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
Tax abatements or other public subsidy
Which utility serves it

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.
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.
Which utility serves it: The electric service agreement or the utility's filing with the state public utility commission.

Have one of these documents? Send it to us and we will add it to the record with attribution.
