Criterion Development

This section is maintained by the drafting team during the development of the document and will be removed on final disposition of the document.


Changes made to the document is response to Posting 3 were substantial. All changes can be seen on the redline version of the document posted at the WECC-0100 project page on the Posted for Comment accordion. An explanation of changes made can be found in the Posting 3 Response to Comments form located at the WECC-0100 project page on the Submit and Review Comments accordion.

Document Scope

This document is designed to address the substance of TPL-001-WECC-CRT-2.1 (TPL), Requirement WR3 and the requirements imposed by NERC TPL-001-4, Requirements R5 and R6. Standard Authorization Request (SAR) WECC-0100 also provides for review and disposition of Table W-1 associated with the WECC TPL. Table W-1 will not migrate to this document; rather, combined interactive language of WR1, WR2, and WR3 is designed to meet that intent.

Procedural Background

On September 5, 2012, the WECC Board of Directors (Board) adopted a recommendation by the Regional Criteria Work Group (RCWG) changing the designation of this document from a WECC Criterion (CRT) to a WECC Regional Business Practice (RBP). On June 24, 2014, the Board reversed that decision and designated this document as a CRT.

In further keeping with the September 5, 2012 recommendation, on November 28, 2012, a Standard Authorization Request (SAR) was submitted to evaluate whether this document should be drafted as a WECC Regional Reliability Standard (RRS).

On December 19, 2012, the WECC Standards Committee (WSC) accepted the SAR as drafted with specific approval to assign an evaluation team to review the subject matter and return a recommendation to the WSC as to whether the document should be redrafted as an RRS.

On June 26, 2013, the WSC approved the evaluation team’s recommendation to ballot the retirement of TPL-001-WECC-RBP-2.1, WR1, WR2, WR4 and WR5. If approved the retirement would become effective coincident with the Effective Date of NERC’s TPL-001-4, because the content of the WECC Requirements will be resident in the NERC TPL-001-4.

On August 8, 2013, the WSC assigned the original drafting team, augmenting the team during later weeks.

On October 8, 2013, a WECC Ballot Pool voted to retire TPL-(012 through 014)-WECC-RBP-2.1, WR1, WR2, WR4 and WR5 of the Effective Date of NERC TPL-001-4. (The Effective Date is projected for approximately January 1, 2016. It should be noted that the TPL has a staggered Effective Date.)

On November 1, 2013, the WECC-0100 Drafting Team (DT):

Reported completion of the tasks assigned in the WECC-0100 Standard Authorization Request (SAR);

Requested the WECC Standards Committee (WSC) deem the WECC-0100 SAR complete; and,

Requested the WSC accept the DT’s recommendation to proceed with informal drafting in support of an iterative SAR tailored to the remedial needs of TPL-001-WECC-RBP-2.1, System Performance, WR3 as well as a more granular implementation plan of TPL-001-4, Transmission System Planning Performance Requirements Requirement R5 and R6.

The WSC agreed to expand the WECC-0100 drafting team to include the entire Reliability Subcommittee, and accept the drafting team’s recommendation that further drafting continue on remedial language for:

1. TPL-001-WECC-RBP-2.1. WR3;

Table W-1; and,

TPL-001-4, Requirements R5 and R6.

On December 5, 2013, the Board approved the decision to retire portions of the WECC TPL upon the Effective Date of the NERC TPL.

During June 2014, the Planning Coordinating Committee (PCC) conducted a straw poll concluding the most appropriate document categorization for this document should be that of a WECC Regional Criterion.

On June 24, 2014, the Board changed the designation of this document from that of a RBP to that of CRT.

A WECC Criterion

Prerequisite Approvals

· WECC Ballot Pool

· WECC Standards Committee

· WECC Board of Directors

Applicable Entities

Planning Coordinator

Conforming Changes to Other Standards

None required.

Effective Date

The Effective Date is the later of January 1, 2016 or the Effective Date of TPL-001-4, Transmission System Planning Performance, Requirements R2-R6 and R8, subject to required approvals.


The effective date is targeted to coincide with the effective date of TPL-001-4, Transmission System Planning Performance.

Consideration of Early Compliance

The DT foresees no reliability-related issues if an entity chooses to implement the document early; however, entities should continue to adhere to approved WECC Criteria until they are retired.


This document will replace TPL-001-WECC-CRT-“2” that is to be retired as of the Effective Date of this project.

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.
