Aug 25, 2022 12:20:46 PM Market price correction for SCED. ERCOT has completed its investigation and identified a need to perform a price correction for certain Real-Time Market Settlement Intervals between 06:15 and 20:45 on Operating Day 08/23/2022 due to loads associated with Distributed Energy Storage Resources (DESRs) being excluded from Load Zone Settlement Point Price calculations. Impacts range between $0.01/MWh and $0.12/MWh and are limited to Real-Time Settlement Point Prices (RTSPPs) for Load Zones. Corrections to the RTSPPs will be posted by 16:00 on 08/25/2022. Update to notification of SCED prices under investigation. ERCOT has completed its investigation and determined that impacts to Operating Day 08/24/2022 do not meet the necessary criteria for significance and ERCOT will not be performing a price correction for this Operating Day.
