Pennsylvania's Public Utility Commission has raised alarms that the rapid growth of data centers in the state is putting grid reliability at serious risk, warning that PJM's capacity to serve existing customers could be compromised. The PUC has flagged the pace of new interconnection requests from data center developers as outstripping infrastructure upgrades. Officials have not yet specified what regulatory or legislative actions may follow.
Pennsylvania sits within the PJM interconnection, the largest wholesale electricity market in North America, meaning reliability concerns there have implications well beyond the state's borders. A formal PUC finding of reliability risk could trigger interconnection queue reforms or moratoriums on new large-load approvals across the region.
