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.
