    Phase 2 OverviewApproaching mid-point of the action plan to implement recommendations from the 2012 GMD Report Several project plan tasks are expected to complete in 2013Provide additional open-source tools for industry to assess risks and evaluate mitigation strategiesStrong collaboration with EPRI, NATF, government, and private sector researchers

    Stage 1: Operating ProceduresStandard(s) that require entities to implement Operating Procedures to mitigate the effects of GMDsRequirements should allow procedures to be tailored based on entity-specific factors such as geography, geology, or topologyConsider coordination of procedures across regionsBoard approval by November 2013

    RELIABILITY | ACCOUNTABILITY*

    Stage 2: Assessments and MitigationDevelop Standards that require assessment of benchmark GMD events and strategies to mitigate identified impactsResearch and tools being produced through the GMD Task Force Phase 2 project provide the technical foundationBoard approval by November 2014

    RELIABILITY | ACCOUNTABILITY*

    PurposeTo mitigate the effects of geomagnetic disturbance (GMD) events by implementing Operating Procedures

    RELIABILITY | ACCOUNTABILITY*

    ApplicabilityReliability CoordinatorsTransmission Operators and Balancing AuthoritiesLimited to those with an area that includes any transformer with high side terminal voltage greater than 200 kVEffects of GMD on systems below 200 kV are far less due to higher line resistance (see Chapter 8 of 2012 GMD Report)http://www.nerc.com/pa/RAPA/ra/Pages/default.aspx

    RELIABILITY | ACCOUNTABILITY*

    Reliability CoordinatorsEach Reliability Coordinator shall develop, maintain, and implement a GMD Operating Plan that includes:A description of activities to mitigate the effects of GMD eventsA process to determine that the GMD Operating Procedures in the Reliability Coordinator Area are coordinated and compatibleProvides a wide-area view for effective coordination

    RELIABILITY | ACCOUNTABILITY*

    Transmission Operators and Balancing AuthoritiesEach applicable entity shall develop, maintain, and implement GMD Operating Procedures that include:Steps for disseminating space weather information to System OperatorsSteps to be employed by System Operators that are coordinated with its Reliability Coordinator to mitigate the effects on the system from GMDPredetermined trigger conditions for initiating and terminating steps or tasks in the Operating ProcedureGMD Task Force Operating Procedure templates provide steps and trigger conditions for entities to consider

    RELIABILITY | ACCOUNTABILITY*

    ImplementationFERC Order specifies six-month implementationIn jurisdictions where regulatory approval is required:Standard becomes effective by the first day of the first calendar quarter, six calendar months following applicable regulatory approvalIn jurisdictions where regulatory approval is not required:Standard becomes effective by the first day of the first calendar quarter, six calendar months following NERC Board of Trustees approval
