3. IDT Schedule and Conditions page 1 of 2 3 Ginny Watson IDT DateIDT TimeConditionNotes Various IDTs Follow Resource Online If you have a Resource already planning on coming online during a regularly scheduled IDT, please let us know via RMS.RMS 1/7/143:30P-1:30A 8hr IDT begins at 4:30P, crosses midnight *changed from 2:30P – 12:30A (IDT at 3:30P) Crosses Midnight Regulation Pre- Selection / Co- Optimize Regulation SPP will exercise Regulation pre-selection during the 01/07 IDT. This will run through normal ID-RUC regulation pre-selection, allow BA Operators to change Resources from certain regulation, etc. 1/9/148:30A-12:30P 2hr IDT begins at 9:30A ICCP Failover SPP has requested that an MP perform an ICCP failover in the middle of the January 9th IDT. This was a request from the CWG for a real world condition. SPP will coordinate with individual MP.

4. IDT Schedule and Conditions page 2 of 2 4 IDT DateIDT TimesConditionsNotes 1/10/146:30A-4:30P 8hr IDT begins at 7:30A *changed from 5:30A – 3:30P (IDT at 6:30A) Simple Failover Failover will be a standard model upload failover and primary systems will not be down for but a few minutes. The secondary system will be up and providing setpoints along with the XML signals. Loss of ICCP Disable all outbound data from both the primary and secondary ICCP systems creating a complete loss of all setpoints for all MPs for 15-30 min. MPs will follow XML instructions. SPP BA Operators exercise procedures for selecting and communicating Reg movement to resources. The loss of ICCP data will only be simulated from SPP to members. 1/21/144:30P-8:30P 2hr IDT begins at 5:30P Tieline Drop SPP loses select tie-line measurements. SPP will simulate the loss of real-time data with significant tie- line data providers. MPs will not need to take any action; this is an internal process for our operators. SPP will lose generator real-time and tie-line data EDR Testing with specific MPs will occur during this IDT 1/27/144:30P-10:30P 4hr IDT begins at 5:30P Ginny Watson

9. Regulation Selection Condition Currently during Integrated Deployment Tests (IDTs) MPs are bidding in their Regulation as Fixed for Resources carrying Regulation in EIS In order to fully test the Regulation selection processes, SPP would like to run an IDT with MPs offering in Regulation as they would in Production This allows SPP and MPs to test the processes and procedures surrounding the clearing and selection of Regulation during the IDT timeframe This will also allow the RTBM clearing engine to clear Regulation based on economics including impacts to constraints 9 Casey Cathey

10. Regulation Selection Condition Planned to occur during the IDT scheduled for 1/7/2014 MPs with Regulation qualified Resources will offer Up and Down Regulation to the market with appropriate prices – It is vitally important that MPs submit correct Eco limits and Regulation limits to fully exercise this condition SPP will exercise the normal Regulation selection process to select all Resources that will be eligible to clear Regulation in RTBM each hour and as necessary RTBM will then clear Regulation based upon the Offers submitted by participants and RTGEN will deploy based on these cleared Resources 10 Casey Cathey

15. Deltas from first 4 IDTs During the IDT SPP utilized offsets to account for Resources not following dispatch at the beginning of the test – Biasing the load with offsets requires more energy to be dispatched moving Resources into more expensive bands or less expensive bands depending on the direction of the offset There was a large difference on Dec 3 at 6:55 – SPP approved offset case of 80 MW Base case max LMP = $165 80 MW offset case max LMP = $850 – 150 MW offset case would have raised max LMP to $1,200 15 Casey Cathey

17. 12-15-13 Deployment Test Debrief Overall the Seventh Deployment test was another success –BAs and MPs were on the call 60 min before IDT began. Thank you!  Only 1 MP was missing –Ramp Sharing will be on for all three of the IDTs during the week of Dec 15 –Smooth transition into test; best entry to date  ACE under control; SPP well within L10  Successful entry attributed to EIS and IM Resource Plans matching up well –Resource trip managed without calling a CRD event due to the high ACE prior to the trip  Immediate recovery with Regulation; process worked properly –No big issues; overall, test managed and controlled well 17 For Reference Only

18. 12-15-13 Deployment Test Debrief Though a “Success” - areas of concern/opportunities to improve –Start of test was delayed 1 hour due to one BA having issues with ICCP  SPP delayed IDT start to ensure entry into test was smooth and stable  Official 3 hour IDT 1:30P – 4:30P  Official NERC Waiver Period 1:15P – 4:45P –2 CPS2 Violations  Following the initial smooth transition into the test – experienced a high positive ACE for 40 minutes  Not enough Ramp capability available  Units on Reg that couldn’t perform as offered in  SPP worked directly with a number of MPs who were off dispatch to remedy  SPP finally able to cross ACE and the remainder of the test went smoothly –SPP followed up with MPs as normal business issues occurred  CMODES  Failed individual setpoints 18 For Reference Only

19. 12-15-13 Deployment Test Debrief REMINDERS: –webMirroring off December 16 –IDT Call starts at 2:30A on December 17 19 For Reference Only

20. Set Points Details on the different set points that SPP provides via ICCP Target Base Point = 5 minute stepped energy only Set Point (4 second signal) = Stepped energy and deployed Operating Reserves Ramped Set Point (4 second signal) = Ramped Energy + Deployed Operating Reserves achievable but reset every 5 minutes 20 For Reference Only

22. 12-17-13 Deployment Test Debrief Overall the Eighth Deployment test was a great success! –All BAs and a majority of MPs were on the call 60 min before IDT. Thank you!  7 MPs missing –Ramp Sharing on for all three of the IDTs during the week of Dec 15 –Smooth transition into test; another successful entry  ACE under control; SPP well within L 10 –Resource came online during the 0400 hour; everything worked well –Overall, MPs did a better job following IM setpoints –Test managed and controlled well 22 For Reference Only

23. 12-17-13 Deployment Test Debrief Though a “Success” - areas of concern/opportunities to improve –1 CPS2 Violation  Following the smooth transition ACE dipped at the top of the 0400 hour due to: – SPP ramping in a lot of schedules ~700 MW NSI change » Ramp Reservation System is not limiting schedule changing; this will be different in Production – Wind Generation was dropping – Steep Load Growth  Recovered quickly and came out of the interval in good shape – The entire remainder of 4 hour IDT went well –SPP continues to work directly with MPs who are off dispatch 23 For Reference Only

24. 12-17-13 Deployment Test Debrief IDT Conditions – webMirroring off as of December 16 –Please make a better effort to get schedules in –SPP is handling through NSI offset  MPs need to get schedules in so SPP doesn’t have to put in an offset and can test OATI system 24 For Reference Only

25. IDT Reminders 12/19 IDT Call starts at 5:30 AM, 2 hour IDT begins at 6:30 AM –Pseudo Tied In Resources  An MP requested permission to test a Pseudo-Tied in Resource during the 12/19 deployment test. SPP had asked the MP not to include the Resource in deployment testing before 12/19 due to the pseudo-tied issue. –RSG Event  First IDT with all RSG changes effective –Follow Resource Online  Please remember to coordinate with SPP if you have a Resource coming online during an IDT  An MP brought a large unit on during today’s test but did not coordinate with SPP operators – SPP was able to manage ACE but coordination woul dmake the process much easier.
