Loudoun Water - Central System

The 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

No 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.

Statewide cost of this incentive

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.
