1. Introduction The objective of this document is to provide the information needed for ISO MPs and EIM entities to participate in the structured market simulation scenarios for the Flexible Ramping Product initiative. 2. Structured Scenario Approach 2.1 High Level Overview These identified scenarios will be executed during the structured scenario portion of the Fall 2016 Release Phase 2 market simulation. 2.2 Structured Scenarios Conditions and Setup The following additional setup will be used by the ISO during the scenario execution. 1. All EIM Entity s will need to balance during the timeframes identified in the scenarios Execution Time. 2. ISO MPs and EIM Entity s will need to submit/overwrite the ISO seeded bids if desired.

2.3 Structured Scenarios Scenario Number Flexible Ramping Product Implementation TD 8/31/16 10:00-12:00 1 Description ISO EIM Market ISO Market Expected Anticipated Settlement BAA fails Flex ramp sufficiency test upward direction For EIM entities ISO will validate the schedules are balanced and feasible. ISO will set the Flex Ramp requirements (FRR) greater than available flex ramp up capability in the EIM BAA. Broadcast the ISO, EIM BAA, and EIM footprint total load forecast, broadcast the FRR for the ISO, EIM BAAs, and EIM footprint to the Market. Perform flexible ramping requirement sufficiency test. T-75, T-55, T-40. Review EIM GHG Shadow Prices, EIM Transfer Limits, EIM Transfer MW s, EIM Transfer Net MW, EIM Transfer Shadow Price, EIM Transfer Schedule Shadow Prices, EIM Entity Demand Forecast, EIM BAA NSI and EIM LMP s on OASIS. Import is curtailed to the lesser of the FMM a) net EIM transfer import at T-7.5 or b) the base import transfer of the prior hour. Requirements will not reflect the EIM diversity benefit, but will include any FRU credit (for EIM export deviations above the net imbalance energy export for trading hour). Failed BAA will not be included in the Flex Ramp BAA constraint, but will be included in the EIM Area BAA constraint (relevant with FRMP breakdown). Daily Statement: CC 7070, CC 7071, CC 7076, and CC 7077. Release Planning Page 5 of 9
Scenario Number Flexible Ramping Product Implementation TD 8/31/16 13:00-16:00 2 Description ISO EIM Market ISO Market Expected Anticipated Settlement BAA fails Flex ramp sufficiency test downward direction For EIM entities ISO will validate the schedules are balanced and feasible. ISO will set the Flex Ramp requirements (FRR) greater than available flex down ramp capability in the EIM BAA. Broadcast the ISO, EIM BAA, and EIM footprint total load forecast, broadcast the FRR for the ISO, EIM BAAs, and EIM footprint to the Market. Perform flexible ramping requirement sufficiency test. T-75, T-55, T-40. Review EIM GHG Shadow Prices, EIM Transfer Limits, EIM Transfer MW s, EIM Transfer Net MW, EIM Transfer Shadow Price, EIM Transfer Schedule Shadow Prices, EIM Entity Demand Forecast, EIM BAA NSI and EIM LMP s on OASIS. Export is curtailed to the lesser of the FMM a) net EIM transfer export at T-7.5 and b) the base export transfer of the prior hour. Requirements will not reflect the EIM diversity benefit, but will include any FRD credit (for EIM import deviations below the net imbalance energy import for trading hour). Failed BAA will not be included in the Flex Ramp BAA constraint, but will be included in the EIM Area BAA constraint (relevant with FRMP breakdown).

Scenario Number Flexible Ramping Product Implementation TD 9/1/16 10:00 12:00 Description Flex Ramp Infeasibility Up 3 ISO Market ISO Market Expected Anticipated Settlement ISO will set the requirements high to drive into infeasibility for flex ramp. The flex ramp up price will be set according to the demand curve depending on the infeasibility MW. CC 7070, CC 7071, CC 7076, CC 7077, CC 7081, and CC 7087 Monthly Statement: CC 7078* *Will be included in the TD 9/1/16-9/2/16 mini-monthly. Release Planning Page 7 of 9
