NOTICE DATE:  March 1, 2017

NOTICE TYPE:  W-A030117-01 Operations

SHORT DESCRIPTION:  Removal of the Liston Generic Transmission Constraint

INTENDED AUDIENCE:  ERCOT Market Participants

DAY AFFECTED:  March 8, 2017

LONG DESCRIPTION:  The Liston Generic Transmission Constraint (GTC) has been in service since November 2015.  This GTC was needed to resolve local stability issues associated with a temporary interconnection of a wind farm in South Texas.  The GTC is no longer needed because the wind farm recently commissioned its permanent interconnection.

The purpose of this notice is to provide contemporaneous notification to all ERCOT Market Participants about the removal of the Liston GTC.  ERCOT will cease posting limits for this GTC on March 8, 2017.

Details associated with all existing GTCs can be found on the ERCOT MIS Secure Area in the "Generic Transmission Constraints" portlet.  A Digital Certificate is required to access the MIS Secure Area.
