Opposition and litigation at this site
Nothing on record as of September 14, 2026. No lawsuit, organized opposition, or contested hearing over K.I. Sawyer Data Center (SAGE building / Greenfield Campus) in K. I. Sawyer, Marquette 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.
Power and water
Backers describe building an on-site natural gas generator only once an end user is signed; construction of the generator "could take up to two years." No generation capacity or permit has been published.
Notes on the record
Marketing-stage only: no permit, no township application, no end user. Capacity tiers advertised by the promoters (25 MW / 50 MW / 500-1,000 MW, phased) are sales material, not committed capacity, and are deliberately NOT recorded in capacityMw. Press places the site in Forsyth Township; the OSM geocode for the K.I. Sawyer place resolves inside Sands Township, the former base straddles both, so only the county is asserted here.
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.
