Market price correction for SCED. ERCOT has identified a need to perform a price correction for Real-Time Market Settlement Interval 16:00 on OD 05/09/2022 due to planned system maintenance. Only Real-Time Prices for Energy Metered for Resources (RTRMPRs) were impacted. There was no impact to Real-Time Settlement Point Prices. Corrections to the RTRMPRs will be finished by 16:00 on 05/11/2022. Since ERCOT does not post price corrections for RTRMPRs, this price correction will only be reflected on the settlement statements of the impacted QSEs. |
