Market price correction for SCED. ERCOT has identified a need to perform a price correction for Real-Time Settlement Interval 00:15 on Operating Day 8/23/2024. This was due to Emergency Basepoints being automatically activated during scheduled system maintenance. 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 08/27/2024. Since ERCOT does not post price corrections for RTRMPRs, this price correction will be reflected on the settlement statements of the impacted QSEs. |
