A large-scale disconnection event disrupted PJM Interconnection, the electric grid serving more than 65 million people across 13 states, according to Reuters. The incident adds fresh urgency to ongoing debates about grid reliability as data center and AI load continues to climb across the PJM footprint. PJM has been under pressure from regulators and the White House to reform its governance and interconnection queue processes. The timing of the event, during a period of elevated summer demand, will likely accelerate calls for infrastructure investment.
PJM is the most heavily loaded grid region in the country and home to the densest concentration of data center demand on the East Coast. A major disconnect event there signals that existing infrastructure is being tested at a moment when new gigawatt-scale loads are still queuing for connection.
Named grid operator PJM, Reuters sourcing, and direct link to data center load growth triggered selection. Grid reliability failures at PJM carry broader industry consequences than similar events at smaller regional operators, ranking this above other power stories in this run.
