Opposition and litigation at this site

Nothing on record as of September 12, 2026. No lawsuit, organized opposition, or contested hearing over Microsoft Hoffman Estates Data Center in Hoffman Estates, Cook County, Illinois 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.

Notes on the record

53-acre campus on the north side of Lakewood Boulevard near Barrington Road, approved by the Hoffman Estates Village Board in May 2021. Distinct from Microsoft's Elk Grove Village and Northlake sites. Investment figure is the capital-investment commitment recorded in the state MOU; a trade-press account attributes a higher figure to the campus, so the state number is used here as the documented commitment.

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
  • 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.
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.

Distances are between recorded coordinates, many of which are a city or county centroid, so treat them as approximate. Cumulative load on one utility and one aquifer is the question a planning commission rarely asks.
