Market price correction for SCED. This notification is an update to the message sent at 11:48 AM on 09/02/2022. ERCOT has completed the analysis and has determined that a price correction is warranted under Protocol Section 6.3 for SCED Operating Day (OD) 09/01/2022. Due to a network issue, SCED failed to run for intervals 13:50 through 14:45. Protocol Section 6.5.9.2(2) states that for a SCED failure, RTM Prices will be set to the last good SCED run, prior to failure, for 15 minutes following restoration. During this timeframe, Real-Time Meter Prices (RTRMPRs) and Real-Time Settlement Point Prices (RTSPPs) were impacted for Settlement Intervals 15:00 and 15:15 . Once the system was restored, it was determined that a site failover was warranted until root cause analysis could be performed on the network failure. The site failover resulted in RTRMPRs being impacted for Settlement Intervals 17:45 and 18:00. The Price Correction will be finished by 16:00 on 9/6/2022. |
