Sections: 4.2.2
Description: Current Protocols require that forecasted and actual wind power production be posted hourly. This Nodal Protocol Revision Request (NPRR) is twofold: Adds a new public report to be posted every five minutes that provides, on both a system-wide and regional basis, the five-minute actual wind power production for a rolling historical 60-minute period. (Note that this includes the current Real-Time value along with a rolling 60-minute history of five-minute actual values.) Changes the existing hourly report for Actual and Forecast Regional Wind Report to provide the following information on both a system-wide and regional basis: Aggregate Wind-powered Generation Resource (WGR) Power Output Aggregate Short-term Wind Power Forecast (STWPF) Aggregate Wind-powered Generation Resource Production Potential (WGRPP) Aggregate Current Operating Plan (COP) High Sustained Limits (HSLs) for On-Line WGRs These reports will compliment the new Public Aggregated Wind Dashboard proposed in System Change Request (SCR) 765, Public Aggregated Wind Dashboard.
Reason: To provide the market with near Real-Time wind power production data.
