SHORT DESCRIPTION:  Proposal to retire Elkton Switching Station Special Protection System
INTENDED AUDIENCE:  ERCOT Market Participants
DAY AFFECTED:  Comments due February 18, 2016

LONG DESCRIPTION:  ERCOT has received a proposal from Oncor Electric Delivery Company LLC (Oncor) to retire the Elkton Switching Station Special Protection System (SPS). The Elkton SPS was designed to monitor & relieve thermal violations on the Elkton to Forest Grove 138 kV line. Oncor has implemented a rebuild project in December 2015 to increase the static emergency rating of this 138 kV line from 114 MVA to 214 MVA (i.e., 897 A) and hence is proposing to retire the SPS.


The proposal to disable the Elkton Switching Station SPS is being reviewed by ERCOT. Comments on the proposal are due by February 18, 2016 and should be submitted to [log in to unmask]<mailto:[log in to unmask]> using the attached comment form.  Any questions or concerns submitted by this date will be addressed by ERCOT or Oncor.
ACTION REQUIRED:  Any comments to this proposal are due to ERCOT by February 18, 2016, using the attached form.
