Data center load drop destabilized PJM power grid, report says

A data center's load abruptly dropped offline and triggered a voltage disturbance on the PJM grid, the operator serving a large part of the eastern US. The grid reportedly took about ten minutes to stabilize afterward.

Why it matters: This is a concrete, measured instance of AI data center demand destabilizing shared power infrastructure rather than a hypothetical risk, reinforcing warnings from utilities and regulators about the pace of uncoordinated data center growth.
