[Docket No. RM10-6-000; Order No. 754]

Interpretation of Transmission Planning Reliability Standard

AGENCY: Federal Energy Regulatory Commission, Energy.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: On November 17, 2009, the North American Electric Reliability 
Corporation (NERC) submitted a petition requesting approval of NERC's 
interpretation of Requirement R1.3.10 of Commission-approved 
transmission planning Reliability Standard TPL-002-0 (System 
Performance Following Loss of a Single Bulk Electric System Element). 
In a March 2010 Notice of Proposed Rulemaking (NOPR), the Commission 
proposed to reject NERC's proposed interpretation, and instead proposed 
an alternative interpretation of Requirement R1.3.10 of Reliability 
Standard TPL-002-0. As a result of the comments received in response to 
the proposal, the Commission declines to adopt the NOPR proposal and 
approves NERC's proposed interpretation. In addition, as proposed by 
several commenters, the Commission directs NERC and Commission staff to 
initiate a process to identify any reliability issues, as discussed 
below.

DATES: Effective Date: This rule will become effective October 24, 
2011.

    1. On November 17, 2009, the North American Electric Reliability 
Corporation (NERC) submitted a petition requesting approval of NERC's 
interpretation of Requirement R1.3.10 of Commission-approved 
transmission planning Reliability Standard TPL-002-0 (System 
Performance Following Loss of a Single Bulk Electric System Element). 
In a March 2010 Notice of Proposed Rulemaking (NOPR),\1\ the Commission 
proposed to reject NERC's proposed interpretation, and instead proposed 
an alternative interpretation of Requirement R1.3.10 of Reliability 
Standard TPL-002-0. As a result of the comments received in response to 
the proposal, the Commission declines to adopt the NOPR proposal and 
approves NERC's proposed interpretation of Requirement R1.3.10 of 
Reliability Standard TPL-002-0. In addition, as proposed by several 
commenters, the Commission directs NERC and Commission staff to 
initiate a process to identify any reliability issues, as discussed 
below.

I. Background

    2. Section 215 of the Federal Power Act (FPA) requires a 
Commission-certified Electric Reliability Organization (ERO) to develop 
mandatory and enforceable Reliability Standards, which are subject to 
Commission review and approval.\2\ Specifically, the Commission may 
approve, by rule or order, a proposed Reliability Standard or 
modification to a Reliability Standard if it determines that the 
Standard is just, reasonable, not unduly discriminatory or 
preferential, and in the public interest.\3\ Once approved, the 
Reliability Standards may be enforced by the ERO, subject to Commission 
oversight, or by the Commission independently.\4\

[[Page 58717]]

    3. Pursuant to section 215 of the FPA, the Commission established a 
process to select and certify an ERO,\5\ and subsequently certified 
NERC.\6\ On April 4, 2006, NERC submitted to the Commission a petition 
seeking approval of 107 proposed Reliability Standards. On March 16, 
2007, the Commission issued a final rule, Order No. 693,\7\ approving 
83 of the 107 Reliability Standards, including transmission planning 
Reliability Standards TPL-001-0 through TPL-004-0. In addition, 
pursuant to section 215(d)(5) of the FPA,\8\ the Commission directed 
NERC to develop modifications to 56 of the 83 approved Reliability 
Standards, including TPL-002-0.\9\

    4. NERC's Rules of Procedure provide that a person that is 
``directly and materially affected'' by Bulk-Power System reliability 
may request an interpretation of a Reliability Standard.\10\ In 
response, the ERO will assemble a team with relevant expertise to 
address the requested interpretation and also form a ballot pool. 
NERC's Rules of Procedure provide that, within 45 days, the team will 
draft an interpretation of the reliability standard and submit it to 
the ballot pool. If approved by the ballot pool and subsequently by the 
NERC Board of Trustees, the interpretation is appended to the 
Reliability Standard and filed with the applicable regulatory 
authorities for approval.

---------------------------------------------------------------------------

II. Transmission Planning Reliability Standards

    5. Each of the TPL Reliability Standards, TPL-001-0 through TPL-
004-0, requires the planning authorities and transmission planners 
(planner) to provide a ``valid assessment'' that would ``ensure that 
reliable systems are developed that meet specified performance 
requirements'' both in the near-term (years one through five) and in 
the longer-term (years six through ten, or as needed). For each of 
these TPL Reliability Standards, entities must adequately assess a 
range of operating conditions on their systems and plan to meet certain 
performance criteria that the TPL Reliability Standards specify for 
each of four classes of contingencies.\11\ The principles that planners 
must apply to the design of the assessment and of the supporting 
studies are set forth in the Requirements of the specific TPL 
Reliability Standard.
---------------------------------------------------------------------------

    \11\ Reliability Standards TPL-001-0 through TPL-004-0 each 
includes the same Table I, titled ``Transmission System Standards--
Normal and Emergency Conditions,'' which identifies the classes of 
contingencies as Category A through Category D. Reliability Standard 
TPL-002-0 addresses Category B contingencies.
---------------------------------------------------------------------------

    6. Table I, which is incorporated into each of the TPL Reliability 
Standards, sets forth the different types of contingencies that 
planners must study in conjunction with critical system conditions. The 
performance that must be met before and after experiencing those 
contingencies is also defined in the Table I, including reliably 
meeting all projected customer demand and firm transfers for Category B 
contingencies.
    7. Requirement R1 of Reliability Standard TPL-002-0 states:

    R1. The Planning Authority and Transmission Planner shall each 
demonstrate through a valid assessment that its portion of the 
interconnected transmission system is planned such that the Network 
can be operated to supply projected customer demands and projected 
Firm (non-recallable reserved) Transmission Services, at all demand 
levels over the range of forecast system demands, under the 
contingency conditions as defined in Category B.[\12\] To be valid, 
the Planning Authority and Transmission Planner assessments shall: * 
* *.

    \12\ Category B contingencies are defined in Table I of the 
Reliability Standard.
---------------------------------------------------------------------------

    8. Requirement R1 proceeds with sub-Requirements R1.1 through R1.5, 
which provide the criteria that must be met to qualify the assessment 
directed by Requirement R1 as valid. In particular, Requirement R1.3 
mandates that the assessment shall

    [b]e supported by a current or past study and/or system 
simulation testing that addresses each of the following categories, 
showing system performance following Category B. The specific 
elements selected (from each of the following categories) for 
inclusion in these studies and simulations shall be acceptable to 
the associated Regional Reliability Organization(s).

    Further, Requirement R1.3.10 requires the planner to

    [i]nclude the effects of existing and planned protection 
systems, including any backup or redundant systems.

III. NERC Proposed Interpretation

    9. In the NERC Petition, NERC explained that it received a request 
from PacifiCorp for an interpretation of Reliability Standard TPL-002-
0, Requirement R1.3.10, addressing three specific questions. The 
PacifiCorp questions and NERC interpretations were as follows:

    Question 1: Does TPL-002-0 R1.3.10 require that all elements 
that are expected to be removed from service through normal 
operation of the protection systems be removed in simulations?
    Response 1: TPL-002-0 requires that System studies or 
simulations be made to assess the impact of single Contingency 
operation with Normal Clearing. TPL-002-0, R1.3.10 does require that 
all elements expected to be removed from service through normal 
operations of the Protection Systems be removed in simulations.
    Question 2: Is a Category B disturbance limited to faults with 
[N]ormal [C]learing where the protection system operates as designed 
in the time expected with proper functioning of the protection 
system(s) or do Category B disturbances extend to protection system 
misoperations and failures?
    Response 2: This standard does not require an assessment of the 
Transmission System performance due to a Protection System failure 
or Protection System misoperation. Protection System failure or 
Protection System misoperation is addressed in TPL-003-0--System 
Performance following Loss of Two or More Bulk Electric System 
Elements (Category C) and TPL-004-0--System Performance Following 
Extreme Events Resulting in the Loss of Two or More Bulk Electric 
System (BES) Elements (Category D).
    Question 3: Does TPL-002-0, R1.3.10 require that planning for 
Category B [C]ontingencies assume a [C]ontingency that results in 
something other than a [N]ormal [C]learing event even though the 
TPL-002-0 Table I--Category B matrix uses the phrase ``SLG or 3-
Phase Fault, with Normal Clearing?''
    Response 3: TPL-002-0, R1.3.10 does not require simulating 
anything other than Normal Clearing when assessing the impact of a 
Single Line Ground (SLG) or 3-Phase (3[Oslash]) Fault on the 
performance of the Transmission System.\13\
---------------------------------------------------------------------------

    \13\ NERC Petition at 10. In support for its request for an 
interpretation, PacifiCorp states that ``[i]f TPL-002-0, R1.3.10 
requires that planning for Category B Contingencies must assume 
failure or misoperation of all existing and planned protection 
systems, protection system failures previously identified as 
Category C [[Oslash]] Contingencies or Category D [[Oslash]] 
Contingencies would now become Category B Contingencies * * *.'' Id. 
at Appendix A at 1-2.
---------------------------------------------------------------------------

    10. In support of its request for approval, NERC stated that the 
proposed interpretation directly supports the reliability purpose of 
TPL-002-0 because it clarifies what is required for the ``System 
simulations'' cited in the main requirement without expanding

[[Page 58718]]

the reach of the standard.\14\ NERC maintained that the proposed 
interpretation clearly identifies what needs to be done--that all 
elements expected to be removed from service through normal operation 
of the protection system must be removed in simulations and that only 
normal clearing is required in the simulations. NERC stated that the 
proposed interpretation clearly distinguishes that misoperations and 
failures of the protection system are not part of Reliability Standard 
TPL-002-0, but are addressed in other standards. NERC stated that the 
interpretation will result in ensuring that an adequate level of 
reliability for the Bulk-Power System will be achieved and maintained 
by providing clarity and certainty in support of the objective.
---------------------------------------------------------------------------

    \14\ Id. at 11.
---------------------------------------------------------------------------

IV. Commission NOPR

    11. The Commission proposed to reject NERC's proposed 
interpretation and proposed an alternative interpretation. The 
Commission's proposed interpretation would have required modeling of 
the non-operation of non-redundant primary protection systems to be in 
compliance with Requirement R1.3.10 of Reliability Standard TPL-002-0. 
In the NOPR, the Commission stated that a planner would perform an 
assessment of its portion of the interconnected transmission system 
through computer modeling and simulations, in which the planner first 
creates base cases. Using these base cases as a starting point, the 
planner then assesses the performance of the system and tests the base 
cases by subjecting them to various Category B Contingencies outlined 
in Table I with normal clearing. The Commission's proposed 
interpretation would have found that Requirement R1.3.10 of TPL-002-0 
requires planners to study, in their system assessments, the non-
operation of non-redundant primary protection systems in order to 
ascertain whether and how reliance on the as-designed backup or 
redundant protection systems affects reliability.\15\
---------------------------------------------------------------------------

    \15\ Interpretation of Transmission Planning Reliability 
Standards, FERC Stats. & Regs. ] 32,655, at P 15 (2010).
---------------------------------------------------------------------------

    12. The Commission proposed that its interpretation of R1.3.10 of 
Reliability Standard TPL-002-0 would apply prospectively from the 
effective date of any Final Rule and no entity will be subject to 
financial penalties for having operated in a manner inconsistent with 
this proposed interpretation prior to the effective date of any Final 
Rule.

V. Comments

    13. Twenty-seven entities provided comments on the Commission's 
proposed interpretation.\16\ Almost uniformly, comments support NERC's 
proposed interpretation.\17\ In general, commenters \18\ state that the 
non-operation of a primary protection system is not studied under TPL-
002-0, but rather under TPL-003-0 and TPL-004-0 as an unplanned event 
with delayed clearing.\19\ Commenters contend that only planned 
protection system outages (maintenance outages) should be addressed 
under TPL-002-0.\20\ In addition, commenters assert that the 
Commission's interpretation would require the installation of fully 
redundant protection systems at an estimated cost of $24 billion and 
require significant construction efforts spanning 10 to 20 years.\21\ 
Commenters contend that TPL-002-0 relates to Normal Clearing and not 
Delayed Clearing in which a protection system failure has occurred or 
fails to operate.
---------------------------------------------------------------------------

    \16\ A list of commenters is provided in Appendix 1.
    \17\ Commenters including NERC, Trade Associations (Edison 
Electric Institute, American Public Power Association, National 
Rural Electric Cooperative Association, Electric Power Supply 
Association, Transmission Access Policy Study Group, and Canadian 
Electricity Association), Florida Reliability Coordinating Council 
and others indicate support for NERC's interpretation of Requirement 
R1.3.10 of TPL-002-0. In contrast, the International Transmission 
Companies (ITC) commented that the Commission's proposal 
``establishes an additional level of good utility practice'' and 
``is a reasonable and rational approach to evaluate system 
consequences, under Requirement R1.3.10 of TPL-002-0, regarding 
element outages and clearing times associated with non-operation of 
the primary protection system.'' However, given the corrective 
actions that would be required to comply with the Commission's 
proposal, ITC requests that the Commission allow an appropriate 
amount of time for compliance.
    \18\ See, e.g., NERC comments at 7-8; Trade Association Comments 
at 19-23.
    \19\ Planned outages are modeled as one of the base case 
conditions (categories) and studied to achieve the performance 
requirements of Category B (single contingencies), Table I. 
Protection system failures are addressed by performance requirements 
of Category C (two or more contingencies) and misoperations are 
addressed by Category D (extreme events).
    \20\ Requirement R.1.3.12 of TPL-002-0 requires the planner to 
consider the planned (including maintenance) outage of protection 
systems at demand levels for which such outages are performed.
    \21\ See Trade Associations comments at 31-34.
---------------------------------------------------------------------------

    14. NERC explains that the pre-2007 voluntary transmission planning 
standard was broken into four mandatory Version 0 Standards linked by 
the performance categories of Table I. Thus, according to NERC, some 
continuity was lost and, as a result, sub-requirements such as 
Requirement R1.3.10 that appear in TPL-002-0 through TPL-004-0 have 
very limited applicability in the context of TPL-002-0. NERC explains 
that Requirement R1.3.10 of TPL-002-0 is a valid requirement for 
judging system performance, but only in those cases where the system is 
being studied to determine its ability to perform when a given primary 
protection system or one of its components is out of service for 
maintenance (Requirement R1.3.12).

A. Supplemental Comments

    15. The Trade Associations submitted supplemental comments, with 
additional comments in support filed by NERC. The Trade Associations 
reiterate their request that the Commission approve, without change, 
NERC's proposed interpretation of Reliability Standard TPL-002-0 
Requirement R1.3.10. The Trade Associations also state that, based on 
outreach meetings with Commission staff, there may be a system 
protection issue that merits further exploration by technical experts. 
Thus, the Trade Associations suggest that the Commission take the 
following two actions. First, instruct Commission Reliability Staff to 
meet with NERC and its appropriate subject matter experts to: (a) 
Explore Staff's concerns and identify whether there is a further system 
protection issue warranting additional actions, and (b) if so, define 
the issue's scope and assess its importance. The Trade Associations 
state such exchange of views among technical experts would be intended 
to facilitate the subject matter experts' ability to recommend 
appropriate actions within NERC. Second, direct NERC to submit an 
informational filing within six months to explain its view as to 
whether there is a further system protection issue that needs to be 
addressed and if so, what forum and process should be used to address 
that issue and what priority it should be accorded relative to other 
reliability initiatives planned by NERC.\22\
---------------------------------------------------------------------------

    \22\ Trade Associations Supplemental Comments at 3 (footnote 
omitted).
---------------------------------------------------------------------------

    16. NERC supports the Trade Associations' proposal to give NERC, 
Commission staff, and technical experts the opportunity to further 
examine whether there may be a potential system protection issue that 
needs to be addressed. NERC states that it would make an informational 
filing with the Commission regarding whether there is a further system 
protection issue that needs to be addressed and if so, what forum and 
process should be used to address that issue and what priority it 
should be accorded relative to other reliability initiatives planned by 
NERC.

[[Page 58719]]

    17. NERC requests that the Commission approve the proposed 
interpretation of Reliability Standard TPL-002-0 Requirement R1.3.10, 
as filed.

VI. Discussion

    18. In the NOPR, the Commission proposed to find that Reliability 
Standard TPL-002-0, Requirement R1.3.10 requires the study of the non-
operation of non-redundant primary protection systems. Based on the 
comments received, the Commission accepts NERC's interpretation of TPL-
002-0, Requirement R1.3.10, that finds that the requirement does not 
require the study of non-operation of non-redundant primary protection 
systems. Because we find NERC's proposed interpretation to be just and 
reasonable, we, therefore, decline to adopt the NOPR proposal.
    19. We agree with the Trade Associations that there may be a system 
protection issue that merits further exploration by technical experts. 
The comments received in response to the Commission's NOPR and 
Commission staff outreach discussions indicate that there may have been 
a misunderstanding that the Commission's proposed interpretation would 
have established a full redundancy requirement for all primary 
protection systems. The Commission clarifies that it did not intend to 
require full redundancy. Rather, the Commission believes that there is 
an issue concerning the study of the non-operation of non-redundant 
primary protection systems; e.g., the study of a single point of 
failure on protection systems. The Commission agrees with commenters 
that this issue does not have to be addressed in TPL-002-0, Requirement 
R1.3.10.
    20. Accordingly, consistent with the supplemental comments of the 
Trade Associations, we direct Commission staff to meet with NERC and 
its appropriate subject matter experts to explore this reliability 
concern, including where it can best be addressed, and identify any 
additional actions necessary to address the matter. Further, we direct 
NERC to make an informational filing within six months of the date of 
the issuance of this Final Rule explaining whether there is a further 
system protection issue that needs to be addressed and, if so, what 
forum and process should be used to address that issue and what 
priority it should be accorded relative to other reliability 
initiatives planned by NERC.\23\
---------------------------------------------------------------------------

    \23\ This filing requirement has been approved by the Office of 
Management and Budget under FERC-725, OMB Control No. 1902-0225. 
This filing does not change the existing burden or reporting 
requirements imposed on NERC under FERC-725.
---------------------------------------------------------------------------

VII. Information Collection Statement

    21. The Office of Management and Budget (OMB) regulations require 
that OMB approve certain reporting and recordkeeping (collections of 
information) imposed by an agency.\24\ The information contained here 
is also subject to review under section 3507(d) of the Paperwork 
Reduction Act of 1995.\25\
---------------------------------------------------------------------------

    \24\ 5 CFR 1320.11.
    \25\ 44 U.S.C. 3507(d).
---------------------------------------------------------------------------

    22. As stated above, the Commission previously approved, in Order 
No. 693, the Reliability Standard that is the subject of the current 
Final Rule. This Final Rule accepts an interpretation of the currently 
approved Reliability Standard and does not change this standard. The 
interpretation of the current Reliability Standard at issue in this 
final rule is not expected to change the reporting burden or the 
information collection requirements. The informational filing required 
of NERC is part of currently active collection FERC-725 and does not 
require additional approval by OMB.\26\
---------------------------------------------------------------------------

    \26\ See supra n. 23.
---------------------------------------------------------------------------

    23. We will submit this final rule to OMB for informational 
purposes only.
    24. Interested persons may obtain information on the reporting 
requirements by contacting the following: Federal Energy Regulatory

VIII. Environmental Analysis

    25. The Commission is required to prepare an Environmental 
Assessment or an Environmental Impact Statement for any action that may 
have a significant adverse effect on the human environment.\27\ The 
Commission has categorically excluded certain actions from this 
requirement as not having a significant effect on the human 
environment. Included in the exclusion are rules that are clarifying, 
corrective, or procedural or that do not substantially change the 
effect of the regulations being amended.\28\ The actions proposed 
herein fall within this categorical exclusion in the Commission's 
regulations.

---------------------------------------------------------------------------

IX. Regulatory Flexibility Act

    26. The Regulatory Flexibility Act of 1980 (RFA) \29\ generally 
requires a description and analysis of final rules that will have 
significant economic impact on a substantial number of small entities. 
The RFA mandates consideration of regulatory alternatives that 
accomplish the stated objectives of a proposed rule and that minimize 
any significant economic impact on a substantial number of small 
entities. The Small Business Administration's (SBA) Office of Size 
Standards develops the numerical definition of a small business.\30\ 
The SBA has established a size standard for electric utilities, stating 
that a firm is small if, including its affiliates, it is primarily 
engaged in the transmission, generation and/or distribution of electric 
energy for sale and its total electric output for the preceding twelve 
months did not exceed four million megawatt hours.\31\ The RFA is not 
implicated by this Final Rule because the interpretation accepted 
herein does not modify the existing burden or reporting requirements. 
With no changes to the Reliability Standard as approved, the Commission 
certifies that this Final Rule will not have a significant economic 
impact on a substantial number of small entities.
