Source-reported capacity; not metered consumption. Review underlying documents and notes. Planned capacity may include future phases and is not added to operational capacity here. The source may use facility, grid-feed or IT capacity definitions; consult the linked documents.
Coordinate precision is a source label, not an independent parcel survey. A marker does not confirm utility territory or establish an effect on residential bills.
Reported lifecycle history
- Proposed
Gemini Data Center SD LLC (a California family office under Michael Anvar) acquired ~164 acres from Xcel Energy northeast of Sioux Falls, adjacent to Xcel's Split Rock substation, and sought city approvals for a data center supporting up to 500 MW. Gemini is the land developer, not the operator; no tenant is signed.
Underlying source - Permitted
Sioux Falls City Council approved annexation (October 8, 2025) and unanimously approved rezoning from agricultural to light industrial (January 2026), despite hours of opposing testimony. Construction was targeted for 2026 and operation for 2028. The developer committed to funding all utility extensions at its own cost.
Underlying source
Source notes
The AI classification 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); none of them is recorded pending a confirmed tenant.
Site adjacent to Xcel's Split Rock substation and Angus Anson power station; an Xcel facility study is in process. The developer committed to funding utility extensions and substation upgrades.
