NOTICE DATE:  March 25, 2015
NOTICE TYPE:  M-A032515-01 Operations
SHORT DESCRIPTION:  Proposed Disabling of Monticello B – SPS #2
INTENDED AUDIENCE:  ERCOT Market Participants
DAY AFFECTED:  Comments due April 10, 2015
LONG DESCRIPTION:  ERCOT has received a proposal to disable the Monticello B Special Protection System (SPS #2) from Oncor Electric Delivery Company (Oncor).  The Monticello B SPS was designed to monitor and relieve thermal violations on the Monticello to Sulphur Springs, Monticello to Allen Switching Station, Monticello to Farmersville Switch and both Farmersville to Royse 345 kV lines. The exit strategy on file for this SPS is to upgrade these lines. However, Oncor is proposing to disable this SPS because of changed generation dispatch patterns in the region which have resulted in decreased thermal loading on lines monitored by the SPS.
The proposal to disable Monticello B SPS is being reviewed by ERCOT. Comments on the proposal are due by April 10, 2015 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 Staff or Oncor.
ACTION REQUIRED:  Any comments to this proposal are due to ERCOT by April 10, 2015, using the attached form.
ADDITIONAL INFORMATION:  Information regarding SPSs can be found on the Market Information System (MIS) on the Long-Term Planning<https://mis.ercot.com/pps/tibco/mis/Pages/Grid+Information/Long+Term+Planning> page in the “Special Protection Systems and Remedial Action Plans” portlet.
