Notes on the record
aiClassification is 'likely' (not 'confirmed'): Gemini is the land developer, no tenant is signed, and only developer aspiration to attract a hyperscale/AI/neocloud tenant is on record. Capacity (500 MW) and acreage per SiouxFalls.Business; an earlier report cited 160 acres. Coordinates are approximate for the northeast Sioux Falls site. As a developer land project with no signed tenant, its water, subsidy, investment, and job figures remain developer projections only (South Dakota has no state income tax and rejected data-center incentive bills); all recorded as honest-zeros pending a confirmed tenant.
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.
- Cooling method and water use
- Tax abatements or other public subsidy
- Permanent jobs promised
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.
