Transmission Planning Reliability Standard TPL-001-5

AGENCY: Federal Energy Regulatory Commission, Department of Energy.

ACTION:  Notice of proposed rulemaking.

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

SUMMARY: The Federal Energy Regulatory Commission (Commission) proposes 
to approve Reliability Standard TPL-001-5 (Transmission System Planning 
Performance Requirements). The North American Electric Reliability 
Corporation (NERC), the Commission-certified Electric Reliability 
Organization, submitted the proposed Reliability Standard for 
Commission approval to address: Reliability issues concerning the study 
of single points of failure of protection systems; and Commission 
directives regarding planned maintenance outages and stability analysis 
for spare equipment strategy. In addition, the Commission proposes to 
direct NERC to modify the Reliability Standards to require corrective 
action plans for protection system single points of failure in 
combination with a three-phase fault if planning studies indicate 
potential cascading.

SUPPLEMENTARY INFORMATION: 
    1. Pursuant to section 215(d)(2) of the Federal Power Act (FPA), 
the Commission proposes to approve Reliability Standard TPL-001-5 
(Transmission System Planning Performance Requirements).\1\ The North 
American Electric Reliability Corporation (NERC), the Commission-
certified Electric Reliability Organization (ERO), submitted proposed 
Reliability Standard TPL-001-5 for Commission approval to address: 
reliability issues concerning the study of single points of failure of 
protection systems discussed in Order No. 754; and directives from 
Order No. 786 regarding planned maintenance outages and stability 
analysis for spare equipment strategy.\2\

Planning Reliability Standards, Order No. 786, 145 FERC ] 61,051, at 
PP 40, 89 (2013).
---------------------------------------------------------------------------

    2. Proposed Reliability Standard TPL-001-5 is one of two 
transmission planning Reliability Standards containing requirements for 
planning authorities and transmission planners to develop studies of 
their portions of the bulk electric system. Proposed Reliability 
Standard TPL-001-5 establishes transmission system planning performance 
requirements within the planning horizon to promote a bulk electric 
system that will operate reliably over a broad spectrum of system 
conditions and following a wide range of probable contingencies. NERC 
states that the revisions in the proposed Reliability Standard are 
intended to enhance requirements for the study of protection system 
single points of failure.\3\
---------------------------------------------------------------------------

    \3\ A protection system ``single point of failure'' refers to a 
non-redundant component of a protection system that, if it failed, 
would affect normal clearing of faults. NERC Petition at 4.
---------------------------------------------------------------------------

    3. Proposed Reliability Standard TPL-001-5 requires each planning 
authority and transmission planner to perform an annual planning 
assessment of its portion of the bulk electric system considering a 
number of system conditions and contingencies. The proposed Reliability 
Standard employs a risk-based approach to the study of contingencies 
and the types of corrective action that are required if the entity's 
system cannot meet the specified performance requirements.\4\ For 
scenarios considered to be more commonplace (i.e., planning events), 
the planning entity must develop a corrective action plan if it 
determines through studies that its system would experience performance 
issues. For the scenarios considered to be less commonplace, but which 
could result in potentially severe impacts such as cascading (i.e., 
extreme events), the planning entity must conduct a comprehensive 
analysis to understand both the potential impacts on its system and the 
types of actions that could reduce or mitigate those impacts.\5\
---------------------------------------------------------------------------

    \4\ NERC defines ``Corrective Action Plan'' as, ``A list of 
actions and an associated timetable for implementation to remedy a 
specific problem.'' Glossary of Terms Used in NERC Reliability 
Standards (May 13, 2019) (NERC Glossary).
    \5\ NERC defines ``Cascading'' as, ``The uncontrolled successive 
loss of System Elements triggered by an incident at any location. 
Cascading results in widespread electric service interruption that 
cannot be restrained from sequentially spreading beyond an area 
predetermined by studies.'' NERC Glossary.
---------------------------------------------------------------------------

    4. Proposed Reliability Standard TPL-001-5 contains revisions to 
both the planning event (Category P5) and extreme events (Stability 
2.a-h)--identified in Table 1 (Steady State and Stability Performance 
Planning Events and Steady State and Stability Performance Extreme 
Events) and the associated footnote 13--to provide for more 
comprehensive study of the potential impacts of protection system 
single points of failure.\6\ Planning entities would be required to 
take action, consistent with currently-effective Reliability Standard 
TPL-001-4 requirements, to address system performance issues identified 
as a result of these studies. Additionally, the proposed Reliability 
Standard addresses the two Commission directives in Order No. 786. 
Accordingly, pursuant to section 215(d)(2) of the FPA, the Commission 
proposes to approve proposed Reliability Standard TPL-001-5 because it 
is responsive to the Commission's directives and improves upon the 
currently-effective Reliability Standard by enhancing requirements for 
the study of protection system single points of failure.
---------------------------------------------------------------------------

    \6\ Proposed Reliability Standard TPL-001-5 includes an expanded 
list of protection system components for single points of failure 
studies. The selected list of components account for: (1) Those 
failed non-redundant components of a protection system that may 
impact one or more protection systems; (2) the duration that faults 
remain energized until delayed fault clearing; and (3) the 
additional system equipment removed from service following fault 
clearing depending on the specific failed non-redundant component of 
a protection system. NERC Petition at 16.
---------------------------------------------------------------------------

    5. Non-redundant protection systems can also misoperate when faced 
with a three-phase fault. Because three-phase faults are more serious 
than single-phase-to-ground faults, the consequences can be more 
severe, including cascading. However, rather than require a corrective 
action plan to address such events, proposed Reliability Standard TPL-
001-5 only requires an evaluation of possible actions designed to 
reduce the likelihood or mitigate their consequences and adverse 
impacts.\7\ NERC has not adequately justified categorizing protection 
system single points of failure in combination with a three-phase fault 
as an ``extreme event'' that only requires study, but not a corrective 
action plan, when there is the potential for cascading. We are not 
persuaded that such events do not necessitate corrective action plans 
because of their alleged rarity, particularly because their potential 
impacts may result in cascading. Thus, pursuant to section 215(d)(5) of 
the FPA, we also propose to direct that NERC develop modifications to 
the Reliability Standards to require corrective action plans for 
protection system single points of failure in combination with three-
phase faults if planning studies indicate potential cascading.\8\

(filed March 15, 2012) (2012 Informational Filing). A three-phase 
fault can originate as a single-line-to-ground (SLG) fault as ``it 
is not uncommon for a SLG fault to evolve to a multi-phase fault.''

I. Background

A. Section 215 and Mandatory Reliability Standards

    6. Section 215 of the FPA requires a Commission-certified ERO to 
develop mandatory and enforceable Reliability Standards, subject to 
Commission review and approval. Reliability Standards may be enforced 
by the ERO, subject to Commission oversight, or by the Commission 
independently.\9\ Pursuant to section 215 of the FPA, the Commission 
established a process to

[[Page 30641]]

select and certify an ERO,\10\ and subsequently certified NERC.\11\

B. Order No. 754

    7. In Order No. 754, which approved an interpretation of 
Reliability Standard TPL-002-0, Requirement R1.3.10, the Commission 
determined that ``there may be a system protection issue that merits 
further exploration by technical experts'' and that there is ``an issue 
concerning the study of the non[hyphen]operation of 
non[hyphen]redundant primary protection systems; e.g., the study of a 
single point of failure on protection systems.'' \12\ To address this 
concern, the Commission directed ``Commission staff to meet with NERC 
and its appropriate subject matter experts to explore the reliability 
concern, including where it can best be addressed, and identify any 
additional actions necessary to address the matter.'' \13\ The 
Commission also directed NERC ``to make an informational filing . . . 
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.'' \14\

    8. In October 2011, Commission staff hosted a technical conference 
on single points of failure, which resulted in four consensus points 
and the following problem statement: ``The group perceives a 
reliability concern regarding the comprehensive assessment of potential 
protection system failures by registered entities. The group agrees on 
the need to study if a [reliability] gap exists regarding the study and 
resolution of a single point of failure on protection systems.'' \15\ 
One outcome of the 2011 technical conference, as described in the 2012 
Informational Filing, was that NERC would issue a data request to aid 
in assessing whether single points of failure in protection systems 
pose a reliability concern. To that end, the NERC Board of Trustees 
subsequently approved a request for data under the NERC Rules of 
Procedure.\16\ Over the next two years, NERC collected data from 
transmission planners. Using the collected data, two subcommittees of 
the NERC Planning Committee, the System Protection and Control 
Subcommittee (SPCS) and the System Analysis and Modeling Subcommittee 
(SAMS), conducted an assessment of protection system single points of 
failure. The study examined in detail the protection systems related to 
nearly 4,000 buses. The findings were presented in a September 2015 
report that concluded that single points of failure on protection 
systems posed a reliability risk that warranted further action.\17\ The 
SPCS/SAMS Report recommended, after considering a variety of 
alternatives, that NERC modify Reliability Standard TPL-001-4 to best 
align with the Order No. 754 directives and maximize reliability of 
protection system performance. In particular, the SPCS/SAMS Report 
recommended that three-phase faults involving protection system 
failures be assessed as an extreme event in Reliability Standard TPL-
001-4, as follows:
---------------------------------------------------------------------------

    \15\ NERC, Order No. 754 Single Point of Failure Technical 
Meeting Notes at 8 (October 24-25, 2011).
    \16\ 2012 NERC Informational Filing at 7 (stating that the data 
request ``is based on an approach that utilizes . . . a three-phase 
(3[Oslash]) fault and assesses simulated system performance against 
performance measures'').

Points of Failure Based on the Section 1600 Data Request at 11 
(September 2015) (SPCS/SAMS Report).

    Additional emphasis in planning studies should be placed on 
assessment of three[hyphen]phase faults involving protection system 
single points of failure. This concern (the study of protection 
system single points of failure) is appropriately addressed as an 
extreme event in TPL-001-4 Part 4.5. From TPL-001-4, Part 4.5: If 
the analysis concludes there is Cascading caused by the occurrence 
of extreme events, an evaluation of possible actions designed to 
reduce the likelihood or mitigate the consequences and adverse 
impacts of the event(s) shall be conducted.\18\

C. Order No. 786

    9. In Order No. 786, the Commission approved the currently-
effective version of the transmission system planning standard, 
Reliability Standard TPL-001-4. In that Order, the Commission also 
issued several directives to NERC, including two relating to future 
standard modifications that are addressed in proposed Reliability 
Standard TPL-001-5. First, the Commission expressed concern that the 
six-month outage duration threshold in Reliability Standard TPL-001-4, 
Requirement R1 could exclude planned maintenance outages of significant 
facilities from future planning assessments.\19\ The Commission 
determined that planned maintenance outages of less than six months in 
duration may result in relevant impacts during one or both of the 
seasonal off-peak periods, and that prudent transmission planning 
should consider maintenance outages at those load levels when planned 
outages are performed to allow for a single element to be taken out of 
service for maintenance without compromising the ability of the system 
to meet demand without loss of load. The Commission further determined 
that a properly planned transmission system should ensure the known, 
planned removal of facilities (i.e., generation, transmission or 
protection system facilities) for maintenance purposes without the loss 
of nonconsequential load or detrimental impacts to system reliability 
such as cascading, voltage instability or uncontrolled islanding. The 
Commission directed NERC to modify the Reliability Standards to address 
this concern.

    \19\ Order No. 786, 145 FERC ] 61,051 at PP 40-45.
---------------------------------------------------------------------------

    10. Second, while stating that NERC had met the Commission's Order 
No. 693 directive to include a spare equipment strategy for steady 
state analysis in Reliability Standard TPL-001-4, the Commission 
determined that a spare equipment strategy for stability analysis was 
not addressed in the standard. The Commission stated that a similar 
spare equipment strategy for stability analysis should exist that 
requires studies to be performed for P0, P1, and P2 categories with the 
conditions that the system is expected to experience during the 
possible unavailability of the long lead time equipment. Rather than 
direct a change at that time, however, the Commission directed NERC to 
consider the issue during the next review cycle of Reliability Standard 
TPL-001-4.\20\
---------------------------------------------------------------------------

    \20\ Id. PP 88-89.
---------------------------------------------------------------------------

D. NERC Petition and Proposed Reliability Standard TPL-001-5

    11. On December 7, 2018, NERC submitted proposed Reliability 
Standard TPL-001-5 for Commission approval.\21\ NERC maintains that the 
proposed Reliability Standard addresses potential system contingencies 
including the protection system single point of failure issue and Order 
No. 786 directives.

[[Page 30642]]

With regard to protection system single points of failure, NERC 
indicates that Table 1 of the proposed Reliability Standard describes 
system performance requirements for a range of potential system 
contingencies required to be evaluated by the planner. Table 1 includes 
three parts: (1) Steady State & Stability Performance Planning Events, 
(2) Steady State & Stability Performance Extreme Events, and (3) Steady 
State & Stability Performance Footnotes. Table 1 describes system 
performance requirements for a range of potential system contingencies 
required to be evaluated by the planner. The table categorizes the 
events as either ``planning events'' or ``extreme events.'' The table 
lists seven contingency planning events (P1 through P7) that require 
steady-state and stability analysis as well as five extreme event 
contingencies: three for steady-state and two for stability. NERC 
asserts that proposed Reliability Standard TPL-001-5 also includes 
certain modifications to better ensure that planning entities are 
performing a more complete analysis of potential protection system 
single points of failure on their systems and taking appropriate action 
to address these concerns. NERC explains that the proposed Reliability 
Standard contains revisions to both the Table 1 planning event 
(Category P5) and extreme events (Stability 2.a-h) and the associated 
footnote 13 to provide for more comprehensive study of the potential 
impacts of protection system single points of failure.
---------------------------------------------------------------------------

    \21\ Proposed Reliability Standard TPL-001-5 is not attached to 
this notice of proposed rulemaking (NOPR). The proposed Reliability 
Standard is available on the Commission's eLibrary document 
retrieval system in Docket No. RM19-10-000 and on the NERC website, 
www.nerc.com.
---------------------------------------------------------------------------

    12. NERC states that if the study of a protection system single 
point of failure for a single-line-to-ground fault (i.e., Category P5 
event) results in cascading, a corrective action plan is required.\22\ 
NERC considers this a relatively commonplace scenario, and it explains 
that an entity would be required to develop a corrective action plan if 
it determines that its system would be unable to meet the performance 
requirements of Table 1 for the Category P5 event.
---------------------------------------------------------------------------

    \22\ Proposed TPL-001-5 Reliability Standard, Table 1 (Steady 
State and Stability Performance Planning Events), Category P5 
requires the study of a single-line-to-ground faulted element (e.g., 
generator, transmission circuit or transformer) along with a failure 
to operate of a non-redundant component of the protection system 
(i.e., a single point of failure) protecting the faulted element.
---------------------------------------------------------------------------

    13. In contrast, NERC proposes revisions to Table 1 to include the 
study of a protection system single point of failure in combination 
with a three-phase fault as an extreme event, which does not require a 
corrective action plan. NERC avers in its petition that the three-phase 
fault scenario is much rarer (compared to the single-line-to-ground 
fault). According to NERC, like the other extreme events in the 
proposed Reliability Standard, this scenario, while rare, could result 
in more significant impacts to an entity's system.\23\ Under this 
approach, NERC asserts that, if an entity determines that its system 
will experience cascading as a result of a three-phase fault scenario, 
an evaluation of possible actions designed to reduce the likelihood or 
mitigate the consequences of the event will be conducted but a 
corrective action plan is not required.
---------------------------------------------------------------------------

    \23\ See Mandatory Reliability Standards for the Bulk-Power 
System, Order No. 693, 118 FERC ] 61,218, at P 1826, order on reh'g, 
Order No. 693-A, 120 FERC ] 61,053 (2007) (describing extreme events 
as ``events resulting in loss of two or more elements or Cascading'' 
that do not require a corrective action plan rather than assigning a 
quantitative probability to the event).
---------------------------------------------------------------------------

    14. Based on a historical analysis of NERC data on protection 
system misoperations, NERC asserts that the expected likelihood of a 
three-phase fault event occurring and resulting in the most severe 
impacts would be small. NERC states that it reviewed over 12,000 
protection system misoperations in its Misoperation Information Data 
Analysis System (MIDAS) database reported since 2011, of which only 28 
involved three-phase faults. Of those, NERC states that 10 involved 
breakers that failed to operate, and the remaining 18 involved breakers 
that were slow to operate.\24\ NERC explains that a failure to operate 
potentially indicates instances of a protection system single point of 
failure. While the potential for severe impacts from such events 
remains, NERC states that none of the 10 failure to trip scenarios 
reported since 2011 resulted in events that reached the threshold for 
reporting under Reliability Standard EOP-004 (Event Reporting).\25\ 
With regard to the Order No. 786 directives, NERC states that proposed 
Reliability Standard TPL-001-5 provides for a more complete 
consideration of factors for selecting which known outages will be 
included in near-term transmission planning horizon studies.
---------------------------------------------------------------------------

of at least 3,000 MW, or 200 MW or greater for all other entities, 
and total generation loss within one minute 2,000 MW or greater for 
entities in the Eastern or Western Interconnection, or 1,000 MW for 
entities in the ERCOT or Quebec Interconnection.
---------------------------------------------------------------------------

II. Discussion

    15. Pursuant to section 215(d)(2) of the FPA, the Commission 
proposes to approve proposed Reliability Standard TPL-001-5 as just, 
reasonable, not unduly discriminatory or preferential, and in the 
public interest. The proposed Reliability Standard will improve Bulk-
Power System reliability by requiring enhanced transmission system 
planning with regard to the study of protection system single points of 
failure in combination with a single-line-to-ground fault, as discussed 
in Order No. 754. The Commission also proposes to approve the 
associated violation risk factors, violation severity levels and 
implementation plan.
    16. With respect to the Order No. 786 directives, regarding planned 
maintenance outages and stability analysis for spare equipment 
strategy, the Commission proposes to determine that the revisions 
satisfy the directives. First, proposed Reliability Standard TPL-001-5 
provides for a more complete consideration of factors for selecting 
which known outages will be included in near-term transmission planning 
horizon studies. In particular, the modifications reflected in proposed 
Reliability Standard TPL-001-5 address the Commission's concern that 
the exclusion of known outages of less than six months in currently-
effective Reliability Standard TPL-001-4 could result in outages of 
significant facilities not being studied. Second, the proposed 
Reliability Standard modifies requirements for stability analysis to 
require an entity to assess the impact of the possible unavailability 
of long lead time equipment, consistent with the entity's spare 
equipment strategy.
    17. In addition, the Commission, pursuant to section 215(d)(5) of 
the FPA, proposes to direct that NERC develop modifications to the 
Reliability Standards because certain protection system single points 
of failure may not be fully addressed even with the implementation of 
proposed Reliability Standard TPL-001-5. As discussed below, the 
Commission is concerned that the proposed Reliability Standard does not 
require responsible entities to develop corrective action plans to 
address protection system single points

[[Page 30643]]

of failure in combination with a three-phase fault if planning studies 
indicate potential cascading. Accordingly, the Commission proposes to 
direct that NERC develop modifications to the Reliability Standards to 
require corrective action plans for protection system single points of 
failure in combination with three-phase faults if planning studies 
indicate potential cascading.

A. The Record Indicates There Is a Reliability Gap for a Protection 
System Single Point of Failure in Combination With a Three-Phase Fault

    18. While protection system single points of failure in combination 
with a three-phase fault must be studied under the proposed Reliability 
Standard to determine the impact of failure, the Commission believes 
that the record may not support NERC's contention that corrective 
action plans should not be required even when studies of the event 
indicate the potential for cascading. Specifically, NERC asserts that 
protection system single points of failure in combination with a three-
phase fault is an extreme event that does not require a corrective 
action plan, even in cases where the study results indicate potential 
cascading. NERC claims that protection system single points of failure 
in combination with a three-phase fault are rare and, ``[l]ike all of 
the `extreme events' scenarios in this [TPL-001 Standard risk-based] 
framework, the impacts of a protection system single point of failure 
in combination with a three phase fault could be severe in some cases, 
but are very unlikely.'' \26\ Based on the present record, it is 
unclear whether such contingencies are as rare as NERC maintains.

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

    19. A 2009 NERC Industry Advisory reported three system 
disturbances that occurred during a five-year period that were 
initiated by a protection system single point of failure in combination 
with a single-line-to-ground fault.\27\ According to the Industry 
Advisory and supporting documentation, all three events evolved into 
either a multi-phase fault or a three-phase fault with cascading.\28\ 
Moreover, in the 2012 Informational Filing, NERC reported that it is 
not uncommon for a single-line-to-ground fault to evolve into a multi-
phase fault, and NERC stated that studies solely on single-line-to-
ground faults may understate the reliability risk of single points of 
failure of protection systems.\29\ As mentioned below, the NERC 
standard drafting team pointed to the likelihood of a single-line-to-
ground fault evolving into a multi-phase fault when responding to 
stakeholder comments that a single-line-to-ground fault was a rare 
event.

Failure (March 30, 2009) (2009 NERC Industry Advisory).

failure of a single component (lockout or auxiliary relay) of a 
protection system.'').
    \29\ 2012 NERC Informational Filing at 3, 10 (``identif[ying] 
five events between 2004 and 2010 in which a single point of failure 
on a protection system caused, in whole or in part, an event on the 
Bulk-Power System . . .'').
---------------------------------------------------------------------------

    20. NERC indicates that it reviewed over 12,000 protection system 
misoperations and determined that only 28 involved three-phase faults 
from 2011 through 2018. However that averages to approximately one 
three-phase fault event every three months. NERC, moreover, indicates 
that ten of those 28 misoperations involved breakers that failed to 
operate that could reasonably be assumed to be representative of 
protection system single points of failure, which averages to about one 
event every 8 months.\30\ Although we recognize that three-phase faults 
constitute a relatively small subset of all protection system 
operations, under the following measure of one protection system single 
point of failure every 8 months, the occurrence of three-phase faults 
with misoperations could reasonably be viewed as regular occurrences. 
Thus, based on the information currently before us, we are not 
persuaded by NERC's analysis that three-phase faults are rare events 
that should be categorized with other extreme events in proposed 
Reliability Standard TPL-001-5 and should be studied but not have 
corrective action plans.
---------------------------------------------------------------------------

    \30\ NERC Petition at 26-27. NERC stated that none of the ten 
failure to trip scenarios reached the threshold for reporting under 
Reliability Standard EOP-004. Although NERC did not offer further 
explanation, system conditions such as off-peak load conditions 
could have contributed to whether Reliability Standard EOP-004 
thresholds were met.
---------------------------------------------------------------------------

    21. The record of development for proposed Reliability Standard 
TPL-001-5 also supports our concerns with the absence of a corrective 
action plan requirement. The development record evidences a standard 
drafting team repeatedly expressing concerns regarding the reliability 
risks of three-phase faults involving protection system single points 
of failure. Indeed, the standard drafting team evaluated and initially 
adopted more robust options to mitigate protection system single points 
of failure in combination with three-phase faults if studies indicated 
cascading, including requiring a corrective action plan or some 
variation of a corrective action plan.
    22. In the first draft of proposed Reliability Standard TPL-001-5, 
the standard drafting team included a draft requirement (Requirement 
R4.6) that would have addressed protection system single points of 
failure in combination with a three-phase fault, including a specific 
requirement for the development of a corrective action plan.\31\ After 
reviewing the unofficial comments on the proposal, the standard 
drafting team provided the following response:
---------------------------------------------------------------------------

    \31\ NERC Petition, Ex. G (Summary of Development and Complete 
Record of Development) at page 372-373 of pdf (``If the analysis 
concludes there is Cascading caused by the occurrence of Table 1 
extreme events listed in the stability column for events 2e-2h, a 
Corrective Action Plan shall be developed.'').

    The [standard drafting team (SDT)] recognized that the industry 
comments . . . were particularly negative. The SDT would like to 
address the most common comment received: Requiring Corrective 
Action Plans as part of Requirement R4.6 goes beyond the scope of 
the SAR, was not part of the recommendations from the SPCS/SAMS 
report titled ``Order No. 754 Assessment of Protection System Single 
Points of Failure Based on the Section 1600 Data Request'', and/or 
is not justifiable given the low likelihood of occurrence. . . . 
While it is clear that a [single point of failure (SPF)] for a 
Protection System component may lead to significantly longer Delayed 
Clearing and notably worse system response than typically analyzed 
breaker failure conditions, the industry has indicated that the 
probability of simultaneous SPF occurrence with a bolted three-phase 
fault is low. Therefore the SDT has restored the assessment of SPF 
for a Protection System component with a three-phase fault to 
language consistent with TPL-001-4 Requirement 4.5.\32\
---------------------------------------------------------------------------

    \32\ Id. at page 810 of pdf.

    While the standard drafting team agreed to remove the corrective 
action plan provision in response to the stakeholder comments, the 
following language from the standard drafting team's response stressed 
the reliability concerns posed by protection system single points of 
failure in combination with a three-phase fault, and suggested that the 
---------------------------------------------------------------------------
related risks are ``underappreciated'':

    The SPF for a Protection System component is an important topic 
that, the SDT believes, may involve risks that are underappreciated. 
The SDT considered using Corrective Action Plan changes in proposed 
Requirement 4.6 or a new Table 1 Planning Events Category P8 to 
emphasize the importance of this issue, but given the industry 
comments and lack of a FERC directive did not ``raise the bar'' at 
this time. The SDT would like to document an important 
considerations (sic) it considered, that the fault conditions and 
system performance requirement, referred to as Performance Measure, 
of the Order 754 data

[[Page 30644]]

request were very similar to those of Extreme Events of TPL-001-4 
Table 1, namely three-phase fault application and conditions that 
can indicate Cascading. The primary conclusive finding of the SPCS/
SAMS report was: ``analysis of the data demonstrates the existence 
of a reliability risk associated with single points of failure in 
protection systems that warrants further action.'' Further, the 
SPCS/SAMS report concluded that: ``additional emphasis in planning 
studies should be placed on assessment of three-phase faults 
involving protection system single points of failure.'' \33\
---------------------------------------------------------------------------

    \33\ Id.

    The standard drafting team's above response acknowledged the 
importance of a corrective action plan and noted conclusive findings of 
the SPCS/SAMS report that the reliability risk associated with 
protection system single points of failure warrants further action. The 
standard drafting team, nonetheless, indicated that ``lacking a FERC 
directive'' it would remove the corrective action plan provision.
    23. The standard drafting team then developed a second draft of 
proposed Reliability Standard TPL-001-5. The second draft did not 
require a corrective action plan by name. Rather, the standard drafting 
team developed and submitted for ballot a new provision requiring that, 
when system studies show that a protection system single points of 
failure in combination with a three-phase fault results in system 
cascading, the entity must take specific actions, namely ``listing 
system deficiencies, the associated actions needed to prevent the 
system from Cascading and the associated timetable for 
implementation.'' \34\ Further, the proposed provision would require 
follow-up in annual planning assessments for ``continued validity and 
implementation status.''
---------------------------------------------------------------------------

    \34\ Id. at page 824 of pdf (proposed Requirement 4.2.2).
---------------------------------------------------------------------------

    24. The standard drafting team developed a technical rationale 
document that accompanied the second draft of the proposed Reliability 
Standard.\35\ In the draft technical rationale document, the standard 
drafting team explained the technical basis for draft Requirement 
R4.2.2:
---------------------------------------------------------------------------

    \35\ Id. at page 942 of pdf.

    Given the risk to BES reliability, additional emphasis in 
planning studies should be placed on assessment of three-phase 
faults involving Protection System SPF. This concern (the study of 
Protection System SPF) is appropriately addressed as an extreme 
event in TPL-001-4, Requirement R4, Part 4.2. While less probable 
than single-phase-to-ground faults, three-phase faults typically 
initiate as single-phase-to-ground and often evolve into three-phase 
faults, leading to Delayed Fault Clearing scenarios more severe than 
the Table 1 P5 event. Therefore, TPL-001-4, Requirement R4, Part 
4.5, which specifies that an evaluation of possible mitigating 
actions be conducted if analysis concludes there is cascading caused 
by the occurrence of this extreme event, is inadequate to address 
the risk of Protection System component SPF to the reliability of 
the BES.\36\
---------------------------------------------------------------------------

    \36\ Id. at page 950-951 of pdf (emphasis added).

    Again, the standard drafting team expressed its concerns regarding 
the reliability risks associated with a protection system single point 
of failure in combination with a three-phase fault. The standard 
drafting team addressed the stakeholder comments regarding the 
perceived low risk of such conditions by pointing out that ``[w]hile 
less probable than single-phase-to-ground faults, three-phase faults 
typically initiate as single-phase-to-ground and often evolve into 
three-phase faults, leading to Delayed Fault Clearing scenarios more 
severe than the Table 1 P5 event.'' \37\ Further, the standard drafting 
team noted the inadequacy of simply conducting an ``evaluation'' as set 
forth in the relevant provision of the current Reliability 
Standard.\38\
---------------------------------------------------------------------------

    \37\ Id.
    \38\ The second draft of Reliability Standard TPL-001-5, was 
voted down by stakeholders, with stakeholders suggesting the removal 
of Requirement R4.2.2 again suggesting that three-phase fault 
followed by a protection failure is a low probability event. Id. at 
page 1327 of pdf.
---------------------------------------------------------------------------

    25. The standard drafting team developed a third draft of the 
proposed Reliability Standard. This third draft removed the more robust 
provision (proposed Requirement R4.2.2) in favor of the currently 
proposed language in Requirement 4.2, which requires that ``[i]f the 
analysis concludes there is Cascading caused by the occurrence of 
extreme events, an evaluation of possible actions designed to reduce 
the likelihood or mitigate the consequences of the event(s) shall be 
conducted.'' Significantly, however, in the draft technical rationale 
document associated with the second draft of the proposed Reliability 
Standard, the standard drafting team stated that merely requiring that 
``an evaluation of possible mitigating actions be conducted if analysis 
concludes there is cascading caused by the occurrence of this extreme 
event, is inadequate to address the risk of Protection System component 
SPF to the reliability of the BES.'' \39\
---------------------------------------------------------------------------

    \39\ Id. at page 951 of pdf (emphasis added).
---------------------------------------------------------------------------

    26. The standard development history discussed above therefore 
supports our concern that there is a potential reliability gap with 
respect to the proposed Reliability Standard's treatment of protection 
system single points of failure in combination with a three-phase 
fault.\40\
---------------------------------------------------------------------------

    \40\ The standard development record indicates several 
stakeholder comments in support of a corrective action plan 
requirement for protection system single points of failure in 
combination with a three-phase fault that was proposed in the third 
draft. For example, one commenter suggested ``the best way to 
achieve this [corrective action plan] requirement is through the 
creation of a P8 [new category planning event] contingency rather 
than extreme events.'' Another commenter stated it ``does not 
believe though that the language . . . goes far enough . . . and 
believes a corrective action plan should be required.'' Id. at pages 
2283, 2291, 2415, and 2424 of pdf.
---------------------------------------------------------------------------

B. Commission Proposal

    27. The Commission, pursuant to section 215(d)(5) of the FPA, 
proposes to direct that NERC develop modifications to require 
corrective action plans for protection system single points of failure 
in combination with three-phase faults if planning studies indicate 
potential cascading. While we do not propose to prescribe how NERC 
should respond to the proposed directive, we discuss below certain 
possible alternatives.
    28. NERC could address the proposed directive by modifying the 
current Category P5 proposal for single-line-to-ground faults (that 
already includes a P5 corrective action plan) to include language, such 
as, a footnote stating that the simulation of Delayed Fault Clearing 
must consider that a single-line-to-ground faulted condition may evolve 
to all three-phases before protection system action operates to clear 
the fault. Alternatively, NERC could modify the Reliability Standard to 
have a new Category planning event that would require a corrective 
action plan for the study of a protection system single point of 
failure in combination with a three-phase fault if the study indicates 
cascading.\41\
---------------------------------------------------------------------------

    \41\ See id. at page 1506 and 1746 of pdf.
---------------------------------------------------------------------------

    29. In addition, we recognize that during the standard drafting 
process for proposed Reliability Standard TPL-001-5 some stakeholders 
were concerned with incurring significant costs to mitigate protection 
system single points of failure in combination with a three-phase 
fault, while others stated that such actions do not usually incur 
significant costs.\42\ While we are aware of the potential for 
increased cost under this proposal, we understand that there are likely 
cost-effective actions that could be taken to mitigate a protection 
system single point of failure in combination with a three-phase fault.

[[Page 30645]]

For example, a corrective action plan to eliminate a single point of 
failure of protection system could add a redundant lockout relay in the 
control circuitry of a protection system, which would eliminate 
occurrence of those events reported in the 2009 NERC Industry 
Advisory.\43\ As another option, an entity could add control center 
monitoring and reporting functions to a DC battery bank or to a 
communication system of a communication-aided protection scheme so that 
system operators are aware of their failure.\44\ To better understand 
the potential for increased costs and other implementation issues, the 
Commission seeks comment on how many corrective action plans are 
expected for protection system single points of failure in combination 
with a three-phase fault if study results indicate cascading.
---------------------------------------------------------------------------

    \42\ See, e.g., id. at page 1016 (Seattle City Light), 1019 
(Arizona Public Service), 1044 (Northeast Power Coordinating 
Council), 1048 (Eversource Energy), 1331 and 1333 (Standard Drafting 
Team Response to Commenters) of pdf.
    \43\ NERC Petition at 20 (``most, if not all, constituent parts 
of the control circuitry are generally unmonitored, may fail, and 
may remain undetected until periodic testing is conducted. This is 
particularly significant for non-redundant auxiliary relays or 
lockout relays within the control circuitry because they may be used 
for multiple functions. . . .''). In addition, the standard drafting 
team stated that ``[i]t is emphasized that Footnote 13 does not 
prescribe any level of redundancy . . . . If, after proper 
consideration and simulation, required System performance is 
achieved, then there may be no impetus to make non-redundant 
components of a Protection System redundant. On the other hand, 
after proper consideration and simulation it is demonstrated that 
required System performance is not achieved, making non-redundant 
components of a Protection System redundant may be but one of many 
alternatives for corrective actions to obtain required System 
performance.'' Id., Ex. G at page 162 of pdf.
    \44\ NERC Petition at 18-19 (stating that ``[f]ootnote 13 
provides that certain non-redundant components that are both 
monitored and reported at a Control Center would not need to be 
considered as part of planning studies. This includes the 
communications systems identified in footnote 13.b. The standard 
drafting team considered that the monitoring and reporting of a non-
redundant component to a centralized location (i.e., the Control 
Center) would facilitate prompt identification and correction of 
abnormal conditions to minimize the exposure to and consequence of 
the failed component . . . Similar to footnote 13.b, monitoring and 
reporting the status of the DC supply to a centralized location 
[i.e., footnote 13.c] can be considered a sufficient alternative to 
physical redundancy if the result is prompt notification and 
remediation which minimizes the exposure to and consequence of DC 
supply failure'').
---------------------------------------------------------------------------

    30. To ensure no delay and to align the effective date of the 
proposed directive with the current implementation plan of proposed 
Reliability Standard TPL-001-5, the Commission proposes to direct that 
NERC address the directive within one year of the effective date of a 
final rule.\45\ The Commission seeks comments on its proposals.

III. Information Collection Statement

    31. The FERC-725N information collection requirements contained in 
this notice of proposed rulemaking are subject to review by the Office 
of Management and Budget (OMB) under section 3507(d) of the Paperwork 
Reduction Act of 1995.\46\ OMB's regulations require approval of 
certain information collection requirements imposed by agency 
rules.\47\ Upon approval of a collection of information, OMB will 
assign an OMB control number and expiration date. Respondents subject 
to the filing requirements of this rule will not be penalized for 
failing to respond to these collections of information unless the 
collections of information display a valid OMB control number. The 
Commission solicits comments on the Commission's need for this 
information, whether the information will have practical utility, the 
accuracy of the burden estimates, ways to enhance the quality, utility, 
and clarity of the information to be collected or retained, and any 
suggested methods for minimizing respondents' burden, including the use 
of automated information techniques.

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

    32. The Commission bases its paperwork burden estimates on the 
changes in paperwork burden presented by proposed Reliability Standard 
TPL-001-5. The NERC Compliance Registry, as of May 10, 2019, identifies 
approximately 144 planning coordinators and transmission planners in 
the United States that are subject to mandatory compliance with this 
proposed Regulatory Standard. Of the 144 entities 62 of the entities 
are registered as both transmission planners and planning coordinators. 
The register indicates there are seven entities registered as planning 
coordinators and 137 entities registered as transmission planners.
    33. Burden Estimate: \48\ The estimated burden and cost for the 
requirements contained in this proposed rule follows:
---------------------------------------------------------------------------

    \48\ ``Burden'' is the total time, effort, or financial 
resources expended by persons to generate, maintain, retain, or 
disclose or provide information to or for a Federal agency. For 
further explanation of what is included in the information 
collection burden, refer to 5 CFR 1320.3.
    \49\ We consider the filing of an application to be a 
``response.''
    \50\ Hourly costs are based on the Bureau of Labor Statistics 
(BLS) figures for May 2017 (Sector 22, Utilities) for wages (https://www.bls.gov/oes/current/naics2_22.htm) and benefits for December 
2019 (https://www.bls.gov/news.release/ecec.nr0.htm). We estimate 
that an Office and Administrative Support (Occupation code: 43-0000) 
would perform the functions associated with recordkeeping 
requirements, at an average hourly cost (for wages and benefits) of 
$41.34. The functions associated with reporting requirements, we 
estimate, would be performed by an Electrical Engineer (Occupation 
code: 17-2051) at an average hourly cost of $68.10 including wages 
and benefits. These occupational categories' wage figures are 
averaged and weighted equally as follows: ($41.34 hour + 68.10 hour) 
/ 2 = $54.72/hour. The resulting wage figure is rounded to $55.00/
hour for use in calculating wage figures in the NOPR in Docket No. 
RM19-10-000.
    \51\ Entity count based on May 10, 2019 NERC Registration: 7 
entities register as Planning Coordinators (PC), 137 entities 
register as Transmission Planners (TP), and 62 entities register as 
both PCs and TPs.

    This notice of proposed rulemaking will not significantly change 
existing burdens on an ongoing basis. The Commission estimates a one-
time burden increase for Year 1 only because Year 1 represents a one-
time task not repeated in subsequent years.
    The one-time burden for FERC-725N information collection can be 
averaged over three years:

    Necessity of the Information: This notice of proposed rulemaking 
proposes to approve the requested modifications to a Reliability 
Standard pertaining to transmission planning. As discussed above, the 
Commission proposes to approve proposed Reliability Standard TPL-001-5 
pursuant to section 215(d)(2) of the FPA because it improves upon the 
currently-effective Reliability Standard TPL-001-4.
    Internal Review: The Commission has reviewed proposed Reliability 
Standard TPL-001-5 and made a determination that its action is 
necessary to implement section 215 of the FPA. The Commission has 
assured itself, by means of its internal review, that there is 
specific, objective support for the burden estimates associated with 
the information requirements.

V. Regulatory Flexibility Act Analysis

    38. The Regulatory Flexibility Act of 1980 (RFA) \54\ generally 
requires a description and analysis of proposed rules that will have 
significant economic impact on a substantial number of small 
entities.\55\ The Small Business Administration's (SBA) Office of Size 
Standards develops the numerical definition of a small business.\56\ 
The SBA revised its size standard for electric utilities (effective 
January 22, 2014) to a standard based on the number of employees, 
including affiliates (from the prior standard based on megawatt hour 
sales).\57\

    39. Proposed Reliability Standard TPL-001-5 is expected to impose 
an additional burden on 206 entities \58\ (planning coordinators and 
transmission planners).
---------------------------------------------------------------------------

    \58\ Public utilities may fall under one of several different 
categories, each with a size threshold based on the company's number 
of employees, including affiliates, the parent company, and 
subsidiaries. For the analysis in this NOPR, we are using a 500 
employee threshold due to each affected entity falling within the 
role of Electric Bulk Power Transmission and Control (NAISC Code: 
221121).
---------------------------------------------------------------------------

    40. Of the 206 affected entities discussed above, we estimate that 
approximately 10 percent of the affected entities are small entities. 
We estimate that each of the 21 small entities to whom the proposed 
modifications to proposed Reliability Standard TPL-001-5 apply will 
incur one-time costs of approximately $1,980 per entity to implement 
the proposed Reliability Standard. We do not consider the estimated 
costs for these 21 small entities to be a significant economic impact. 
Accordingly, we propose to certify that proposed Reliability Standard 
TPL-001-5 will not have a significant economic impact on a substantial 
number of small entities.
