1 2016 SOL Methodology Revision Stakeholder Update November 29, 2016 Vic Howell Manager, Operations Engineering Support

2 Webinar Objectives Recap accomplishments to date Provide a high level overview of draft SOL Methodology 8.0 posted on 11/23 for stakeholder review Review key changes Review revised project timeline Understand how to provide comments Discuss training plan

3 THANK YOU, Small Team!! TOP Arizona Public Service Company Bonneville Power Administration British Columbia Hydro & Power Authority California Independent System Operator Los Angeles Department of Water and Power PacifiCorp Public Service Company of Colorado Public Utility District No. 2 of Grant County, Washington Sacramento Municipal Utility District Salt River Project Agricultural Improvement and Power District San Diego Gas & Electric Tri-State Generation and Transmission Tucson Electric Power Western Area Power Administration - Rocky Mountain Region SmartWires Name Luis Leon Daniel Kuraspediani Guihua Wang Dede Subakti Vin Vongvaravipatr William Ruthruff Robert Johnson Ken Che Wei Shao Jose Silva Anita Hoyos Igor Kormaz Eric Raatz Yishan Li Chifong Thomas

4 Recap Three main objectives with revision: o Incorporate NERC SOL White Paper Concepts o Implement POTF recommendation o Align with the concepts and principles in the new TOP/IRO Reliability Standards Conceptual Modifications to the SOL Methodology document sent to stakeholders on 7/29

5 Recap (continued) Posted doc on 9/3/2016 for stakeholder review DRAFT SOL Methodology Revision First Informational Release TOPs instructed to go ahead and begin preparing for these changes Contains sections of the future revised SOL Methodology: o o o o General changes (POTF Recommendation, alignment with NERC SOL Whitepaper and new TOP/IRO standards) Multiple Contingencies in operations Allowed uses of load-shed and non-load-shed schemes System stressing methodology (WECC OC-approved doc from POITF)

6 DRAFT Revised SOL Methodology Posted DRAFT SOL Methodology version 8.0 on 11/23/2016 for stakeholder comment Sections added to the first informational release o Coordination Responsibilities o SOLs Used in the Operations Horizon Facility Ratings, System Voltage Limits, Stability Limitations o Instability, Cascading, uncontrolled separation, and IROLs

7 DRAFT Revised SOL Methodology (continued) IROL Establishment IROL T V in the Peak RC Area IROLs established by the PC and TP consistent with the PC s SOL Methodology for the planning horizon Other items retained from current version 7.1

8 Key Changes Facility Ratings Facility Ratings used in Operations Horizon determined by TOP More specifics on which Facility Ratings Peak will use Facility Ratings < 15 min used only for extenuating circumstances and when verified and acceptable by TOP and RC Requirements for TOPs that use dynamic Facility Ratings

9 Key Changes System Voltage Limits System Voltage Limits used in Operations Horizon determined by TOP Specifies where System Voltage Limits need to exist Requires normal & emergency high & low limits Specific requirements for certain System Voltage Limits Contains a mechanism to ensure TOP submitted System Voltage Limits provide for reliable operations

10 Key Changes Stability Limitations Acceptable methods: o Use real-time tools to assess instability o Use predetermined stability limit values Transient and post-transient analysis methodology o Baseline requirements to facilitate consistency Transient performance requirements table

11 Key Changes IROLs 1000 MW threshold goes away Description of instability, Cascading, and uncontrolled separation for IROL establishment Distinguishes an IROL from a condition o An IROL is a limit not a condition o IROLs are identified one or more days prior to real-time; however, the IROL value can be calculated in real-time o Unanticipated N-1 and credible N-2 insecure states that may occur in real-time operations are addressed outside of IROLs but, like IROLs, they must be mitigated within 30 minutes

12 Key Changes IROLs (continued) Distinguishes between long-term IROLs and planned outage condition IROLs Long-term IROLs applicable for: o Single P1 Contingencies o Credible Multiple Contingencies o N-1-1 and N-1-2 operations starting with an all lines in service case(s) Planned outage condition IROLs applicable for: o Single P1 Contingencies o Credible Multiple Contingencies

13 Key Changes IROLs (continued) Process for identifying planned outage condition IROLs Description, application, purpose, and rationale for N-1-1 and N-1-2 IROLs Detailed process for identifying N-1-1 and N-1-2 IROLs, examples provided IROLs and Risk Management for Localized, Contained Instability Impacts Process for determining acceptable levels of risk for IROL determination

14 Key Changes IROLs (continued) Transient stability IROLs Voltage Stability IROLs Facility Rating-Based IROLs, example provided Short IROL T V section How Peak addresses IROLs identified by PCs and TPs

15 Other Issues TOPs are expected to continue with the RC Seasonal SOL Coordination Process until a replacement process is developed and implemented Some RC Instructions are noted as currently under development Guideline for Establishing System Voltage Limits currently under development Peak developing contingency plans if FERC doesn t agree to retire TOP-007-WECC-1a

16 Project Timeline DRAFT SOL Methodology posted for TOP stakeholder comment 11/23/2016 TOP stakeholder comments due 12/16/2016 (~3 weeks) Peak to publish final revised SOL Methodology 1/13/2017 April 1, 2017 SOL Methodology effective date

17 TOP Stakeholder Comments Comments from TOP stakeholders only Comments provided via Peakrc.com website only do not send red-lines or marked up versions with Microsoft Word comments added Please indicate the name of the TOP represented Peak will respond to all comments Link to comment area on right-hand side of Peakrc.com main page under Comments Invited section
