Notification of Prices Under Investigation. On Operating Day (OD) 2/28/24 an issue occurred during routine maintenance which resulted in the Energy Management System sending incorrect constraint data for Generic Transmission Constraints to the Market Management System. Security-Constrained Economic Dispatch was impacted between 15:50 and 16:25. ERCOT is investigating the potential impact to Real-Time Market prices for this event. Given the complexity of the analysis, ERCOT will not be able to meet the deadline to correct prices before they become final at 16:00 on 3/1/24. Further analysis will need to be performed to determine if criteria is met for pursuing review by the ERCOT Board of Directors. A follow-up Market Notice will be issued once ERCOT has more information. |
