Argentina Battery Storage Auction Draws Bids as Low as $7,397/MW-Month: 11x Oversubscribed
Argentina's first large-scale battery storage auction has delivered dramatic results, with 37 companies submitting 232 proposals totaling 8,230 MW of proposed capacity—more than 11 times the 700 MW procurement target. The Argentina battery storage auction, known as AlmaSADI, attracted financial bids ranging from $7,397/MW-month to the auction ceiling of $12,500/MW-month, with a weighted average of $10,568.4/MW-month, approximately 15.5% below the maximum price.

AlmaSADI Auction: Breaking Down the Numbers
The competitive intensity revealed in the financial bid opening is remarkable for a first-of-its-kind procurement in Latin America. With 8,230 MW of proposed capacity against a 700 MW target, developers clearly view Argentina as a high-priority market for grid-scale battery energy storage systems (BESS). The weighted average price of $10,568.4/MW-month suggests that even at this early stage, Argentina's storage market is pricing competitively.
Weighted average prices showed meaningful regional variation. The Central San Luis region recorded the lowest at $9,916.7/MW-month, while the northeast Chaco and Formosa region posted the highest at $11,194.3/MW-month. These differences reflect varying levels of competition across Argentina's network nodes—a pattern familiar to markets with geographically dispersed transmission infrastructure.
What the AlmaSADI Tender Seeks to Achieve
The tender aims to deploy battery storage at critical grid nodes spanning Argentina's northwest, northeast, central, littoral, Cuyo, Pampas, and Buenos Aires regions—excluding the Buenos Aires metropolitan area. Each facility must deliver at least four consecutive hours of discharge to provide both capacity and operating reserve services in Argentina's wholesale electricity market.
Argentina's Energy Secretariat estimates the procurement could support approximately $700 million in total investment, making this one of the most ambitious single storage procurements in Latin American history. The economic benefits extend beyond grid reliability—new construction jobs, supply chain development, and technology transfer all factor into the broader value proposition.
How Winners Will Be Selected
Market operator CAMMESA will evaluate bids using a multi-factor methodology rather than simply selecting the lowest price. Bid prices, regional capacity limits, and nodal allocation rules all play a role. This balanced approach is designed to ensure that storage capacity is deployed where it delivers maximum system value, not just where it costs the least.
Argentina's Energy Transition Context
Argentina possesses world-class renewable energy resources—particularly wind in Patagonia and solar in the northwest—but has historically struggled with grid infrastructure constraints. Battery storage offers a way to unlock these resources without waiting for multi-billion-dollar transmission projects. By positioning storage at critical nodes, Argentina can increase renewable penetration, reduce curtailment, and improve overall system reliability.
The AlmaSADI auction also positions Argentina alongside neighboring Chile, which has already emerged as a regional storage leader. Together, these two markets could create a Southern Cone storage corridor that attracts global manufacturers, developers, and financiers seeking to establish a foothold in the rapidly growing Latin American market.
What Comes Next
With financial bids now opened, CAMMESA will proceed to evaluate and allocate capacity according to the tender rules. Projects that secure awards will need to move through permitting, financing, and construction—a multi-year process that will test Argentina's regulatory efficiency and project finance ecosystem.

The AlmaSADI results send an unmistakable signal: Latin America's battery storage revolution is not coming—it has already arrived, and Argentina intends to be at its center.
