Operational facilities statewide, the densest concentration in the world
Share of Virginia electricity consumed by data centers, projected to reach 40 to 50 percent by 2035
Drop in Virginia community support for new data center construction, 2023 to today
Northern Virginia hosts the original peering points for the eastern United States internet. When the first commercial cloud data centers were built in the late 1990s, they followed the fiber. Loudoun County offered abundant land, low electricity rates, and a tax exemption for data center equipment that has been renewed and expanded for over two decades.
The result is the densest contiguous cluster of data center capacity in the world. Industry estimates put roughly 35 percent of global internet traffic flowing through Virginia. Most major cloud and AI operators have anchor presence in Northern Virginia. The downstream effect is accelerating electricity demand, rising community concerns about water and noise, and visible political pressure on the General Assembly to revisit the tax preferences.
The Loudoun core (Ashburn, Sterling, Dulles) is at or near grid capacity. Permitting velocity has slowed and local opposition has stiffened. New applications are spilling over to:
Dominion Energy, the dominant utility, has filed integrated resource plans projecting that data centers will consume 40 to 50 percent of state electricity by 2035 if all pending applications come online. The Virginia State Corporation Commission is actively considering rate-class separation that would isolate data center customers in their own tariff and protect residential rates.
Without rate-class separation, the cost of new generation, transmission, and grid capacity built primarily to serve data centers is allocated across all customer classes. Recent SCC filings show the residential rate impact is real and measurable.
Most Northern Virginia data centers use evaporative cooling, drawing on local potable supply. Water utilities in Loudoun and Prince William have raised concerns about long-term capacity given the projected build-out. Several recent projects have been required to use reclaimed water or to fund new infrastructure as a condition of approval. This is a pattern other Virginia jurisdictions are beginning to mirror.

Virginia hosts the densest concentration of data centers in the world. As of 2025, the state has roughly 300 operational data center facilities, with the largest cluster in Loudoun County, followed by Prince William, Fairfax, Henrico, and Fauquier. New applications continue at a pace of 30 to 60 per year statewide. Northern Virginia handles an estimated 35 percent of global hyperscale data center traffic.
Data centers consume more than 25 percent of all electricity sold in Virginia, the highest data center share of any US state. Dominion Energy, the dominant utility, has filed multiple integrated resource plans projecting that share to grow to 40 to 50 percent by 2035 if pending applications materialize. The State Corporation Commission is actively reviewing rate structures specifically because of data center load.
Three factors: existing fiber infrastructure (Northern Virginia houses the original peering points for the eastern US internet), historically lower electricity costs and abundant land in Loudoun and Prince William, and a state and county tax incentive structure that has rewarded data center investment heavily over the past 20 years. Recent grid constraints and rising community opposition are starting to shift new applications to Henrico, Fauquier, and Hampton Roads.
Polling shows community support for new data center construction in Virginia dropped from 69 percent in 2023 to 35 percent in recent surveys. The shift is driven by visible electricity rate increases, water sourcing concerns, generator noise complaints, and several high-profile referendum challenges in Loudoun, Prince William, and Fauquier counties.
Virginia exempts data center equipment from state and local sales tax under a tax preference renewed multiple times. The exemption is estimated to cost the state hundreds of millions of dollars per year in foregone revenue. Multiple General Assembly sessions have considered adding sunset or local-control provisions; none have passed.
Air permits are required for backup generator emissions and trigger Virginia DEQ review under the Clean Air Act. Water withdrawal requires DEQ permitting if it exceeds threshold quantities. Local zoning is the gating step for new sites. Virginia does not require a state-level cumulative impact assessment for clusters of data centers, which is a common community ask in current public hearings.
Three intervention points: zoning hearings (county supervisors, planning commission), air permit comment periods (DEQ), and electricity rate dockets (State Corporation Commission). Each has its own procedural rules and comment windows. The most leverage is at the county zoning stage, before approval. Specific data on emissions, water sourcing, and rate impacts changes the conversation more than generic opposition.
Loudoun County has the largest concentration with over 35 million square feet of data center space and growing. Prince William, Fairfax, and Manassas Park follow. Henrico is now the fastest-growing market by approved megawatts. Fauquier, Stafford, Spotsylvania, and Hampton Roads jurisdictions are absorbing applications that have been delayed or denied in Northern Virginia.
Northern Virginia hosts the largest contiguous data center market in the world, estimated at over 4 gigawatts of installed IT capacity with another 3 to 4 gigawatts in active development. The Ashburn corridor in Loudoun County, sometimes called Data Center Alley, holds the highest concentration. Industry estimates put roughly 35 percent of global internet traffic flowing through Northern Virginia data centers.
Virginia leads the US in installed data center capacity, ahead of Texas, Arizona, Georgia, and Ohio combined. The next wave of growth is shifting to other states because Northern Virginia grid capacity is constrained and community opposition has slowed approvals. Texas (especially the Austin and Dallas corridors), Phoenix-area Arizona, Atlanta-area Georgia, and Columbus Ohio are now the second-tier growth markets.
