Scenario 10 Scenario EIM Implementation - Nevada Energy and EIM Year 1 Enhancements – TD 8/11/15; Number Execution Time – 8/11/15 11:00 – 13:00 EIM Real Time – Contingency Event in the ISO Description BA ISO will simulate a contingency in the ISO BA via RT contingency. ISO will load our standard bid set, for non EIM entities we will create base schedules based on interchange data, and demand forecast. For EIM entities ISO will validate the schedules are balanced and feasible. ISO will run DAM and Real Time markets and publish results. Publish ISO Actions Settlements Statements. EIM resources receive dispatch instructions 10 EIM Market Participant Actions through ADS. 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 ISO Market Participant Actions OASIS. Contingency event in CAISO area does not Expected Outcome affect dispatches or prices in the EIM BAs. CC 64600, CC 64700, CC 67740, CC 69850, Anticipated Settlement Outcome and CC 64770 Page 8

Scenario 7 Scenario EIM Implementation - Nevada Energy and EIM Year 1 Enhancements – TD 8/11/15; Number Execution Time - 8/11/15 14:00 – 17:00 EIM Real Time – GHG Charges Description ISO to increase the Load Forecast for the ISO BA. EIM specific energy bids are cheaper than ISO Actions other imports to ISO BA. MP will provide GHG bid adder for selected participating resources in the EIM BAA. EIM Market Participant Actions Review Settlements Statements. 7 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. ISO Market Participant Actions GHG payments will be properly awarded to the exporting resources based on their export Expected Outcome allocation values.

Scenario 3 Scenario EIM Implementation - Nevada Energy and EIM Year 1 Enhancements – TD 8/12/15; Number Execution Time - 8/12/15 14:00 – 18:00 EIM Real Time – Flexible Ramping Sufficiency Description Test NVE/ISO ISO will load an ISO standard bid set; for non EIM entities ISO will create base schedules based on interchange data, and demand forecast. For EIM entities ISO will validate the schedules are balanced and feasible. ISO will set the Flex Ramp requirements (FRR) above available flex 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. ISO Actions Verify outcome Real Time results, Expected 3 EIM Market Participant Actions Energy and Settlements Statements. 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 ISO Market Participant Actions OASIS. NVE/ISO fails the flex ramp sufficiency test for some hours; NSI constraint will be binding leading to price separation between the EIM BAA and rest of EIM Area. Flex Ramp price will be set by penalty price in the EIM BAA. Flex Expected Outcome requirements will be available in OASIS. Anticipated Settlement Outcome CC 7050, CC 7024, and CC 7056 Page 12

Scenario 18 Scenario EIM Implementation - Nevada Energy and EIM Year 1 Enhancements – TD 8/13/15; Number Execution Time - 8/13/15 09:00 – 18:00 Description Joint ownership of resource in EIM BAA ISO to work with EIM Entities to identify joint ownership resources in the BAA. ISO to demonstrate new joint ownership resource ISO Actions dispatch functionality. EIM Market Participant Actions Validate dispatch instructions. 18 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. ISO Market Participant Actions ISO successfully dispatches the joint Expected Outcome ownership resource as per design. Anticipated Settlement Outcome CC 64600, CC 64700, and CC 4564 Page 13
