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.

Water use
No measured record exists, so this is a low-confidence model from 75 MW (interconnection capacity): 1.8 L/kWh cooling (temperate climate) + 0.5 gal/kWh embedded in PJM grid mix. How we estimate. Have a utility document? Send it and we'll replace this with the real figure.

32 MW of load at the zone's $333/MW-day, annualized — the capacity charge a load this size carries at the current auction price.
Separately, a typical home in this zone pays an estimated $4 to $10/mo more on the capacity portion of its bill that PJM's market monitor attributes to data-center demand. See your address's full impact →
