Data Center Record.

Reported Built from one source

Hoffman Estates Data Center

How much power it needs, how much water it would use and who would use it have not been disclosed.

The developer's figure is what the company said; what a permit allows is the ceiling a permit sets; measured means observed. Water is in gallons a day or a year, whichever the source stated; a tax claim given as a range shows both ends, each linked to the source that gave it.

Still not public, and where it would show up

The record adds each the day a source gives it. Why these documents.

  • Water useA state water right filing or a water supply agreement.
  • Who would use itA lease announcement or a tenant named in a filing.
  • Power the campus would drawA utility or public service commission docket, an interconnection filing, or an air permit for an on site plant.
  • Who is behind itA land record, a zoning application or a company's own announcement.
  • Jobs and taxAn incentive agreement, a county's economic development filing or a fiscal note.
