18. Market Settlements Outstanding Questions • Question: Is there a way to automatically download (via API) the PDF Invoices from the Portal? • Answer: • The API only returns the XML Invoice. • Most systems that are using the API's are getting the results to load into a database and XML is format being used. • A PDF Invoice will be available and can be downloaded manually through the Portal UI (coming soon). Tony Alexander

19. Market Settlements Outstanding Questions • Question: Can SPP provide a list of Charge Types by MP type (Financial Only, Load Only, Resource Only, etc.)? • Answer: • Settlements Reference Toolsincludes 3 charge type documents. • Charge Type be Transaction Chartshows all charge types triggered by specific market activity (Loads, Resources, Virtuals, etc.) • Developing a report specific to this question. Tony Alexander

20. Market Settlements Progress • Initial Settlements for ODs 8-5 thru 8-15 are posted. • Initial Settlements for ODs 8-16 thru 8-17 are complete and being validated. • Final Settlements for ODs 8-5 thru 8-8 are posted. • Final Settlements for ODs 8-9 thru 8-10 are complete and being validated. • Weekly Invoice for 8-22 is posted. Tony Alexander

21. Settlement Issues • KIL#TBD: TCR to Settlements Transactions - Sell Indicator Logic Change • The interface between TCR/ARRs and Settlements sets the sign convention. • TCR Self-Convert quantities were being incorrectly reversed (error). • TCR Sell quantities were being correctly reversed (correct). • The fix has been implemented. • Initial Settlements for ODs Aug 14 forward will reflect correct data. • Final Settlements for ODs Aug 11 forward will reflect correct data. Tony Alexander

22. Settlements Scorecard Delay • Settlements Scorecard is still being developed and tested. • Targeting delivery next week. Tony Alexander

23. Settlements BSS and Meter Data Submission • CWG follow up. • Issue: Market Participants would prefer to use their own BSS and Meter Data submissions in Settlements. • The intent of the following slides is to raise awareness of the SMT settlement impacts. Tony Alexander

24. Settlements BSS Data Submission • The CWG has already decided that BSS metrics are not required for Market Trials. • MPs are not required to submit BSS data or participate in BSS testing. • Should BSS testing be removed from SMT scenarios? • SPP will continue to settle and report BSS activity based on MP participation. Tony Alexander

25. Settlements Meter Data Submission • Meter data is an input to over 50% of the charge types and over 80% of the scenarios. • Triggering charge types and scenarios requires the meter data to be; • less than set point, • more than set point, • or zero, • and must align to the same intervals as dispatch instructions. • Different variations are required to trigger desired charge types and scenarios. Tony Alexander

26. Settlements Meter Data Submission • Additional considerations: • If MAs are not submitting meter data according to set point there will be high amounts of deviation charges and credits. •  If MAs are not balancing Settlement Area generation, interchange, and load in their meter data submittals there will be high amounts of calibration. • Settlements needs to continue to run on OD+2 until the settlement systems are able to operate according to OD+4 timeline. • Meter Data submitted after OD+1 will be included on Final Settlements. Tony Alexander

27. Settlements Meter Data Submission • Below are some options to consider if MAs will be submitting their own meter data: • 1) Remove charge types and settlement scenarios from Market Trials metrics. • 2) Treat charge types and settlement scenarios as non-metrics, MPs will not hit them all (metrics are for reporting purposes only). • 3) Settlements can trigger as many charge types and scenarios as possible by Aug 31 and then begin using MA Meter Data only. • Open to other suggested options. Tony Alexander
