Ashburn transmission fault drops over 3GW of data center load from Virginia grid
A transmission line failure in Ashburn, Virginia on July 22, 2026 removed more than 3 gigawatts of demand from the grid within seconds, highlighting the fragility of power delivery in the world's largest data center hub. The incident follows a similar event two years earlier, when a single failed surge arrester took roughly 60 Virginia facilities offline. Together the outages point to transmission architecture, rather than generation alone, as a growing constraint on AI buildouts.
