SHORT DESCRIPTION: ERCOT Board approval of Real-Time Market (RTM) Price Corrections

INTENDED AUDIENCE: All Market Participants 

DAYS AFFECTED: March 29, 2025

LONG DESCRIPTION: On June 23, 2025, the ERCOT Board of Directors (ERCOT Board) reviewed price corrections for an event in which a Generic Transmission Constraint was incorrectly being considered in Security-Constrained Economic Dispatch (SCED). This impacted multiple SCED intervals on Operating Days (ODs) March 28 and 29, 2025.  See Market Notice M-B040225-01 for additional details.

The ERCOT Board determined that prices were significantly affected and directed ERCOT to implement the appropriate price corrections pursuant to ERCOT Protocol Section 6.3(7) for the Real-Time Market (RTM) for OD March 29, 2025.

ERCOT Board approval of these price corrections necessitates the issuance of RTM Resettlement Statements. A subsequent Market Notice will be posted for the RTM resettlements in accordance with ERCOT Protocol Section 9.5.7.

ADDITIONAL INFORMATION: The corrected prices will be posted in both CSV and XML formats under the RTM Price Corrections section of the Market Prices webpage on ERCOT.com.
