Background
| Status: | Approved |
|---|---|
| Date Posted: | Apr 25, 2023 |
| Sponsor: | ERCOT |
| Urgent: | No |
| Sections: | 6.5.9.3.2, 6.5.9.4, 6.5.9.4.1, and 6.5.9.4.2 |
| Description: | This Nodal Protocol Revision Request (NPRR) revises the Energy Emergency Alert (EEA) procedures to require a declaration of EEA Level 3 when Physical Responsive Capability (PRC) cannot be maintained above 1,500 MW and will require ERCOT to shed firm Load to recover 1,500 MW of reserves within 30 minutes. This NPRR also modifies the trigger levels for EEA Level 1 and EEA Level 2, changes the trigger for ERCOT’s consideration of alternative transmission ratings or configurations from Advisory to Watch when PRC drops below 3,000 MW, and restores a frequency trigger for the declaration of EEA Level 3 if the steady-state frequency drops below 59.8 Hz for any period of time. |
| Reason: | Addresses current operational issues |
