- Under construction · 0News reporting construction underway at the site.
- Planned · 0A TCEQ air permit on file with no mapped building yet, or a project announced in the news. Permits come before buildings, so this is the early-warning state.
- Paused · 0News reporting the project on hold.
- Inactive · 0News reporting the facility closed or the project cancelled.
- Registered, status unknown · 0In a state registry under a program that says nothing about construction (no air permit, no mapped building). Unknown is the answer, not a guess.

How this registry is counted
One row is one campus. OpenStreetMap maps individual buildings, so buildings within 400 meters of each other fold into a single facility; a facility found by two sources within 400 meters of each other is one row that lists both. Coordinates are never altered — a merged row keeps the mapped building’s position.
Status is inferred from what each source states and nothing more: a mapped building or a Texas Comptroller registration means the facility exists; a TCEQ air permit with no building yet means it is permitted, not built; a registry entry under a non-air program says nothing about construction, and the row says so. No source here confirms anything on site.
State and county come from the U.S. Census TIGER/Line county boundaries the facility point falls inside. Every count on this page is computed from the same registry file — nothing is typed in by hand.
Questions
How many data centers are in Marathon County, Wisconsin?
As of the September 18, 2026 registry snapshot, Marathon County has 1 facility: 1 operational. Named facilities include Switch AUS 4. Only facilities recorded by a public source Geolocity mirrors are counted.
Where do these rows come from?
Buildings tagged as data centers in OpenStreetMap, the Texas Comptroller's data-center program registry, and facilities registered as data centers in TCEQ's Central Registry. Each row links the record it came from. County placement uses U.S. Census TIGER/Line boundaries.
What does a data center near a parcel mean for the land?
Two things a landowner cannot see from the surface: demand for nearby land and competition for local water and power. The Geolocity parcel report shows every facility within 25 miles of a specific address alongside the aquifer beneath it and the county's industrial water use. This page is the public record; it is information, not advice.
