NOTICE DATE: November 23, 2022

NOTICE TYPE: M-B112322-01 Operations

SHORT DESCRIPTION: Implementation of Changes Related to FPP Wind and Solar Forecast Reports

INTENDED AUDIENCE: ERCOT Market Participants

DAYS AFFECTED: December 6 - 8, 2022

LONG DESCRIPTION: Between December 6 and 8, 2022, the Solar Generation Resource Power Potential Forecast (EMIL ID: NP4-736-SG | Report ID: 13482) and Wind Generation Resource Power Potential Forecast (EMIL ID: NP4-731-SG | Report ID: 12320) reports are being converted to Current Day Reports. As a result of this conversion, listed below are changes that will occur to these reports.

  1. Each report will have a new EMIL ID,Report Type ID and w new filenames (note that tokens 1, 2 and 6 in the file names will also change).

    Solar Generation Resource Power Potential Forecast
    Old EMIL Details: EMIL ID: NP4-736-SG | Report ID: 13482 New EMIL Details: EMIL ID: NP4-736-CD | Report ID: 22852 New File Names Examples: cdr.00022852.0000016DigitDUNS.YYYYMMDD.HHMMSSmss.SolarForecastNP4736_xml.zipcdr.00022852.0000016DigitDUNS.YYYYMMDD.HHMMSSmss.SolarForecastNP4736_csv.zip

    Wind Generation Resource Power Potential Forecast
    Old EMIL Details: EMIL ID: NP4-731-SG | Report ID: 12320 New EMIL Details: EMIL ID: NP4-731-CD | Report ID: 22853 New File Names Examples: cdr.00022853.0000016DigitDUNS.YYYYMMDD.HHMMSSmss.WindForecastNP4731_xml.zipcdr.00022853.0000016DigitDUNS.YYYYMMDD.HHMMSSmss.WindForecastNP4731_csv.zip

  2. Additionally, the CDR output for the reports in both CSV and XML format will change. An updated Current Day Reports XSD v6.42 has been posted to reflect the changed data outputs.
  3. Lastly, upon conversion, the existing wind and solar reports will no longer be associated with GetWGRPP/PVGRPP or GetSTWPF/STPPF. In order to obtain the pre-conversion data, MPs should use GetReport along with the Report Type ID used prior to the conversion (namely, Report Type ID 13482 for Solar Generation Resource Power Potential Forecast and Report Type ID 12320 for Wind Generation Resource Power Potential Forecast). Going forward, the new CDR reports above will be associated to the GetContent for WGRPP/STWPF/PVGRPP/STPPF.

Please note that the XML Notifications for Wind Generation Forecast and Solar Generation Forecast will remain the same and have no modifications as part of this effort.
