Surging electricity demand from AI data centers risks fracturing PJM Interconnection, the largest power grid in the United States, according to a new Los Angeles Times report. The grid serves 65 million people across 13 states and Washington D.C., and analysts warn that the pace of large-load interconnection requests is outpacing PJM's ability to manage reliability. Grid operators are weighing rule changes that could delay or reject new data center connections that threaten system stability. The outcome will shape how quickly hyperscalers can expand capacity across the mid-Atlantic and Midwest regions.
