About This Metric
The Disturbance Control Standards (DCS) Failures metric measures the Balancing Authority’s (BA) or Reserve Sharing Group’s (RSG) ability to balance resources and demand with contingency reserve, thereby returning the interconnection frequency within defined limits, following a Reportable Disturbance. The relative percentage and disturbances greater than the Most Severe Single Contingency provides an indication of performance measured at a Balancing Authority or Reserve Sharing Group. NERC Standard BAL-002 requires that a BA or RSG evaluate contingent BA or RSG performance for all reportable disturbances and report findings quarterly to NERC.
