Today’s LiveWire Spotlight evaluates the AC Substation Equipment Failure Report issued by a task force commissioned by NERC’s Planning Committee. It follows up on NERC’s findings in the 2013 and 2014 State of Reliability reports that show AC substation equipment failures contribute significantly to wide-area Disturbances.

The close tie between multi-Facility failures and circuit breaker performance will keep AC substation equipment integrity on NERC’s list of chief concerns. Look for CEAs to include a related assessment in their review of an entity’s Internal Controls.
