SHORT DESCRIPTION:  Discontinuing WGR forecasts by email
INTENDED AUDIENCE:  Resource Entities and QSEs with Wind-powered Generation Resources
DAY AFFECTED:  September 22, 2010
LONG DESCRIPTION:  The WGR's forecasts have been available through the zonal Extensible Markup Language (XML) Market User Interface (MUI) since the implementation of SCR 754 on June 24, 2009.  AWS will no longer be sending the WGR's forecasts by email and QSE will need to obtain their forecasts from the ERCOT participant's XML-based programmatic interface.
ACTION REQUIRED:  QSEs representing WGRs should ensure that they are able to retrieve their WGR's forecasts from the ERCOT participant's XML-based programmatic interface.

ADDITIONAL INFORMATION:  The XML query for Qualified Scheduling Entities (QSEs) representing Wind-powered Generation Resources (WGR) to download hourly WGR forecasts is specified in the ERCOT Participant Interface: XML query Section 6.5 (Query for AWS Wind Forecast).
