42311 Thunderball Drive (Compass Datacenters — "True North Data" / Loudoun County I) is a campus data center in Leesburg, Loudoun County, VA. True North Data Solutions is identified as the operator, and the facility is proposed. It is identified as part of Loudoun County I (Compass Datacenters). Spatial service-territory evidence associates the site with Northern Virginia Electric Cooperative; the profile assigns the asset to PJM through that documented market role. Reported development, power, and commercial facts retain their source-specific facility, campus, building, or phase scope; the page does not collapse those values into a single implied load.

- Construction: Compass Datacenters’ ‘‘True North Data’’ (branded Loudoun County I) is a proposed data‑center campus on a 97‑acre parcel at 42311 Thunderball Drive in Leesburg, VA. The site is approved under earlier plans for 750,000 sqft across 9 buildings but Compass sought a modification to reduce the planned data center space to 625,000 sqft (and to eliminate two building footprints and allow an option to consolidate three approved buildings into one). The developer reported the site has been partially cleared and that construction of a one‑story data center building has commenced; the campus is planned to ultimately provide about 75 MW of power at full build‑out. Public hearings on ZCPA‑2020‑0003 were scheduled in 2021–2022 and the applicant deferred hearings while seeking a tenant.
