projects). Proposals were also submitted for the Litoral, Centro, Cuyo, and La Pampa regions. Among the bidders with the highest probability of being awarded, according to CAMMESA's preliminary simulation as reported by pv magazine, are Genneia with 421 MW across seven projects, DQD Energy with 162 MW across eight projects, and 360Energy with 73 MW across three projects.

AlmaSADI's price levels establish a cost benchmark for battery storage tenders across Latin America. The July 8 award of 700 MW will set the final pricing for the region's first national-scale battery storage tender and will shape the trajectory of subsequent rounds in Argentina and neighboring countries.
