9 Day-Ahead Market Overview The Day-Ahead Market includes the Market Power Mitigation and Reliability Requirements Determination (MPM-RRD) process, the Integrated Forward Market (IFM) process, and the Residual Unit Commitment (RUC) process. The Day-Ahead Market opens seven days in advance of any Trade Day and is closed at 10am the day before the Trade Day. The Day-Ahead Market accepts Bids for Energy from Imports, Exports, Participating Demand, Non- Participating Demand and Generation. The Day-Ahead Market also accepts Bids for Ancillary Services and Residual Unit Commitment capacity. The settlement validation of Ancillary Services capacity products will be discussed in a separate module. Day Ahead Settlements may occur in the following processes: o The Integrated Forward Market will clear Bid-in Supply with Bid-in Demand, procure 100% of the Ancillary Service Requirement, and will produce financially binding Energy Schedules and Ancillary Service Awards. o The Residual Unit Commitment process will procure additional capacity as necessary to meet the forecasted Demand and may create settlements. o The Congestion Revenue Rights owners will have an hourly settlement based on the congestion prices produced by the Integrated Forward Market. o An Inter-SC Trade (IST) is a financial tool made available by the CAISO to help offset the potential double settlements associated with bilateral contracts. IST s for Energy will be settled using the LMP s from the IFM. Reference Document: See Market Operations BPM, Section 6 and the Settlements: Market Operations course for more details on how the Day-Ahead Market works. Customer Services Page 9 of 45

10 Settlement Review : Settlement files can be found in the Business Associate Portal Interface (BAPI). There will be two BA specific files for each trade day: Settlement Statement File in general, will show the total amount, by charge code, by settlement interval assessed to the BA. The level of detail show in the settlement statement varies by charge code. Billing Determinant File will show the individual billing determinants used to calculate the settlements for each charge code. For every charge code there is a BPM configuration guide that shows how each charge is calculated and the billing determinants used. Attachment E of the Billing and Settlements BPM shows a comprehensive list of all CAISO charge codes and links to each configuration file. This training used the BPM configuration guide exclusively to demonstrate these charge codes. When you see this symbol: Key Documentation: this will tell you from which configuration guide the formula was taken. Most of the time, the attributes have been left off the billing determinants in this training for clarity. The BPM will show you the entire billing determinant with all the attributes. Challenge of BPM Configuration Guide vs. BAPI statement: The Billing Determinant names in the BPM Configuration Guide are NOT the same as the name used in the BAPI statements. You will need to use the Billing Determinant Matrix to correlate the two documents. A link to the Billing Determinant matrix can also be found in Attachment E of the Billing and Settlement BPM.

13 Integrated Forward Market - Overview: What is it? The Integrated Forward Market is the work horse of the Day-Ahead Market. This is the process that uses the Bid pool created by the MPM process and clears Bid-in Supply with Bid-In Demand. As a result of the clearing process, Energy Schedules are created for both Supply and Demand. Ancillary Services are also procured in this process but covered in the Ancillary Service Workbook. Can I bid just for congestion? No, the Bid you submit will be for energy. If the CAISO has to re-dispatch the energy to solve for congestion, we will use the Energy Bids to determine how, and in what order to re-distribute the energy. Why would a resource receive this Charge Code (6011)? In general all resources that offer or schedule energy into the Day Ahead Market be it a Bid curve or a self schedule and are accepted in the Integrated Forward Market process will receive a settlement in Charge Code How would a resource receive a notification of a Day Ahead Energy Schedule? If a Bid or Schedule is submitted into the Market, the resource will receive a Day-Ahead Schedule report in CMRI (even if all the values are zero). If the resource receives an instruction, the report will have a non-zero value in the appropriate schedule report. What if my resource does not follow the Day-Ahead Schedule? The Day-Ahead Market will still settle as price x quantity. The Real Time charge codes will take into account deviations from the Day Ahead Schedule How do I validate my instructions?

Day Ahead Settlements does not take into account if the resource followed direction. Deviations from the Day Ahead Schedule are assessed in the Real-Time Market. Formula DA CC 6011 In simple terms: The Day Ahead Energy is broken down into 4 components: Day Ahead Energy Amounts not associated with an ETC/TOR/CVR schedule PLUS Day Ahead Energy Amounts associated with ETC/TOR/CVR schedules PLUS Congestion Credit for any ETC/TOR/CVR Schedule (Marginal Cost of Congestion at the contract node times the Schedule) PLUS Loss Credit for certain TOR Schedules (Marginal Cost of Losses at the contract node times the Schedule) = (-1) * [(DA Non-Contract Schedule) * DA LMP) + (Contract Self Schedule * DA LMP)] + (MCC * Contract Schedule) + (MCL * TOR Contract Schedule) Customer Services Page 15 of 45

26 Day-Ahead Energy - MSS: MSS with gross settlement election: Energy, congestion and losses will be treated the same as all other non-mss resources with respect to 6011 settlement. MSS with a net settlement election: CC 6011 will depend on if the net quantity in the MSS: is the MSS short or long. If the MSS is long (meaning excess supply) the net quantity will be paid the MSS price that is the weighted average of the generation in the MSS. If the MSS is short (meaning excess Demand) the net quantity will be charged the MSS Price which is based on the weighed average of the load nodes within the MSS Expected Energy Report: Most of the settlements pre-validation will have quantities shown in the Expected Energy Report within CMRI. This report is produced daily, the day after each trade day. Each Resource will have its instructions broken down to the type of instruction it receive. Reference Document: The Market Operations BPM, Attachment C, provides a comprehensive list of Expected Energy types. That Attachment will be used in conjunction with this training keep it handy. Intertie Tagging and the effects on Settlement tags: All Intertie schedules must have an e-tag in Real Time but that will not affect the Day Ahead Energy settlement. If an instruction does not have an e-tag, the financial ramifications will be accounted for in Real Time charge codes (CC6470), not Day Ahead 6011 Differences between places to validate instructions CMRI Day Ahead Market Results This report will be available after 1 pm every day.

The Market Power Mitigation process is the first process that is run in the Day Ahead Market. The purpose is to if a Unit is able to exercise market power due to where it resides on the network. This What does it mean to me? If your Unit is mitigated, the submitted bid may not match the Bid used in the integrated Forward market What charge code will I see the MPM settlement in? Technically you won t. That is to say, no direct settlement will occur in the MPM process. What does happen is if a Unit is mitigated, a mitigated bid curve will be used in the IFM. The unit will receive a schedule, based on the results of the Integrated Forward Market run and will paid the DA LMP. How would a resource know if it has been mitigated? A mitigated bid curve will be posted to CMRI in the Day-Ahead Market section under Market Power mitigation report. If the Unit was not mitigated, the report will be blank. What s the RRD portion mean? It is the Reliability Requirements Determination section. This is the process that determines if an RMR unit has a Day-Ahead Schedule that is considered an RMR Dispatch. Customer Services Page 27 of 45

28 MPM and Reliability Must Run Units: The MPM process has two different runs. The first run is called the Competitive Constraint Run (CCR). The program matches supply with forecasted Demand using a network model with only the competitive constraints activated. The next run is called the All Constraints Run (ACR). In this step, the program runs again to match supply with forecasted Demand the difference being all the constraints are turned on. If an RMR unit is increased between the CCR and the ACR run, the Unit will be under an RMR dispatch. MW up to the CCR level, are Hybrid. Unit will keep market payments and receive no additional contract payment. When ACR > CCR MW above CCR up to IFM, are Billable. Unit will be paid contract value and credit back market payments on RMR Invoice. In Real time, MW above the Day Ahead IFM schedule up to the CCR level are Hybrid. Unit will keep market payments and receive no additional contract payment. In Real Time, when RT ACR > RT CCR, MW from the RT CCR level up to the ADS Dispatch, are Billable. Unit will be paid the RMR Contract value and credit back market payments on RMR Invoice.

31 Section 3 CC 6800: Residual Unit Commitment Customer Services Page 31 of 45

32 Residual Unit Commitment (RUC): What is it? The Residual Unit Commitment is the last process in the Day Ahead Market. Since the Integrated Forward Market clears Bid-in Supply with Bid-in Demand, there may not be enough Supply scheduled to meet the forecasted Demand. The Residual Unit Commitment process is run to ensure there is enough available capacity to meet the forecasted Demand in Real-Time. What is the difference between RUC Award and RUC Capacity? Payment. Resources under Resource Adequacy (RA) contracts are required to bid into RUC but are not eligible for payment. Why would a resource receive this Charge Code (6800)? They received a RUC Award. (RUC capacity will NOT get paid). How would my resource receive instructions? If a Bid or Schedule change is accepted by the Market, the resource will receive a RUC award. This award will be found in CMRI as a RUC Schedule. In the Day-Ahead Market Residual Unit Commitment (RUC) Report, the award verses self is broken out. Award is eligible for payment, self is not. Will RUC show up in a Real-Time charge code? NO. RUC capacity will ensure the resource will submit a bid in the Real Time market. SIBR will do all the validation. Once the resource has a valid Real Time Bid, any association with RUC has been completed. How do I validate my instructions? Schedules: o CMRI: Generation or Import-Export Schedules o Day-Ahead Residual Unit Commitment (RUC) Capacity Customer Services Page 32 of 45
