Opposition and litigation at this site

Nothing on record as of September 10, 2026. No lawsuit, organized opposition, or contested hearing over CloudHQ Mount Prospect (ORD) Campus in Mount Prospect, 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

$2.5B, ~1.5 million sq ft across three two-story hyperscale buildings (each >80 MW) on a 49.7-acre site; ComEd grid partnership. Update: the village board approved a revised plan (~Oct 2025) consolidating the original three two-story buildings into two three-story buildings plus a second electrical substation, superseding the building-count description above; confirmed delivery targets are the first building in 2027 and the second by end of 2030. As of July 2026, CloudHQ was mid-permitting the revised design (~3,700 drawing sheets, 1,500+ pages of structural calcs); the village hired outside firm HR Green to review it. Construction is active, with cranes on the fenced 50-acre site as of January 2026. Public-reception check (2026-09-10): Could not get past a paywall/block for the Daily Herald's Mount Prospect coverage or the original CloudHQ groundbreaking press release (both 403'd). Notable circumstantial signal: the Village of Mount Prospect maintains its own dedicated 'Community Information and Fact Check Portal' page specifically for this project (URL found via search, itself 403'd on fetch), which typically indicates the village has been fielding enough resident questions/concerns to warrant an official FAQ/rebuttal page -- but I could not retrieve its actual content, so I am not asserting a status from an inference I couldn't verify. Also found (via search, not independently fetched) reporting that Illinois data-center opposition broadly 'escalates' statewide and that the village sought outside help on Biometric Information Privacy Act (BIPA)-related permitting questions, neither of which I could confirm as specific to community opposition at this site. Reporting 'unknown' rather than guessing.

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
  • How the community has received 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.
How the community has received it
Planning commission and governing body minutes, public comment records, and any petition or lawsuit filed in the county.

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.
