  • Cooling method and water use
  • Tax abatements or other public subsidy
  • Permanent jobs promised
  • Which utility serves it
Which document closes each gap
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.
Which utility serves it
The electric service agreement or the utility's filing with the state public utility commission.
