Background

Status: Approved
Date Posted: Dec 24, 2008
Sponsor: QSE Managers Working Group (QMWG)
Urgent: Yes
Sections: 6.5.1.1
Description: This Protocol Revision Request (PRR) will require a Wind-powered Generation Resource (WGR) Entity to provide Real Time meteorological information to ERCOT through its selected Qualified Scheduling Entity (QSE). It will also require ERCOT to establish procedures specifying the accuracy requirements of WGR meteorological information telemetry.
Reason: The site-specific meteorological information is necessary for ERCOT to produce the Short-Term Wind Power Forecast (STWPF) and Total ERCOT Wind Power Forecast (TEWPF) forecasts for WGRs. PRR763, Use of WGRPP as Planned Operating Level in Day-Ahead Resource Plan for WGRs, required the use of the forecasts in the scheduling process. The meteorological information is a requirement of the Nodal Protocols. This requirement needs to be specified in the current zonal Protocols for it to be enforceable.
