Provider notes
Energy. 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.
Water. Closed-loop direct-to-chip cooling saves millions of gallons vs evaporative; family water rights held by founders; no new water allocation required
Community. The Millard County Commission approved the project (Aug 2025) and it is widely framed as a landmark rural-Utah investment (part of Gov. Cox's Operation Gigawatt). Local coverage also notes resident concern about the campus's scale, off-grid gas generation, and water; the founders' family holds the water rights. No organized opposition or litigation surfaced.
What the source record says
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.
Any MW value is reproduced as source-reported context. Its measurement boundary is not established consistently enough for comparison. Unknown is not zero.

Compute Atlas 1.34.1 with retained prior rows and publication holds. This is a DataCenterData composite, not an unmodified publisher edition. This row uses the captured source from 1.34.1, source as of 2026-10-14T20:40:52.293Z.
That does not mean the row is wrong, and it does not mean no reviewed record exists for the same place. A link is added only when an identifier or source establishes the match.
