INTENDED AUDIENCE: Settlement Personnel 

DAYS AFFECTED: Operating Dates May 21- 23, 2026, April 2, 2026, and Nov 28, 2025

LONG DESCRIPTION: ERCOT posted and then removed the Real-Time Market Consolidated Operating Day Extracts (RTM CODE) on May 27th and May 28th due to issues with incomplete data sets following the 2026-R5 on-cycle release. The original extracts postings were missing several expected table sets for their associated operating days. This issue was the result of a configuration and performance update in the extract generation application. Due to this, the following operating dates and postings have been affected:

• Operating Days for Initials: May 21 - May 23, 2026
• 05/21/2026 Initial was posted on 05/27/2026 and removed on 05/28/2026. It was rerun and reposted on 05/29/2026 and posted within the allowable protocol timeline.
• UPDATE: Files were reposted at approximately 9:30 AM.
• Both 05/22/2026 and 05/23/2026 Initials were posted and removed on 05/28/2026. They are being rerun and reposted and are expected to post within the allowable protocol timeframe.
• UPDATE: Both files have been rerun and reposted. 05/22/2026 reposted at approximately 3:45 PM. 05/23/2026 reposted at approximately 6:30 PM.
• Operating Day for Final: April 2, 2026
• 04/02/2026 Final was posted on 05/27/2026 and removed on 05/28/2026. It is currently being rerun and will be reposted LATE as it is outside of the protocol time for delivery.
• UPDATE: Files were reposted at approximately 3:45 PM.
• Operating Day for True-Ups: November 28, 2025
• 11/28/2025 True-up was posted on 05/27/2026 and removed on 05/28/2026. It is currently being rerun and will be reposted LATE as it is outside of the protocol time for delivery.
• UPDATE: Files were reposted at approximately 3:45 PM.

ADDITIONAL INFORMATION: All extracts runs are operating as expected and posting to the Market Information System (MIS) certified area.
