CleanArc Data Centers has begun construction on a 900-megawatt hyperscale campus in Virginia, one of the largest single data center projects announced in the state. Virginia remains the world's densest data center market, and the CleanArc project adds significant load to an already strained regional grid. The groundbreaking follows a wave of similar announcements as hyperscalers race to secure compute capacity for AI workloads. State utility regulators will face pressure to identify power supply for the facility before it reaches full capacity.
