Market price correction for SCED. ERCOT has identified a need to perform a price correction for Real-Time Settlement Interval 06:00 on Operating Day 8/08/2023. This was due to Emergency Basepoints being automatically activated when SCED interval 05:45 failed to run. ERCOT has determined that the impact to Real-Time Meter Prices (RTRMPRs) meets criteria for price correction in accordance with ERCOT Protocol Section 6.3(5). Corrections to RTRMPRs will be finished by 16:00 on 08/10/2023. Since ERCOT does not post price corrections for RTRMPRs, this price correction will be reflected on the settlement statements of the impacted QSEs. |
