Project 2007-01 Underfrequency Load Shedding

Related Files

Status
Board Adopted: November 4, 2010

Filed with FERC: March 31, 2011

Order Effective

Enforcement Date

Purpose/Industry Need:
PRC-006 — Development and Documentation of Regional Reliability Organizations’ Underfrequency Load Shedding Programs
PRC-007 — Assuring Consistency with Regional UFLS Programs
PRC-009 — UFLS Performance Following an Underfrequency Event
The purpose of revising the above standards is to:

  1. Provide an adequate level of reliability for the North American bulk power systems – ensure each of the standards are complete and the requirements are set at an appropriate level to ensure reliability.
  2. Ensure they are enforceable as mandatory reliability standards with financial penalties - the applicability to bulk power system owners, operators, and users, and as appropriate particular classes of facilities, is clearly defined; the purpose, requirements, and measures are results-focused and unambiguous; the consequences of violating the requirements are clear.
  3. Incorporate other general improvements described in NERC’s Reliability Standards Development Plan: 2007-2009 (summarized and outlined in the Reliability Standard Review Guidelines attached as Appendix A).
  4. Consider the items mentioned in the Standard Review Forms (excerpted from NERC’s Reliability Standards Development  Plan: 2007-2009) attached as Appendix B, prepared by the NERC staff, which attempt to capture comments from the:
    • FERC NOPR (Docket # RM06-16-00 dated October 20, 2006),
    • FERC staff report dated May 11, 2006 concerning NERC standards submitted with ERO application,
    • Version 0 standards development (see note 1), and
    • Regional Fill-in-the-Blank Team (RRSWG ? a NERC working group involved with regional standards development).
    • The standard drafting team should also consider any other issues that were not completely captured but were stated or referenced in the above materials.
  5. Consider issues raised by the industry during the posting of the SAR for Project 2007-01 during the first comment period from November 29, 2006 through January 12, 2007, attached as Appendix C
  6. Satisfy the standards procedure requirement for five-year review of the standards.
