NERC Submits Supplemental Information on Reliability Standard BAL-002-2

On March 31, 2016, in Docket No. RM16-7, NERC filed supplemental information in support of its January 29, 2016 petition for the approval of proposed Reliability Standard BAL-002-2, Disturbance Control Standard – Contingency Reserve for Recovering from a Balancing Contingency Event.  The purpose of BAL-002-2 is to ensure the Balancing Authority or Reserve Sharing Group balances resources and demand and returns the Balancing Authority’s or Research Sharing Group’s Area Control Error to defined values following a Reportable Balancing Contingency Event (“RBCE”).  The supplemental information provides clarity regarding the significance of the Most Severe Single Contingency (“MSSC”) as the upper bounds for events that qualify as RBCEs under Reliability Standard BAL-002-2 and the way in which other Reliability Standards are necessary and appropriate to address events beyond MSSC.  NERC suggests that this framework effectively preserves reliability by ensuring that loss due to RBCEs (i.e., events that are less than or equal to the MSSC) is managed according to Reliability Standard BAL-002-2, while events causing losses beyond an entity’s MSSC are supported by Reliability Standards better designed to manage the greater risk posed by such events.
