Standard IRO-001-4 Guidelines and Technical Basis

Guidelines and Technical Basis
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Rationale for Applicability:
Purchasing-Selling Entity and Load-Serving Entity have been deleted from the approved IRO001-1.1 as they are not listed as entities that the Reliability Coordinator directs in Functional
Model v5.
Rationale for Change from Reliability Directive to Operating Instruction:
The change from Reliability Directive to Operating Instruction throughout the standard is in
response to NOPR paragraph 64 (…”We believe that directives from a reliability coordinator or
transmission operator should be mandatory at all times, and not just during emergencies
(unless contrary to safety, equipment, regulatory or statutory requirements). For example,
mandatory compliance with directives in non-emergency situations is important when a decision
is made to alter or maintain the state of an element on the interconnected transmission
network…”) This change is also consistent with the proposed COM-002-4.
Rationale for Requirements R2 and R3:
The Transmission Service Provider has been removed from Requirements R2 and R3 as the
Transmission Service Provider is not listed in the Functional Model as a recipient of corrective
actions issued by the Reliability Coordinator. This allows for the retirement of IRO-004-2.

Standard IRO-002-4 — Guidelines and Technical Basis

Guidelines and Technical Basis
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Changes made to the proposed definitions were made in order to respond to issues raised in
NOPR paragraphs 55, 73, and 74 dealing with analysis of SOLs in all time horizons, questions on
Protection Systems and Special Protection Systems in NOPR paragraph 78, and
recommendations on phase angles from the SW Outage Report (recommendation 27). The
intent of such changes is to ensure that Real-time Assessments contain sufficient details to
result in an appropriate level of situational awareness. Some examples include: 1) analyzing
phase angles which may result in the implementation of an Operating Plan to adjust generation
or curtail transactions so that a Transmission facility may be returned to service, or 2)
evaluating the impact of a modified Contingency resulting from the status change of a Special
Protection Scheme from enabled/in-service to disabled/out-of-service.
Rationale for Requirements:
The data exchange elements of Requirements R1 and R2 from approved IRO-002-2 have been
added back into proposed IRO-002-4 in order to ensure that there is no reliability gap. The SDT
found no proposed requirements in the current project that covered the issue. Voice
communication is covered in proposed COM-001-2 but data communications needs to remain
in IRO-002-4 as it is not covered in proposed COM-001-2. Staffing of communications and
facilities in corresponding requirements from IRO-002-2 is addressed in approved PER-004-2,
Requirement R1 and has been deleted from this draft.
Rationale for R2:
Requirement R2 from IRO-002-3 has been deleted because approved EOP-008-1, Requirement
R1, part 1.6.2 addresses redundancy and back-up concerns for outages of analysis tools. New
Requirement R4 has been added to address NOPR paragraphs 96 and 97: “…As we explain
above, the reliability coordinator’s obligation to monitor SOLs is important to reliability because
a SOL can evolve into an IROL during deteriorating system conditions, and for potential system
conditions such as this, the reliability coordinator’s monitoring of SOLs provides a necessary
backup function to the transmission operator….”
Rationale for R4:
Requirement R4 added back from approved IRO-002-2 as the SDT found no proposed
requirements that covered the issues.

F. Associated Documents
Operating Plan - An Operating Plan includes general Operating Processes and specific
Operating Procedures. It may be an overview document which provides a prescription for
an Operating Plan for the next-day, or it may be a specific plan to address a specific SOL or
IROL exceedance identified in the Operational Planning Analysis (OPA). Consistent with the
NERC definition, Operating Plans can be general in nature, or they can be specific plans to
address specific reliability issues. The use of the term Operating Plan in the revised
TOP/IRO standards allows room for both. An Operating Plan references processes and
procedures, including electronic data exchange, which are available to the System Operator
on a daily basis to allow the operator to reliably address conditions which may arise
throughout the day. It is valid for tomorrow, the day after, and the day after that. Operating
Plans should be augmented by temporary operating guides which outline
prevention/mitigation plans for specific situations which are identified day-to-day in an OPA
or a Real-time Assessment (RTA). As the definition in the Glossary of Terms states, a
restoration plan is an example of an Operating Plan. It contains all the overarching
principles that the System Operator needs to work his/her way through the restoration
process. It is not a specific document written for a specific blackout scenario but rather a
collection of tools consisting of processes, procedures, and automated software systems
that are available to the operator to use in restoring the system. An Operating Plan can in
turn be looked upon in a similar manner. It does not contain a prescription for the specific
set-up for tomorrow but contains a treatment of all the processes, procedures, and
automated software systems that are at the operator’s disposal. The existence of an
Operating Plan, however, does not preclude the need for creating specific action plans for
specific SOL or IROL exceedances identified in the OPA. When a Reliability Coordinator
performs an OPA, the analysis may reveal instances of possible SOL or IROL exceedances for
pre- or post-Contingency conditions. In these instances, Reliability Coordinators are
expected to ensure that there are plans in place to prevent or mitigate those SOLs or IROLs,
should those operating conditions be encountered the next day. The Operating Plan may
contain a description of the process by which specific prevention or mitigation plans for
day-to-day SOL or IROL exceedances identified in the OPA are handled and communicated.
This approach could alleviate any potential administrative burden associated with perceived
requirements for continual day-to-day updating of “the Operating Plan document” for
compliance purposes.

Guidelines and Technical Basis
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Changes made to the proposed definitions were made in order to respond to issues raised in
NOPR paragraphs 55, 73, and 74 dealing with analysis of SOLs in all time horizons, questions on
Protection Systems and Special Protection Systems in NOPR paragraph 78, and
recommendations on phase angles from the SW Outage Report (recommendation 27). The
intent of such changes is to ensure that Real-time Assessments contain sufficient details to
result in an appropriate level of situational awareness. Some examples include: 1) analyzing
phase angles which may result in the implementation of an Operating Plan to adjust generation
or curtail transactions so that a Transmission facility may be returned to service, or 2)
evaluating the impact of a modified Contingency resulting from the status change of a Special
Protection Scheme from enabled/in-service to disabled/out-of-service.
Rationale for R1:
Revised in response to NOPR paragraph 96 on the obligation of Reliability Coordinators to
monitor SOLs. Measure M1 revised for consistency with TOP-003-3, Measure M1.
Rationale for R2 and R3:
Requirements added in response to IERP and SW Outage Report recommendations concerning
the coordination and review of plans.
Rationale for R5 and R6:
In Requirements R5 and R6 the use of the term ‘impacted’ and the tie to the Operating Plan
where notification protocols will be set out should minimize the volume of notifications.

Guidelines and Technical Basis
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT adoption, the text from the rationale
text boxes was moved to this section.
Rationale for Definitions:
Changes made to the proposed definitions were made in order to respond to issues raised in
NOPR paragraphs 55, 73, and 74 dealing with analysis of SOLs in all time horizons, questions on
Protection Systems and Special Protection Systems in NOPR paragraph 78, and
recommendations on phase angles from the SW Outage Report (recommendation 27). The
intent of such changes is to ensure that Real-time Assessments contain sufficient details to result
in an appropriate level of situational awareness. Some examples include: 1) analyzing phase
angles which may result in the implementation of an Operating Plan to adjust generation or
curtail transactions so that a Transmission facility may be returned to service, or 2) evaluating
the impact of a modified Contingency resulting from the status change of a Special Protection
Scheme from enabled/in-service to disabled/out-of-service.
Rationale for Applicability Changes:
Changes were made to applicability based on IRO FYRT recommendation to address the need for
UVLS and UFLS information in the data specification.
The Interchange Authority was removed because activities in the Coordinate Interchange
standards are performed by software systems and not a responsible entity. The software, not a
functional entity, performs the task of accepting and disseminating interchange data between
entities. The Balancing Authority is the responsible functional entity for these tasks.
The Planning Coordinator and Transmission Planner were removed from Draft 2 as those entities
would not be involved in a data specification concept as outlined in this standard.
Rationale:
Proposed Requirement R1, Part 1.1:
Is in response to issues raised in NOPR paragraph 67 on the need for obtaining non-BES and
external network data necessary for the Reliability Coordinator to fulfill its responsibilities.
Proposed Requirement R1, Part 1.2:
Is in response to NOPR paragraph 78 on relay data.
Proposed Requirement R3, Part 3.3:

Page 8 of 9

Standard IRO-010-2 — Guidelines and Technical Basis

Is in response to NOPR paragraph 92 where concerns were raised about data exchange through
secured networks.
Corresponding changes have been made to proposed TOP-003-3.

F. Associated Documents
Operating Plan - An Operating Plan includes general Operating Processes and specific
Operating Procedures. It may be an overview document which provides a prescription for
an Operating Plan for the next-day, or it may be a specific plan to address a specific SOL or
IROL exceedance identified in the Operational Planning Analysis (OPA). Consistent with the
NERC definition, Operating Plans can be general in nature, or they can be specific plans to
address specific reliability issues. The use of the term Operating Plan in the revised
TOP/IRO standards allows room for both. An Operating Plan references processes and
procedures, including electronic data exchange, which are available to the System Operator
on a daily basis to allow the operator to reliably address conditions which may arise
throughout the day. It is valid for tomorrow, the day after, and the day after that. Operating
Plans should be augmented by temporary operating guides which outline
prevention/mitigation plans for specific situations which are identified day-to-day in an OPA
or a Real-time Assessment (RTA). As the definition in the Glossary of Terms states, a
restoration plan is an example of an Operating Plan. It contains all the overarching
principles that the System Operator needs to work his/her way through the restoration
process. It is not a specific document written for a specific blackout scenario but rather a
collection of tools consisting of processes, procedures, and automated software systems
that are available to the operator to use in restoring the system. An Operating Plan can in
turn be looked upon in a similar manner. It does not contain a prescription for the specific
set-up for tomorrow but contains a treatment of all the processes, procedures, and
automated software systems that are at the operator’s disposal. The existence of an
Operating Plan, however, does not preclude the need for creating specific action plans for
specific SOL or IROL exceedances identified in the OPA. When a Reliability Coordinator
performs an OPA, the analysis may reveal instances of possible SOL or IROL exceedances for
pre- or post-Contingency conditions. In these instances, Reliability Coordinators are
expected to ensure that there are plans in place to prevent or mitigate those SOLs or IROLs,
should those operating conditions be encountered the next day. The Operating Plan may
contain a description of the process by which specific prevention or mitigation plans for
day-to-day SOL or IROL exceedances identified in the OPA are handled and communicated.
This approach could alleviate any potential administrative burden associated with perceived
requirements for continual day-to-day updating of “the Operating Plan document” for
compliance purposes.

Guidelines and Technical Basis
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
This standard is in response to issues raised in NOPR paragraph 90 and recommendations made
by the Independent Expert Review Panel and SW Outage Report on the need for an outage
coordination standard. It allows for one cohesive standard to address all outage coordination
concerns as opposed to having multiple requirements spread throughout the various standards.
Rationale for Time Horizon:
The official definition of the Operations Planning Time Horizon is: “operating and resource plans
from day‐ahead up to and including seasonal.” The SDT equates ‘seasonal’ as being up to one
year out and that these requirements covers the period from day-ahead to one year out.
Rationale for R3:
Planning Assessment is a defined term and a document that Planning Coordinators and
Transmission Planners already have to produce for approved TPL-001-4. It is not a compilation
of load flow studies but a textual summary of what was found in those studies including
rationales and assumptions.
Rationale for R4:
The SDT has re-written Requirement R4 to show that the process starts with the Planning
Assessments created by the Planning Coordinator and Transmission Planner and then those
Planning Assessments are reviewed and reconciled as needed with the Reliability Coordinator.
This is in response to comments in paragraph 90 of the FERC NOPR about directly involving the
Reliability Coordinator in the planning process for periods beyond the present one year
outreach as well as recommendations in the IERP. The re-write should not be construed as
relieving the Reliability Coordinator of responsibilities in this area but simply as a reflection of
how the process actually starts.
In the future, the SDT believes that such coordination should take place in the TPL standards
and to support that position, the SDT has created an item in a draft SAR for TPL-001-4 that
would revise Requirement R8 to make the Reliability Coordinator an explicit party in the review
process described there.
In addition, the SDT will submit a request to the Functional Model Working Team to adjust the
roles and responsibilities of the Reliability Coordinator to this new paradigm.

Compliance Monitoring Process
1.1. Compliance Enforcement Authority
As defined in the NERC Rules of Procedure, “Compliance Enforcement Authority”
(CEA) means NERC or the Regional Entity in their respective roles of monitoring
and enforcing compliance with the NERC Reliability Standards.
1.2. Compliance Monitoring and Assessment Processes
As defined in the NERC Rules of Procedure, “Compliance Monitoring and
Assessment Processes” refers to the identification of the processes that will be
used to evaluate data or information for the purpose of assessing performance
or outcomes with the associated reliability standard.
1.3. Data Retention
The following evidence retention periods identify the period of time an entity is
required to retain specific evidence to demonstrate compliance. For instances
where the evidence retention period specified below is shorter than the time
since the last audit, the Compliance Enforcement Authority may ask an entity to
provide other evidence to show that it was compliant for the full time period
since the last audit.
Each Balancing Authority, Transmission Operator, Generator Operator, and
Distribution Provider shall each keep data or evidence for each applicable
Requirement R1 through R11, and R15 through R20 and Measure M1 through
M11, and M15 through M20 for the current calendar year and one previous
calendar year, with the exception of operator logs and voice recordings which
shall be retained for a minimum of ninety calendar days, unless directed by its
Compliance Enforcement Authority to retain specific evidence for a longer
period of time as part of an investigation.
Each Transmission Operator shall retain evidence for three calendar years of any
occasion in which it has exceeded an identified IROL and its associated IROL Tv as
specified in Requirement R12 and Measure M12 and that it initiated its
Operating Plan to mitigate a SOL exceedance as specified in Requirement R14
and Measurement M14.
Each Transmission Operator shall keep data or evidence for Requirement R13
and Measure M13 for a rolling 30-day period, unless directed by its Compliance
Enforcement Authority to retain specific evidence for a longer period of time as
part of an investigation.

Page 7 of 19

Standard TOP-001-3 — Transmission Operations

If a Balancing Authority, Transmission Operator, Generator Operator, or
Distribution Provider is found non-compliant, it shall keep information related to
the non-compliance until mitigation is complete and approved or the time
period specified above, whichever is longer.
The Compliance Enforcement Authority shall keep the last audit records and all
requested and submitted subsequent audit records.

D. Regional Variances

None.
F. Associated Documents
The SDT has created the SOL Exceedance White Paper as guidance on SOL issues and the
URL for that document is: http://www.nerc.com/pa/stand/Pages/TOP0013RI.aspx.
Operating Plan - An Operating Plan includes general Operating Processes and specific
Operating Procedures. It may be an overview document which provides a prescription for
an Operating Plan for the next-day, or it may be a specific plan to address a specific SOL or
IROL exceedance identified in the Operational Planning Analysis (OPA). Consistent with the
NERC definition, Operating Plans can be general in nature, or they can be specific plans to
address specific reliability issues. The use of the term Operating Plan in the revised
TOP/IRO standards allows room for both. An Operating Plan references processes and
procedures, including electronic data exchange, which are available to the System Operator
on a daily basis to allow the operator to reliably address conditions which may arise
throughout the day. It is valid for tomorrow, the day after, and the day after that. Operating
Plans should be augmented by temporary operating guides which outline
prevention/mitigation plans for specific situations which are identified day-to-day in an OPA
or a Real-time Assessment (RTA). As the definition in the Glossary of Terms states, a
restoration plan is an example of an Operating Plan. It contains all the overarching
principles that the System Operator needs to work his/her way through the restoration
process. It is not a specific document written for a specific blackout scenario but rather a
collection of tools consisting of processes, procedures, and automated software systems
that are available to the operator to use in restoring the system. An Operating Plan can in
turn be looked upon in a similar manner. It does not contain a prescription for the specific
set-up for tomorrow but contains a treatment of all the processes, procedures, and
automated software systems that are at the operator’s disposal. The existence of an
Operating Plan, however, does not preclude the need for creating specific action plans for
specific SOL or IROL exceedances identified in the OPA. When a Reliability Coordinator
performs an OPA, the analysis may reveal instances of possible SOL or IROL exceedances for
pre- or post-Contingency conditions. In these instances, Reliability Coordinators are
expected to ensure that there are plans in place to prevent or mitigate those SOLs or IROLs,
should those operating conditions be encountered the next day. The Operating Plan may
contain a description of the process by which specific prevention or mitigation plans for
day-to-day SOL or IROL exceedances identified in the OPA are handled and communicated.
This approach could alleviate any potential administrative burden associated with perceived
requirements for continual day-to-day updating of “the Operating Plan document” for

Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Rationale for Requirement R3:
The phrase ‘cannot be physically implemented’ means that a Transmission Operator may
request something to be done that is not physically possible due to its lack of knowledge of the
system involved.
Rationale for Requirement R10:
New proposed Requirement R10 is derived from approved IRO-003-2, Requirement R1, adapted
to the Transmission Operator Area. This new requirement is in response to NOPR paragraph 60
concerning monitoring capabilities for the Transmission Operator. New Requirement R11

Page 18 of 19

Standard TOP-001-3 — Transmission Operations
covers the Balancing Authorities. Monitoring of external systems can be accomplished via data
links.
Rationale for Requirement R13:
The new Requirement R13 is in response to NOPR paragraphs 55 and 60 concerning Real-time
analysis responsibilities for Transmission Operators and is copied from approved IRO-008-1,
Requirement R2. The Transmission Operator’s Operating Plan will describe how to perform the
Real-time Assessment. The Operating Plan should contain instructions as to how to perform
Operational Planning Analysis and Real-time Assessment with detailed instructions and timing
requirements as to how to adapt to conditions where processes, procedures, and automated
software systems are not available (if used). This could include instructions such as an
indication that no actions may be required if system conditions have not changed significantly
and that previous Contingency analysis or Real-time Assessments may be used in such a
situation.
Rationale for Requirement R14:
The original Requirement R8 was deleted and original Requirements R9 and R11 were revised in
order to respond to NOPR paragraph 42 which raised the issue of handling all SOLs and not just
a sub-set of SOLs. The SDT has developed a white paper on SOL exceedances that explains its
intent on what needs to be contained in such an Operating Plan. These Operating Plans are
developed and documented in advance of Real-time and may be developed from Operational
Planning Assessments required per proposed TOP-002-4 or other assessments. Operating Plans
could be augmented by temporary operating guides which outline prevention/mitigation plans
for specific situations which are identified day-to-day in an Operational Planning Assessment or
a Real-time Assessment. The intent is to have a plan and philosophy that can be followed by an
operator.
Rationale for Requirements R16 and R17:
In response to IERP Report recommendation 3 on authority.
Rationale for Requirement R18:
Moved from approved IRO-005-3.1a, Requirement R10. Transmission Service Provider,
Distribution Provider, Load-Serving Entity, Generator Operator, and Purchasing-Selling Entity
are deleted as those entities will receive instructions on limits from the responsible entities
cited in the requirement. Note – Derived limits replaced by SOLs for clarity and specificity. SOLs
include voltage, Stability, and thermal limits and are thus the most limiting factor.
Rationale for Requirements R19 and R20:
Added for consistency with proposed IRO-002-4, Requirement R1. Data exchange capabilities
are required to support the data specification concept in proposed TOP-003-3.

D. Regional Variances

E. Interpretations
None.
F. Associated Documents
Operating Plan - An Operating Plan includes general Operating Processes and specific
Operating Procedures. It may be an overview document which provides a prescription for
an Operating Plan for the next-day, or it may be a specific plan to address a specific SOL or
IROL exceedance identified in the Operational Planning Analysis (OPA). Consistent with the
NERC definition, Operating Plans can be general in nature, or they can be specific plans to
address specific reliability issues. The use of the term Operating Plan in the revised
TOP/IRO standards allows room for both. An Operating Plan references processes and
procedures which are available to the System Operator on a daily basis to allow the
operator to reliably address conditions which may arise throughout the day. It is valid for
tomorrow, the day after, and the day after that. Operating Plans should be augmented by
temporary operating guides which outline prevention/mitigation plans for specific
situations which are identified day-to-day in an OPA or a Real-time Assessment (RTA). As
the definition in the Glossary of Terms states, a restoration plan is an example of an
Operating Plan. It contains all the overarching principles that the System Operator needs to
work his/her way through the restoration process. It is not a specific document written for a
specific blackout scenario but rather a collection of tools consisting of processes,
procedures, and automated software systems that are available to the operator to use in
restoring the system. An Operating Plan can in turn be looked upon in a similar manner. It
does not contain a prescription for the specific set-up for tomorrow but contains a
treatment of all the processes, procedures, and automated software systems that are at the
operator’s disposal. The existence of an Operating Plan, however, does not preclude the
need for creating specific action plans for specific SOL or IROL exceedances identified in the
OPA. When a Reliability Coordinator performs an OPA, the analysis may reveal instances of
possible SOL or IROL exceedances for pre- or post-Contingency conditions. In these
instances, Reliability Coordinators are expected to ensure that there are plans in place to
prevent or mitigate those SOLs or IROLs, should those operating conditions be encountered
the next day. The Operating Plan may contain a description of the process by which specific
prevention or mitigation plans for day-to-day SOL or IROL exceedances identified in the OPA
are handled and communicated. This approach could alleviate any potential administrative
burden associated with perceived requirements for continual day-to-day updating of “the
Operating Plan document” for compliance purposes.

Guidelines and Technical Basis
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Rationale for Definitions:
Changes made to the proposed definitions were made in order to respond to issues raised in
NOPR paragraphs 55, 73, and 74 dealing with analysis of SOLs in all time horizons, questions on
Protection Systems and Special Protection Systems in NOPR paragraph 78, and
recommendations on phase angles from the SW Outage Report (recommendation 27). The
intent of such changes is to ensure that Real-time Assessments contain sufficient details to
result in an appropriate level of situational awareness. Some examples include: 1) analyzing
phase angles which may result in the implementation of an Operating Plan to adjust generation
or curtail transactions so that a Transmission facility may be returned to service, or 2)
evaluating the impact of a modified Contingency resulting from the status change of a Special
Protection Scheme from enabled/in-service to disabled/out-of-service.
Rationale for R1:
Terms deleted in Requirement R1 as they are now contained in the revised definition of
Operational Planning Analysis
Rationale for R2:
The change to Requirement R2 is in response to NOPR paragraph 42 and in concert with
proposed changes made to proposed TOP-001-4
Rationale for R3:
Changes in response to IERP recommendation
Rationale for R4 and R5:
These Requirements were added to address IERP recommendations
Rationale for R6 and R7:
Added in response to SW Outage Report recommendation 1

OR,
The Balancing
Authority did not
have a documented
specification for the
data necessary for it
to perform its analysis
functions and Realtime monitoring.

For the Requirement R3 and R4 VSLs only, the intent of the SDT is to start with the Severe VSL first and then to work your way to
the left until you find the situation that fits. In this manner, the VSL will not be discriminatory by size of entity. If a small entity
has just one affected reliability entity to inform, the intent is that that situation would be a Severe violation.

Guidelines and Technical Basis
Rationale:
During development of this standard, text boxes were embedded within the standard to explain
the rationale for various parts of the standard. Upon BOT approval, the text from the rationale
text boxes was moved to this section.
Rationale for Definitions:
Changes made to the proposed definitions were made in order to respond to issues raised in
NOPR paragraphs 55, 73, and 74 dealing with analysis of SOLs in all time horizons, questions on
Protection Systems and Special Protection Systems in NOPR paragraph 78, and
recommendations on phase angles from the SW Outage Report (recommendation 27). The
intent of such changes is to ensure that Real-time Assessments contain sufficient details to
result in an appropriate level of situational awareness. Some examples include: 1) analyzing
phase angles which may result in the implementation of an Operating Plan to adjust generation
or curtail transactions so that a Transmission facility may be returned to service, or 2)
evaluating the impact of a modified Contingency resulting from the status change of a Special
Protection Scheme from enabled/in-service to disabled/out-of-service.
Rationale for R1:
Changes to proposed Requirement R1, Part 1.1 are in response to issues raised in NOPR
paragraph 67 on the need for obtaining non-BES and external network data necessary for the
Transmission Operator to fulfill its responsibilities.
Proposed Requirement R1, Part 1.2 is in response to NOPR paragraph 78 on relay data. The
language has been moved from approved PRC-001-1.
Corresponding changes have been made to Requirement R2 for the Balancing Authority and to
proposed IRO-010-2, Requirement R1 for the Reliability Coordinator.
Rationale for R5:
Proposed Requirement R5, Part 5.3 is in response to NOPR paragraph 92 where concerns were
raised about data exchange through secured networks.

Project 2014-03 Revisions to TOP/IRO Reliability Standards
As part of the work in Project 2014-03 Revisions to TOP/IRO Reliability Standards, the SDT is proposing
changes to two existing definitions: Operational Planning Analysis and Real-time Assessment.
The currently-effective definition of Operational Planning Analysis is: “An analysis of the expected system
conditions for the next day’s operation. (That analysis may be performed either a day ahead or as much
as 12 months ahead.) Expected system conditions include things such as load forecast(s), generation
output levels, and known system constraints (transmission facility outages, generator outages, equipment
limitations, etc.).”
The proposed version of the definition of Operational Planning Analysis is: “An evaluation of projected
system conditions to assess anticipated (pre-Contingency) and potential (post-Contingency) conditions for
next-day operations. The evaluation shall reflect applicable inputs including, but not limited to, load
forecasts; generation output levels; Interchange; known Protection System and Special Protection System
status or degradation; Transmission outages; generator outages; Facility Ratings; and identified phase
angle and equipment limitations. (Operational Planning Analysis may be provided through internal
systems or through third-party services.)”
The currently-effective definition of Real-time Assessment is: “An examination of existing and expected
system conditions, conducted by collecting and reviewing immediately available data.”
The proposed version of the definition of Real-time Assessment is: “An evaluation of system conditions
using Real-time data to assess existing (pre-Contingency) and potential (post-Contingency) operating
conditions. The assessment shall reflect applicable inputs including, but not limited to: load, generation
output levels, known Protection System and Special Protection System status or degradation,
Transmission outages, generator outages, Interchange, Facility Ratings, and identified phase angle and
equipment limitations. (Real-time Assessment may be provided through internal systems or through thirdparty services.)”
The definitions were revised in response to issues raised in NOPR paragraphs 55, 73, and 74 on analysis
and monitoring of SOLs in all time horizons, NOPR paragraph 70 (updating study results in Real-time), and
NOPR paragraph 78 (Protection System coordination). The phase angle item was added in response to
SW Outage Report recommendation 27.
The two definitions are also employed in the following proposed project standards: TOP-001-3, TOP-0024, TOP-003-3, IRO-002-4, IRO-008-2, and IRO-010-2. These definitions are not used in any other
standards, either currently-effective or in development in any other project.
