Virginia becomes world’s data‑center capital, spurring growth and resource strain

Northern Virginia now hosts the world’s largest concentration of data centers, with 71 operating facilities in Loudoun County and 131 statewide according to a 2024 Joint Legislative Audit and Review Commission study. The cluster grew from early internet hubs such as AOL’s 1997 relocation and the UUNet/WorldCom exchange, leveraged proximity to the federal government, and was boosted by a 2008 state sales‑and‑use‑tax exemption.

The boom has delivered significant economic benefits for local governments, but communities are increasingly concerned about the heavy water and energy demands of the facilities. House Technology Committee Chair Cliff Hayes said the designation of Virginia as a “digital capital” required “stamina, resilience and vision,” while lawmakers this year passed a package of bills aimed at tighter regulation. The debate over tax incentives for data‑center developers remains unresolved.

The rise of artificial‑intelligence workloads is accelerating demand for the warehouse‑like facilities that store and process data. Virginia Tech professor Ali Mehrizi‑Sani noted that most customers are federal agencies and contractors, making proximity to Washington, D.C. a key driver. Buddy Rizer, executive director of Loudoun County Economic Development, recalled that “you can’t overstate the importance of AOL” in making the internet mainstream and anchoring the region’s infrastructure.
