Today’s LiveWire Spotlight evaluates two NERC’s Lessons Learned related to Energy Management System (EMS) failures that other Registered Entities may learn from and avoid. In addition, the guidance documents offer Lessons Learned in training, tool upgrades, maintenance preparation, and troubleshooting that aim to make recurrences less likely.

Electric system outages that result from EMS failures continue to be one of NERC’s top reliability concerns. New reliability requirements could result if these Lessons Learned do not reduce the incidence of these types of threats.
