Status: Rejected

Urgent: No
Sections: 2.3.1.1
Description: Align consideration of the simultaneous loss of the South Texas Nuclear Project (STP) as a credible single contingency for purposes of determining the minimum amount of Responsive Reserve (RRS) as it is currently used in the Real-Time Contingency Analysis (RTCA).
Reason: Addresses current operational issues and restores alignment between the contingency planning for the minimum level of RRS and the transmission security analysis in RTCA that has been inadvertently lost as capacity upgrades were made to STP that are not captured in the RRS analysis. This alignment has become more important as the percentage of generation on the system that does not contribute with governor-like Primary Frequency Response can be in excess of 10,000 MW even during Summer peak conditons.
