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).

Separate layer

Also listed by operators

Sites that operators list on their own websites and that are not rows in the licensed directory above. They are kept apart and never added to the licensed rows.

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 coverage review: 13 March 2027.

0 independently source-linked project/campus records; 1 independently source-linked facility/building record; 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 Pine Tree Development Zone certification list or TIF district register was opened.
    • Maine Revenue Services sales and use tax exemption material was not consulted.
    • the current review did not include a broad discovery sweep for this state, so the incentive audit was limited to pages reachable by exact URL.

    Selected records

  • Utility commission and large-load records — Partly checked
    • The open-case grid was not paged beyond the first 20 records.
    • No case-title or full-text search of Maine PUC cases was actually executed.
    • No Versant Power or Central Maine Power large-load tariff, ESA or interconnection record was consulted, and ISO New England queue material was not checked.

    Selected records

  • Environmental and construction permits — Partly checked
    • No Maine DEP air, site location, stormwater or natural resources permit was opened for any of the three leads.
    • The Compute Atlas note that no permits were issued for the Jay project was not verified against a DEP or town permit record.
    • Municipal building and site plan permits were not reachable for Jay, Wiscasset or Limestone.

    Selected records

  • Local planning, assessor and map records — Checked
    • The Maine statewide parcel layer has no owner or assessor attributes, so no Maine research lead could be tied to a parcel.
    • Wiscasset and Limestone town sites could not be searched (JavaScript widget and no index respectively); no planning board or selectboard minute was read for any Maine site.
    • Jay select board agendas and minutes archives were not paged back to the 2025 warrant that reportedly backed the data center plan.

    Selected records

  • Tax abatements and development agreements — Partly checked
    • The 2025 Jay town meeting warrant that reportedly backed the data center plan was not located; only the current warrant page is published.
    • No Wiscasset option agreement, ARPA award document or Lincoln County commissioners' record was read.
    • The executed Eternal Mind lease, its commencement and expiration dates, amendments and current performance were not available.

    Selected records

  • Operator disclosures — Partly checked
    • LiquidCool Solutions', Green 4 Maine's and Sentinel Data Centers' own websites were not yet reviewed directly; no exact source retrieved here establishes their current roles.
    • No current Eternal Mind occupancy, operation, lease-performance or termination record was found.
    • Amazon Web Services, Microsoft, Google, Meta, Oracle and Apple were not checked for Maine sites; none appears in any source opened here.
    • No colocation operator with a Maine presence was identified.

    Selected records

  • Open datasets and directories — Checked
    • Directory listings (Data Center Map, Baxtel, datacenters.com, PeeringDB) were not consulted for Maine.
    • No cross-check was made against other trackers.

    Selected records

  • Closures, withdrawals and former names — Partly checked
    • No LD number, bill text, committee report or veto message was retrieved for the reported Maine data center moratorium.
    • The Jay cancellation is evidenced only by the licensed dataset; no town or company document confirming it was read.
    • No archived or historical sweep was made for older Maine data centers.

    Selected records

  • News and other discovery — Not checked
    • The Bangor Daily News, Maine Monitor, Central Maine, Maine Morning Star, News Center Maine and Site Selection articles the licensed dataset cites were not retrieved.

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 Brunswick, Jay, Lewiston, Millinocket, Portland, Sanford, Wiscasset. Their listings above are source listings to investigate. No statewide evidence answer is published for Maine either; statewide rules are under Policy tracker below.

Review dates: the 5 Maine records were last checked 22 September 2026 to 23 September 2026. 3 scheduled reviews are overdue as of the tracker date 3 November 2026: Data centers excluded from business equipment exemption and Dirigo incentives, Data Center Advisory Council and ratepayer protection order (last checked 23 September 2026, review due 23 October 2026); Brewer: tiered data center standards; 20 MW and over prohibited (last checked 22 September 2026, review due 22 October 2026). Overdue means not re-read yet, not changed. No single record, and not this list, establishes complete statewide policy coverage.
