Notes on the record

440-acre proposal off Highway 370 in the City of St. Charles. CRG President Christopher McKee's letter said the developer would retool the proposal, but the city moved to a moratorium and then (May 2026) an outright data center development ban, so it is recorded as cancelled. The end user was undisclosed; a later headline reported documents linking it to Google, which was not independently verified here and so is not recorded. Coordinates are the St. Charles city centroid, not the parcel.

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
  • 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.
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.
