Table of Contents

The Gist

NPRR930 clarifies the process that ERCOT can use to delay or cancel outages.  It first has to post an Advance Action Notice (AAN) a minimum of 24 hours before adjusting a resource’s outage schedule.  Further, resources can change their outage types to Forced to prevent ERCOT from adjusting their outage schedule.  Finally if a resource’s outage schedule is changed by ERCOT via an Outage Schedule Adjustment (OSA) they will be made whole to their costs.
