NOTICE TYPE: M-A082213-01 Operations
SHORT DESCRIPTION: China Grove SPS Temporarily Disabled
INTENDED AUDIENCE: ERCOT Market Participants
DAYS AFFECTED: August 22, 2013
LONG DESCRIPTION: The China Grove Special Protection System (SPS) has been temporarily disabled today, August 22, 2013, due to the observation of intermittent changes in the direction of power flow on
the Morgan Creek to China Grove 138 kV double circuit lines. The China Grove SPS is not designed to address flow in more than one direction. Consequently, the SPS has been disabled, and the China Grove series reactors will be manually placed in and out of
service in the interim as necessary until the SPS can be modified to account for the change in system flow. Outage Scheduler should be referenced for status of the series reactors.
ADDITIONAL INFORMATION: Further details of the China Grove SPS can be found in the ERCOT Market Information System (MIS) under “Special Protection Systems and Remedial Action Plans” at
https://mis.ercot.com/pps/tibco/mis/Pages/Grid+Information/Long+Term+Planning. A Digital Certificate is required to access the MIS.
