NOGRR082 Synchronization with NPRR258 and Alignment of Primary Frequency Response Test Procedures

Approved Urgent sponsor ERCOT posted 2011-10-07 ercot.com

ReasonUpon implementation of NPRR258, Protocol Section 8.1.1.4.1, Regulation Service and Generation Resource/Controllable Load Resource Energy Deployment Performance, ERCOT will use High Sustained Limit (HSL) for calculating Estimated Primary Frequency Response (EPFR) which is a component of Generation Resource Energy Deployment Performance (GREDP) calculation. This NOGRR will align the EPFR requirement with how the test shall be conducted for IRRs since IRRs can have significant difference between installed capacity and HSL.
