IREN builds 2GW AI data center

AI infrastructure is turning into a power story. Not a software story, not even really a chips story first — a power story. That’s why IREN’s upd(markets.businessinsider.com)2GW Sweetwater campus from plan to live electrical reality. (markets.businessinsider.com)6096715)) ### What actually happened at Sweetwater? “Energization” sounds boring, but it’s one of the few milestones that tells you a data center project(openai.com) with construction and commissioning, instead of living as a rendering and a land option. For IREN, Sweetwater 1 is the first big electrical block inside a broader 2,000MW campus in Texas.

Sweetwater’s first energized site alone is measured in gigawatts, and the full campus is planned for 2GW across more than 1,800 acres. IREN says that footprint could support more than 700,000 liquid-cooled Blackwell GPUs. (iren.com) ### Why Texas? Basically — power, land, and grid structure. West Texas gives developers room to build huge campuses, and ERCOT makes it poss(markets.businessinsider.com)n deliver power at the fence, on time, with transmission and cooling solved” are very different things. Energization matters because it narrows that gap. (markets.businessinsider.com) ### Is this just an IREN story? No. It fits a much bigger land grab for AI capacity. OpenAI said on April 29 th(iren.com)S. infrastructure target set for 2029, with more than 3GW added in the prior 90 days alone. Whether every announced watt turns into operating compute on schedule is another question, but the direction is obvious — the industry is now planning in gigawatts. (openai.com) ### Why does storage keep showing up in this conversation? Because compute needs (markets.businessinsider.com)d an initial €50 million Series C round at a valuation above €1 billion, pitching long-duration, non-lithium storage as a way to give data centers and utilities multi-hour dependable capacity. In plain English — if AI campuses are the load, storage is becoming part of the survival kit. (cmblu.com)ner with extra land. IREN has been repositioning as an AI infrastructure company with AI cloud, colocation, and build-to-suit capacity. Its November 2025 Microsoft deal — valued by IREN at about $9.7 billion — centered on delivering GPU cloud infrastructure from its Texas campuses, including 200MW of critical IT load in Childress. Sweetwater pushes that strategy further up the scale ladder. (iren.com)ll at once. The analogy is simple: the AI boom used to look like a race to buy servers. Now it looks more like a race to build small industrial cities around those servers. (openai.com) ### Bottom line? IREN didn’t just announce another AI project. It cleared a milestone that says gigawatt-scale AI campuses are moving from speculative capital markets language(iren.com)els — they’re the ones that can actually get power to the rack.
