Iren Plans 800MW Australia AI Data Center Campus as Power Becomes the Capacity Gate
Iren signed a transmission connection agreement for a planned 800MW data center campus in Bundey, South Australia. The project is Iren's first Australian foray and is expected to be energized in 2028 as the company shifts more cash flow toward AI cloud infrastructure. The practical test is whether Iren can turn grid-connected power, financing and GPU capacity into energized AI cloud campuses on the announced timelines.
Iren Moves Its AI Campus Pipeline Into Australia
Iren is extending its AI infrastructure build-out into Australia after signing a transmission connection agreement for a planned 800MW data center campus in Bundey, South Australia.
The US data center and cloud firm said the project is its first Australian foray, with the site expected to be energized in 2028.
The announcement turns South Australia into the next test site for Iren's shift from crypto mining toward AI cloud infrastructure.
Iren is still mining Bitcoin, but it is winding down mining operations and redirecting cash flow toward its AI business.
Daniel Roberts, Iren's co-founder and co-CEO, framed the location around power and regional reach.
Roberts said South Australia offers clean energy, APAC connectivity and a state government that understands the opportunity.
He added that the Bundey campus could serve global and regional AI demand as well as South Australia's own AI compute needs.
Power Access Becomes the Commercial Gate
The transmission connection agreement is the concrete step in the announcement because power access is a gating issue for large AI campuses.
Full project details have not been shared.
Bundey is in South Australia's Mid North region, roughly 125km from Adelaide.
South Australia's premier, Peter Malinauskas, said the proposed campus could create hundreds of construction jobs, support long-term skilled roles and strengthen the state's technology position in the Asia-Pacific region.
The scale of the plan also fits Iren's broader expansion pipeline.
The company says its data center pipeline has reached 5GW across sites in Texas, Oklahoma and British Columbia, alongside the new Australian plan.
It also claims about 23,000 GPUs in its fleet and said in October that contracts had been secured for around 11,000 of them.
AI Cloud Expansion Still Needs Execution Proof
Iren's recent moves point to a faster pivot into AI cloud infrastructure.
The company acquired Spanish data center firm Nostrum, adding secured grid-connected power in Spain of about 490MW.
Nvidia is set to invest up to $2.1 billion in Iren for compute deployment of up to 5GW, while Iren also closed a $3.65bn investment-grade GPU financing facility tied to its AI cloud contract with Microsoft.
The practical test is whether Iren can turn grid-connected power, financing and GPU capacity into energized AI cloud campuses on the announced timelines.
For buyers of AI compute, the Bundey signal is that power-secured regional campuses are becoming part of the capacity race, not only conventional cloud regions.
