NPRR210  Wind Forecasting Change to P50, Synchronization with PRR841

Approved sponsor Morgan Stanley posted 2010-02-09 ercot.com
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.
