Parameter name: stream1552-Comm-2252https://bpmcm.caiso.com/pages/viewprr.aspx?IsDlg=1&PRRID=1552<b>Description: </b>FAQs on 1552: Q. When is this PRR being implemented? A. After the PRR is approved and CAISO will communicate with the market participants in the MPPF and/or market notice. Q. When the CAISO will stop using day types in the histogram and mosaic methods other than 180 days of historical data? A. CAISO will communicate changes through the MPPF or MSC. Should a change be necessary from the communicated 180 days, then CAISO will submit a new PRR. Q. Is there a process the CAISO will follow when deciding whether to use something other than 180 days of historical data? A. The CAISO considers: o When a significant enhancement is identified, changes to FRP may occur after internal review and external communication. o The main metrics monitored for FRP performance are coverage and requirement. Coverage describes the fraction of intervals in which the FRP requirement was at or greater than realized uncertainty. Requirement is the average of requirement values over the period of analysis. The goal is to provide target coverage and where possible minimize average requirement. Currently, our review focuses on these two metrics. o The PRR change significantly enhances coverage metrics toward target across all BAAs. You can see the impact to BAAs in the following presentation deck https://www.caiso.com/Documents/BriefingonMosaicQuantileRegressionAnalysis-Feb2024.pdf. o The ISO continues to evaluate enhancements to performance metrics, especially those that will further highlight and account for reliability or awareness https://www.caiso.com/Documents/FlexibleRampingProduct-Presentation-Nov29_2023.pdf <br /><span style='font-size:11px;color:gray'> -By Martin, Michael on Friday, February 23, 2024 3:26:30 PM</span><br /><br />2024-02-23T15:26:30-08:001552-Recomm-1576https://bpmcm.caiso.com/pages/viewprr.aspx?IsDlg=1&PRRID=1552<b>Proposed Language: </b><div class="ExternalClassA7023EBEF3BF4A7091C7E1F06B494F21"><p>Approved as submitted.</p></div><br /><b>Apparent Requirement: </b>NA<br /><b>Priority: </b>NA<br /><b>Action: </b>Approve the BPM PRR as submitted<br /><b>Effective Date: </b><br /><b>Other Actions: </b>NA<br />2024-02-27T11:47:23-08:001552-FD-1499https://bpmcm.caiso.com/pages/viewprr.aspx?IsDlg=1&PRRID=1552<b>Final Decision: </b>Approve original<br /><b>Stakeholder Comment: </b>Answered questions on implementation, see Announcements<br /><b>Action: </b>Adopt the recommendation as originally issued<br /><b>Effective Date: </b>01/01/0001<br />2024-04-01T09:44:11-07:00
