Regional guides › Northern Virginia & PJM
AI data centers in Northern Virginia & PJM
The densest data-center market on earth sits inside PJM, where interconnection queues, transmission buildout, and county-level land-use politics now set the pace — not capital. Data-center alley's grid position makes speed-to-power the defining regional constraint.
