| Sponsor: | ERCOT |
| Urgent: | Yes |
| Sections: | 8C |
| Description: | This Nodal Operating Guide Revision Request (NOGRR) synchronizes the Nodal Operating Guides with Nodal Protocol Revision Request (NPRR) 258, Synchronization with PRR824 and PRR833 and Additional Clarifications, and revises the frequency response test procedure to be applicable to Intermittent Renewable Resources (IRRs). |
| Reason: | Upon 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. |
