The largest concentration is Chicago, with 53 data centers, followed by Elk Grove Village with 45 and Aurora with 20. The operators with the most data centers in Illinois are Digital Realty (9), Colocation America (5), Equinix (5), CyrusOne (5), Colovore (5). Colocation and interconnection providers appear most often because they publish building-level detail; hyperscale campuses appear where the operator or the county names the individual buildings. Not every operator discloses size. In Illinois, 57 publish a floor area and 43 publish a power figure, and each figure is shown against the data center it belongs to rather than added into one number. They are not the same measurement: one operator states the floor area of a single building, another the full capacity of a campus it has only announced. PJM runs the wholesale power market and the high-voltage grid for most of Illinois. 2 statewide measures governing data centers are on record, alongside 7 local pauses. 8 named projects in Illinois are delayed, blocked or under challenge, and the capital atlas records 5 sites here carrying $500M in announced commitments. The list ## Illinois data centers by city Every data center identified in Illinois, grouped by the city or county it stands in, 212 of them across 42 places. Each entry names the operator and links to the source that states it. ### Data centers in Chicago, Illinois Chicago, Illinois has 53 data centers on this map, run by Cogent, Lumen, 710facility@ittns.northwestern.edu and CME Group. 13 publish a floor area and 7 publish a power figure, shown against each one below. 1. 11:11 Systems data center - Chicago 11:11 Systems 2. 365 Data Centers Chicago (CH6) 365 Data Centers 427 S.
