PJM Interconnection will study rule changes after a 3,800 MW data-center outage in northern Virginia on July 22.
A 230-kV line fault in the zone cut load 3.8% to 96,205 MW from 99,984 MW.
PJM restored the control-error limit in nine minutes, under the 30-minute NERC standard.
Emanuel Bernabeu said data centers disconnect too early because they are voltage-sensitive.
Matthew Wharton said PJM is reviewing ride-through standards while NERC targets Dec. 31 per FERC directive.
