Background
| Status: | Approved |
|---|---|
| Date Posted: | May 13, 2014 |
| Sponsor: | ERCOT |
| Urgent: | No |
| Sections: | 2.6.1, 6.2.6.3.6 |
| Description: | Adds a requirement for Under-Frequency Load Shedding (UFLS) and Under-Voltage Load Shedding (UVLS) systems Load restoration coordination consistent with that of manually shed Load for EEA 3 or a Constraint Management Plan. |
| Reason: | Paragraph (4) of Section 11.4, Mitigation Plan, states, "Restoration of any Load shed by executing the Mitigation Plan shall be coordinated with ERCOT." To improve reliability of the ERCOT System, ERCOT proposes similar language in Section 6.2.6.3.6 to provide a reasonable level of assurance that Load restoration will not exceed capability limits of Generation Resources or Transmission Facilities. Additionally, ERCOT proposes to use similar language in Paragraph (5) of Section 2.6.1 for consistency and clarity that coordination is expected for any of the Load shed restoration with UFLS, UVLS, or Constraint Management Plans with Load shed. |
