NOTICE TYPE: M-B102126-01 Settlement Extracts
SHORT DESCRIPTION: Settlement extract posting schedule issues have been resolved and will now adhere to the required delivery timeline.
INTENDED AUDIENCE: Settlement Extract Recipients
DAYS AFFECTED: Monday, October 19, 2026
LONG DESCRIPTION: While investigating the issues covered in M-B082026-01, ERCOT identified a long standing operational issue that occasionally affected extract generation, causing some postings to fall behind their expected delivery schedule. The extracts listed below were delayed by at least two extract runs.
ERCOT has corrected the issue and implemented additional monitoring to help identify and prevent similar delays going forward. To bring the affected extracts back to their required delivery schedule, ERCOT performed additional reruns. All impacted extracts have returned to their expected delivery timeframe

ACTION REQUIRED: Market Participants will see the additional extracts posted in their associated folders on the Market Information System (MIS). The filenames will end with Rerun1, Rerun2, or Rerun3, depending on the number of reruns required. Market Participants should download and process the rerun files in sequential order, beginning with Rerun1, followed by Rerun2, and then Rerun3, if applicable.
