MEMO Date: June 1, 2016 To: WECC Standards Committee (WSC) Subject: WECC-0119, Removal of Reliability Assurer (SAR) PRC-003-WECC-CRT-1.3 (WECC CRT), ARM Procedure The memo requests retirement of the following WECC Requirements (WR) included in the WECC CRT because the WRs are either duplicated in a peripheral NERC Standard or WECC document, or are no longer required. Retirement would be effective as of July 1, 2016 coincide with the effective date of PRC-004-4(i), Protection System Misoperation Identification and Correction. Because the WRs are redundant, retirement will have no impact on reliability. The entire WECC CRT is proposed for retirement because WR1 is addressed in PRC-004-4(i). The balance of the WRs (2-5) are either no longer required or are addressed in peripheral WECC documents. DEPENDING ON THE REASON FOR RETIREMENT THE WSC MAY HAVE THE AUTHORITY TO RETIRE THIS WITHOUT FURTHER DUE PROCESS. IF RETIRED BECAUSE OF REDUNDANCY TO NERC STANDARDS – NO FURTHER DUE PROCESS. SLAM DUNK ON WR1 (PRC-004)….IFFY AS TO THE REST. Deletion of the WRs will address the goals of the SAR by eliminating the current conflict of interest whereby WECC serves both as the entity responsible to complete the assigned tasks as well as the entity responsible for monitoring the adherence to the assigned task. THE FOLLOWING 2 OPTIONS ARE OFFERED AND PERMISSIBLE UNDER THE SAR BUT NOT REQUIRED UNDER THE SAR. OPTION 1: MOVE WR1 TO THE RAS PROCEDURE NOW AND DELETE THE ENTIRE CRITERION. OPTION 2: RETIRE WR1 COINCIDENT WITH THE EFFECTIVE DATE OF PRC-012-2, JULY 1, 2017(?). THE FOLLOWING WOULD BE REWORDED ACCORDINGLY. OPTION 1 This memo also requests relocation of WECC CRT, WR1, into a WECC Regional Guideline, such as the Remedial Action Scheme Design Guide, June 2006 or the Procedure to Submit a RAS for Assessment Information Required to Assess the Reliability of a RAS Guideline, October 28, 2013 (RAS Procedure). Relocation would be effective July 1, 2016. Relocation is allowed under the scope of the SAR. OPTION 2
interconnected transmission system from meeting the performance requirements defined in Reliability Standards TPL-002-0, and TPL-003-0. Scheme Review and Assessment Plan, WR4. Once effective, the performance metrics specific to the TPLs (see LAPS/WAPS definition) will be resident in PRC-012-2. This requirement is being retained in the proposed new PRC-012-2 because that NERC drafting team is convinced that it is not covered by TPL-001-4, Transmission System Planning Performance Requirements. R1.4. Requirements to demonstrate that the inadvertent operation of a RAS shall meet the same performance requirement TPL-002-0, and TPL-003-0) as that required of the contingency for which it was designed, and not exceed TPL-003-0. Remedial Action Scheme Design Guide, June 2006. Procedure to Submit a RAS for Assessment Information Required to Assess the Reliability of a RAS Guideline, October 28, 2013. Tied to Local Area Protection Scheme (LAPS) and Wide Area Protection Scheme (WAPS) definitions as used throughout the RASRS Procedure. Once effective, the performance metrics specific to the TPLs (see LAPS/WAPS definition) will be resident in PRC-012-2. This requirement is being retained in the proposed new PRC-012-2 because that NERC drafting team is convinced that it is not covered by TPL-001-4, Transmission System Planning Performance Requirements. R1.5. Procedure to Submit a RAS for Assessment
Requirements to demonstrate the proposed RAS will coordinate with other protection and control systems and applicable Regional Reliability Organization Emergency procedures. Information Required to Assess the Reliability of a RAS Guideline, October 28, 2013. Coordination with Protection and Control Systems, page 14, Bullet 8. See also: RAS Classifications, p. 9; Information Required to Assess the Reliability of a RAS, page 12, at Bullet 11; RAS Purpose and Overview, page 13, Bullet 6; RAS Design, page 14, at Bullets 8 and 9. R1.6. Regional Reliability Organization definition of misoperation. WECC does not have a regional definition for Misoperation. PRC-04-4(i) creates a NERC-wide definition. Absent a regional definition, the NERC definition controls. R1.7. Requirements for analysis and documentation of corrective action plans for all RAS misoperation. PRC-004-WECC-1, Protection System and Remedial Action Scheme Misoperation. PRC-004-4(i), Requirement R5. Enforceable July 1, 2016. Procedure to Submit a RAS for Assessment Information Required to Assess the Reliability of a RAS Guideline, October 28, 2013. See Periodic Assessments addressing Corrective Action Plans, page 9.
