Yondr Is Building the Future of Data Centers. Here’s Why That Matters.

The AI boom needs somewhere to live. These three companies are building it right, and one of them is doing something special.

Everybody is talking about AI right now. Almost nobody is talking about where it actually runs. Every chatbot answer, every image generated, every model trained, it all lives in a building somewhere. A real building, on real land, pulling real power off a real grid, and in most cases, needing water to stay cool. That building is a data center, and the race to build them is one of the biggest infrastructure stories in the world right now.

Not every developer in this space is doing it well. Some are rushing, cutting corners, picking fights with the communities around them over water and power. But some are doing it right, building fast without losing the plan, and bringing energy and water thinking into the design instead of bolting it on later. Three of them stand out to me. One in particular deserves the spotlight.

Yondr Group: The UK Builder Making a Big American Push

Yondr Group started in London. It has spent the last several years becoming one of the more respected names in hyperscale data center development, building and operating campuses across Europe in cities like London, Frankfurt, and Amsterdam. Now it is putting real weight behind its US and Canada expansion, and the scale of that bet is worth paying attention to.

The headline move is a 163-acre site in Lancaster, Texas, just south of Dallas, where Yondr plans a hyperscale campus with capacity for 550 megawatts of critical IT load. That is a massive commitment in one of the fastest-growing data center markets on the planet. Aaron Wangenheim, Yondr’s CEO, put it simply: the US is central to Yondr’s next phase of growth, and Dallas is one of the biggest and fastest-growing markets in the world for this industry. This Dallas project is the first major announcement under his leadership, and it is a statement of intent.

Construction Moving Fast

Yondr is not just announcing projects, it is finishing them. At its Northern Virginia campus in Loudoun County, the company recently hit its first Ready for Service milestone on the second building at that site, bringing a new 12-megawatt phase online inside a 48-megawatt building, in partnership with JK Land Holdings. Todd Sauer, Yondr’s VP of Design and Construction, called it the latest in a series of achievements across the company’s North American portfolio. John Madden, Yondr’s Chief Data Center Officer, said the company is stepping up its investment in North America as demand for capacity keeps climbing. There is another 240 megawatts in the pipeline on adjacent land at that same Virginia site, which sits in the middle of Loudoun County, a region that already holds about 60 percent of the country’s primary data center inventory and more than 30 million square feet of data center space. When that build-out finishes, the campus will carry 336 megawatts on its own.

Zero Water, By Design

Here is the part that should get real attention, especially from anyone who thinks about infrastructure for a living. Yondr’s 27-megawatt Toronto facility, which broke ground in January 2025 and is tracking toward ready-for-service status in 2026, runs on a closed-loop cooling system that uses no water at all once it is operational. The building also includes bike parking, EV charging stations, bird-friendly glass, and native pollinator plantings, and it was designed to meet Toronto’s Green Standard while supporting Yondr’s company-wide goal of net-zero emissions by 2030. This is a company building water thinking into the blueprint instead of trying to fix it after the fact.

More Than a Neighbor

Yondr also partnered with the University of Toronto to fund a scholarship program, five years of annual $5,000 awards for students studying computer science, commerce, life sciences, and math, starting in fall 2025. That is a company thinking past the ribbon cutting and investing in the people who will grow up next to its buildings. Between the construction pace, the zero-water design, and the community investment, Yondr is putting together one of the more complete growth stories in this industry right now, and it is only getting started in North America.

QTS: Going Big in Virginia, and Bigger on Water

QTS has quietly become one of the largest data center operators in the country, and its home base in Henrico County, Virginia, shows exactly how far it is willing to go. The company is moving forward on two new campuses there, RIC4 and RIC5, adding roughly 1,100 acres to a footprint that already anchors one of the most important data center hubs in America. Between the two sites, QTS has put over $160 million into land alone, with plans for as many as 17 new buildings and total campus space pushing toward 8 million square feet. Henrico already pulls in millions of dollars a year in real estate tax revenue from the data centers standing there, and this expansion builds on that base.

The Water Commitment

This is the part worth slowing down for. QTS says it flatly: zero water for operational cooling, because water has better things to do. Its closed-loop cooling design avoided billions of gallons of water in 2025 alone compared to facilities still running old-school evaporative cooling. On top of that, QTS hit 100 percent carbon-free electricity across its operational facilities in both 2024 and 2025, and it ranks as a Top 50 EPA Green Power user. The company backs this up with a $1 billion global water stewardship pledge aimed at water-positive operations by 2035, and a dedicated $250 million commitment specifically for Texas water infrastructure over the next ten years. It also runs a tree development replacement program built to plant more trees than it clears. That is a company treating water like the resource it actually is, not an afterthought.

Digital Realty: Renewable by Design in Zurich

Digital Realty is one of the biggest names in this business worldwide, and its latest move in Switzerland is a good example of what smart, sustainable scale looks like. The company broke ground in August on ZUR4, a new 15-megawatt facility in Glattbrugg that expands its existing Zurich campus. The build adds to a European portfolio that already runs entirely on renewable energy, and its existing ZUR2 facility holds the first-ever Platinum Plus certification from the Swiss Datacenter Efficiency Association.

Yves Zischek, Digital Realty’s Managing Director for the region, said the investment reflects both the strategic importance of the market and the growing demand for AI-optimized, sustainable digital infrastructure. Local officials echoed that, pointing to the jobs and innovation capacity these projects secure. ZUR4 is set to be complete in 2028, and it is one more sign that the biggest players in this industry are building for the long term, not just the next earnings call.

SUPER COOL

The AI boom is not slowing down, and the companies building the physical infrastructure behind it are going to shape how this next decade looks, for better or worse. Yondr, QTS, and Digital Realty are three very different companies, a fast-growing UK challenger, a Virginia-rooted giant, and a global REIT, and all three are showing you can build at massive scale without losing sight of the community and the water and grid you are building into.

That is worth watching. That is worth rooting for. Keep building.
