Data centers existing or under construction in Northern Virginia as of August 16, 2024.

GIS and tabular data on data center locations was obtained from each local jurisdiction in Northern Virginia that currently have data center development. This data was cross-checked with aerial imagery, Baxtel's data center map and individual data center information, Data Center Map's data, building permits, and real estate property assessment records. Data centers planned but not under construction, as well as proposed data centers, were excluded. Data centers were added if they were determined from the cross-check to be under construction or completed since the time the local jurisdictions published their data. Data centers were also added if they were simply missing or misclassified as some other structure type in the local jurisdiction data.
