What the record does not establish, and the document that would

In every fight on our tracker the decisive fact came out of a public records request. These are the requests for this site.

  • Power capacity in megawatts
  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
Which document closes each gap
Power capacity in megawatts
The utility's large load service agreement, the interconnection request in the grid operator's queue, or the electrical site plan in the permit file.
Cooling method and water use
The water service agreement, any groundwater appropriation permit, and the mechanical narrative in the site plan.
Tax abatements or other public subsidy
The abatement, PILOT, or development agreement approved by the county, city, or development authority, and the state's data center sales tax exemption certificate if one was issued.
Permanent jobs promised
The economic development application or incentive agreement, which usually states a job commitment and a clawback.
