Argentina is promoting an artificial intelligence data center in Patagonia as a major investment, but public plans differ on its eventual size and the project remains at an early stage.
The proposed Atlas GigaHub is planned for Chubut. Argentina’s investment agency said in a July announcement that Green Capital’s project was undergoing initial environmental studies and legal and financial structuring. The agency described plans for 3,000 megawatts of capacity based on wind and solar power, with $30 billion in investment over the long term.
President Javier Milei said in an Oct. 15 speech that his government would not regulate artificial intelligence preemptively. The Casa Rosada transcript also describes plans for limited liability for companies using AI agents and tax benefits.
A separate proposal, known as Super RIGI, would set a 15% income-tax rate for qualifying projects with at least $1 billion in investment. It would also require companies to commit to investing at least 20% of that minimum within two years of joining the regime. The Chamber of Deputies passed the bill 130-106, with seven abstentions, on June 24 and sent it to the Senate. The government named the existing Large Investment Incentive Regime (RIGI) for Atlas. Whether the project could qualify for Super RIGI has not been established.
Green Capital’s current website describes a 6-gigawatt computing platform in Patagonia. Reuters reported that the company planned to begin with a 300-megawatt, $3 billion phase, with possible capacity later reaching 3,000 megawatts. The government’s 3,000-megawatt projection and the company’s 6-gigawatt figure have not been reconciled. The government’s $30 billion long-term estimate and Reuters’ $3 billion initial-phase figure also remain unreconciled.
The Associated Press reported that Green Capital had not secured a customer, permits were pending and construction was not expected to start until around 2028. AP also reported that the company had not detailed water needs or what share of its electricity would come from gas. AP calculated that a year of operation at projected peak demand would require roughly 2.7 times the electricity Buenos Aires used in 2025.
Chubut officials told AP they expect the project to attract investment, create skilled jobs and provide a market for surplus wind power. Some nearby residents have raised concerns about water use. Cristina Gibón told AP, “There’s just so little information.” The Super RIGI bill awaits Senate action, with no vote date reported.
