SHORT DESCRIPTION:  Implementation details of NPRR219, NOGRR050, and SCR783

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  September 27, 2016

LONG DESCRIPTION:  On September 27, 2016, Nodal Protocol Revision Request (NPRR) 219, Resolution of Alignment Items A33, A92, A106, and A150 - TSPs Must Submit Outages for Resource Owned Equipment and Clarification of Changes in Status of Transmission Element Postings, Nodal Operating Guide Revision Request (NOGRR) 050, Resolution of Reporting Issues Related to NPRR219, and System Change Request (SCR) 783, Outage Scheduler Enhancements -- Groups 2 and 3, Group Outage, Usability and Filtering Enhancements, will be implemented.

SCR783 was approved by the ERCOT Board on February 10, 2015. NPRR219 was initially approved by the ERCOT Board on October 19, 2010, and the Impact Analysis and Business Case were approved on February 10, 2015. NOGRR050 was initially approved by the ERCOT Board on October 19, 2010, and the revised Impact Analysis was approved on June 14, 2016.

NPRR219 changes the responsibility for submission of Planned and Maintenance Outages for Resource Entity-owned Transmission Facilities that are part of the ERCOT Transmission Grid and defined in the Network Operations Model from ERCOT to Resource Entities.

NOGRR050 removes the requirement for ERCOT to produce an Outage Scheduling-related report from the current Nodal Operating Guides and proposes inserting those requirements as grey-box language.

SCR783 provides group Outage, usability and filtering enhancements in the Outage Scheduler.

ADDITIONAL INFORMATION:  Pursuant to Nodal Protocol Section 21.6, Nodal Protocol Revision Implementation, and Nodal Operating Guide Section 1.3.6, Nodal Operating Guide Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
