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.

Virginia reported $1B in Data Center Retail Sales and Use Tax Exemption (Va. Code § 58.1-609.3(18)) for FY2024 (Virginia Joint Legislative Audit and Review Commission (JLARC) / Weldon Cooper Center). Program-wide, not attributable to this site.
Water use
No measured record exists, so this is a low-confidence model from 175 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.

Environmental permits
source: Permit registerWhat this site costs the grid
source: PJM RPM auction reportsPJM's capacity auction sets a $/MW-day price that utilities pass on to every household and business in the zone. This site sits in PJM's DOM pricing zone, where soaring data-center demand is a documented driver. See the full zone-by-zone breakdown →
An estimated ~45 to 100 MW of load at the zone's $333/MW-day, annualized — the capacity charge a load this size carries at the current auction price. Estimated from the building footprint at 200 to 400 W/ft² (the typical range for modern data centers). A rough order-of-magnitude figure, not a metered or permitted capacity.
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 →
