Disturbance Control Standard-Contingency Reserve for Recovery From a Balancing Contingency Event Reliability Standard

The Commission approves Reliability Standard BAL-002-2 (Disturbance Control Standard--Contingency Reserve for Recovery from a Balancing Contingency Event) submitted by the North American Electric Reliability Corporation (NERC). Reliability Standard BAL-002-2 is designed to ensure that balancing authorities and reserve sharing groups balance resources and demand and return their Area Control Error to defined values following a Reportable Balancing Contingency Event. In addition, the Commission directs NERC to develop modifications to Reliability Standard BAL-002-2 to address concerns regarding extensions of the 15-minute period for Area Control Error recovery and contingency reserve restoration. The Commission also directs NERC to collect and report on data regarding additional megawatt losses following Reportable Balancing Contingency Events during the Contingency Reserve Restoration Period and to study and report on the reliability risks associated with megawatt losses above the most severe single contingency that do not cause energy emergencies.
