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.
