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.

Underlying source
Source notes
Founders Mark McDougal and David Gray converting family 4,000-acre alfalfa farm near Holden. Described by founders as largest private project in Utah history. Partnership with Caterpillar for generator sets; MOU with EnergySolutions for nuclear feasibility study. Part of Governor Cox's Operation Gigawatt initiative. Site at 4,800+ ft elevation for cooling efficiency. Coordinates approximate for Holden, Millard County. Subsidies checked at the municipal tier (2026-09-04): no site-level subsidy. Millard County commissioners are quoted on the record stating the county "did not give either development any special treatment or incentives", and no Millard County CRA/RDA public body is registered on the Utah Public Notice Website. Utah's EDTIF programme excludes data centres and the UCA 59-12-104 sales-tax exemption is self-executing, so no site-level award document exists to find.
Phase 1: 1GW from Caterpillar gas generators with battery storage; potential scale to 4GW (some sources cite 12GW); nuclear exploration underway; adjacent Intermountain Power Project pipeline. Off-grid design.
