NEW STRUCTURED SCENARIO • Supply Adequacy/EI Constraint • Scheduled for 11/12/2020 (New Date) • This presentation is posted here: • https: //spp. org/spp-documents-filings/? id=235151 • Scenario Goals • EI Constraints: When BA is short, market will enable EI constraint(s) impacting WRTBM prices • MP Supply Insufficiency Check: All MPs required to short their Supply Adequacy for the day, then update their resource plans to firm up their supply 4
SA/EI CONSTRAINT SCENARIO DETAILS PRIOR TO OP DAY 11/12/2020 • Check the results of Day-Ahead Supply Adequacy on 11/11/2020 • Available by 11 am CST, day before target Op Day • Use for reference only • For Op Hours Beginning 0800 -1700 of 11/12/2020 • Each MP will intentionally SHORT your supply • Using combination of Resource Plans, Fixed Op Reserves and energy tags 5
SA/EI SCENARIO DETAILS (CONT. ) ON OP DAY 11/12/2020 • Check the results of Next-Hour Supply Adequacy • Ensure hours before 1400 remain short • For Op Hours Beginning 1400 -1700 of 11/12/2020 • Each MP will FIRM up your supply • Using combination of updated Resource Plans, Fixed Op Reserves and energy tags • Goal: During the Op Hours a BA is short, the WRTBM prices will be impacted by an activated EI constraint 6
KEY POINTS • MPs must ensure their Supply Adequacy is short between 0800 -1400 of 11/12/2020 • Tips: Remove tags, add exports, reduce resource and OR availability, limits, etc. • SPP will confirm EI constraints are activated and impacting prices appropriately • Prior to 1400, MPs must firm up their supply for 14001700 such that their supply is reported as adequate • This can be done ahead of time as necessary. • SPP will confirm that BAs are whole and EI constraints are no longer activated* *SPP may make manual adjustments to ensure the scenario is successful 7
