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 14 September 2026. Individual records and claims below show their own evidence dates and may be newer.

Next scheduled review: 13 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.

Source families checked, selected records and remaining gaps

These notes name selected records, say which kinds of public evidence were checked and show what remains missing. They do not add anything to the published counts.

  • economic development incentives — Partly checked
    • Montana Code Annotated property-class provisions for data centers were not retrieved.
    • No state incentive award or certification list was located.
    • the current review did not include a broad discovery sweep for this state, so discovery relied on direct review of known official URLs.

    Selected records

  • utility commission large load — Partly checked
    • The Montana PSC docket system was unreachable in the current review (connection error), so no large-load tariff, special contract or docket number was verified.
    • NorthWestern's Rates & Tariffs and SEC filings pages were not yet reviewed directly.
    • No interconnection queue record was retrieved for the 1,100 MW Big Sky request.

    Selected records

  • environmental construction permits — Partly checked
    • DEQ's issued-permit database was not located; one programs path could not be retrieved and another path was unavailable.
    • No air, water or stormwater permit was found for the Big Sky, Sabey or TAC sites.
    • Montana DEQ permit numbers for other bitcoin mining sites were not swept.

    Selected records

  • municipal planning assessor gis — Partly checked
    • City of Great Falls and Billings City-County Planning records remain incomplete; later Butte-Silver Bow records were opened for an unverified lead only.
    • No assessor or GIS parcel record was retrieved in Montana.
    • Yellowstone County zoning commission minutes for the Broadview-area site were not obtained.

    Selected records

  • tax abatement development agreements — Partly checked
    • The image-only proposed agreement is excluded from the queued claim because it was not independently re-read; its exact acreage, parcels and signatures remain unverified, as do authorization, execution, any amendment, closing, current contract performance and tax-abatement terms.
    • The Great Falls Development Alliance materials behind the TAC land-lease option were not obtained.
    • No Basin Creek TEDD agreement was retrieved for the separate Atlas Power lead.

    Selected records

  • operator disclosures — Checked
    • Amazon Web Services, Microsoft, Oracle and Apple location pages were not checked for Montana.
    • Sabey Data Centers' and TAC Data Centers' own sites were not yet reviewed directly.
    • Beowulf Electricity and Data's site was not yet reviewed directly.

    Selected records

  • open datasets directories — Checked
    • Data Center Map could not be retrieved during review to the available access methods, so no directory cross-check of Montana colocation facilities was possible.
    • Baxtel and similar listings were not used.

    Selected records

  • historical closures withdrawals names — Partly checked
    • No city, county or state record confirming the TAC withdrawal was obtainable.
    • Whether the Hardin decommissioning is permanent is unresolved; the operator says it intends to expand.
    • No archived-page sweep was performed for renamed Montana facilities.

    Selected records

  • news and other discovery — Partly checked
    • Data Center Dynamics could not be retrieved during review to retrieval, so the 1 GW campus report was not read.
    • The MEIC hub page's per-project sub-pages were not enumerable from the saved HTML.
    • Legislative Energy and Technology Interim Committee minutes, referenced in the news, were not retrieved.
