Sponsor: John Dumas
Urgent: No
Sections: 6.2.1, Introduction 6.2.2 Design and Operating Requirements for ERCOT System Facilities
Description: This Nodal Operating Guide Revision Request (NOGRR) adds addtional monitoring and control requirements for Special Protection Systems (SPSs) that involve generation reduction to synchronize the Nodal Operating Guides with OGRR224.
Reason: ERCOT observed several SPS operations in 2008 that occurred under normal loading without any system disturbances. This NOGRR presented herein places an obligation on Resource owners who have an SPS to monitor fthe flows monitored by the SPS in the base case and reduce output as needed before the arming point of the SPS is reached.
