NOTICE DATE: January 9, 2025
NOTICE TYPE: M-B010925-01 Operations
SHORT DESCRIPTION: Notice of issue with reports containing hourly solar forecast and hourly wind forecast related information.
INTENDED AUDIENCE: ERCOT Market Participants
DAYS AFFECTED: January 9, 2025
LONG DESCRIPTION: ERCOT has identified an issue with the following reports:
These reports are posted every hour and include system-wide and regional STWPF/STPPF and WGRPP/PVGRPP values produced by each forecast model for On-Line WGRs/PVGRs for the rolling historical 48-hour period and the rolling future 168-hour period, and also indicates which forecast model is used for each region to populate Current Operating Plans (COPs).
To account for potential extreme weather impacts under the ongoing weather conditions, a change was made in the selection of the forecast model on Monday, January 6, 2025. This change caused both reports to stop populating the ‘System_Total’ Region forecast and the ‘In Use Flag’ indicating which forecast model was in use for hours where forecast selection changes were made. This issue began impacting reports posted after 10:00 AM on January 6, 2025.
ERCOT is working on a solution for the identified issues, and will provide a follow up Market Notice once these issues are resolved.
