W-A080219-01 Implementation of system change to account for dynamic voltage stability limits for the Panhandle Generic Transmission Constraint


NOTICE DATE:  August 2, 2019

NOTICE TYPE:  W-A080219-01 Operations

SHORT DESCRIPTION:  Implementation of system change to account for dynamic voltage stability limits for the Panhandle Generic Transmission Constraint

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  August 2, 2019

LONG DESCRIPTION:  ERCOT is implementing a change to its Real-Time systems for the Panhandle Generic Transmission Constraint (GTC).  This change is being implemented to account for a dynamic voltage stability issue for a particular outage scenario where the limit cannot be determined by the Voltage Stability Assessment Tool (VSAT) in Real-Time.

The purpose of this notice is to provide simultaneous notification to all ERCOT Market Participants of the system change being implemented, as it may impact limits associated with the Panhandle GTC.  ERCOT will discuss this issue in more detail at the Reliability and Operations Subcommittee (ROS) meeting on August 8, 2019, during the “ERCOT Reports” section of the agenda.

CONTACT:  If you have any questions, please contact your ERCOT Account Manager. You may also call the general ERCOT Client Services phone number at (512) 248-3900 or contact ERCOT Client Services via email at ClientServices@ercot.com.
