Pennsylvania and Virginia tighten data center rules amid mounting power demand concerns.

Data center development is accelerating in Pennsylvania and Virginia, with proposed projects that could sharply expand both states’ capacity, though many remain uncertain and may not be built. Virginia has 352 operating data centers and 391 planned, a pipeline that could nearly triple its current capacity; Pennsylvania has about 88 projects proposed for after 2026, but state officials say only five of more than 100 proposals have operating permits. In response to mounting concerns about energy bills, water, pollution and quality of life, Virginia Gov. Abigail Spanberger has restricted access to state development assistance and expedited permitting for large projects, barred agencies from using nondisclosure agreements for project details and directed agencies to develop further standards. Pennsylvania Gov. Josh Shapiro has also imposed new guardrails, with their effect on the project pipeline still to be seen. Industry representatives say AI-driven growth is intensifying electricity needs, prompting interest in on-site generation, batteries and microgrids to manage demand and reduce strain on the grid.
Cleanview estimates that if all proposed Pennsylvania projects are built, the state’s data-center capacity would rise about 40-fold to 22,000 megawatts. Its count treats each individual building as a data center.
The Pennsylvania pipeline is highly uncertain: Cleanview says 45 projects on its national list have already been canceled, while another 450 have no completion date.
Virginia’s operating data centers total 17,325 megawatts, while the 391 planned projects would add another 34,578 megawatts. Cleanview says Virginia already accounts for roughly 28% of the operating capacity it tracks nationwide.
Spanberger’s executive order applies the cutoff from state site-development assistance and expedited permitting to projects with anticipated peak demand of 25 megawatts or more.
