Illinois data centers, in short
Illinois has 212 data centers identified from primary sources, spread across 42 cities and counties and run by 70 operators. 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.
