AI data center electricity surge sweeps the globe; IREN signs 800MW transmission agreement in Australia.

```

The expansion momentum of global artificial intelligence infrastructure continues to extend into the Asia-Pacific region. AI cloud service provider IREN announced that it has signed an 800MW transmission connection agreement in South Australia, marking the company’s official expansion of its data center business into the Asia-Pacific region.

According to Bloomberg, IREN has reached a transmission connection agreement with the local power company and plans to build a large-scale data center campus in Bundey, South Australia. The campus is located about 78 miles northeast of Adelaide. Under the agreement, IREN will secure four 330kV feeder outputs at the substation, supporting a maximum electricity load of 800MW without major upgrades to the existing grid. The company expects energization of the project to start in 2028.

This project is currently one of the largest data center projects in the Asia-Pacific region and is IREN’s first data center layout announced in Australia. Analysts point out that the project’s implementation reflects that, as AI computing power demand continues to rise, enterprises are accelerating the shift of data center layouts toward emerging markets with abundant energy supply and friendly policy environments.

Green Power and Connectivity: The Dual Logic Behind IREN’s South Australia Site Selection

Amid the global wave of AI infrastructure expansion, data center site selection increasingly balances between power supply and regional network connectivity. South Australia, with its renewable energy advantage, has become a key step in IREN’s expansion in the Asia-Pacific. The state’s grid has set a target to achieve 100% net renewable energy by 2027, making it naturally attractive to AI companies seeking green computing power.

IREN co-founder and joint CEO Daniel Roberts commented: “South Australia has everything needed to support large-scale AI infrastructure: abundant clean energy, connectivity to the Asia-Pacific region, and a state government that recognizes the opportunity and is actively engaged.”

In terms of network connectivity, the Bundey campus will connect via submarine cables to core internet hubs in Singapore, Indonesia, South Korea, and Japan, providing a physical foundation for IREN to expand its regional cloud service market.

South Australia Premier Peter Malinauskas welcomed the project, saying it is “a significant investment for the state, with the potential to create hundreds of construction-phase jobs and support long-term technical employment, further cementing South Australia’s position as a center for technology and innovation in the Asia-Pacific region.”

Operationally, IREN stated it will simultaneously advance early-stage engineering and equipment procurement and accelerate the fulfillment of regulatory approvals and various preconditions under the transmission connection agreement. The project is expected to create more than 500 construction-phase jobs and over 200 long-term technical positions. The company has not yet disclosed the specific investment size, and the energization time remains set for 2028.

Intensive Financing and Capacity Expansion: Strategic Deployment Accelerates

The announcement of the Bundey project is a key part of a series of recent strategic deployments by IREN. Previously, the company completed a $3.5 billion financing arrangement to support its AI cloud service contract delivery with Microsoft. The financing consists of a $2.1 billion US private placement and a $1.55 billion delayed draw term loan, with a combined debt cost of 6.00%.

Meanwhile, IREN signed a $1.6 billion air-cooled Blackwell system procurement agreement with Dell to support a $3.4 billion managed service AI cloud contract. In terms of capacity planning, analysts at Cantor Fitzgerald estimate that IREN will add 670MW of computing power in 2027.

As a vertically integrated AI cloud service provider covering North America, Europe, and the Asia-Pacific, IREN’s revenue growth over the past twelve months has exceeded 100%. So far, the company’s market capitalization is about $23.8 billion, and its stock price has risen 652% over the past year.
