NOTICE DATE:  January 11, 2019
NOTICE TYPE:  M-A062118-04 PGRR
SHORT DESCRIPTION:  Partial implementation Details of Planning Guide Revision Request (PGRR) 057 – Request for Resource Entities and Transmission Service Providers (TSPs) to provide to ERCOT a list of Geomagnetic Disturbance (GMD) event caused outages for use in the GMD vulnerability assessment
INTENDED AUDIENCE:  Resource Entities and TSPs
DAYS AFFECTED:  January 22, 2019 and March 31, 2019
LONG DESCRIPTION:  On January 22, 2019, ERCOT will partially implement Planning Guide language associated with PGRR057, Responsibilities for Performing GMD Vulnerability Assessments. Specifically, paragraph (2) of Section 6.11, Process for Developing Geomagnetically-Induced Current (GIC) System Models, will be unboxed.  Remaining portions of PGRR057 will be implemented at a later date.  PGRR057 aligns the Planning Guides with North American Electric Reliability Corporation (NERC) Reliability Standard TPL-007-1, Transmission System Planned Performance for Geomagnetic Disturbance Events, by identifying responsibilities for performing studies needed to complete GMD vulnerability assessments.
ACTION REQUIRED:  ERCOT requests that Resource Entities and TSPs provide their GMD event caused outages via e-mail to [log in to unmask]<mailto:[log in to unmask]> with “GMD Event” in the subject line by March 31, 2019.  Resource Entities and TSPs with no GMD event caused outages should so state in their email submission.
ADDITIONAL INFORMATION:  In addition to Resource Entities and TSPs, this notice is also issued to compliance contacts for all Generator Owners and Transmission Owners registered with NERC.
PGRR057<http://www.ercot.com/mktrules/issues/PGRR057> and associated documents can be found on the ERCOT website.
Pursuant to Planning Guide Section 1.2.6, Planning Guide Revision Implementation, ERCOT is required to provide notice as soon as practicable, but no later than ten days prior to implementation.
