3 Background Energy Imbalance Market (EIM) The real-time market to manage transmission congestion and optimize energy imbalance (positive or negative) to balance supply and demand deviations for the EIM Area through economic bids submitted by EIM Participating Resource Scheduling Coordinators in the fifteen and five minute markets. 2

4 Background NV Energy Recap of Timetable NV Energy performs analyses and pursues Nevada regulatory approval to join the CAISO EIM in April, Public Service Commission of Nevada grants approval in Docket No on NV Energy performs stakeholder meetings and files OATT amendments with FERC in March 2015 targeting an October 1, 2015 market entry date. CAISO began EIM operations on 11/1/2014 with PacifiCorp as the first EIM Entity to join. FERC grants conditional approval to NV Energy on May 14,

5 Background Timetable continued FERC conditions include several future filings NV Energy must petition for authority to sell into its own BAA at market based rates (market power study). To be filed Friday, July 24. File any tariff changes for any solutions found pursuant to FERC s investigation of PacifiCorp s price excursions. Abide by market readiness criteria being developed and approved by FERC prior to any EIM entity joining the market. Within 15 months after go-live, file an informational report addressing whether sufficient data exists to alter the flexible ramping constraint allocation method. 4

6 Background EIM Terminology Review Market Operator - CAISO Operates the market model, produces dispatches EIM Entity BAA that has joined the EIM Participating Resource Resource that bid energy into the market Non-Participating Resources Resources within Balancing Areas not submitting bids Scheduling Coordinator Interfaces with Market Operator (EESC and PRSC) Data Schedules and forecasts System model Outages Dispatch instructions RTM: Real-Time Market FMM: Fifteen Minute Market RTD: Real-Time Dispatch RTUC (RTPD): Real-Time Pre-Dispatch 5

7 Background EIM Terminology Review EIM Transfer: Real-time energy dispatch instructions (1) NV Energy BAA and the CAISO BAA (2) NV Energy BAA and PacifiCorp east (3) CAISO BAA and PacifiCorp west Load Aggregation Point (LAP): A set of Pricing Nodes used for the settlement of demand in the EIM. NV Energy will use one LAP. Locational Marginal Price (LMP): The marginal cost ($/MWh) of serving the next increment of demand at a Pnode (price node). 6

11 Operational Overview Base Schedules Operating Hour Security Events 10

12 Operational Overview Base Schedules Transmission Customers provide a Preliminary base schedule Final base schedule serves as the financially binding starting point for the realtime energy imbalance market Transmission Customer Base Schedule (Attachment P, Section 4.2.4) An energy schedule that provides hourly forecasts for load, resource (generation), and interchange. NV Energy OATT, Attachment P, Section

13 Operational Overview Base Schedule - Preliminary Submission Transmission customers submit initial base schedules 7 days before the Operating Day. Method of Submission All generation resources in BA submit using the Base Scheduling Access Portal or BSAP. Loads Submit using means mutually agreed upon submission method with EIM scheduling coordinators. Excel template is provided on the OASIS website. Interchange Wheeling transactions are directed to provide 7 day interchange forecast data per the CAISO and NV Energy OATT. Generators selling outside the system will provide their generation forecast through BSAP and interchange submission through interchange tagging process. 12

14 Operational Overview Base Schedule Final Submission Final Submission in advance of the operating hour. Type Submission Method Initial Deadline Final Deadline NV Energy Generation Non-NV Energy Generation BSAP T-77 T-57 BSAP * T-77 T-57 Interchange e-tags T-77 Requested T-57 * If 100% of a non-nv Energy generator is under contract to NV Energy, the BSAP will be populated by the Resource Optimization group of NV energy. 13

18 Operational Overview Security Events and Outages Currently made public on OASIS Under EIM, outage forms will be completed in NV Energy s outage management system in real-time Outages will be posted on OASIS and communicated to CAISO within 30 minutes Outages will be reflected in market results for congestion, EIM dispatches, and settlements 17

19 Planned Outages and Derates Transmission, Participating & Non-participating units Notify EIM Entity at least 7 days in advance Preferably 30 days or sooner EIM Entity submits information to CAISO NV Energy OATT, Attachment P, Section 7 BPM Section 8 18

20 Unplanned Outages and Derates Transmission, Participating & Non-participating units Unplanned Outages As soon as practicable No later than 30 minutes after outage commences Unplanned Derates Report no later than 30 minutes after derate commences lasting longer than 15 minutes and availability is reduced by the greater of 10 MW or 5% of maximum plant output NV Energy OATT, Attachment P, Section 7 BPM Section 8 19

21 Questions 20

22 Settlements Overview Three settlement processes with the EIM 1) CAISO to EIM Participating Resources 2) CAISO to EIM Entity (BA) Settlement Load, nonparticipating resources and interties 3) BA settling with entities within their region 21
