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 1.34.1, 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. Some locations in this layer are reported by the provider as derived from OpenStreetMap (© OpenStreetMap contributors, ODbL, https://www.openstreetmap.org/copyright) and Epoch AI (CC BY 4.0).

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.

Coverage review was due 21 October 2026; no later coverage review is recorded as of 3 November 2026.

2 independently source-linked project/campus records; 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
    • No Michigan Department of Treasury or Michigan Economic Development Corporation source was opened; the only attempted path could not be retrieved.
    • No list of certified Michigan enterprise data centres was obtained, so the state's incentive recipients are entirely absent from the current research record.
    • Whether the Saline Township PA 198 industrial development district was ever established was not checked.

    Selected records

  • Utility commission and large-load records — Partly checked
    • The MPSC case system is a JavaScript application and its filing index was not enumerated; only the single filing linked by the township was retrieved.
    • Case U-21990, DTE 2025 Data Center Special Contracts, was identified but not yet reviewed directly.
    • No Consumers Energy or Michigan municipal utility large-load filing was searched, so no utility-request figure exists for any Michigan research lead outside Van Buren Township.

    Selected records

  • Environmental and construction permits — Partly checked
    • No Michigan air Permit to Install number was obtained for any data centre, so the generator fleets that are documented for Illinois have no Michigan equivalent here.
    • The EGLE site specific review for the Saline Township project is a scanned image and was not read.
    • No EGLE water withdrawal registration, wetland permit number or NPDES permit was retrieved.
    • The MiEnviro Portal was identified but not queried.

    Selected records

  • Local planning, assessor and map records — Checked
    • No county assessor or GIS parcel portal was queried in Michigan, so the only parcel identifier in the current research record is the single PA 116 parcel quoted in the Saline consent judgment.
    • No other Michigan municipality or township was visited; Lyon, Augusta, Frenchtown, Vevay, Dorr, Lowell and Gaines townships and the cities of Southfield, Lansing, Flint, Gibraltar, Dowagiac, Marshall and Ypsilanti were not reached.
    • The Saline Township site plan sheets and the consent judgment exhibits beyond page 40 were not read.

    Selected records

  • Tax abatements and development agreements — Partly checked
    • No PA 198 industrial facilities exemption certificate, PILOT or abatement instrument was retrieved for any Michigan site.
    • Whether the Saline Township industrial development district was established is unknown.
    • No state incentive agreement was reachable; see the incentives family.

    Selected records

  • Operator disclosures — Partly checked
    • No hyperscaler location page was opened for Michigan; the three Microsoft township land positions rest on the dataset alone.
    • Switch, Related Digital, Verrus, Metrobloks, Cloverleaf, Raeden and Hyperscale Data operator pages were not yet reviewed directly.
    • Google's own Michigan announcement was identified through the township page but not read, so the 2.7 GW portfolio figure it is said to contain is not carried anywhere.

    Selected records

  • Open datasets and directories — Checked
    • No unlicensed directory was used, so no cross-reference of Michigan colocation facility counts was attempted.
    • Nineteen Michigan dataset records, mostly small operating colocation facilities run by 123NET, US Signal and EdgeConneX plus the Oakland University, Prologis, Sansone, Solstice and Stantec proposals, were read only at summary level and were not turned into research leads.

    Selected records

  • Closures, withdrawals and former names — Partly checked
    • No Michigan municipal denial, withdrawal or rescission file was retrieved directly; three of the four reversals rest on the dataset alone.
    • The Deep Green Lansing status is contested between the dataset's two cited sources and no city record was obtained to settle it.
    • No closed or demolished Michigan data centre was searched for, and no rename or acquisition history was traced beyond the Hyperscale Data conversion and the former McLouth Steel site name.

    Selected records

  • News and other discovery — Partly checked
    • the current review did not include a broad discovery sweep partway through Michigan, so every Michigan source after that point had to be reached by direct URL from a document already in hand. No keyword news sweep of Michigan was possible.

    Selected records

Local evidence by place

Licensed and operator listings, reviewed records, answers and local policy for each place. Listings overlap and are not added; a place without a line here has no published local evidence.

No local evidence answer, reviewed record or local policy record is published for Allen Park, Ann Arbor, Auburn Hills, Augusta Township, Belleville, Benton Charter Township, Byron Center, Detroit, Gaines Township, Kalamazoo, Southfield, Troy. Their listings above are source listings to investigate. No statewide evidence answer is published for Michigan either; statewide rules are under Policy tracker below.

Federal and multistate instruments that cover all or part of Michigan

These federal, reliability-organization and multistate grid or utility instruments are stored once and listed for every jurisdiction they name. They do not add to the record count, in-effect total or map shading for Michigan. Territorial coverage does not establish that an instrument applies to any particular site, utility or project.
