Gemini Data Center (Sioux Falls, SD)

Sioux Falls, Minnehaha County, SD

Gemini Data Center (Sioux Falls, SD) is a planned data center in Sioux Falls, SD, with Gemini Data Center SD, LLC named as the developer. Reported capacity is 500 MW. Proposed hyperscale data center on a ~160-acre parcel (145.6 acres rezoned) between Sioux Falls and Brandon, SD, near Veterans Parkway and Rice Street, northeast Sioux Falls. Reported capacity ~500MW. City had approved annexation in Oct 2025; City Council unanimously (7-0) approved rezoning from agricultural to light industrial on Jan 7 2026 after ~4 hours of public comment, mostly opposed (a later petition drive to force a referendum on the zoning failed). End-use tenant/hyperscaler behind Gemini Data Center SD LLC not disclosed in source. Facility restricted to domestic-only water use from the city (not cooling); developer says it plans a closed-loop cooling system but has not fully committed. Rezoning approval does not guarantee development -- still requires site plan approval and building permits.
