NOGRR152 Restore Synchrony Between Contingency Planning for Minimum Level of Responsive Reserve Service and Real Time Contingency Analysis

Rejected sponsor Apex CAES, LLC, Calpine Corporation, First Solar Inc., GDF Suez Energy Marketing North America Inc., Golden Spread Electric Cooperative, Lower Colorado River Authority, Luminant Energy Company LLC, South Texas Electric Cooperative, SunEdison Inc., SunPower Corporation, and Talen Energy posted 2016-01-06 ercot.com

ReasonAddresses 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.
