What are the main site selection criteria for a data center?

In 2026 the criteria are ranked, not equal. Power comes first — how many megawatts are available and, just as important, when they can be delivered through the utility interconnection queue. After a site clears the power test, developers weigh acreage and configuration (room to build in phases), fiber connectivity, water and cooling strategy, topography and flood risk, environmental condition, zoning and community sentiment, and incentives. Grid readiness has overtaken land readiness as the gating factor: a network-rich, well-shaped parcel with no committed power is not a viable data center site, while an ordinary parcel with firm megawatts is.

How many acres does a data center need?

It depends on scale. A single building can sit on roughly 10 acres, but modern hyperscale campuses are built to grow — often needing room for well over a million square feet and 300-plus megawatts, which pushes site requirements into the hundreds and sometimes a thousand-plus acres. The flagship Stargate campus outside Abilene, Texas spans about 1,100 acres. Developers value contiguous, well-shaped, expandable land far more than a tight lot that caps future phases.

Why is power the most important data center site criterion?

Because power is now the scarce input. ERCOT's large-load interconnection queue grew from about 63 GW in December 2024 to roughly 410 GW by March 2026, with the large majority tied to AI data centers — far more than the grid can serve quickly. That scarcity means a site's value tracks its committed, verified power capacity and interconnection timeline more than any other factor. Land is abundant; deliverable megawatts are not.

Data center site selection criteria: the 2026 Texas checklist

Data center site selection in 2026 is decided in a fixed order: power first, then everything else. A site has to clear a power test — enough megawatts, deliverable on a workable interconnection timeline — before acreage, fiber, water, topography, flood risk, and zoning even matter. Grid readiness has overtaken land readiness as the gating factor, and nowhere is that clearer than in Texas, where ERCOT’s large-load queue ballooned from about 63 GW in December 2024 to roughly 410 GW by March 2026, the large majority tied to AI data centers. The practical takeaway for a landowner: your parcel’s power position, not its price per acre, sets whether it’s a data center site at all.

The criteria, in the order developers actually apply them

Every credible site-selection process screens on power first and eliminates most parcels immediately, then ranks the survivors on the rest. Here is the working checklist.

1. Power capacity and interconnection timeline

The first question is how many megawatts a site can get and when. A mid-size project needs tens of megawatts; a hyperscale campus needs 300 MW and up. What matters is committed, verified capacity from the utility — not a requested number in a queue. In Texas that means proximity to high-voltage transmission (345 kV lines and substations) and a realistic interconnection path under ERCOT’s new large-load rules. We cover this in depth in powered land and ERCOT interconnection.

2. Acreage and configuration

A single building can fit on roughly 10 acres, but modern campuses are built to expand — often needing room for well over a million square feet and 300-plus megawatts, which pushes requirements into the hundreds or over a thousand acres (the Stargate campus outside Abilene spans about 1,100 acres). Developers pay up for contiguous, well-shaped, expandable land and discount tight or oddly configured lots that cap future phases.

3. Fiber and latency

Fiber is important but, in 2026, treated as solvable if the harder constraints are met. A site with strong power positioning but thin network presence is still viable; a fiber-rich site with no power is not. Long-haul routes and distance to major Texas interconnection points shape latency-sensitive uses.

4. Water and cooling strategy

Cooling drives water demand, and the industry now resolves water strategy early rather than treating it as a downstream engineering problem. Closed-loop and air-cooled designs have changed the math, but a site’s water sourcing and permitting still make or break large campuses — see data center water, cooling, and permitting.

5. Land quality: topography, flood, environmental

Flat, dry, clear, geotechnically sound dirt builds cheaper. FEMA floodplain, steep grade, wetlands, and contamination all subtract usable area and add cost. In the Hill Country, add Edwards Aquifer water-quality rules and impervious-cover limits to the diligence list.

6. Zoning, permitting, and community sentiment

Since mid-2025, Texas localities have weighed 100-plus data center ordinances — moratoriums, buffers, and permitting frameworks — and in August 2026 the state ordered a grid-connection audit that slowed new projects. Jurisdiction and local posture now carry real weight in ranking sites.

7. Incentives, labor, and access

Tax abatements and economic-development agreements, construction and operations labor, and highway access round out the scorecard once a site has cleared power, land, water, and permitting.

Why “powered land” commands a premium

When power is the scarce input, land that already carries committed capacity is worth a multiple of raw acreage. In one 2026 Texas transaction, a developer paid up to $76.5 million for 66 acres near Graham — roughly $1.16 million per acre — where comparable rural land ran under $2,000 per acre. The real asset wasn’t the dirt; it was 164 MW of secured interconnection. Committed utility load has become the single strongest predictor of data center land pricing.

How SCORE screens a site

Steven Owen evaluates a parcel the way a data center developer will — an engineer with an NYU Stern finance MBA who starts with the power position and the ERCOT interconnection path, then layers in acreage, water, flood, jurisdiction, and incentives before quoting a number. SCORE assesses where your land sits against transmission and substations, what the realistic megawatt and timeline story is, and which developers are actively buying, then takes it to them through a direct developer and investor network.
