5. Tips and Guidelines 5  SMT Tips and Guidelines posted on spp.org SMT Tips and Guidelines  spp.org > Integrated Marketplace > Market Trials > Structured/Unstructured Test > Integrated Marketplace Market Trials Project Documentation Folder Information included: Mitigated Offers Even though we are not yet testing Mitigation functionality, SPP does still want MPs to submit mitigated offers. Resource Parameter Submission Guidelines Maximum Daily Energy, Maximum Run Time, Minimum Down Time, etc. Operating Reserve Fixed Dispatch MW Submissions MPs using the Fixed Dispatch Status for their OR Offers need to make sure the Fixed MW value they are submitting is reasonable

6. 0.1 Base Scenario – Day Ahead Weeks 3-4: Energy and Operating Reserves with Constraints 2.0 MP Activities Submit and/or update bids & offers no later than 1100 Day-Ahead (DA) All MPs: May submit a limited amount of virtual bids and offers MPs can only bid/offer up to 10 transactions for each hour The Credit Check for all Virtual Bid submissions will be bypassed for the start of Market Trials Fixed transactions, which will be populated from current production RTOSS, will be the only transactions considered (Weeks 1-4) 6

7. 4.0 – RTBM Outage Simulation 1.1 Scenario Description The RTBM application executes every 5 minutes to determine the dispatch setpoints and Cleared Reserves on each Resource using a Security Constrained Economic Dispatch. SPP has processes in place for different failure scenarios of the RTBM application. RTBM executing but unable to achieve a valid solution within a 5-min dispatch interval or Operator does not approve a case for a 5-min interval or RTBM application fails for less than 6 intervals RTBM executing but unable to achieve a valid solution within a 5-min dispatch interval or Operator does not approve a case for a 5-min interval or RTBM application fails for more than 6 intervals 7

8. 4.0 – RTBM Outage Simulation 8 1.2 Expected Results RTBM Application Not Executing or Loss Market System for < 6 Intervals (6/26/2013 from 11am to 12pm) MP does not receive Dispatch Instructions or Cleared Reserves for its Resource via XML for the intervals Resources still receive deployments for ICCP on a 4-second basis Energy Basepoints will be unchanged (stale) in ICCP RTBM Application Not Executing for > 6 Intervals (6/26/2013 from 1pm to 2pm) MP does not receive Dispatch Instructions or Cleared Reserves for its Resource for the intervals via XML RTGEN will begin deploying the system to follow load Energy Basepoints will change via ICCP The Total Dispatch Target and Dispatch Target Adjustment will be sent to the resource owner via ICCP The Total Dispatch Target is added to the current contingency reserve deployment and regulation deployment components to determine the setpoint for each resource, just as is done in the normal processing

9. 2.0 MP Activities Note that XML messages with Dispatch Instructions are no longer being received. Verify that ICCP deployments are still being received on a 4-second basis. Make sure appropriate RT Market Contacts receive notification from SPP of the interval that RTGEN will begin load following deployment and targets are not being determined by SCED. Verify that ICCP deployments are still being received on a 4-second basis. Make sure at least one unit is receiving instructions to move up or down, and that this unit has a non-zero Unit Dispatch Target Adjustment value. Make sure appropriate RT Market Contacts receive notification from SPP that they are returning to normal operations and dispatch targets as well as cleared Reserves will resume sourcing from RTBM 9 4.0 – RTBM Outage Simulation

10. 10 12.0 – Out of Merit Energy Dispatch (OOME) 1.1 Scenario Description SPP or a local transmission operator may issue reliability directives via a Manual Dispatch Instruction to any online Resource to resolve a reliability issue the market system cannot resolve (referred to as OOME) Time permitting, OOME dispatch directives will be issued by SPP. A Resource will receive Setpoint Instructions via ICCP (and XML as backup) from SPP that include a Manual Dispatch Instruction for the duration of the reliability directive or may receive a Manual Dispatch Instruction directly from a local transmission operator. The Manual Dispatch Instructions will specify the MW level the Resource is expected to produce until such time as the constraint can be resolved by SCED through the RTBM. While the OOME instruction is active, the resource minimum and maximum limits will be treated as though they are equal to the OOME instruction. The resource will not be eligible to clear reserve products during an OOME event. If MP does not have a resource online, this scenario will not be exercised with that MP.

11. 11 12.0 – Out of Merit Energy Dispatch (OOME) 1.2 Expected Result SPP Operators will issue the out of merit dispatch instruction via phone call to MP and receive a start and stop time. MP will receive the OOME instruction and OOME flag will be activated via ICCP and XML SPP Operators will remove the OOME instruction MP will no longer receive the OOME instruction and the OOME flag will be set to False via ICCP and XML as backup MP resource dispatch will go back to honoring the Real Time offer data 2.0 MP Activities MPs with Resources Offer resources as normal Observe OOME instruction and flag during OOME period *SPP will set up 15 min phone calls with each MP Market Trials Liaison with resources to issue and verify OOME activity. MT Liaisons should gather the staff who can make these verifications at their organizations for these calls.

12. 17.3 – Reserve Cap Testing 12 1.1 Scenario Description If a Resource fails all four compliance tests for a Operating Reserve product and the Resource’s individual smallest positive Shortfall Quantity is greater than 25% of the Contingency Reserve Deployment Instruction, a Reserve Cap MW is assigned to the subject resource. The amount of Contingency Reserve available to be cleared on Resource will be reduced by the lowest shortfall percentage based on the current Contingency Reserve Ramp Rate for online deployment, or Maximum Quick-Start Response Limit for Offline deployments, for the remainder of the Operating Day. 1.2 Expected Results Each resource that fails all 4 compliance tests by a shortfall of greater than 25% should receive a CAP MW. The online contingency reserve clearing of those resources should not exceed that CAP MW.

13. 17.3 – Reserve Cap Testing 13 2.0 MP Activities (Planned between 9am-12pm 6/27) Ensure that the resource identified by SPP is online in EIS Market. SPP sent out units to use via email on 6/19. The MP may choose another resource if the SPP selected resource is not available. If any changes occur, the MP will need to submit an RMS ticket no later than 6/26. (VERs not included in this test) Ensure the resource is registered as qualified for spinning reserves and on-line supplemental reserves. Ensure the OR Dispatch Status for Spin and/or Supp products are set to “Fixed” and MW amount greater than the scenario reserve cap (30MW). Ensure the resource’s Contingency Reserve ramp rate curves and operating range are large enough to exceed the reserve cap (30MW) Observe the clearing of Contingency Reserve on resources identified. SPP will watch for fixed CR clearing of the resource and apply the CR cap manually for a minimum of 6 intervals Scenario assumes resource “failed” to comply with a CRD event MP to observe resource compliance cap and that future clearing does not exceed the cap MW.

17. Unstructured Testing Tips 17 Types of Items MPs Should Test: DA Market Self commit during an operating day Self commit resources in the DA Market based on the MPs EIS resource plan (especially when settlements is available to see the interaction between DA Market and Real Time) Vary startup and no load costs on a resource to see the impact on clearing Submit virtual bids/offers at different pnodes Vary different commitment parameters and analyze results Max Daily Energy, Max Daily Starts, etc. Change Offers for Reserve Products Price Status

18. Unstructured Testing Tips 18 Types of Items MPs Should Test: RUC Vary different commitment parameters and analyze results Max Daily Energy, Max Daily Starts, Etc Change Commitment Status Reliability, Market, Outage, Self RT Market Integration with RTGEN startup and shutdown sequence – managing control mode 1. Control mode of 0 when offline 2. Control mode of 3 when ramping to min 3. Control mode of 1 or 2 when on and dispatchable 4. Reverse this when coming offline Change control modes for resources to see the effects on dispatch i.e. set control mode to 0 for a resource that is online, set control mode to 1 for a resource that is clearing regulation, etc.)

19. Unstructured Testing Tips 19 Types of Items MPs Should Test: Once CROW is integrated: Try to submit offers in the DA Market for resources that are outaged Once RTOSS is integrated: Enter in Dispatchable/Up to TUC transactions with very low prices to verify they clear if they are in the money Enter in Dispatchable/Up to TUC transactions with very high prices to verify they do not clear if they are out of the money Settlements: All kinds of changes and options Virtual bids vs. price –sensitive demand bid, URD, trigger other charge types
