1. Steve Rueckert Director of Standards Standards Update June 5, 2014 Joint Guidance Committee Meeting Salt Lake City, UT

2. 2 WECC Regional Reliability Standards o Recent FERC Approval o Current Projects NERC Projects Overview

3. 3 FERC issued a Letter Order Approving IRO-006-WECC-2 on May 13, 2014 Effective July 1, 2014 No impact on BA or RC requirements Updated to remove the reference to a specific WECC Unscheduled Flow Mitigation Plan and instead refer to the currently effective Plan regardless of which one it is Recent FERC Approval IRO-006-WECC-2

4. 4 Proposal to lower the applicable facility thresholds for generator testing and validation identified in recently approved NERC MOD standards Proposal to modify the periodicity Would become a Regional Variance to the NERC Standards Would reflect current WECC Policy Current WECC Regional Standards Activities WECC-0101 - Generator Validation Policy Conversion

5. 5 VAR-002-WECC-1 (AVR) VAR-501-WECC-1 (PSS) Proposing to delete R2 in both Standards and move it to the Measure for R1 Ballot Pool Formation 5/28 – 6/19 Ballot Window 6/25 – 7/18 Current WECC Regional Standards Activities WECC-0105 – P81 Revisions

6. 6 INT-018-WECC-RBP-1 No changes to the Definitions of the Codes No changes to the requirement to use the Codes Formatting o Moved actual definitions to the WECC Glossary Ballot Pool Formation 5/28 – 6/19 Ballot Window 6/25 – 7/18 Current WECC Regional Standards Activities WECC-0106 – Energy Product Codes

7. 7 Originated from an RPIC assignment to review documents for appropriate categorization WECC CWG identified several PSS documents that are related to reliability and should be considered for inclusion in regional reliability standards The Drafting Team is still working on the first draft Current WECC Regional Standards Activities WECC-0107 – PSS Design and Performance

8. 8 84 WECC TOs will have to conduct an assessment (Requirements R1 and R2) on approximately 687 substations o 338 500 kV o 81 345 kV o 268 230 kV Unknown without the assessments how many substations, if rendered inoperable, will result in widespread instability, uncontrolled separation, or Cascading NERC Physical Security Standard Impact on the Western Interconnection

9. 9 NERC Board of Trustees Adopted the Standard on May 13 NERC filed the Standard with FERC on May 23 Expectation is that FERC will act quickly NERC Physical Security Standard Next Steps

10. 10 THE INITIAL RISK ASSESSMENT REQUIRED BY R1 MUST BE COMPLETED ON OR BEFORE THE EFFECTIVE DATE OF THE STANDARD Physical Security Standard BE AWARE
