SHORT DESCRIPTION: Implementation of NPRR758, Improved Transparency for Outages Potentially having a High Economic Impact (Rescheduled Outages)
INTENDED AUDIENCE: Transmission Service Providers
DAY AFFECTED: August 29 - 31, 2017
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:
********* Identify Outages that have historically resulted in high congestion costs, as adjusted through a stakeholder review process to account for upgrades and other changes that would affect the fidelity of this list as an indicator 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
