Opposition and litigation at this site

Nothing on record as of September 14, 2026. No lawsuit, organized opposition, or contested hearing over Otava Ann Arbor Data Center in Ann Arbor, Washtenaw County, Michigan appears in the sources this registry tracks. That is an absence in our sources rather than a finding that none exists, and local opposition often predates any coverage a national dataset would pick up.

If you live near this site and something is happening that this page does not show, that is worth telling us. Send us the document and it goes in the record with the source attached. For sites where opposition is already established, see every contested site we track.

A new status, a permit, a reception finding, or a lawsuit. Nothing else, ever.

Notes on the record

DELIBERATE GAP: the operator page places this facility in the Avis Farms business park south of downtown but does not print a street address, and the commonly-cited 640 Avis Dr address appeared only in a search-results summary this session, never on a page that was fetched, so no street is asserted and the pin is a city-level geocode, not the building. A maintainer adding the address should confirm it against an operator-published page first. Generator/UPS figures are in kVA as published; no MW is derived from them.

What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Power capacity in megawatts
  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
  • Land area
  • How the community has received it
  • Which utility serves it
Which document closes each gap
Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
Cooling method and water use
The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.
Land area
The rezoning application, the plat, or the deed recorded with the county.
How the community has received it
Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.
Which utility serves it
The electric service agreement or the utility's filing with the state public utility commission.
