AI Data Centers in Virginia: Data Center Alley Explained (2026)

Virginia hosts the largest concentration of AI and cloud data center capacity in the world, centered on Loudoun County's "Data Center Alley." Ban the Bots' data center map tracks four major facilities there as of 2026, totaling more than 8,300 megawatts — nearly double the tracked capacity of the state with the next-largest buildout, Texas.

Which companies operate data centers in Virginia?

Northern Virginia's cluster is shared by Amazon Web Services, Microsoft, Google, and Meta, who collectively operate the Loudoun County cluster, plus dedicated AWS and Microsoft campuses further south and west in the state.

Why is Virginia the biggest data center market on Earth?

Loudoun County, Virginia — home to Ashburn, sometimes called "Data Center Alley" — hosts over 25% of global internet traffic passing through its facilities, according to Loudoun County's own government data. That concentration exists because early internet infrastructure (including major fiber routes and the original AOL campus) was built there in the 1990s and 2000s, and each new hyperscale buildout since has clustered around the existing fiber, substations, and skilled workforce rather than starting from scratch elsewhere.

Water, power, and community pushback

Virginia's data center boom has produced some of the most visible community opposition of any state on this site's map:

• Amazon Web Services' Prince William County expansion near Manassas — a proposed 2,000+ acre campus near the Manassas Battlefield — drew major community opposition over sprawl, traffic, and water before Virginia approved it in 2023.
• The Northern Virginia cluster itself draws from the Potomac River watershed via Loudoun Water, and its ongoing expansion is straining the county's power grid, per Loudoun County's own reporting.
• Microsoft's Boydton facility in Mecklenburg County — including its LVL, East Coast, and Timber data centers — draws on the Dominion Energy Virginia grid and represents over $2 billion in cumulative investment since 2010.

Virginia AI data center facilities, one by one

• Northern Virginia Data Center Cluster ("Data Center Alley") (Loudoun County, Ashburn; operating): shared by Amazon Web Services, Microsoft, Google, and Meta, with roughly 4,500 MW of tracked capacity — the largest data center market in the world, hosting over 25% of global internet traffic per Loudoun County.
• Amazon Web Services Northern Virginia Expansion (Manassas, Prince William County; under construction): a proposed 2,000+ acre campus near the Manassas Battlefield, drawing on the Occoquan Reservoir via the Prince William County Service Authority, approved by Virginia in 2023 despite community opposition over sprawl, traffic, and water.
• Microsoft Boydton East Coast Data Center (Mecklenburg County; operating): multiple hyperscale buildings — including the LVL (450.5 MW), East Coast (412.5 MW), and Timber (223.5 MW) data centers — all operational as of 2023, drawing on the Dominion Energy Virginia grid, with $2B+ invested cumulatively since 2010.
• AWS Caroline/Spotsylvania County Virginia Campus (Bowling Green; under construction): a 1,143-acre campus spanning Caroline and Spotsylvania counties, with 11 two-story buildings targeting 770 MW operational by 2027.

FAQ: AI data centers in Virginia

How many AI data centers are in Virginia?

Ban the Bots tracks four major facilities/clusters in Virginia as of 2026 — the Northern Virginia (Loudoun County) cluster shared by AWS, Microsoft, Google, and Meta, plus dedicated AWS campuses in Prince William and Caroline/Spotsylvania counties and a Microsoft cluster in Mecklenburg County — with more than 8,300 megawatts of combined tracked capacity, the largest of any state on this site's map.

Why is Northern Virginia called "Data Center Alley"?

Loudoun County, Virginia, hosts over 25% of global internet traffic, according to the county's own government data, a legacy of early internet infrastructure built there in the 1990s and 2000s that later hyperscale buildouts clustered around.

Has there been community opposition to data centers in Virginia?

Yes. Amazon Web Services' proposed campus near the Manassas Battlefield in Prince William County drew significant community opposition over sprawl, traffic, and water before Virginia approved it in 2023, and Loudoun County's own reporting notes that its cluster's continued expansion is straining the local power grid.

What water sources do Virginia's data centers use?

It varies by facility: the Northern Virginia cluster draws from the Potomac River watershed via Loudoun Water, and the Prince William County expansion draws from the Occoquan Reservoir via the Prince William County Service Authority.

Conclusion: tracking Virginia's AI buildout

Virginia's data center capacity dwarfs every other state tracked on this site, concentrated in one of the most fiber-dense corners of the internet — with real local costs in water, power, and land that have already triggered organized community pushback.
