Today’s LiveWire Spotlight looks at three incidents where Operations systems data integrity affected electric system performance, and which other Registered Entities may learn from and avoid. The Lessons Learned explore the effect of data quality on the systems that support Real-time operations through the study of actual events that manifested themselves in very different ways.

Electric system outages that result from poor operations data quality 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.
