Illinois data center construction tracker

What these public records establish

Use the actual city, village or county behind a record. Chicago market context does not identify the governing authority or permission for every Illinois site.

31 published public records on this page; 30 include the current field-level source report. Other previews retain their narrower published scope. These counts are records in Radar, not unique campuses, statewide totals or active bids.

Use the recorded-stage filters to choose a lead, then match a dated decision to its exact site, phase, authority and conditions. Check later amendments, withdrawals and restrictions. Missing public fields remain unknown; membership does not turn an uncertain claim into a verified fact.

Reading Illinois data center construction activity

Use the public previews on this page to compare locations and recorded development stages before choosing which project to investigate. These are records in Radar’s research set, rather than a complete inventory of Illinois facilities or available contracts.

Start with the location and recorded stage

The available previews include Aurora, Batavia, Braidwood, Carol Stream, Chicago, Chicago (South Loop) and other locations. Use the recorded city to keep Chicago-area searches separate from projects elsewhere in Illinois. A campus or phase may have its own record.

In this public set: Under Construction (9 records); Approved (7 records); Status under review (6 records); Announced (3 records); Planned (2 records); On Hold (2 records); Site preparation (1 record); Partially operational (1 record). These labels describe the records; they do not establish that bidding is open.

Follow the local approval history

A local decision applies to the jurisdiction and work described in its source. A council position, an adopted restriction and an extension recommendation belong on separate lines of a timeline. Troy’s public approval history shows those distinctions and the dates of the supporting records.

Choose the next document to check

Use the relevant local planning record, adopted decision or applicable permit to answer one specific question. Confirm what was requested or authorized, which body acted and what remains unresolved. Keep the event date separate from the date the research was checked.
