Jul 9, 2022 8:57:59 AM Market price correction for SCED. This notification is an update to the message sent at 4:40 PM on 07/08/2022. ERCOT has completed the analysis and has determined that a price correction is warranted under Protocol Section 6.3 for SCED Operating Day (OD) 07/08/2022. The Real-Time On-Line Reliability Deployment Price Adder (RTORDPA) process incorrectly modeled their being up to 421 MW of deployed Load Resources other than Controllable Load Resources. This led to the RTORDPA being higher than it should have been during the impacted period, which is the SCED intervals from 1:35 PM through 4:30 PM. This corresponds to Settlement Intervals 1:45 PM through 4:45 PM. The RTORDPA was as high as $215.33/MWh during this time window. At this time, ERCOT has not identified any other impacted ODs. Completed price correction data will be posted on the ERCOT website as soon as possible, but no later than 4 PM on 07/12/2022, Tuesday. Alert Active

Jul 8, 2022 4:40:11 PM Notification of SCED prices under investigation. ERCOT is investigating the Real-Time Prices for SCED intervals starting at 13:35 on Operating Day 07/08/2022. This investigation is associated with a potential error in the Real-Time On-Line Deployment Price Adder process including deployed Load Resources other than Controllable Load Resources. This initial SCED interval corresponds to Settlement Interval 13:45. A follow-up notice will be sent out as soon as the investigation is complete. If a Real-Time price correction is needed for Operating Day 07/08/2022, the posting deadline is 16:00 on 07/12/2022, Tuesday. Alert Active
