Background

Status:	Approved
Date Posted:	Apr 24, 2009
Sponsor:	Wind Coalition
Urgent:	No
Sections:	2.1, 2.2, 4.5.1, 4.5.10, 4.5.12 (new)
Description:	This Protocol Revision Request (PRR) specifies the process for Wind-powered Generation Resources (WGRs) to update Resource Plans and schedules every hour using the ERCOT provided most likely Short-Term Wind Power Forecast (STWPF) as the standard for accuracy. [Note - It is expected that AWS Truewind will be providing a forecast adjusted for turbine availability as a result of other pending Protocol changes.]
Reason:	Accurate Resource Plans and schedules provide ERCOT operations more certainty when deploying balancing and Resource specific Dispatch orders.
