LONG DESCRIPTION: ERCOT will be implementing changes to the Outage Scheduler for the remaining grey-boxed portion of Nodal Protocol Revision Request (NPRR) 758, Improved Transparency for Outages Potentially Having a High Economic
Impact, between August 29 and August 31.
This NPRR will:

of Outages that might cause future congestion;
·
Encourage earlier submission of these Outages;
·
Formalize the process of rescheduling these Outages when they must be moved due to Forced Outages or later-arriving generator Outages; and
·
Provide improved transparency to Market Participants when Outages with this potential congestion impact are submitted with less than 90 days’ notice.
Specific items within this NPRR include:
·
Posting of High Impact Outages (HIOs) requested 90 days or less; and
·
Introduction of a Rescheduled Outage type in the Outage Scheduler
