STACK Infrastructure’s $6B Green Investment Milestone Drives Sustainable Data Center Growth

2025 Data Center Project Announcements

STACK’s 2025 development roadmap reflects a deliberate expansion strategy focused on both scale and market adjacency. With a suite of new and ongoing projects spanning North America and the Asia-Pacific corridor, the company is deepening its footprint in hyperscale hubs while establishing competitive positions in high-growth international markets.

Major announcements have included:

• A flagship data center development, the 1+GW Stafford Technology Campus (STC) in Stafford County, Virginia. The 500 acre development in NoVa represents 19 data centers, four sub-campuses, six 300 MW substations and a significant economic investment in the county.
• A 220 MW data center campus in Johor Bahru’s Iskandar Puteri in Malaysia, expanding the company’s presence in the largest market in the region
• Expansion of STACK’s Loudoun County, VA footprint with a 144 MW hyperscale data center campus, located in the greater Ashburn data center cluster.
• A 36 MW data center campus in Elk Grove Village (Chicago) Located in proximity to the company’s existing Chicago data center the facility will have a local ConEd substation to deliver the 36 MW critical capacity to the two story, 263,000 sq ft building.

Other existing, in-process development projects include:

• A 500 MW south Dallas campus, spanning 100 acres, strategically engineered to accommodate both shell and turnkey deployments.
• A 56 MW Toronto campus, spanning 19 acres, includes an existing 8 MW data center and 48 MW expansion capacity, all supported by committed power.
• A 250 MW campus in Central Phoenix with a dedicated on-site substation.
• A 200 MW campus in Portland spanning 55 acres with 24 MW of available capacity and 96 MW of future expansion.
• A 48 MW build-to-suit opportunity in the Dallas/Fort Worth area, offering significant power and connectivity options.

These developments show that the North American market will be the primary focus of STACK’s efforts, especially after the sale of the company’s European colocation business, and its seven data centers, to Apollo Global Management’s infrastructure portfolio, that we had previously reported on.

APAC Focus

STACK is, however, continuing to put significant focus on the rapidly eveloving APAC data center market, looking for approximately AU$1.3 billion (US$833 million) in financing to expand its data center footprint in Australia. Over AU$500 million of funding is tagged as green funding to support sustainable development initiatives.

The region is seeing a significant growth in demand for data center services to support cloud computing and AI service delivery. Expansion plans include developing a 180 MW campus in Melbourne, which is part of a broader strategy to establish a significant presence in Australia’s major data center markets. This includes existing operations in Canberra and Melbourne, with the Melbourne campus featuring two 36 MW facilities, and the Canberra site offering 28 MW of IT capacity.

The funding and development will give STACK better positioning in competing with Blackstone, the largest of the alternative asset management companies, who most recently spent AU$24 billion to acquire hyperscale data center operator AirTrunk at the end of 2024. Data center competition in Australia also includes NextDC, a rapidly growing, homegrown company.
