NPRR #210 · Revision Request
NPRR210 Wind Forecasting Change to P50, Synchronization with PRR841
ReasonThe P80 forecast provides an unrealistically low prediction of wind output resulting in overcommitment of RUC Resources. Implementation of this NPRR should allow ERCOT to commit fewer RUC Resources and still maintain reliability.

Summary
This Nodal Protocol Revision Request (NPRR) changes the wind forecasting methodology to use a 50% probability of exceedance calculation instead of an 80% for Reliability Unit Commitment (RUC) considerations. This NPRR would align the Nodal Protocols with changes made to the zonal Protocols pursuant to Protocol Revision Request (PRR) 841, Revise Total ERCOT Wind Power Forecast (TEWPF), which was approved by the ERCOT Board on 3/23/10.
