Argentina’s Aluar to Invest $50 Million in Battery Storage
Argentina · Energy
Key Facts
—The Investor Aluar Aluminio Argentino S.A.I.C. is Argentina’s only aluminum producer, making this a strategic industrial energy play rather than a standalone utility venture.
—The Location The battery system will be built in Goya, within the NEA region, serving a critical grid node for the Corrientes and Misiones provinces.
—The Capacity The new Goya project will provide 50 MW of power with a 250 MWh storage size, helping to manage peak demand and stabilize frequency.
—The Tender Aluar was awarded the contract under the government’s AlmaSADI program, designed to restore operating reserves in the Argentine Interconnection System (SADI).
—The Big Picture The project is part of a broader 700 MW national push, attracting an estimated US$700 million in total battery storage investments across Argentina.
Argentina’s sole aluminum producer Aluar is advancing into the energy sector with a US$50 million battery storage investment in Corrientes, strengthening the industrial power backbone of the country.
The Goya Battery Energy Storage Project
Aluar Aluminio Argentino S.A.I.C. will develop a Battery Energy Storage System (BESS) in the city of Goya, located in the province of Corrientes. The facility is designed to deliver 50 megawatts (MW) of power with a substantial storage capacity of 250 megawatt-hours (MWh).
The project was officially awarded to the aluminum producer on July 7, 2026, under the AlmaSADI tender program. This federal initiative aims to deploy storage technology at critical nodes of the Argentine Interconnection System (SADI), specifically targeting the NEA region, which includes service to both Corrientes and Misiones.
To understand why Goya was chosen, it helps to know that the Argentine Interconnection System functions like a national highway for electricity. Some stretches, particularly in the northeast, experience congestion and voltage drops during periods of high demand.
Placing a battery at a critical node allows grid operators to smooth out those fluctuations without firing up distant, less efficient power plants. For residents of Corrientes and Misiones, this can mean fewer brownouts and a more reliable supply during the hot summer months when air conditioning loads spike.
Breaking Down the US$50 Million Investment
The total commitment of US$50 million covers this new Goya initiative and an earlier BESS project previously won by Aluar. That prior project, known as San Fernando BESS (adjudicated under the related AlmaGBA call), features a capacity of 30 MW.
By diversifying from aluminum smelting—an extremely energy-intensive process—into battery storage, Aluar is leveraging its deep knowledge of industrial energy management. This move allows the company to secure a direct role in grid stabilization.
The two projects together represent a meaningful pivot. Aluminum smelting requires such enormous and uninterrupted amounts of electricity that producers often build their own power plants or negotiate complex long-term supply contracts.
That experience gives Aluar an insider’s understanding of how the grid behaves under stress. By now building and operating storage assets, the company is essentially monetizing expertise it has accumulated over decades of keeping its smelters running around the clock.
Why Battery Storage Matters for Argentina
Argentina’s national grid suffers from bottlenecks and frequency deviations. Large-scale battery systems like the one planned in Goya can instantly inject or absorb power, restoring reserves at critical nodes faster than traditional thermal plants.
For expat residents and investors, a stable grid is critical for property values and industrial activity. The AlmaSADI program’s broader target of 700 MW in new storage capacity, backed by an estimated US$700 million in investment, signals a long-term federal commitment to fixing energy infrastructure.
Frequency deviations are a technical way of describing what happens when supply and demand fall out of sync on the grid. Even tiny mismatches can damage sensitive equipment or trigger automatic shutdowns.
Batteries respond in milliseconds, making them far more agile than the gas or hydro plants that have traditionally provided this balancing service. For a country looking to integrate more variable renewable sources like wind and solar in the future, having a fleet of fast-response batteries is not just helpful—it is becoming essential.
Aluar: From Factory to Energy Giant
As Argentina’s only aluminum producer, Aluar operates massive smelters that require constant, high-volume electricity. This proprietary demand makes the company uniquely qualified to manage large-scale energy assets, turning a cost center into a business opportunity.
The launch of the BESS projects marks a strategic expansion beyond commodity manufacturing. By winning public tenders designed specifically to reinforce the national system, the company positions itself as a critical partner in the government’s energy transition plan.
This evolution mirrors a global trend where heavy industrial players are stepping into grid services. Because Aluar already consumes a significant share of Argentina’s electricity for its smelting operations, it has a vested interest in a healthy, well-maintained transmission system.
The company’s move into storage can be seen as a form of vertical integration in reverse: instead of just drawing power, it now helps keep the entire system balanced, which in turn protects its own core manufacturing business from costly disruptions.
