What the source record says
Downtown Chicago colocation facility adjacent to the Board of Trade; CoreSite's page states "180,000+" sq ft. Coordinates geocoded from the published street address. CoreSite, L.P. holds a 2020 Illinois Data Center Investment Program MOU for a Chicago site, but the state report does not say which of CoreSite's two Chicago facilities it covers, so no subsidy figure is attributed to this record.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Update this profile with a public source. The request includes topics needing more information; this does not mean the facility lacks them. Corrections and additions are reviewed before publication.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
