Prince William County, Virginia has dealt back-to-back blows to large-scale AI infrastructure development, voting unanimously to block a proposed 43-million-square-foot data center campus just days after QTS withdrew its appeals on the $30 billion Digital Gateway project.
What Was Rejected
The Board of County Supervisors voted 8-0 against initiating Comprehensive Plan Amendment CPA2026-00012 for the Dulles South Innovation Center. The proposal would have converted approximately 1,940 acres across 252 parcels of agricultural land in the Gainesville District into an industrial campus including data centers, electrical substations, and related facilities. County planning staff had recommended against the amendment before the hearing, and the Planning Commission had already voted 5-1 to recommend denial.
Unlike the Digital Gateway project, which was located along an established industrial corridor west of Manassas, the Dulles South campus would have pushed large-scale data center development into rural western Prince William County, south of Washington Dulles International Airport.
Community and Political Opposition
Residents opposing the plan raised concerns about transmission infrastructure, substation scale and placement, groundwater impacts, noise, traffic, and the broader industrialization of the county’s Rural Area. Property owners inside the project boundary offered a counterpoint, arguing that data centers could generate tax revenue and economic opportunity that traditional agriculture cannot provide.
Virginia State Senator Danica Roem used the hearing to repeat her call for a statewide pause on new data center approvals while Virginia assesses cumulative community and grid impacts.
What the Consecutive Rejections Signal
Analysts contacted by Data Center Knowledge framed the two decisions as a shift in risk calculus rather than a collapse in underlying demand.
Independent strategist Ihab Osman described it as a “repricing of entitlement risk.” He noted that Northern Virginia retains its structural advantages in fiber density, cloud ecosystem concentration, and utility experience, but said developers are now asking a different question of prospective sites.
“It is no longer enough to ask where power, fiber, and land exist on paper. The more serious market screening now asks where those inputs are politically usable,” Osman said.
Neil Osnato, founder of Persistence Analytics Group, added that local governments are no longer automatically converting data center demand into land-use approval, a shift with direct consequences for utilities and grid planners.
Implications for Grid and Infrastructure Planning
Osnato identified a planning gap that the rejections expose. Utilities and regional transmission planners have been forecasting rapid electricity demand growth driven by AI infrastructure, but those forecasts depend on projects actually reaching construction.
- Land-use approvals
- Power deliverability and transmission timing
- Substation capacity
- Water availability
- Sustained community and political support
“If any one of those assumptions breaks, the site is not truly executable,” Osnato said. He cautioned that utilities risk building or allocating infrastructure around announced demand that may never materialize if entitlement durability continues to erode.
For hosting operators and enterprise buyers evaluating Northern Virginia colocation or cloud capacity, the practical takeaway is that new large-scale supply in the region faces a longer and less predictable approval path than it did even a year ago.
