Gas prices on the Southern parts of the California system have been exceptionally high in recent days due to the impact of cold winter conditions in other parts of the country. The Commitment Cost and Default Energy Bid Enhancements (CCDEBE) Phase 1 functionality provides suppliers an ability to update their fuel costs used in the calculation of commitment costs (start-up and minimum load costs) and default energy bids. Therefore, the ISO has expedited and completed the testing for its applications and systems to support CCDEBE Phase 1 functionality.

As such, the ISO is deploying the functionality of its CCDEBE Phase 1 initiative, effective for trade day Feb. 16, 2021. Specifically, the functionality will be available on the morning of Feb. 15 for the day-ahead market (DAM) so that it is effective for the real time trade day Feb. 16 at hour-ending 01:00 a.m.

 Market participants can learn more about changes to commitment costs and default energy bids in Attachment O of the Business Practice Manual (BPM) for Market Instruments available at https://bpmcm.caiso.com/Pages/BPMDetails.aspx?BPM=Market%20Instruments.

 All tariff language related to the CCDEBE Phase 1 initiative is effective for trade day Feb. 16. The tariff language provides detailed information on the following:

•  The Scheduling Interface and Business Rules (SIBR) application will allow market participants to submit Automated Reference Level Adjustments. Information on how to submit Automated Reference Level Requests is available in the SIBR User Guide at http://www.caiso.com/Documents/SIBRSchedulingCoordinatorUserGuide.pdf

• Within the Customer Inquiry Dispute and Information (CIDI) application, a button feature is available which allows market participants to submit manual reference level change requests. Information on how to submit a manual reference level change request is in the CIDI User Guide at http://www.caiso.com/Documents/NewCustomerInquiry_DisputeandInformation_CIDI_UserGuide.pdf

• A display in the ISO Market Results Interface (CMRI) application’s Default Commitment Cost report will now display default commitment bid values instead of proxy commitment cost values. More information on the values presented in this report is available in Section 10.1 of the BPM for Market Instruments.
