Grid & water — why here
source: HIFLD · EPAThe closest existing grid infrastructure and the municipal water system this location sits in — the same constraints the buildout model screens on (it won't site a campus more than ~2 km from a substation or ~5 km from municipal water). Distances are straight-line to public HIFLD/EPA features, not a metered connection.

Tax breaks & subsidies
source: Good Jobs First / GASB 77No per-deal tax break is linked to this site yet. No state discloses the recipient of a data-center abatement at the facility level, so per-site deals are rare in the public record. If you have a development agreement or board resolution for this site, send it to us.
Water use
No measured record exists, so this is a low-confidence model from 50 MW (disclosed IT power): 2 L/kWh cooling (hot climate) + 0.45 gal/kWh embedded in US grid average. How we estimate. Have a utility document? Send it and we'll replace this with the real figure.
