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.

Reason: Accurate Resource Plans and schedules provide ERCOT operations more certainty when deploying balancing and Resource specific Dispatch orders.
