NOTICE DATE: November 5, 2022
NOTICE TYPE: M-A110522-01
SHORT DESCRIPTION: Issue identified with the Day-Ahead Market (DAM) Operating Day (OD) 11/6/2022 Ancillary Service (AS) Awards
INTENDED AUDIENCE: ERCOT QSEs
DAYS AFFECTED: November 6, 2022
LONG DESCRIPTION: ERCOT identified an issue with some published Ancillary Service (AS) Award MW amounts for OD 11/06/2022. The Daylight Saving Time (DST) transition triggered an issue with the DAM AS Awards, due to the repeated hour. ERCOT will republish the AS awards as the original batch has incorrect or missing MW amount values for some hours. Market participants should review their AS Awards to determine if this issue has impacted their awarded amounts. Market Clearing Prices for Capacity (MCPCs) were not impacted.
