NOTICE DATE: April 24, 2025
NOTICE TYPE: M-A091124-03 Operations
SHORT DESCRIPTION: Correction to Real-Time Market (RTM) Price Correction
INTENDED AUDIENCE: All Market Participants
DAYS AFFECTED: September 4, 2024; September 11, 2024
LONG DESCRIPTION: On April 7, 2025, the ERCOT Board of Directors (ERCOT Board) reviewed price corrections for an event that involved the usage of incorrect Resource telemetered megawatt (MW) values when a Qualified Scheduling Entity (QSE) sent suspect quality telemetry and directed ERCOT to implement the appropriate price corrections pursuant to Protocol Section 6.3(7). See Market Notices M-A091124-01 and M-A091124-02.
In preparing to implement this price correction, ERCOT identified an error in the input data used in the emergency operations Settlements and after correcting that error determined that the impacts to Settlement Statements for Operating Days (ODs) September 4 and September 11, 2024 did not meet the significance criteria of Protocol Section 6.3(7)(b) to qualify for a price correction. Accordingly, those two ODs were incorrectly included in the price correction proposal brought to the ERCOT Board and will not be resettled because of their ineligibility for correction.
For the remaining ODs for which the ERCOT Board’s approval applies, a subsequent Market Notice will be posted regarding the issuance of RTM Resettlement Statements in accordance with Protocol Section 9.5.7.
ADDITIONAL INFORMATION: ERCOT will present additional information on this amendment to the price correction at the May 5, 2025 meeting of the Wholesale Market Working Group (WMWG).
