PETITION OF THE
NORTH AMERICAN ELECTRIC RELIABILITY CORPORATION
FOR APPROVAL OF REVISED AND RETIRED RELIABILITY STANDARDS
UNDER THE NERC STANDARDS EFFICIENCY REVIEW
Pursuant to Section 215(d)(1) of the Federal Power Act (“FPA”) 1 and Section 39.5 2 of the
Federal Energy Regulatory Commission’s (“FERC” or “Commission”) regulations, the North
American Electric Reliability Corporation (“NERC”) 3 hereby submits for Commission approval:
(i) the retirement of ten currently effective Reliability Standards in their entirety, without
replacement; and (ii) four proposed revised Reliability Standards, in which individual
requirements from the currently effective versions are retired.
As discussed more fully herein, the proposals discussed in this petition originate from the
first phase of work under NERC’s Standards Efficiency Review. This initiative, which began in
2017, reviewed the body of NERC Reliability Standards to identify those Reliability Standards
and requirements that were administrative in nature, duplicative to other standards, or provided no
benefit to reliability. The retirement proposals described in this petition are the first step toward
achieving a more streamlined, effective, and efficient body of Reliability Standards. None of the

proposed retirements would have an adverse impact on reliability. The specific proposals
addressed in this petition are as follows.
First, NERC requests that the Commission approve the retirement of ten currently effective
Reliability Standards in their entirety. The Reliability Standards proposed for retirement are as
follows:
•

FAC-013-2 – Assessment of Transfer Capability for the Near-term Transmission
Planning Horizon

•

INT-004-3.1 – Dynamic Transfers

•

INT-010-2.1 – Interchange Initiation and Modification for Reliability

•

MOD-001-1a – Available Transmission System Capability

•

MOD-004-1 – Capacity Benefit Margin

•

MOD-008-1 – Transmission Readability Margin Calculation Methodology

•

MOD-020-0 – Providing Interruptible Demands and Direct Control Load Management
Data to System Operators and Reliability Coordinators

•

MOD-028-2 – Area Interchange Methodology

•

MOD-029-2a – Rated System Path Methodology

•

MOD-030-3 – Flowgate Methodology

NERC has previously proposed the retirement of the MOD Reliability Standards listed
above (excluding MOD-020-0) in connection with its petition for approval of Reliability Standard
MOD-001-2, filed in Docket No. RM14-7-000 on February 10, 2014. 4 On June 7, 2019, NERC
filed a Notice of Withdrawal in that proceeding to withdraw its February 10, 2014 petition.

Petition of NERC for Approval of Proposed Reliability Standard MOD-001-2 and Retirement of Reliability
Standards MOD-001-1a, MOD-004-1, MOD-008-1, MOD-028-2, MOD-029-1a and MOD-030-2, Docket No. RM147-000.

2

Second, NERC requests that the Commission approve four proposed Reliability Standards,
as shown in Exhibit A, as just, reasonable, not unduly discriminatory or preferential, and in the
public interest. In these proposed Reliability Standards, NERC proposes to revise the currently
effective versions of the standards to retire individual requirements that are not needed for
reliability. The proposed Reliability Standards are as follows:
•

FAC-008-4 – Facility Ratings

•

INT-006-5 – Evaluation of Interchange Transactions

•

INT-009-3 – Implementation of Interchange

•

PRC-004-6 – Protection System Misoperation Identification and Correction

With respect to the proposed Reliability Standards, NERC requests that the Commission
also approve: (i) the associated Violation Risk Factors (“VRFs”) and Violation Severity Levels
(“VSLs”) (Exhibit D), which are generally unchanged from the currently effective versions of
those standards; and (ii) the retirement of currently effective Reliability Standards FAC-008-3,
INT-006-4, INT-009-2.1, and PRC-004-5(i).
Last, NERC requests that the Commission approve the associated implementation plan for
the proposed retired and revised Reliability Standards discussed above (Exhibit B).
As required by Section 39.5(a) 5 of the Commission’s regulations, this petition presents the
technical basis and purpose of the proposed Reliability Standards and retirements, a demonstration
that the proposals meet the criteria identified by the Commission in Order No. 672 6 (Exhibit C),
and a summary of the standard development history (Exhibit F). The NERC Board of Trustees

This petition is organized as follows: Section I of the petition presents an overview of the
Standards Efficiency Review and a summary of the proposals in this filing. Section II of the
petition provides the individuals to whom notices and communications related to the filing should
be provided. Section III provides background on the regulatory structure governing the Reliability
Standards approval process. This section also provides information on the development of the
proposals through Project 2018-03 Standards Efficiency Review Retirements. Sections IV and V
of the petition provide an overview of each of the Reliability Standard proposals and the
justification supporting the proposals. Section VI of the petition provides a summary of the
proposed implementation plan.
THE STANDARDS EFFICIENCY REVIEW
NERC’s mission is to assure effective and efficient reduction of risks to the reliability and
security of the North American Bulk Power System (“BPS”). 7 Mandatory Reliability Standards
play an integral role in helping NERC achieve its mission of a highly reliable and secure grid.
After a decade of developing and implementing mandatory Reliability Standards in the United
States, NERC launched the Standards Efficiency Review in 2017. This comprehensive, multi-year
review project comprises a key element of NERC’s plan to achieve its long-term strategic goal of
establishing risk-based controls to minimize BPS reliability risk while also driving operational

efficiencies and effectiveness. 8 This project also marks an important milestone in the maturity of
NERC’s standard development program.
The Commission approved the first set of mandatory Reliability Standards in Order No.
693, issued in 2007. 9 In the intervening years, NERC invested significant resources to develop
new and revised mandatory Reliability Standards to address Commission directives and emerging
risks. NERC also invested significant time and effort to improve the quality, content, and
organization of Reliability Standards. Notable achievements include:
•

The evolution in standards-writing from a highly detailed, prescriptive approach to one
that is “results-based,” whereby standards are written to provide entities with built-in
flexibility to achieve the stated reliability goal.

•

The retirement of 34 Reliability Standard requirements that were redundant,
administrative, or otherwise unnecessary and where violations posed a lesser risk to the
reliability of the BPS, under the “paragraph 81” project. 10

•

The revision and streamlining of entire families of Reliability Standards, including the
INT Reliability Standards 11 and the TOP and IRO Reliability Standards. 12

•

The implementation of enhanced processes for performing periodic reviews of
Reliability Standards, including a new grading process to measure content and quality.

In addition to these standards development-related efforts, NERC and the Regional Entities
have completed the implementation of risk-based compliance and enforcement processes across
the ERO Enterprise.

Through its experience successfully completing over 100 standards projects, and informed
by the improvement efforts highlighted above, NERC has developed a more sophisticated
understanding of what a Reliability Standard should be and how it should be written. With the
benefit of this experience, NERC determined that it was an appropriate time to initiate a
comprehensive and critical review of the body of NERC Reliability Standards. At this time,
approximately 475 continent-wide Reliability Standard requirements are in effect in the United
States, addressing various aspects of BPS planning, operations, and cyber and physical security.
NERC initiated the Standards Efficiency Review to determine whether there were opportunities to
improve the overall effectiveness and efficiency of its Reliability Standards consistent with its
regulatory philosophy, which consists of several key elements including the following:
•

Reliability Standards should be developed using a results-based approach that
focuses on performance, risk management, and entity capabilities, rather than
prescribing specific processes for an entity to follow.

•

Reliability Standards should be focused on advancing reliability; they should not
prescribe commercial business practices which do not contribute directly to
reliability.

•

Reliability Standard requirements should be organized logically and efficiently,
both to aid ease of use and to avoid duplication and conflict among requirements.

For the first phase of work, review teams consisting of industry experts in Real-time
operations, long-term planning, and operations planning performed a comprehensive review of the
operations and planning Reliability Standards (i.e., excluding CIP). The purpose of this review
was to identify Reliability Standard requirements that provide little or no benefit to reliability and
should be retired. An important part of this review was exploring the relationships between the
different Reliability Standards in a deeper way than would be feasible during a targeted periodic
review of a Reliability Standard or Reliability Standard family. This in-depth review allowed
NERC to identify requirements that are not necessary for reliability or that are redundant to other

6

requirements. The review process was conducted in an open and transparent manner, with broad
industry participation. NERC then initiated the standard development process to consider the
retirement recommendations resulting from the phase one work.
As discussed more fully in this petition, NERC proposes to retire 73 requirements and one
requirement part, including the retirement of 10 Reliability Standards in their entirety. 13 (NERC
has also filed a notice to withdraw its 2014 petition for approval of proposed Reliability Standard
MOD-001-2.) The proposals include the following Reliability Standards families: Interchange
Scheduling and Coordination (“INT”); Facilities Design, Connections, and Maintenance (“FAC”);
Modeling, Data, and Analysis (“MOD”); and Protection and Control (“PRC”). None of the
proposals discussed in this petition would have an adverse impact to reliability. To the contrary,
NERC’s proposals would benefit reliability by allowing entities to focus their resources on those
Reliability Standard requirements that promote the reliable operation and planning of the BPS and
avoid unnecessary regulatory burden. NERC therefore respectfully requests that the Commission
approve the proposals described in this petition as just, reasonable, not unduly discriminatory or
preferential, and in the public interest.
Work continues under the second phase of the Standard Efficiency Review to consider
recommendations for Reliability Standard revisions that would further improve the efficiency of
the body of NERC Reliability Standards, such as through consolidation of Reliability Standard
requirements. The review teams are also expected to consider recommendations for standardsbased improvements that would further reduce inefficiencies and promote effectiveness going

13

Concurrently with this filing, NERC has submitted a separate petition addressing the retirement of four
requirements related to next-day operations planning, which also resulted from work under the first phase of the
Standards Efficiency Review. See Petition of the North American Electric Reliability Corporation for Approval of
Reliability Standards IRO-002-7, TOP-001-5, and VAR-001-6 Developed under the NERC Standards Efficiency
Review, filed June 7, 2019 (docket pending).

approval at the appropriate time.

BACKGROUND
Regulatory Framework
By enacting the Energy Policy Act of 2005, 14 Congress entrusted the Commission with the
duties of approving and enforcing rules to ensure the reliability of the BPS, and with the duties of
certifying an ERO that would be charged with developing and enforcing mandatory Reliability
Standards, subject to Commission approval. Section 215(b)(1) 15 of the FPA states that all users,
owners, and operators of the BPS in the United States will be subject to Commission-approved
Reliability Standards. Section 215(d)(5) 16 of the FPA authorizes the Commission to order the ERO
to submit a new or modified Reliability Standard. Section 39.5(a) 17 of the Commission’s
regulations requires the ERO to file with the Commission for its approval each new Reliability

Standard that the ERO proposes should become mandatory and enforceable in the United States,
and each modification to a Reliability Standard that the ERO proposes should be made effective.
The Commission is vested with the regulatory responsibility to approve Reliability
Standards that protect the reliability of the BPS and to ensure that Reliability Standards are just,
reasonable, not unduly discriminatory or preferential, and in the public interest. Pursuant to
Section 215(d)(2) of the FPA 18 and Section 39.5(c) 19 of the Commission’s regulations, the
Commission will give due weight to the technical expertise of the ERO with respect to the content
of a Reliability Standard.
NERC Reliability Standards Development Procedure
The proposed Reliability Standards and standard retirements discussed in this petition were
developed in an open and fair manner and in accordance with the Commission-approved
Reliability Standard development process. NERC develops Reliability Standards in accordance
with Section 300 (Reliability Standards Development) of its Rules of Procedure and the NERC
Standard Processes Manual. 20
In its order certifying NERC as the Commission’s ERO, the Commission found that
NERC’s rules provide for reasonable notice and opportunity for public comment, due process,
openness, and a balance of interests in developing Reliability Standards, 21 and thus satisfy several
of the Commission’s criteria for approving Reliability Standards. 22 The development process is
open to any person or entity with a legitimate interest in the reliability of the BPS. NERC considers

the comments of all stakeholders. Stakeholders must approve, and the NERC Board of Trustees
must adopt, a new or revised Reliability Standard before NERC submits the Reliability Standard
to the Commission for approval. Similarly, stakeholders and the NERC Board of Trustees must
approve the retirement of a Reliability Standard before the retirement is submitted to the
Commission for approval.
Project 2018-03 Standards Efficiency Review Retirements
In 2018, NERC initiated Project 2018-03 Standards Efficiency Review Retirements to
consider the Reliability Standard Retirement recommendations from the first phase of the
Standards Efficiency Review. In total, the Project 2018-03 standard drafting team evaluated
recommendations to: (i) withdraw one proposed Reliability Standard in its entirety, consisting of
six requirements; and (ii) retire 99 Reliability Standard requirements and one requirement part,
including the retirement of 12 Reliability Standards in their entirety.
For the reasons explained in Exhibit E, the standard drafting team determined to: (i)
withdraw one proposed Reliability Standard; and (ii) retire 77 Reliability Standard requirements
and one requirement part, including the 73 requirements and one requirement part in the INT,
FAC, PRC, and MOD Reliability Standards that are addressed in this petition. For those Reliability
Standards in which individual requirements are proposed for retirement, the standard drafting team
developed a new version of the Reliability Standard in which the text of the retired requirement is
replaced with the term “Reserved,” with corresponding revisions made as necessary to the VSLs
and measures.
Each of the proposed standards and retirements were posted for formal comment and ballot
from February 27, 2019 to April 12, 2019 and for final ballot from April 23, 2019 to May 2, 2019.
Having achieved the requisite quorum and ballot body approval percentages, the NERC Board of

10

Trustees adopted the proposed standards and approved the proposed retirements on May 9, 2019.
A summary of the development history and the complete record of development is attached to this
petition as Exhibit F.
JUSTIFICATION FOR APPROVAL – PROPOSED STANDARD RETIREMENTS
In this petition, NERC proposes for Commission approval the retirement of ten Reliability
Standards in their entirety:
•

FAC-013-2 – Assessment of Transfer Capability for the Near-term Transmission
Planning Horizon

•

INT-004-3.1 – Dynamic Transfers

•

INT-010-2.1 – Interchange Initiation and Modification for Reliability

•

The MOD A Reliability Standards (MOD-001-1a – Available Transmission System
Capability; MOD-004-1 – Capacity Benefit Margin; MOD-008-1 – Transmission
Readability Margin Calculation Methodology; MOD-028-2 – Area Interchange
Methodology; MOD-029-2a – Rated System Path Methodology; MOD-030-3 –
Flowgate Methodology); and

•

MOD-020-0 – Providing Interruptible Demands and Direct Control Load Management
Data to System Operators and Reliability Coordinators

For the reasons set forth in this section, none of these Reliability Standards are necessary
for reliability. Therefore, the retirement of these Reliability Standards would not have an adverse
impact on reliability and would be in the public interest. NERC respectfully requests that the
Commission approve the retirement of these Reliability Standards, effective in accordance with
the proposed implementation plan discussed in Section VI.
Reliability Standard FAC-013-2
Procedural History
The Commission approved Reliability Standard FAC-013-2 – Assessment of Transfer

11

Capability for the Near-Term Transmission Planning Horizon in 2011. 23 The standard was
originally developed to address Commission directives in Order Nos. 69324 and 729 25 to require
entities to perform an annual assessment of transfer capability in the planning horizon and to do
so using data inputs and modeling assumptions that are consistent with other planning uses. In
2013, the Commission approved the retirement of Requirement R3 following NERC’s “paragraph
81” initiative. 26
Justification for Retirement
The purpose of Reliability Standard FAC-013-2 is “to ensure that Planning Coordinators
have a methodology for, and perform an annual assessment to identify potential future
Transmission System weaknesses and limiting Facilities that could impact the Bulk Electric
System’s (‘BES’) ability to reliably transfer energy in the Near-Term Transmission Planning
Horizon.” In approving the standard, the Commission noted the standard’s purpose as a planning
tool with a regional focus, rather than a mechanism for ensuring that individual systems are
planned to reliably meet projected load and known transmission uses. 27 In the intervening years,
NERC determined that the standard is not needed for BES reliability and is primarily

administrative in nature, and should therefore be retired. The specific reasons for this
determination are described below.
First, the requirement for Planning Coordinators to have a methodology for and to perform
an annual assessment of Transfer Capability for a single year in the Near-Term Transmission
Planning Horizon does not benefit System reliability beyond that provided by other Reliability
Standards. Reliability Standard TPL-001-4, which was approved by the Commission in 2013,28
requires Transmission Planners and Planning Coordinators to prepare an annual Planning
Assessment of its portion of the BES. Requirement R1.1.5 of this standard requires that the System
models used for the Planning Assessment represent “known commitments for Firm Transmission
Service and Interchange.” 29 The additional Transfer Capability assessment required by FAC-0132 serves only a market function; it does not provide for System reliability.
Second, NERC has determined that the Transfer Capability assessment is not an indicator
of BES reliability. Reliability Standard FAC-013-2 does not require specific performance metrics
or coordination among functional entities. Individual Planning Coordinators develop their own
methodologies that may be very different from each other. Impacted functional entities, such as
the Transmission Planner, do not have meaningful input into the methodology or analysis. The
standard does not specify performance metrics, nor does it define acceptable BES performance.
Entities that receive the methodology or assessment results are not obligated to use, or even
consider, the information in their assessments. Further, the standard requires that the assessment
be performed for only one year in the Near-Term Transmission Planning Horizon in the Planning

The relevant language is carried forward in Requirement R1.1.4 in proposed Reliability Standard TPL-0015. Proposed Reliability Standard TPL-001-5 was filed for approval on December 7, 2018 in Docket No. RM19-10000.

Coordinator’s discretion. 30 For these reasons, NERC has determined that these assessments are not
useful for regional reliability planning purposes.
In light of these considerations, NERC has determined that Reliability Standard FAC-0132 provides little or no benefit to reliability and should be retired. Should an individual entity find
the Transfer Capability assessments specified in this standard useful for its own planning purposes,
it may continue to perform them voluntarily.
Reliability Standard INT-004-3.1
Procedural History
The Commission approved Reliability Standard INT-004-3.1 – Dynamic Transfers in
2014. 31 The standard was last substantively revised through a larger project to revise and
consolidate the INT family of Reliability Standards. Requirements R1 and R2 were originally
drafted to be applicable to the Purchasing-Selling Entity; however, in 2015, the Commission
approved changes to the NERC Rules of Procedure that removed the Purchasing-Selling Entity
from the NERC Compliance Registry, 32 effectively retiring those requirements.
Justification for Retirement
The purpose of Reliability Standard INT-004-3.1 is to “ensure that Dynamic Schedules and
Pseudo-Ties are communicated and accounted for appropriately in congestion management
procedures.” NERC determined that it is appropriate to retire this standard as the substance relates
primarily to commercial or business practices and the standard itself provides little, if any, benefit

30

The Near-Term Transmission Planning Horizon is defined in the NERC Glossary as “The transmission
planning period that covers Year One through five.”

to reliability.
As noted above, Requirements R1 and R2 have been effectively retired since 2015 with
the removal of the Purchasing-Selling Entity function from the NERC Compliance Registry. The
remaining requirement, Requirement R3, refers to implementation or operation of only those
“Pseudo-Ties that are included in the NAESB Electric Industry Registry publication in order to
support congestion management procedures.” Interchange scheduling and congestion are elements
that impact transmission costs, rather than the reliable management of the BES. The requirement
itself provides no benefit to reliability. Therefore, the retirement of Reliability Standard INT-0043.1 would have no adverse impact on reliability and is in the public interest.
Reliability Standard INT-010-2.1
Procedural History
The Commission approved Reliability Standard INT-010-2.1 – Interchange Initiation and
Modification for Reliability in 2014. 33 NERC last revised the standard as part of a larger project
to revise and consolidate the INT family of Reliability Standards. At that time, modest revisions
were made to the terminology used in the requirements and the entity responsible for each task.
The prior version of the standard, INT-010-1, was approved by the Commission in Order No.
693. 34
Justification for Retirement
The purpose of Reliability Standard INT-010-2.1 is “to provide guidance for required
actions on Confirmed Interchange or Implemented Interchange to address reliability.” NERC
determined that it is appropriate to retire this Reliability Standard as it relates primarily to

33

N. Am. Elec. Reliability Corp., Docket No. RD14-4-000 (June 30, 2014) (delegated letter order) (approving
INT-010-2). The Commission approved errata version INT-010-2.1 on Nov. 26, 2014 by delegated letter order in the
same proceeding.

commercial or business practices and provides little, if any, benefit to reliability.
Reliability Standard INT-010-2.1 Requirement R1 provides that a Balancing Authority that
experiences a loss of resources or other reliability needs covered by an energy sharing agreement
shall ensure a Request for Interchange is submitted with a start time no more than 60 minutes
beyond the resource loss. Reliability Standard INT-010-2.1 Requirement R2 provides that a Sink
Balancing Authority shall ensure that a Reliability Adjustment Arranged Interchange reflecting a
modification is submitted within 60 minutes of the start of the modification if the Reliability
Coordinator directs modification of a Confirmed Interchange or Implemented Interchange for
actual or anticipated reliability-related reasons. Reliability Standard INT-010-2.1 Requirement R3
provides that a Sink Balancing Authority shall ensure that a Request for Interchange is submitted
reflecting that Interchange Schedule within 60 minutes of the start of the scheduled Interchange if
a Reliability Coordinator directs the scheduling of Interchange for actual or anticipated reliabilityrelated reasons.
Notwithstanding the references in these requirements to “reliability” and “reliabilityrelated reasons,” the requirements of Reliability Standard INT-010-2.1 ultimately relate primarily
to commercial or business practices; specifically, the timing of Requests for Interchange. The
NAESB WEQ-004 Coordinate Interchange Business Practice Standards (specifically, WEQ-0041 and WEQ-004-8) provide more stringent requirements. 35 The NERC Independent Experts
Review Panel recommended the retirement of the previous version of this Reliability Standard,
INT-010-1, in 2013, due to overlap with the NAESB Electronic Tagging Functional

35

In the interest of continued coordination between NERC and NAESB on standards development matters,
NERC has provided notice to NAESB of the INT proposals described in this filing so it may determine whether to
initiate action to review or revise its WEQ Business Practice Standards.

16

Specification. 36 Based on these considerations, and informed by its experience implementing the
INT-010 standard, NERC has determined that Reliability Standard INT-010-2.1 provides little, if
any, benefit to the reliability of the BPS and should be retired.
Reliability Standards MOD-001-1a, MOD-004-1, MOD-008-1, MOD-028-2,
MOD-029-2a, and MOD-030-3
Procedural History

MOD-030-2 – Flowgate Methodology (superseded by MOD-030-3, approved in

These Reliability Standards were developed in response to the Commission’s directives in
Order No. 890 43 and Order No. 693 44 to develop Reliability Standards to provide for consistency
and transparency in the methodologies used by transmission providers to calculate ATC.
On February 10, 2014, NERC filed a petition for approval of proposed Reliability Standard
MOD-001-2 and the retirement of Reliability Standards MOD-001-1a, MOD-004-1, MOD-008-1,
MOD-028-2, MOD-029-1a, and MOD-030-2. 45 In this petition, NERC proposed to retire the
majority of the existing MOD A Reliability Standard requirements and retain, in proposed
Reliability Standard MOD-001-2, only six requirements it believed were necessary for reliability.
NERC’s proposed MOD-001-2 implementation plan was designed to provide NAESB the
opportunity to consider, through its standards development process, which, if any, of the
commercial or business practice related requirements from the existing MOD A standards should
be incorporated into the WEQ Business Practice Standards.

42
Id. In Reliability Standard MOD-030-3, NERC revised the prior version by incorporating the new definition
of Remedial Action Scheme and eliminating use of the term Special Protection System.

In Order No. 890, the Commission sought to address and remedy continued opportunities for undue
discrimination under the pro forma Open Access Transmission Tariff adopted in Order No. 888. Among other things,
the Commission sought to standardize the manner in which ATC/AFC was calculated to address market-related
concerns that a lack of a consistent and transparent methodology could lead to undue discrimination for providing
open access transmission service. Id. at P 68. The Commission also asserted that a lack of consistent, industry-wide
calculation standards could pose a threat to the BPS because “a transmission provider might not know of its neighbors’
system conditions affecting its own ATC values.” See id. at 195.

45
Petition of NERC for Approval of Proposed Reliability Standard MOD-001-2 and Retirement of Reliability
Standards MOD-001-1a, MOD-004-1, MOD-008-1, MOD-028-2, MOD-029-1a and MOD-030-2, Docket No. RM147-000 (Feb. 10, 2014) (“MOD-001-2 Petition”).

18

On June 19, 2014, the Commission issued a Notice of Proposed Rulemaking proposing to
approve Reliability Standard MOD-001-2 and the retirement of the existing MOD A Reliability
Standards. 46 The Commission also sought comment on aspects of NERC’s proposal regarding
coordination with NAESB on incorporating commercial or business practice related requirements
in the NAESB WEQ Business Practice Standards. On September 25, 2015, NAESB submitted a
final status report to the Commission explaining that it had completed the development of new and
revised WEQ Business Practice Standards to include commercially relevant requirements from the
existing MOD A Reliability Standards being proposed for retirement. 47
As a result of work performed under the Standards Efficiency Review, and as discussed
further below, NERC determined that the existing MOD A Reliability Standards are not needed
for reliability and should be retired independently of Commission action on proposed Reliability
Standard MOD-001-2. Further, NERC determined that proposed Reliability Standard MOD-0012 is not needed for reliability and should be withdrawn. Accordingly, NERC filed a notice to
withdraw the MOD-001-2 Petition in Docket No. RM14-7-000 concurrently with the filing of
this petition. In the interest of continued coordination between NERC and NAESB on standards
development matters, NERC has provided notice to NAESB of the MOD proposals described in
this filing. NERC’s proposals, however, are not contingent on any NAESB action.
Justification for Retirement
MOD-001-1a serves as an umbrella standard that contains the generic requirements
applicable to determining ATC and AFC, and requires each applicable entity to select and
implement one or more of the three methodologies found in MOD-028-2 (Area Interchange

Methodology), MOD-029-2a (Rated System Path Methodology), and MOD-030-3 (Flowgate
Methodology). MOD-004-1 and MOD-008-1 provide for the calculation, verification,
preservation, and use of Capacity Benefit Margin (“CBM”) and Transmission Reliability Margin
(“TRM”), respectively, which are inputs into ATC/AFC calculations.
As noted in NERC’s MOD-001-2 Petition, NERC has previously concluded that many of
the requirements in the existing MOD A Reliability Standards provide little or no reliability benefit
and serve only a commercial function. 48 As NERC noted in that filing:
ATC/AFC values do not directly control the operation of the BulkPower System. Transmission Operators are ultimately responsible
for operating the grid in a reliable manner consistent with System
Operating Limits, not ATC/AFC values. NERC’s Reliability
Standards prohibit the scheduling and delivery of transmission
service if such action would cause a violation of System Operating
Limits or otherwise adversely affect reliability, regardless of the
amount of ATC or AFC that is posted and sold by the Transmission
Service Provider. It is the Transmission Operator’s responsibility,
when operating its system in Real-time, to monitor changing system
conditions and respond to any events, such as a facility exceeding
its System Operating Limit. 49
At that time, NERC concluded that ATC/AFC determinations had the potential to influence
reliability, insofar as they could lead to the possibility of oversold conditions that could trigger the
need for the Transmission Operator to take corrective action to maintain system reliability. To that
end, NERC proposed Reliability Standard MOD-001-2 to require that: (i) entities that determine
ATC/AFC and/or Total Transfer Capability (“TTC”)/Total Flowgate Capacity (“TFC”) do so in a
manner that accounts for system limits and relevant system conditions; and (ii) entities share the
methodologies and data used to determine ATC/AFC, TTC/TFC, CBM, and TRM with other

20

entities that need such information for their own determinations or to operate or plan the BulkPower System in a reliable manner.
As the Commission had not yet taken action on the proposed MOD-001-2 Reliability
Standard, NERC included both the existing MOD A Reliability Standards and proposed Reliability
Standard MOD-001-2 in the scope of the Standards Efficiency Review and the subsequent standard
development project. NERC reaffirmed that the existing MOD A Reliability Standards should be
retired. Further, NERC determined that the proposed MOD-001-2 standard, in which certain
elements of the existing MOD A standards would be retained, would provide little, if any, benefit
to reliability if approved and should therefore be withdrawn. The reasons for this determination
are discussed below.
The existing MOD A Reliability Standards provide little, if any, benefit to the reliable
operation of the BPS. ATC and AFC, as well as e-Tags, are commercially-focused elements,
facilitating interchange and balancing of interchange. System Operators are ambivalent to these
commercial arrangements. System Operators monitor Real-time flows to maintain reliability of
the BPS according to System Operating Limits and Interconnection Reliability Operating Limits.
If a scheduled interchange would violate either of these limits, the System Operators must
disregard the scheduled interchange and operate the System within its actual reliability limits.
While NERC proposed to retain certain elements of the MOD A Reliability Standards in
proposed Reliability Standard MOD-001-2 to promote operator awareness of potential oversold
conditions, NERC has since determined that the proposed standard should be withdrawn.
Requirements R1 through R4 of proposed Reliability Standard MOD-001-2 would require
applicable entities that determine TFC/TTC, AFC/ATC, CBM, or TRM values, respectively, to
develop methodologies or implementation documents describing how it determines such values.

21

Requirement R5 would require that applicable entities respond to requests for clarification of
methodologies or implementation documents and to provide such documents upon request, where
these documents are not publicly available on the Open Access Same-Time Information System
(“OASIS”) or the entity’s website.
Upon further review, NERC has determined that these requirements are administrative in
nature or relate expressly to commercial or business practices and would not advance reliability.
Entities are not obligated to determine the values specified in the requirements, nor is any criteria
imposed on their determination. Further, as Real-time flows are influenced by a number of factors
beyond commercial arrangements, having access to documented ATC/AFC, TTC/TFC, CBM, and
TRM methodologies under MOD-001-2 would provide little benefit to the System Operator
maintaining the reliability of the System in Real-time.
As noted above, System Operators must monitor Real-time flows on their Systems and
operate their Systems within actual reliability limits. The FAC Reliability Standards, specifically
Reliability Standards FAC-011-3 and FAC-014-2, require a consistent methodology for
calculating System Operating Limits and Interconnection Reliability Operating Limits between
the Reliability Coordinator and Transmission Operator. Reliability Standard TPL-001-4, which
became effective in 2015, requires each planning entity to share the results of its system planning
studies (Requirement R8). These requirements provide for the coordination needed for reliability.
Therefore, NERC has filed a notice to withdraw proposed Reliability Standard MOD-001-2 and
requests that the Commission approve the retirement of the MOD A Reliability Standards in this
proceeding.
Reliability Standard MOD-020-0
Procedural History
Reliability Standard MOD-020-0 – Providing Interruptible Demands and Direct Control
22

Load Management Data to System Operators and Reliability Coordinators was approved by the
Commission in Order No. 693, issued in 2007. 50 As originally written, the standard was applicable
to Load-Serving Entities, Transmission Planners, and Resource Planners. In 2015, the Commission
approved the removal of the Load-Serving Entity from the NERC Compliance Registry. 51
Justification for Retirement
The purpose of Reliability Standard MOD-020-0 is to ensure that past and forecasted
demand data are available for validation of past events and future system assessments. Reliability
Standard MOD-020-0 consists of a single requirement which provides as follows:
R1.

The Load-Serving Entity, Transmission Planner, and Resource
Planner shall each make known its amount of interruptible
demands and Direct Control Load Management (DCLM) to
Transmission Operators, Balancing Authorities, and Reliability
Coordinators on request within 30 calendar days.

NERC proposes to retire Reliability Standard MOD-020-0 on the basis that it provides
little, if any, benefit to reliability and is duplicative to other mechanisms for obtaining the
information required be provided by the standard.
Reliability Standard MOD-020-0 requires information on Interruptible Demands and
Direct Control Load Management to be provided within 30 calendar days of a request. As such,
information obtained under this standard may properly be regarded as a resource for the long-term
planning and operations planning time horizons, but not for the Real-time operations time horizon
or for day-ahead studies. As such, this standard does not provide useful information for
Transmission Operators and Reliability Coordinators, who must plan and operate the BPS within
System Operating Limits and Interconnection Reliability Operating Limits under the TOP and IRO
Reliability Standards, nor does it provide useful information to the Balancing Authority, who must

23

maintain generation-Load-interchange balance in real time. Even if such information was available
more quickly than 30 days, the amount of interruptible demands and DCLM at the Transmission
Planner and Resource Planner level is not sufficiently granular to be of locational benefit to
Balancing Authorities, Transmission Operators, or Reliability Coordinators to assist them in
operating in Real-time or planning for next-day operations.
To the extent that interruptible demand and DCLM information is useful to Transmission
Operators, Reliability Coordinators, and Balancing Authorities as a longer-term resource, it may
be obtained from the NERC Demand Response Availability System (“DADS”). Beginning in
2011, NERC began the mandatory collection of information on demand response programs and
events where demand response was used under its authority provided in Section 1600 of the NERC
Rules of Procedure. 52
For these reasons, NERC has determined that Reliability Standard MOD-020-0 provides
little, if any, benefit to reliability and should be retired.
JUSTIFCATION FOR APPROVAL – PROPOSED RELIABILITY STANDARDS
In this petition, NERC proposes for Commission approval seven revised Reliability
Standards in which requirements from the currently effective Reliability Standards are proposed
to be retired:
•

FAC-008-4 – Facility Ratings

•

INT-006-5 – Evaluation of Interchange Transactions

•

INT-009-3 – Implementation of Interchange

•

PRC-004-6 – Protection System Misoperation Identification and Correction

at https://www.nerc.com/pa/RAPA/dads/Pages/default.aspx.

24

For the reasons set forth in this section, none of the requirements proposed for retirement
in the proposed Reliability Standards are necessary for reliability. As shown in the redlines
included in Exhibit A, for each instance in which NERC has proposed to retire a Reliability
Standard requirement, NERC has struck the requirement in its entirety and replaced the text with
the word “Reserved.” Corresponding revisions have also been made to the VRFs, VSLs, measures,
and, where present, the supplemental material included as information.
The proposed Reliability Standards continue to meet the Commission’s criteria for
approval in Order No. 672 and are just, reasonable, not unduly discriminatory, and in the public
interest. NERC respectfully requests that the Commission approve these Reliability Standards, to
become effective in accordance with the proposed implementation plan discussed in Section VI.
Reliability Standard FAC-008-4
Procedural History
Reliability Standard FAC-008-3 – Facility Ratings was approved by the Commission in
2011. 53 The standard was developed in response to Commission directives from Order No. 693 to
modify the FAC-008 standard to require entities to: (i) document underlying assumptions and
methods used to determine normal and emergency facility ratings; (ii) develop facility ratings
consistent with industry standards developed through an open, transparent, and validated process;
and (iii) for each facility, identify the limiting component and, for critical facilities, the resulting
increase in rating if that component is no longer limiting. 54 In 2013, the Commission approved the
retirement of Requirements R4 and R5 following NERC’s “paragraph 81” initiative. 55

Order No. 788 at P 17. In proposed Reliability Standard FAC-008-4, NERC has struck the text of these
requirements and replaced them with the word “Reserved.”
54

25

Justification for Approval
The purpose of proposed Reliability Standard FAC-008-4, which remains unchanged from
the currently effective version of the standard, is to “to ensure that Facility Ratings used in the
reliable planning and operation of the Bulk Electric System (BES) are determined based on
technically sound principles. A Facility Rating is essential for the determination of System
Operating Limits.”
In proposed Reliability Standard FAC-008-4, NERC proposes to retire Requirements R7
and R8 of the currently effective standard because these requirements are redundant to those in
other Reliability Standards and therefore are not needed for reliability.
Reliability Standard FAC-008-3 Requirements R7 and R8 require Generator Owners and
Transmission Owners to provide certain information to requesting Reliability Coordinator(s),
Planning Coordinator(s), Transmission Planner(s), Transmission Owner(s), and Transmission
Operator(s) regarding their Facilities, as follows:
R7.

Each Generator Owner shall provide Facility Ratings (for its solely
and jointly owned Facilities that are existing Facilities, new
Facilities, modifications to existing Facilities and re-ratings of
existing Facilities) to its associated Reliability Coordinator(s),
Planning Coordinator(s), Transmission Planner(s), Transmission
Owner(s) and Transmission Operator(s) as scheduled by such
requesting entities.

R8.

Each Transmission Owner (and each Generator Owner subject to
Requirement R2) shall provide requested information as specified
below (for its solely and jointly owned Facilities that are existing
Facilities, new Facilities, modifications to existing Facilities and reratings of existing Facilities) to its associated Reliability
Coordinator(s), Planning Coordinator(s), Transmission Planner(s),
Transmission Owner(s) and Transmission Operator(s):
8.1.

As scheduled by the requesting entities:
8.1.1. Facility Ratings
8.1.2. Identity of the most limiting equipment of the

26

Facilities
8.2.

Within 30 calendar days (or a later date if specified by the
requester), for any requested Facility with a Thermal Rating
that limits the use of Facilities under the requester’s
authority by causing any of the following: 1) An
Interconnection Reliability Operating Limit, 2) A limitation
of Total Transfer Capability, 3) An impediment to generator
deliverability, or 4) An impediment to service to a major
load center:
8.2.1. Identity of the existing next most limiting equipment
of the Facility
8.2.2. The Thermal Rating for the next most limiting
equipment identified in Requirement R8, Part 8.2.1.

In summary, Requirement R7 provides that each Generator Owner shall provide Facility
Ratings as scheduled by the requesting entities. Requirement R8 provides that Transmission
Owners and applicable Generator Owners shall: (i) provide requesting entities with the Facility
Rating and the identity of the most limiting equipment of a Facility to requesting entities
(Requirement R8 Part 8.1); and (ii) for certain Facilities, provide the identity of the next most
limiting equipment of a Facility as well as the thermal rating of that equipment (Requirement R8
Part 8.2).
In the years since Reliability Standard FAC-008-3 was developed, NERC has developed
other Reliability Standards that render the data provision obligations of Requirements R7 and R8
redundant. Specifically, Reliability Standards MOD-032-1, IRO-010-2, and TOP-003-3 contain
provisions to help ensure that the relevant entities have the data they need from Generator Owners
and Transmission Owners for operations and planning.
Requirement R1 of Reliability Standard MOD-032-1 – Data for Power System Modeling
and Analysis requires the Planning Coordinator and Transmission Planner to develop modeling
data requirements and reporting procedures including the data listed in Attachment 1 to the

27

standard. This data would include information on power capabilities and Facility Ratings.56
Requirement R2 requires the Generator Owner and Transmission Owner to provide the requested
information.
Requirement R1 of Reliability Standard IRO-010-2 – Reliability Coordinator Data
Specification and Collection requires the Reliability Coordinator to maintain a documented
specification for the data necessary to perform its Operational Planning Analyses, Real-time
monitoring, and Real-time Assessments. This data necessarily includes Facility Ratings as inputs
to System Operating Limit monitoring. Requirement R3 requires the Transmission Owner and
Generator Owner to provide requested data. Similarly, Requirement R1 of Reliability Standard
TOP-003-3 – Operational Reliability Data requires the Transmission Operator to maintain a
documented data specification (Requirement R1) and for the Transmission Owner and Generator
Owner to provide the requested data (Requirement R5).
As Reliability Standard FAC-008-3 Requirements R7 and R8 are now redundant to other
more robust Reliability Standards and are no longer needed for reliability, NERC proposes to retire
these Requirements in proposed Reliability Standard FAC-008-4. The retirement of these
Requirements would not have an adverse impact on reliability and is in the public interest.
Reliability Standard INT-006-5
Procedural History and Purpose
Reliability Standard INT-006-4 – Evaluation of Interchange Transactions was approved by
the Commission in 2014.57 NERC last revised the standard as part of a larger project to revise and
consolidate the INT family of Reliability Standards.

Justification
The purpose of proposed Reliability Standard INT-006-5, which remains unchanged from
the currently effective version of the standard, is “to ensure that responsible entities conduct a
reliability assessment of each Arranged Interchange before it is implemented.”
In proposed Reliability Standard INT-006-5, NERC proposes to retire Requirement R3 Part
3.1, Requirement R4, and Requirement R5 of the currently effective standard on the basis that
these requirements provide little, if any, benefit or protection to the reliable operation of the BPS.
Each of these requirements is addressed in turn below.
Requirement R3 Part 3.1
Reliability Standard INT-006-4 Requirement R3 requires that the Source Balancing
Authority and the Sink Balancing Authority receiving a Reliability Adjustment Arranged
Interchange approve or deny it prior to the expiration of time provided in Attachment 1, Column
B to the standard. Requirement R3 Part 3.1 provides as follows:
3.1.

If a Balancing Authority denies a Reliability Adjustment
Arranged Interchange, the Balancing Authority must
communicate that fact to its Reliability Coordinator no more
than 10 minutes after the denial.

NERC has determined, through its experience implementing the standard, that there is no
substantive benefit to reliability by requiring that the Reliability Coordinator be notified when a
Reliability Adjustment Arranged Interchange has been denied. Therefore, NERC proposes to retire
this requirement part on that basis.
Requirement R4
Reliability Standard INT-006-4 Requirement R4 requires each Sink Balancing Authority
to confirm that none of the listed conditions exist prior to transitioning an Arranged Interchange
to Confirmed Interchange. This requirement reads as follows:

29

R4.

Each Sink Balancing Authority shall confirm that none of the
following conditions exist prior to transitioning an Arranged
Interchange to Confirmed Interchange:
•

It is a Reliability Adjustment Arranged Interchange, the time period
specified in Attachment 1, Column B has elapsed, and the Source
Balancing Authority or the Sink Balancing Authority associated
with the Arranged Interchange has not communicated its approval
of the transition.

•

It is not a Reliability Adjustment Arranged Interchange, the time
period specified in Attachment 1, Column B, has elapsed, and not
all Balancing Authorities and Transmission Service Providers
associated with the Arranged Interchange have communicated their
approval of the transition.

•

It is not a Reliability Adjustment Arranged Interchange, the time
period specified in Attachment 1, Column B, has elapsed, and any
entity associated with the Arranged Interchange has communicated
its denial of the transition.

NERC has determined that this requirement provides little, if any, benefit to reliability and
should be retired. Presently, the NAESB Electronic Tagging Functional Specification addresses
the conditions that must exist for an Arranged Interchange to transition to Confirmed Interchange.
As the substance of this requirement relates to commercial or business practices, any such
confirmation would be better accomplished through the Balancing Authority’s e-Tag Authority
Service rather than a mandatory Reliability Standard requirement.
Requirement R5
Reliability Standard INT-006-4 Requirement R5 provides that the Sink Balancing
Authority shall notify certain entities within a set period of time when an Arranged Interchange is
transitioned to Confirmed Interchange. This requirement provides as follows:
R5.

For each Arranged Interchange that is transitioned to Confirmed
Interchange, the Sink Balancing Authority shall notify the following
entities of the on-time Confirmed Interchange such that the
notification is delivered in time to be incorporated into scheduling
systems prior to ramp start as specified in Attachment 1, Column D:

30

5.1. The Source Balancing Authority,
5.2. Each Intermediate Balancing Authority,
5.3. Each Reliability Coordinator associated with each Balancing
Authority included in the Arranged Interchange,
5.4. Each Transmission Service Provider included in the Arranged
Interchange, and
5.5. Each Purchasing Selling Entity included in the Arranged
Interchange.
NERC has determined that this requirement provides little, if any, benefit to reliability and
should be retired. Presently, the NAESB Electronic Tagging Functional Specification addresses
who must be notified when the transition to Confirmed Interchange occurs. As the substance of
this requirement relates to commercial or business practices, any such notifications would be better
accomplished through the Balancing Authority’s e-Tag Authority Service rather than a mandatory
Reliability Standard requirement. The retirement of this requirement would not have an adverse
impact on reliability and is in the public interest.
Reliability Standard INT-009-3
Procedural History and Purpose
Reliability Standard INT-009-2.1 – Implementation of Interchange was approved by the
Commission in 2014. 58 NERC last revised the standard as part of a larger project to revise and
consolidate the INT family of Reliability Standards.
Justification
The purpose of proposed Reliability Standard INT-009-3, which remains unchanged from
the currently effective version of the standard, is “to ensure that Balancing Authorities implement
the Interchange as agreed upon in the Interchange confirmation process.”
In proposed Reliability Standard INT-009-3, NERC proposes to revise Requirement R1 to

58

N. Am. Elec. Reliability Corp., Docket No. RD14-4-000 (June 30, 2014) (delegated letter order). The
Commission approved errata version INT-009-2.1 on Nov. 26, 2014 by delegated letter order in the same proceeding.

31

delete the reference to Reliability Standard INT-010, consistent with NERC’s proposal to retire
that Reliability Standard in its entirety (see Section IV.C). NERC also proposes to retire
Requirement R2 because it is redundant to Reliability Standard BAL-005-1 Requirement R7.
Reliability Standard INT-009-2.1 Requirement R2 provides as follows:
R2.

The Attaining Balancing Authority and the Native Balancing
Authority shall use a dynamic value emanating from an agreed upon
common source to account for the Pseudo-Tie in the Actual Net
Interchange (NIA) term of their respective control ACE (or alternate
control process).

Following the development of Reliability Standard INT-009-2.1, NERC developed, and
the Commission approved, Reliability Standard BAL-005-1 – Balancing Authority Control. 59 The
standard became effective in the United States on January 1, 2019. Reliability Standard BAL-0051 Requirement R7 provides that each Balancing Authority shall ensure that each Pseudo-Tie with
an Adjacent Balancing Authority is equipped with: (i) a common source to provide information to
both Balancing Authorities for the scan rate values in the calculation of Reporting Ace (Part 7.1);
and (ii) a time synchronized common source to determine hourly megawatt-hour values agreedupon to aid in the identification and mitigation of errors (Part 7.2).
As Reliability Standard BAL-005-1 Requirement R7 now addresses the same reliability
goal, NERC determined that it is appropriate to retire Requirement R2 in proposed Reliability
Standard INT-009-3. The retirement of this requirement would not have an adverse impact on
reliability and is in the public interest.

Reliability Standard PRC-004-6
Procedural History and Purpose
In 2015, the Commission approved several versions of the PRC-004 Reliability Standard,
including substantive revisions to the requirements in version PRC-004-3 60 and subsequent
revisions to the applicability section and Violation Risk Factors. The currently effective version is
Reliability Standard PRC-004-5(i). 61
Justification
The purpose of proposed Reliability Standard PRC-004-6, which remains unchanged from
the currently effective version of the standard, is to “identify and correct the causes of
Misoperations of Protection Systems for Bulk Electric System (BES) Elements.” In proposed
Reliability Standard PRC-004-6, NERC proposes to retire Requirement R4 of the currently
effective standard because the requirement provides little, if any, benefit or protection to the
reliable operation of the BPS.
Currently effective Reliability Standard PRC-004-5(i) consists of six requirements for
identifying and analyzing Protection System Misoperations and developing Corrective Action
Plans to address underlying causes. Requirement R4 requires each applicable entity that has not
yet determined the cause of a Misoperation to perform investigative actions as follows:
R4.

Each Transmission Owner, Generator Owner, and Distribution
Provider that has not determined the cause(s) of a Misoperation, for
a Misoperation identified in accordance with Requirement R1 or R3,
shall perform investigative action(s) to determine the cause(s) of the
Misoperation at least once every two full calendar quarters after the
Misoperation was first identified, until one of the following
completes the investigation:

N. Am. Elec. Reliability Corp., Docket No. RD15-5-000 (Nov. 19, 2015) (delegated letter order) (approving
PRC-004-5) and N. Am. Elec. Reliability Corp., Docket Nos. RD14-14-001, RD15-3-001, and RD15-5-001 (Dec. 4,
2015) (approving revisions to VRFs and VSLs).

The identification of the cause(s) of the Misoperation; or
A declaration that no cause was identified.

While originally intended to promote due diligence in identifying the causes of
Misoperations, the activities associated with Requirement R4 have in practice consisted of
developing tracking documents to show that investigative actions were performed at the required
periodicity. Upon further review of this requirement, NERC has determined that it does not
necessarily promote effective or efficient investigation practices. In some cases, an entity may
need additional time beyond two calendar quarters to conduct a diligent investigation, particularly
if equipment outages are necessary. Moreover, if an entity is unable to determine the cause of a
Misoperation, further investigation(s) every two calendar quarters using the same event data are
unlikely to lead to the identification of the cause. For these reasons, NERC has determined that it
would be more effective and efficient to have entities investigate the causes of Misoperations
according to their own internal control policies and procedures, rather than in accordance with a
mandatory Reliability Standard requirement that requires investigative actions be performed on a
specific, recurring, and inflexible timeframe.
Based on these considerations, NERC has determined that Reliability Standard PRC-0045(i) Requirement R4 provides little, if any, benefit or protection to the reliable operation of the
BPS. Therefore, NERC proposes to retire Requirement R4 in proposed Reliability Standard PRC004-6. The retirement of this requirement would not have an adverse impact on reliability and is
in the public interest.
Enforceability of the Proposed Reliability Standards
The proposed Reliability Standards contain Violation Risk Factors (“VRFs”) and Violation
Severity Levels (“VSLs”) for each of the requirements. The VRFs and VSLs provide guidance on
the way that NERC will enforce the requirements of the proposed Reliability Standards. The VRFs

34

and VSLs are substantively unchanged from currently effective versions of the Reliability
Standards, reflecting only those revisions necessary to effectuate the proposed requirement
retirements. As such, they continue to comport with NERC and Commission guidelines related to
their assignment.
In addition, the proposed Reliability Standards also include measures that support the
requirements by clearly identifying what is required and how the requirement will be enforced.
The measures help ensure that the requirements will be enforced in a clear, consistent, and nonpreferential manner and without prejudice to any party. The measures are substantively unchanged
from currently enforceable versions of the Reliability Standards, reflecting only those revisions
necessary to effectuate the proposed requirement retirements.
EFFECTIVE DATE
NERC respectfully requests that the Commission approve the implementation plan
attached to this petition as Exhibit B, as it relates to the Reliability Standard proposals addressed
in this petition. The proposed implementation plan provides that, for Reliability Standards that are
proposed to be retired in their entirety (i.e. no new standard version is proposed), the retirement
would become effective immediately upon regulatory approval. For the proposed revised
Reliability Standards, the revised standards would become effective on the first day of the first
calendar quarter that is three months after applicable regulatory approval. The currently effective
versions of those Reliability Standards would be retired immediately prior to the effective date of
the revised Reliability Standards. This implementation timeline reflects consideration that entities
may need time to update their internal systems and documentation to reflect the new Reliability
Standard version numbers.
