10. IDT Reminders MPs are encouraged to exercise end-to-end Market processes –However, MPs are not required to bring Resources online solely for testing purposes. Echo Process: If a small MP or BA that represents Resources is unable to follow IM set-point instructions, but still able to disable ACE control then the IDT can still move forward if it is determined that reliability will not be adversely affected. These MPs will control their resources in manual mode. Importance of Control Status –If 1-2 Resources send the wrong control status, a mismatch will cause unnecessary discrepancies in solutions –Please remind your staff:  0: Resource is offline  1: Resources is online, dispatchable and able to provide contingency reserves  2: Resources is online, dispatchable and able to provide operating reserves (including Reg)  3: Resource is not dispatchable (coming online, going offline, test, or having issues that cannot follow dispatch) 10 For Reference Only

11. IDT Reminders EIS Market will continue to operate in parallel –LIPs will continue to be calculated normally based upon EIS Resource Offers –LIPs will be used for all Energy Settlement during IDTs –During IDTs, Unstructured Resource Deviation penalties will not apply in EIS Market Settlements Commit Resources as if the IDT was not occurring –MP should notify SPP that their Resource is coming online or offline and update the commit status in IM  For instance, self commit a resource coming on Submit Resource offers for use in RTBM to minimize mismatches –Resource offers should be consistent with operational parameters in EIS –Reg Ramp Rate curves and Contingency Reserve Ramp Rate curves should be set equal to the Ramp Rate Curve submitted for use in the Up direction in the EIS Market 11 For Reference Only

12. IDT Reminders COP populated using Resource and Ancillary Service Plans in the EIS –Resources should self commit in real time based on actual commitment –Resources identified in the EIS Ancillary Service Plans as providing Reg will be selected to provide Reg in the COP  MPs should submit a fixed amount for Reg-Up and Reg-Down with a zero Offer price so RTBM will allow clearing of Reg-Up and Reg-Down on the selected resources identified in the COP MP should set themselves to Fixed for Reserves (SPP will not do this for you) Operating Reserve Reqs set at the same level as those in the EIS Market –Reg-Up Dispatch Status: set to “Fixed” at specified MW –Reg-Down Dispatch Status: set to “Fixed” at specified MW – SPIN Dispatch Status: set to “Fixed” at specified MW –Online Supp: submit zero Supp Reserve Offer and zero price –Offline Supp: submit “Fixed” Offer at zero price –Not supplying ORs: submit reasonable offers based on actual current capability 12 For Reference Only

13. IDT Reminders Always follow IM Setpoints –Going into and coming out of IDTs, SPP wants MPs to be as close to EIS dispatches as possible RTBM Dispatch Instructions and cleared Operating Reserve will be sent to RTGEN system every 5 min –RTGEN will create Setpoint Instructions that will consist of the sum of the RTBM Dispatch Instruction, Reg Deployment and CRD –LMPs and MCPs will be generated for information purposes and will not be used for Settlement during IDTs Test Schedules should not be submitted during IDTs 13 For Reference Only

16. Preliminary Results 16 Scenario 7 Must Offer From initial analysis it appears that most MPs were short of their demand bids and were in emergency conditions that should trigger Must Offer penalties From here, it is a manual process for the Market Monitor to determine if they were actually short and send out all of the notifications For Reference Only

17. Preliminary Results 17 Scenario 28a Nonfunctional Testing: CMS Outage  CMS was disabled for about 15 or 20 minutes while the MPs continued to submit virtual transactions from the Markets User Interface.  When CMS was disabled, the credit check from Markets was disabled.  When the scenario was over, SPP brought CMS back online, and the DA Markets Desk approved the pending transactions and re-enabled the credit check from the Markets side. That triggered the auto-approve and re-synch process between Markets and CMS, and all processed successfully.  9 virtual transactions were pending credit approval for 6 asset owners. All 9 transactions approved with the operator manual approval action.  The manual notifications were sent successfully  There is a known defect with Enable Link button command. SPP believes this should be corrected with the next PRD release. For Reference Only

29. Tag Mirror/Replicate Process SPP is currently mirroring (copying) Production Tags from the EIS Market into the Integrated Marketplace Systems Process also modifies the tags to allow them to pass certain Marketplace Business Rules Copied tags are used to calculate the SPP CBA Net Scheduled Interchange (NSI) for use in the ACE equation Copied tags are used in RTBM to simulate activity from the current Balancing Authority activities 29 For Reference Only

30. Tag Mirror/Replicate Process Benefits The NSI calculated by the copied tags closely matches the aggregate 16 BA NSI for the current SPP EIS footprint Allows the SPP Engineers to study the Balancing Activities and compare those against the overall CBA NSI during the testing processes Important tool for Inadvertent verification purposes during deployment testing Lessened burden on MP not required to create tags 30 For Reference Only

31. Tag Mirror/Replicate Process - Costs Small number of MP have created test tags Tag Mirror Process renders Tariff validations invalid Test tags were approved regardless of tagging errors or failed evaluations necessary for CBA MP were trained on new Business Rules but have not been able to practice these new rules Errors and confusion for hundreds of tags for Go-live if MP do not begin the real tag submission process well in advance of Go-live 31 For Reference Only

32. Tag Mirror Process - Changes SPP will continue to Copy Tags for the first part of Parallel Operations –Tags Mirrored/copied – Nov. 12 thru Dec. 16 –Tag Mirror/copy will be turned off December 16 –Tag Mirror/copy will take days to wind down –Tag Mirror/Copy will not be reinstated for remainder of time to Go-live MP will enter tags January/February 2014 32 For Reference Only

33. IM Tagged Transaction entered by MP Import Tags into the SPP CBA (Required) –Consist of Load Serving Contractual obligations for SPP BA –Necessary for accurate NSI Export Tags out of the SPP CBA (Required) –Consist of Load Serving Contractual obligations for neighboring BA –Necessary for accurate NSI Internal SPP CBA tags (not allowed) Wheel/Through (not required/optional) 33 For Reference Only

34. IM Tagged Transactions - BP for approval SPP Operators will evaluate for new Business Practices: –Accurate Transmission Service –Accurate GCA and LCA for “SWPP” BA –Accurate Marketplace Protocols evaluation –Ramp Availability –Accurate Physical Path –Must include SWPP Transmission Service MP were previously trained on the new rules Operators will deny tags that do not pass 34 For Reference Only

35. IM Tagged Transaction Process – Getting Started MP will begin entering “Daily and Monthly” Import and Export tags for January Operating Month –Entry of tags between December 23 rd and December 31 –MP Will see evaluation failures to be remedied to gain approval –SPP Operators will assist MP/PSE with modifying tags for entry errors –When Tag is accurate SPP Operator will approve Optional - PSE adjust tags throughout January for Real Time Same process for month of February 35 For Reference Only

36. Impacts on Market Participants For the months of January and February MP will be required to “dual” enter. One tag in EIS Real time and an additional tag in IM Training Tag entered for Training will not need to be updated for real time. An average contractual mw profile will be adequate. Additional Tags are encouraged for Financial Market MP encouraged to compare EIS and IM settlement statements for strategy planning 36 For Reference Only

37. Impacts on Market Participants Required Tagged Transactions have been identified –Current EIS Tagged Transactions – 600 to 800 –Required Tagged Transactions – approximately 75 Impacted CPSE have been identified - CPSE involved in required transactions – approximately 12 CPSE are being contacted by SPP staff to communicate requirements for tag entry Tag entry also being coordinated with GP and LSE associated with required tags 37 For Reference Only
