U.S. largest grid updates emergency plan as AI stretches capacity
PJM Interconnection LLC, the largest U.S. power grid serving 13 states, is implementing a new "capacity advisory" emergency warning. This action is a direct response to surging electricity demand driven by data centers and artificial intelligence, which is pushing power supplies toward shortages even outside of extreme weather conditions. The advisory will help manage grid capacity and ensure sufficient generation.
PJM Interconnection LLC, the largest U.S. power grid operator responsible for supplying electricity to 67 million people across 13 states, has agreed to introduce a new "capacity advisory" warning. This measure is a direct response to the escalating power demands from data centers, particularly those fueling artificial intelligence, which are now straining electricity supplies beyond periods of extreme weather.
According to Paul Dajewski, a senior manager at PJM, the grid has already experienced capacity emergency situations without the typical triggers of hot or cold weather. The new advisory, set to be issued three to five days in advance of potential emergencies, aims to ensure sufficient generation by prompting power plants to reschedule maintenance and alerting other regional grid operators.
This move signifies a broader shift in how grid operators are adapting procedures to cope with the burgeoning electricity consumption by data centers. The grid operator, whose service area includes "data center alley" in Northern Virginia, also approved the enhanced use of back-up generators in emergency scenarios, pending approval from the Department of Energy. This follows an emergency load-management alert PJM issued last month in response to high temperatures, signaling ongoing challenges in meeting demand.
