DearNAME,
In accordance with the NERC Rules of Procedure, Section 6.2, Field Tests and Data Analysis for Validation of Requirement, WECC is requesting a field test to determine the potential system impacts if BAL-002-WECC-2, Contingency Reserve, Requirement R2 is retired.
Overview
On May 6, 2015, WECC Standard Authorization Request (SAR) WECC -0115 BAL-002-WECC -2 Contingency Reserve, Request to Retire Requirement R2, was submitted requesting the retirement of Requirement R2 and its associated compliance elements (WECC BAL). The SAR asserts that on April 1, 2016, the WECC BAL Requirement R2 will be redundant to BAL-003-1, Requirement R1, Frequency Response and Frequency Bias Settings (NERC BAL).
In Posting 1 of the project, commenters raised concerns that additional supportive evidence was needed to support the request for retirement. Commenters and the standards drafting team agreed to pursue a field test to examine the effects on system reliability in the event the requirement is retired. If approved, the results of the test will be published to the WECC Ballot Pool prior to proceeding to final ballot.
Please find in Appendix A the details of the requested test. If I may be of further assistance please feel to contact me.
Sincerely,
StevenRueckert

Requested Action:Request for Field Trial / Request for WaiverRegional Reliability Standard Name:Contingency Reserve
Regional Reliability Standard No:BAL-002-WECC-2, Require to Retire Requirement R2
WECC Tracking Number:WECC-0115
Sponsor / WECC-0115, BAL-002-WECC-2, Request to Retire Requirement R2 Standards Drafting Team, in coordination with the WECC Standards, Operations, and Compliance Department
Standards Liaison / W. Shannon Black, , (503) 307-5782
Analysis Liaison / Tim Reynolds,, (801) 883-6883, in his capacity as WECC staff liaison to the WECC Performance Work Group, under the auspice of the WECC Operating Committee, a standing committee for WECC.
Request for TemporaryWaiver / Because this field test will examine the potential impacts to reliability in the event that a requirement is retired, this field test requests a waiver of performance and compliance with BAL-002-WECC-2, Contingency Reserve, Requirement R2. The waiver shall remain in effect until such time as the test is terminated.
This request for waiver has been vetted with and approved by the subject matter experts of the WECC-0115, BAL-002-WECC-2, Contingency Reserve, Request to Requirement R2 Drafting Team, and also by WECC in its roles as the Regional Entity responsible for assuring the reliability of the Western Interconnection and that of the Compliance Enforcement Authority..
Participants / Balancing Authorities and Reserve Sharing Groups subject to BAL-002-WECC-2.
Goal / To confirm there would be no adverseimpact on reliability within the Western Interconnection in the event that BAL-002-WECC-2, Contingency Reserve, Requirement R2 is retired.
Purpose and Premise / Preliminaryanalysis indicates that retirement of the requirement would have no negative impact on the Western Interconnection. The WECC-0115 drafting team is recommending retirement because: 1) the requirement may be operationally redundant once BAL-003-1, Frequency Response and Frequency Bias Setting goes into effect, 2) the combination of BAL-003-1 along with the BAL-002-WECC-2, Requirement R2 may be creating procurement of excess reserves thereby driving up costs without benefit, 3)procurement of the quantities and types of reserves specified in the requirement may not have any measureable positive impact on reliability, 4) proof of compliance with the requirement demands no empirical evidence, only a reporting that compliance occurred, and 5) reliance on the empirical evidence requirements of BAL-003-1 and BAL-002-1, Disturbance Control Performance are a superior measure of performance.
Start Time / The requested waiver would go into effect as of April 1, 2016, or as soon thereafter as permitted.
End Time / The requested waiver would cease no earlier than December 31, 2016 and no later than December 31, 2017.
Report and Review / The standard drafting team in coordination with WECC staff support will report any findings to the NERC Standing Standards Committee (SC) on the following schedule:
The initial report would be due to the SC on March 1, 2017 and on the first day of each subsequent quarter until the test and associated waiver cease.
A final report on the finding would be provided to the SC 90 days after completion of the test and waiver.
The project will not be balloted until the final report is presented for review to the appropriate WECC Ballot Pool and the NERC requirements of the NERC Rules of Procedure, 6.3 Communication and Coordination for All Types of Field Tests and Data Analyses has been met by NERC.
Data for Collection / Disturbance Control Standard (DCS) results, provided through the existing on-line WECC portals for receipt of these reports
Date Provided to: / WECC, Attention: Tim Reynolds.
Metric for Review / The data review and analysis will seek to determine whether retirement of the requirement would result in negative impact to the Interconnection. A key indicator would be whether there is a substantial degradation to the DCS recovery.
After-the-fact analysis could include, but not be limited to, review of: 1) comparison of data with and without the requirement, 2) DCS recovery, and 3) potential changes to the number of DCS violations, 4) recovery time in response of significant events, and 5) the amount and characteristic of reserves carried as reported by the responding entities.
The analysis would seek to cull out outlying events attributable to specific causes not relevant to the study.
