Map sources and method
The state outline is adapted from the U.S. Census Bureau 2025 cartographic boundary file. Facility coordinates are adapted from Compute Atlas by Edward Kubiak, edition 1.33.0, under CC BY 4.0. Outline and markers use one geographic projection before any explicitly disclosed readability offset. Exact singleton source anchors are never moved. A one-kilometre boundary tolerance prevents the simplified 1:20,000,000 outline from hiding legitimate border-area source points; farther conflicts are disclosed, not clamped. DataCenterData groups source-reported city coordinates only within a bounded map radius; the outline does not validate a facility record.

Where the records were checked
Statewide audit pending
A few checked sites
This is not a list of every data center in the state, and the number here is not a count of them. There are almost certainly more.
Statewide coverage is not complete. The records below are sourced; a full statewide count has not been published.
State research audit window ended 12 September 2026. Individual records and claims below show their own evidence dates and may be newer.
Next scheduled review: 12 March 2027.
1 independently source-linked project/campus record; 0 independently source-linked facility/building records; 0 attributed or unresolved rows. These counts use different units and must not be added together.
