Flow Impact Due to Convergence Bidding for CRR Adjustment Report - Reports hourly MW flow contributions for transmission constraints impacted by SCs submitting Virtual Bids on behalf of a Convergence Bidding Entity that is also a CRR Holder. This report provides support information for CRR revenue adjustments applied the CRR Settlement Rule. Number 5 Short-Term Unit Commitment This section is based on CAISO Tariff Section 34.6, Short-Term Unit Commitment. At the top of each Trading Hour, immediately after the FMM and the RTUC for the same interval is completed, CAISO performs an approximately five-hour STUC run using SCUC and the CAISO Forecast of CAISO Demand to commit Medium Start Units and Short-Start Units with Start-Up Times greater than the Time Horizon covered by the FMM. The Time Horizon (see Exhibit 7-1) for the STUC optimization run extends three hours beyond the Trading Hour for which the FMM optimization was run, and replicates the Bids used in that Trading Hour for these additional hours. CAISO replicates Bids each time the hourly STUC is run by utilizing: (1) bids previously submitted in RTM by Scheduling Coordinator for that Trading Hour; or (2) the clean bid from the DAM if the resource has a Day-Ahead schedule or received a start-up instruction in RUC for the trading hour, or if the resource has a Real-Time must offer obligation for that trading hour. A Start-Up Instruction produced by STUC is considered binding if the resource could not achieve the target Start-Up Time (as determined in the current STUC run) in a subsequent RTUC run as a result of the Start-Up Time of the resource. A Start-Up Instruction produced by STUC is considered advisory if it is not binding, i.e., when the resource can achieve its target Start-Up Time (as determined in the current STUC run) in a subsequent RTUC run based on its Start-Up Time.
