Argentina's Patagonia Attracts Massive AI Data Centers Amid US Power Constraints

OpenAI’s planned Patagonian facility is expected to begin with a 100-megawatt phase in 2027 and represents Latin America’s entry into the Stargate infrastructure program, which also includes projects in Norway, the United Kingdom and the United Arab Emirates.
Other proposed projects include FlexDomes’ 120-megawatt first phase, estimated to cost $1.4 billion, and Green Capital’s planned 300-megawatt facility in Chubut, which could eventually expand to 3,000 megawatts. Green Capital is leasing about 1,300 square kilometres south of Trelew for wind and solar generation.
Pampa EnergÃa’s proposed 500-megawatt Neuquén facility would require roughly $900 million in infrastructure investment, while its separate BahÃa Blanca project is expected to start with a 30-megawatt phase.
Argentina’s RIGI investment regime offers qualifying projects 30 years of stability covering taxes, customs and foreign-exchange rules, a provision intended to provide greater certainty for large, long-term data-center investments.
Local and international companies reportedly linked to the potential buildout include Genneia and Vista Energy on the energy side, while Amazon and Alphabet were named among the technology companies evaluating opportunities.
Argentina's Patagonia is emerging as a major hub for artificial intelligence data centers. Tech companies and investors are fleeing power-starved regions in the United States and Europe, drawn to Patagonia's cool climate, abundant wind and hydroelectric power, and tax incentives that offer 30 years of investment stability Dainik Jagran.
OpenAI is planning a facility that could reach 500 megawatts and cost $25 billion. Other projects include FlexDomes' $1.4 billion center and Green Capital's 300-megawatt facility that could eventually expand to 3,000 megawatts Cryptopolitan. The rush reflects a global competition for AI infrastructure as demand for computing power accelerates.
American data-center projects are running into fierce local resistance. Communities worry about electricity demand straining grids, environmental damage, and rising utility costs for residents BigGo Finance. Tech companies have hit roadblocks securing permits and community approval for large facilities.
This pushback has forced developers to look overseas. Patagonia offers a way to escape these constraints while still building the infrastructure needed for AI workloads that are growing rapidly worldwide Energy Now.
The region has three powerful draws. First, its cold climate means data centers need less cooling—a major cost. Second, Patagonia produces abundant renewable energy from wind and hydroelectric sources. Third, the Vaca Muerta shale formation provides natural gas for backup power Dainik Jagran.
Argentina's RIGI investment regime sweetens the deal. It guarantees 30 years of stable tax, customs, and foreign-exchange rules Tech Republic. This long-term certainty is rare and helps companies justify billion-dollar commitments.
OpenAI's Sur Energy project is the headline act. It will start with a 100-megawatt phase launching in 2027, then potentially reach 500 megawatts and $25 billion in total investment Cryptopolitan. This marks Latin America's entry into Stargate, a global AI infrastructure program.
FlexDomes is building a 120-megawatt first phase for $1.4 billion. Pampa EnergÃa proposed a 500-megawatt site near Neuquén requiring $900 million in infrastructure spending Tech Republic. Green Capital is leasing 1,300 square kilometers south of Trelew for wind and solar farms to power its 300-megawatt facility BigGo Finance.
Despite the momentum, these projects face real hurdles. Developers must secure financing, build reliable power infrastructure, and install high-capacity fiber connections Energy Now. Many plans remain preliminary and depend on Argentina's future economic and political stability.
Industry analysts caution that the RIGI tax incentives could change if Argentina's government shifts. Amazon and Alphabet are reportedly evaluating opportunities, but no firm commitments have been announced BigGo Finance. Success depends on whether Argentina can deliver on its promises to foreign investors.
