Status
The UFLS
standard drafting team is seeking comments on the
proposed second draft of the underfrequency load shedding program
requirements, including a proposed continent-wide standard — PRC-006-1.
The team has also posted the consideration of comments from posting the
UFLS Regional Reliability Standards Characteristics.
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:
-
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.
-
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.
-
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).
-
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.
-
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
-
Satisfy the standards procedure requirement for five-year review of
the standards.
