Title is held by FIRST DATA REAL ESTATE HOLDINGS L L C, whose name shows single-purpose-entity characteristics (holding-company naming). This is a weak signal only: project-specific entities are routine in ordinary commercial real estate and imply no particular parent.

Gila Substation tagged 69 kV lies 163 m from the site boundary, close enough for a dedicated connection to be practical. Proximity is a locational precondition, not evidence that this substation serves the site.

High-voltage substation in close proximity

Gila Substation tagged 69 kV lies 163 m from the site boundary, close enough for a dedicated connection to be practical. Proximity is a locational precondition, not evidence that this substation serves the site.

Scored by helios-rule-based version 0.1.0 on 2026-07-28, using evidence available as of 2026-07-28. Weights are domain-reasoned starting points, not values fitted to outcomes; calibration is deferred until a historical backtest exists to calibrate against.

Power capacityInferred

13.7 MW

6.9plausible range27.5

Assembled acreage x assumed power density, adjusted for stage.

What this assumes

Power density is an industry assumption, not a property of this site. Helios does not know the building footprint, rack density or how much of the assembled land will be built on.

stage: 7
total acres: 5.72
MW per acre low: 1
MW per acre high: 4
MW per acre likely: 2
stage density multiplier: 1.2

Cooling waterInferred

164,400 GPD

16,560plausible range660,000

Estimated power x assumed cooling water intensity.

What this assumes

Cooling type is not recorded in any source Helios ingests. A closed-loop or air-cooled design approaches zero water use; evaporative cooling can exceed a gallon per kWh. The band is wide because the practice is.

gal per kwh low: 0.1
gal per kwh high: 1
gal per kwh likely: 0.5
