3 gigawatts vanished in seconds exposing an AI grid risk
a single fallen line caused 3.1 gw of data centers to cut power simultaneously, flickering lights across the pjm grid and signaling that ai energy loads are destabilizing regional infrastructure.
after a single line fault, data centers in northern virginia drew down 3.1 gw in 30 seconds and eventually shed 3.49 gw, causing voltage spikes across the pjm interconnection. experts warn this synchronized response creates a 'canary in the coal mine' scenario where high-density computing clusters threaten grid stability. without upgrades to uninterruptible power supplies or staggered reconnection protocols, the electrical grid will struggle to maintain the near-perfect balance required as ai demand accelerates.
