7. Day Ahead SCUC vs SCED Difference (Follow Up) • SPP preliminary results on analyzing the SCUC/SCED differences have found the following factors having significant impact: • Violation Penalties • SCUC: values set high enough to encourage the natural economics of the system to commit appropriately around the formulation constraints • SCED: values set high enough to encourage the natural economics of the system to dispatch appropriately around the formulation constraints • Challenge: violation penalties must be higher for commitment than for dispatch. But how high? • SPP proposal: adjust the values of selected SCUC violation penalties so as to minimize relative economic differences between SCUC and SCED • Transmission violation penalty • Status: results are encouraging Bart Tsala

8. Day Ahead SCUC vs SCED Difference (Follow Up) • Transmission Violation Penalty (sample Operating Day) • Case A: SCUC Transmission Penalty @ $/MW 150,000 • System transmission breach ~ 172 MW • Resource X: committed by SCUC. SCED total Energy dispatch ~ 360 MW • Effective impact on transmission breach ~ 1 MW • Out of Merit Margin to provide transmission relief ~ $ 16,000 • Case B: SCUC Transmission Penalty @ $/MW 30,000 • System transmission breach ~ 176 MW • Resource X: not committed by SCUC. SCED total Energy dispatch ~ 0 MW • Effective impact on transmission breach ~ 0 MW • Out of Merit Margin to provide transmission relief ~ $ 0 • System resource ramp violation: increases by ~ 40 MW (no free lunch!) Bart Tsala

9. Day Ahead SCUC vs SCED Difference (Follow Up) • SPP preliminary results on analyzing the SCUC/SCED differences have found the following factors having significant impact (continued): • Ramp Rate Models • SCUC: effective ramp rates computed over the dispatch range of the resource as seen between its defined min/max MW values. Fully time coupled commitment valuation • SCED: effective ramp rates computed over the dispatch range as seen from the previous time interval dispatch level. Partially time coupled dispatch valuation • Challenge: resource DA SCED 24-hr dispatch schedule could divert from SCUC as it: • Potentially uses a different effective ramp rate for each hour • Does not anticipate future energy ramp adjustment needs • SPP Proposal: allow for DA SCED to use the same effective ramp rate as SCUC • Status: results are encouraging Bart Tsala

10. Day Ahead SCUC vs SCED Difference (Follow Up) • Planned Software changes: • Violation Penalties • No software update required. • Ramp Rate Models • Release 1.7 provides an option for DA SCED to use the same effective ramp rate as SCUC. • In 1.7 release testing the enabling of this option has had a positive effect on price spikes. Bart Tsala

11. Preliminary Results from Oct 14 - 18 • Scheduled Scenarios • 28b – Non-Functional Testing: RTBM Outage • 28c – Non-Functional Testing: Markets UI/API Outage during DA Submission • 28d – Non-Functional Testing: Markets UI/API Outage during DA Results • 28e – Non-Functional Testing: Single Site Outage • Questions? Alan Adams

13. Meter Data (Correction) • Meter Data submitted for September 26 Operating Date was 30% Tony Alexander

14. Market Settlement System (MSS) Known Issues • KIL# 745 We have identified an issue in a handful of the settlement statements where the settlement engine is calculating the full amount on final settlement (or resettlement) instead of the incremental (or net) amount. • Net difference between Initial, Final, and Resettlement is incorrect. • 8/11/13 F, 9/4/13 F, 9/5/13 F, 9/5/13 R2, 9/9/13 F, 9/16/13 F, 9/20/13 F, 9/27/13 F • There is no work around for this issue. • This is expected to be fixed in November. Tony Alexander

15. Settlements Charge Type Scorecard • The Settlements Charge Type Scorecard for the week of October 18 is posted. • Includes Operating Days September 30 through October 6. Tony Alexander

16. Settlements Charge Type Scorecard Tony Alexander

17. Settlements Charge Type Scorecard Tony Alexander

18. Charge Types Not Using Stubbed Data • All Charge Types are using upstream data from September 25 Operating Date forward. • 43 Charge Types or 100% of the Charge Types for SMT. • MPs should validate these Charge Types “Bid to Bill”. Tony Alexander

19. Charge types not using stubbed data • MPs should validate these Charge Types “Bid to Bill”. Tony Alexander

20. Charge Types Not Included In SMT • ARR/TCR Annual Charge Types • ArrPaybackYrlyAmt, ArrCloseoutYrlyAmt, TcrPaybackYrlyAmt, TcrCloseoutYrlyAmt • Demand Response Load Charge Types • DaDrHrlyAmt, DaDrDistHrlyAmt, RtDr5minAmt, RtDrDistHrlyAmt • Other Various Charge Types • MiscDlyAmt, RtJoaHrlyAmt, RtRsg5minAmt • MCRRs/MPRR New Charge Types Tony Alexander

21. Announcements & Outstanding Questions • Scenario 24 – LMP Re-pricing rescheduled for October 22 • Financial Only MPs: :  Please plan to test scenario #3a and #3, entering virtual offers using credit, on October 29, 30 as scheduled.  • SPP expects every MP (including FINANCIAL-ONLY MPs) to participate in these Scenarios • Please review the Scenario 3 documents on spp.org here: spp.org > Integrated Marketplace > Market Trials > Structured/Unstructured Test > Integrated Marketplace Market Trials Project Documentation Folder > Structured Market Trials Scenarios Ginny Watson

22. Disabling webMirror • SPP has the option to disable webMirror for individual Creating PSEs if they choose. • Submit an RMS ticket to start the process. SPP will respond within 1 week. • MP should begin dual entry of tags to both EIS production tagging and the Market Trials tagging environment once webMirror is disabled. • Be aware that turning webMirror back on will not catch-up transactions. webMirror is triggered upon tag creation. Wendy Reynolds

23. Look-Ahead: Oct 21 – Oct 27 • Oct 21 – Oct 27 Daily Calendar • spp.org > Integrated Marketplace > Market Trials > Structured/Unstructured Test > Integrated Marketplace Market Trials Project Documentation Folder • Includes some Settlements Dates. All details on Settlements Calendarmarketplace.spp.org > Public > Settlements > Calendars • The week of Oct 28, a new Daily Calendar with a “Parallel Ops Look Ahead” will be posted here: • spp.org > Integrated Marketplace > Market Trials > Parallel Operations Test > Integrated Marketplace Parallel Operations Project Documents • This Daily Calendar will supplement the Parallel Ops Monthly Calendar • Scheduled Scenarios • 24.0 LMP Repricing • 6 Unstructured Test Days • Official Operating Days Monday – Friday • Starting Sun Oct 20: Official ODs 7 Days / Week • Friday Maintenance & Saturday reserved for MP Testing Ginny Watson

24. 24.0 Re-pricing Scenario Description • Due to input data issues, systems failures, or other reasons, SPP will sometimes need to re-price some periods of the RTBM • Any potential need for re-pricing will be noted by the RTBM operator each night • Cases will be further analyzed and re-pricing either rejected or passed along to the Operations Engineers to execute the re-pricing process • SPP will make appropriate adjustments to RTBM input data for the period that needs to be re-priced, re-execute the offline version of the RTBM and pass the results to Settlements as substitute LMPs with the Losses and Congestion components as well as the Market Clearing Price of the Reserves Alan Adams

25. 24.0 Re-pricing Expected Result • SPP re-prices a period of the RTBM • MPs see the substitute LMPs (including all three components) as well as MCPs for Reserves via the Marketplace Portal. • MPs will receive an email notifying them of the re-price. • The email will contain market type, date/time of intervals re-priced, and a link to the Marketplace Portal. SLMP data will be found in the Public tab of the Marketplace portal. • Re-priced csv’s will be noted with an R1 at end of case name • SPP processes the Settlement Statements with the substitute LMPs and MCPs for that period. The MPs will not see this part of the test. Settlement statements will not differ whether an interval has been re-priced. Alan Adams

26. 24.0 Re-pricing MP Activities • Same as the RTBM Base Scenario Alan Adams
