Overview

• The letter of intent was presented to President Javier Milei as the companies pursue Argentina’s RIGI incentive regime for large investments.
• The multi-stage facility is planned for Patagonia and would run primarily on renewable energy, with final site selection expected in the coming months.
• Construction is targeted to start in 2026, with an initial phase of roughly 100 MW online by late 2027 before scaling toward the 500 MW goal.
• Sur Energy will develop and finance the project via a joint venture with an unnamed top-tier cloud infrastructure partner, while OpenAI acts as the offtaker rather than the main builder.
• OpenAI frames the project as part of its global Stargate initiative and cites Argentina’s strong AI adoption and talent base as reasons for the selection.
