OpenAI's initiative with Sur Energy would be one of Argentina's largest energy infrastructure projects ever, with 500 megawatts of capacity.

OpenAI and Sur Energy have signed a letter of intent for a data center project in Argentina requiring an investment of up to $25 billion, the South American nation's government said on Friday.

Investing.com -- Central Puerto SA (NYSE:CEPU) stock jumped 6.8% in after-hours trading Tuesday following a report from Bloomberg saying that the Argentinian power producer signed a memorandum of understanding to potentially supply renewable energy to a proposed $25 billion data center project in Argentina.

OpenAI, Oracle and SoftBank announced five new AI data center sites for the $500 billion Stargate project, bringing the total allocated investment to over $400 billion.

The companies said OpenAI would design the chips, which Broadcom will develop and deploy starting in the second half of 2026. They will roll out 10 gigawatts worth of custom chips, whose power consumption is roughly equivalent to the needs of more than 8 million U.S. households or five times the electricity produced by the Hoover Dam.

The ChatGPT maker is teaming with Oracle and SoftBank on the facilities, at an expected cost of more than $300 billion.
