WECC Criterion – PRC-012-WECC-CRT-1

RAS Review/Assessment Plan

Posting #3

August 22 through September 22, 2016

Criterion Development Timeline

This section is maintained by the drafting team during the development of the criterion and will be removed when it becomes effective.

Nomenclature Change

The nomenclature of this document is proposed for change from PRC-(012 through 014)-WECC-CRT-2.1, Remedial Action Scheme Review and Assessment Plan to PRC-012-WECC-CRT-1, Remedial Action Schemes. The change aligns the WECC Criterion with a single NERC Standard bearing similar content.

NERC Standard, PRC-012-2, Remedial Action Schemes, was approved by a NERC Ballot Pool on April 29, 2016.

Original NERC Standards:

  • PRC-012-0, Special Protection System Review Procedure;
  • PRC-013-0, Special Protection System Database, and;
  • PRC-014-0, Special Protection System Assessment.

Description of Current Draft

The WECC-0119B Removal of Reliability Assurer Drafting Team (DT) is recommending retirement of Requirements (WR) 1, 3, 5, 6, and 7 from the existing Version 2 document because the WRs are redundant to peripheral NERC and WECC documents. The applicable entity of each of these requirements is the Reliability Assurer/WECC (RA).

Requirements WR 2, 4, 8 through 12 are not proposed for retirement; however, under the expanded scope of the Standard Authorization Request (SAR) provided by the WECC Standards Committee in June 2016, the balance of the document will be updated to current drafting conventions.

In Posting 1, a white paper was presented providing evidence of redundancy and illustrating how the reliability content would be continued in the event the specified Requirements were retired. Two comments were received in Posting 1. Both agreed the specified Requirements could be retired without creating a reliability gap.

In Posting 2, the DT made further redaction of the RA reference from the predicate of the remaining Requirements as well as associated Measures. Posting 2 represents those changes along with the recommended retirement of the specified Requirements and updating to meet current drafting conventions. During Posting 2 comments were received requesting correction of certain references in Posting 1. Those requests were granted. The changes were errata and not substantive.

In Posting 3, the DT made further changes as follows.

  • That portion of the Guidance Section referencing WECC was deleted.
  • Defined terms were removed from the WECC Criterion in favor of proper nouns. Definitions will be maintained by the Remedial Action Scheme (RAS) Reliability Subcommittee (RASRS). A narrative to that affect will be added in the Guidance Section.
  • WR1 will be deleted as it was only pertinent for start-up of the database that is now in use.
  • WR5 will have a narrative added to the Guidance Section explaining that the requirement does not mandate that all RAS be reviewed at the same time. Staggered review is allowed by the requirement.
  • WR7 was deleted because it was administrative in nature. This is in keeping with NERC’s P81 efforts to delete redundant and administrative-only requirements from the regulatory arena.
  • Attachment A will be deleted except for the Reporting Party field. All other Attachment A information is redundant to the RASRS Procedure to Submit a RAS for Assessment, Information Required to Assess the Reliability of a RAS Guideline, revised October 28, 2013 (Procedure).
  • Attachment A will have a narrative included in the Guidance Section explaining the ownership and maintenance of the RAS database. The existing Attachment A narrative will be included in the new Guidance Section narrative.
  • Attachment B narrative that was duplicated in Attachment A will be removed. Version 1 Attachment B becomes the newly proposed Attachment A for purposes of Posting 3.
  • Corrections will be made to the Posting 1 crosswalk.

Implementation Plan

Because the tasks assigned in the specified Requirements are covered in other documents the DT foresees no change in operational or business practices. As such, the DT is recommending the document be made effective immediately on approval by the WECC Board of Directors.

New or Modified Term(s) Used in the WECC Glossary for WECC Criteria and Naming Conventions (WECC Glossary).

This section includes all new or modified terms used in the proposed criterion that will be included in the WECC Glossary upon applicable approval. The new or revised terms listed below will be presented for approval with the proposed document. Upon WECC Board of Director (Board) adoption, this section will be removed and the approved terms will be moved to the WECC Glossary.

The following term is proposed for deletion in favor of a lower case generic description.

Obsolete Definitions:

This WECC Criterion refers to the following obsolete defined terms in the WECC Glossary. This DT does not have the depth of subject-matter expertise to update these definitions. The DT is referring the matter to the Remedial Action Scheme Review Group.

  • Local Area Protection Scheme (LAPS); refers to TPL-(001 thru 004)-WECC-1-CRT. That document no longer exists.
  • Safety Net; refers to TPL-004-0. That document no longer exists.
  • Wide Area Protection Scheme (WAPS); refers to TPL-(001 thru 004)-WECC-1-CRT. That document no longer exists.

Term for Deletion:

Attachment A

WECC RAS Initial or Periodic Assessment Summary

Information on Attachment A will be used by the RASRS to ensure proper analysis, operation, coordination and effectiveness of the RAS.

RAS Name
Reporting Party
The Reporting Party is identified using the following criteria:
1) The Transmission Owner is the Reporting Party.
2) Where there is not a Transmission Owner that owns a portion of the RAS, the Generator Owner becomes the Reporting Party.
3) Where there is neither a Transmission Owner nor a Generator Owner that owns a portion of the RAS, the Distribution Provider becomes the Reporting Party.
When applying the above prioritization, if multiple entities (e.g. multiple Transmission Owners in the first described tier) own a portion of the RAS, those multiple entities may designate a single entity from that group to serve as the Reporting Party.
If a single Reporting Party is not designated, all of the entities of the specified prioritization tier become responsible as the Reporting Party.
Group Conducting this RAS Assessment
Assessment Date

Rationale

A Rationale section is optional. If Rationale Boxes were used during the development of this project, the content of those boxes appears below.

Guidance Section

RAS Classifications

RAS classifications such as Wide Area Protection Scheme, Local Area Protection Scheme, and Safety Nets are addressed by the Remedial Action Scheme Reliability Subcommittee, under the auspice of the Operating Committee, in the Procedure to Submit a RAS for Assessment, Information Required to Assess the Reliability of a RAS Guideline, as updated from time-to-time. Definitions for these terms were contained in Version 1, Attachment A of this document, but have shifted directly to the RASRS. As a result the terms are no longer included in the WECC Glossary of Terms and Naming Conventions.

Role of the RASRS and the WECC RAS Database

When the first version of this document was approved it met the NERC fill-in-the-blank (FITB) requirement to establish a WECC RAS database. The initial version required completion and submittal of a data set regarding RAS from which the WECC Remedial Action Scheme Reliability Subcommittee (RASRS) created the WECC RAS database. It is the WECC RASRS that maintains that database. The FITB standards described a discrete minimum data set for inclusion in the WECC RAS database but were silent on WECC’s ability to expand on that minimum.

Since the RASRS maintains the database, the RASRS also maintains the procedure whereby the database is populated. Instructions and explanations regarding the database are currently found in the Procedure to Submit a RAS for Assessment, Information Required to Assess the Reliability of a RAS Guideline, Revised: October 28, 2013, see pages 9 and 10 (Procedure). Because the Procedure is owned by the RASRS under the auspice of the Operating Committee (OC), its contents may change from time-to-time under the due process rules of the OC. Questions about that document should be directed to the RASRS.

WR4

WR4 does not require that all RAS be reviewed at the same time, only that each RAS is reviewed at least once each five years. Staggered review is allowed under the requirement.
