​​Co​mment from APS:
 
Line 7 - The effective date may be tight since the winter study plans will need to be posted soon, but submit to subregional study groups to request a time extension if they percieve is necessary.
Line - 72 suggestion to add "under the IRO-017 outage coordination process" after the end of the sentence.
Line 83 - capitalize the entire term " Always Credible Multiple Contingencies"
Line 203 - suggestion to add "and the timeline in Appendix VI" after the end of the sentence.
Line 210 - suggestion to bold and underline "Case development is needed even if there are no studies performed for that season" to bring attention to this requirement.
Line 497 - suggestion to replace "transient voltage dip criteria" with "transient system performance"
General suggestion: Roles sections (K-N) should be moved before Section F (process) to define who is doing what prior to talking about the process itself.
 
Thanks for the opportunity to comment on this seasonal process document.

Reliability Coordinator Seasonal Operations
Planning Coordination Process, Rev. 2.0
Bonneville Power Administration Comments
March 16, 2018
Introduction
The Bonneville Power Administration (BPA) thanks Peak Reliability (Peak) for the opportunity to comment on the referenced document. A BPA representative participated on the small team contributing to the development of the Reliability Coordinator Seasonal Operations Planning Coordination Process (Seasonal Coordination Process) and improvements to the existing seasonal operations planning coordination process. Through that process Peak created an environment that provided the opportunity for the exchange of thoughtful comments and encouraged collaboration for addressing reliability of the interconnect system within and among the regional subgroups. BPA believes that joint development of the Seasonal Coordination process is beneficial for both transmission operators (TOPs) and Peak. BPA’s comments on the document follow:
General
BPA understands that the proposed Seasonal Coordination Process is voluntary or advisory and not mandated by Peak or any applicable reliability standards. The majority of BPA’s comments therefore propose edits to clarify the voluntary nature of the Seasonal Coordination Process, and replacing directive terms with advisory terminology. Other comments suggest edits to refer to Peak’s SOL Methodology to avoid duplication of those requirements when written out, including the risk of stating them differently and introducing the potential for different interpretations of the RC’s SOL Methodology requirements. Explanations are provided for all other comments.
Specific Comments
Line 7, add a date to clarify the effective date as follows: “effective May 1, 2018, beginning with for the seasonal studies for the winter of 2018/2019.”
Lines 11 - 12, replace “current version of the” with version number and add “or its successor” as follows: “current version of the Peak Reliability SOL Methodology for the Operations Horizon, rev. 8.1 (SOL Methodology) or its successor.”
Line 17, replace directive language and add review period as follows: “this document will be available for reviewed by TOP stakeholders at least 60 days prior to implementation.”
Lines 19 – 21, clarify RC does not govern and the voluntary nature of the Seasonal Coordination Process as follows: “The RC Seasonal Operations Planning Coordination Process is voluntary. Subregional study groups are encouraged, but not required, to follow the process set forth herein. The RC does not govern the subregional study groups. Although, the NERC Reliability Standards do not require reliability entities to perform seasonal operations planning, they do require the following:”
Line 32, clarify to add clear statement to address when the Seasonal Coordination Process is used: “The RC Seasonal Operations Planning Coordination Process is intended to fits”
Line 34 - 35, add “Real Time to 1-year” continuum to Operations Horizon in Fig. 1.
Line 38 - 42, revised to replace intentions with clear statements: “The studies performed as part of the RC Seasonal Operations Planning Coordination Process are neither not intended to be an extension of the TPL Planning Assessments, nor are they intended to serve the same purpose as the studies performed as part of the IRO-017 Outage Coordination Process.”
2
Line 47 - 53, revised to reflect that the RC does not govern the Seasonal Coordination Process, the Seasonal Coordination Process advisory status and subregional study group discretion: “The studies performed as part of The RC Seasonal Operations Planning Coordination Process encourages subregional study groups undertake studies that are intended to add real, tangible value to operations reliability, and .This process is intended to avoid performing routine studies each season that provide essentially the same results season after season. However, That said if a the subregional study groups retain discretion to sees value in performing certain studies on a routine basis, the subregional study group may do so. The RC Seasonal Operations Planning Coordination Process is intended to be flexible to address the needs of the RC and the TOPs within the RC subregional study group Area.”
Lines 56 - 61, confusing, revised to simply state that studies are subject to the SOL methodology: “The Seasonal studies performed as part of the RC Seasonal Operations Planning Coordination Process fall within the operations horizon (real-time through one year out), and therefore fall under the jurisdiction of the RC’s SOL Methodology. Accordingly, the concepts, principles, methods, technical criteria and requirements spelled out in are subject to the RC’s SOL Methodology, as described in relevant sections of this apply to the studies performed as part of the RC Seasonal Operations Planning Coordination Process.
Line 64 - 65, clarify voluntary nature of the Seasonal Coordination Process as follows: “The RC Seasonal Operations Planning Coordination Process is voluntary. Subregional study groups may determine the scope of seasonal studies the RC Seasonal Operations Planning Coordination Process to includes the following:”
Line 69, completing thought: “3. Coordinating/reviewing study results within and among the subregional study groups”
Line 73 - 74, clarify advisory status of the Seasonal Coordination Process: “The types of studies that are may be within scope of the RC Seasonal Operations Planning Coordination Process include the following:”
Line 82- 84, simplify and clarify applicable study requirements: “3. Studies to identify instability risks and stressing the system for Cascading or uncontrolled separation risks for single and multiple Contingencies and identifying potential IROLs, Always Credible multiple Contingencies, or N-1-1 or N-1-2 Contingency scenarios per consistent with the RC SOL Methodology.”
Line 84 – 88, duplicative of SOL Methodology requirements: These studies include stressing the system to reasonable maximum stressed conditions per the RC’s SOL Methodology and are aimed at identifying potential IROLs and non-IROL stability limits. Accordingly, the RC’s SOL Methodology has a major role in these studies.
Line 89, clarify advisory role of the Seasonal Coordination Process: “Analyses that are out of scope are may include those that are aimed at identifying thermal and . . .”
Line 97 - 99, clarify RC does not govern and advisory role of the Seasonal Coordination Process: “1. Providing a mechanism by which the RC and TOPs ensure that non-IROL may establish stability SOLs are established and may identify potential IROLs are identified consistent with the RC’s SOL Methodology.”
Line 102 - 105, clarify advisory role of the Seasonal Coordination Process: “3. Ensuring that Coordinating Operating Plans are in place prior to the beginning of each operating season, and to provide sufficient lead time to develop and coordinate relevant operating tools are developed and provide adequate training for System Operators and other operating personnel has been provided.”
Line 109 – 112, clarify responsibility for identifying IROLs and advisory role of the Seasonal Coordination Process: “5. Ensuring Encouraging consistent study methodologies and criteria when performing seasonal assessments, identifying instability risks, identifying potential IROLs and verifying acceptable performance for the projected seasonal system conditions.”
3
Line 127 – 129, clarify advisory role of the Seasonal Coordination Process: “Once these six steps are completed, the Seasonal Operations Planning Coordination Process is deemed completed. There may be a need to pursue necessary follow up Actions outside the seasonal process may follow,.”
Line 133 – 142, simplify and reinforce advisory role of the Seasonal Coordination Process: “Determining which studies to perform for any given season is a critical aspect to the RC Seasonal Operations Planning Coordination Process. The RC Seasonal Operations Planning Coordination Process affords ample flexibility in the studies that are performed for a given season. As we stated earlier in this document, Subregional study groups are encouraged to perform seasonal the studies performed as part of the RC Seasonal Operations Planning Coordination Process are intended to that add real, tangible value to operations reliability. It is intended that this process avoid performing routine studies each season that provide essentially the same results season after season. That said, However, if a subregional study group sees value in performing certain studies on a routine basis, the subregional study group may do so. Therefore, determining which studies to perform for any given season is a critical aspect to the RC Seasonal Operations Planning Coordination Process.”
Line 143 – 146, clarify RC does not govern and the advisory role of the Seasonal Coordination Process: “The subregional study groups, and the TOPs that comprise the subregional study groups and, in consultation with the RC, are responsible for determining the studies to be performed for a given season. The study selection process is encouraged to should be collaborative, and should be based on the greatest reliability need, given the resources available.”
Line 147 - 148, clarify advisory role of the Seasonal Coordination Process: “Some considerations for determining the studies to be performed may include the following:”
Line 164 – 165, clarify how N-1-1 and N-1-2 operating conditions are within scope of the Seasonal Coordination Process: “5. It is determined that there is a need to assess N-1-1 and N-1-2 operating conditions to identify potential long-term IROLs.”
Line 169 – 171, clarify current WECC RAS Reliability Subcommittee (RASRS) and future RC review and coordinated study roles for RAS approval and retirement to avoid duplicative studies: “8. Coordinated WECC RASRS or RC studies of Nnew RAS or other automatic mitigation schemes approvals or retirements that do not consider have been employed or retired that have an impact to stability limitations or have an impacts to coordinated TOP-to-TOP operations
Line 184 – 186, clarify advisory role of the Seasonal Coordination Process: ”After the studies to be performed have been determined, the subregional study group needs to should develop and document the study plan. The study plan may address as many of the specifics for the study including:”
Line 195 – 196, clarify why included in and advisory roles of Seasonal Coordination Process: “8. Description of how any potential long-term IROLs for N-1-1 and N-1-2 conditions are may be identified.”
iLine197 - 201, clarify advisory role of the Seasonal Coordination Process: “The subregional study groups are encouraged expected to agree on their respective study plans prior to moving forward to the next step. Where there is a common transmission path between subregions that is being
4
studied by either subregion, the assumptions and specifics of this path study should be are encouraged to be coordinated and agreed to upon by the respective subregions prior to study commencement.”
Line 202 -203, clarify advisory role of the Seasonal Coordination Process: “When documenting the study plan for a given study, the subregional study groups should adhereto may consider the Seasonal Study Plan Outline in Appendix II.
Line 205 – 215, allow for the uncertainty of operating case development, and clarify advisory role of the Seasonal Coordination Process: “The study plan is expected to specify the WECC operating case(s) to be used in the study. Once that decision is made, the TOPs within the subregional study groups need to review the WECC operating cases(s) to ensure accuracy and to set up the initial conditions for the cases involved. A single system-wide seasonal operating case may be developed for the Western Interconnection. The subregional study group is responsible for coordinating TOP activities to ensure review the accuracy of the case, initial conditions, and that case finalization occurs in a coordinated and timely manner. Operating Case development is encouraged needed even if there are no studies performed for that season. For example, if the subregional study group determines that there is no need to perform a spring study, the subregional study group should may still coordinate the spring operating case and make changes as necessary to provide an accurate case for TOP’s subsequent use as a starting case for outage coordination and OPAs performed for the spring season.”
Line 217 – 221, clarify advisory role of the Seasonal Coordination Process: “The study plan is expected to specify which entities are responsible for performing the various aspects of the study. The study plan outline in Appendix II should includes a timeline and milestone dates for completing the study. As part of this step, the entities involved in performing the studies are expected encouraged to meet the schedules and to keep the subregional study group chair updated on their progress.”
Line 223 – 228, clarify advisory role of the Seasonal Coordination Process: “After the studies are completed, the study results should be are reviewed and accepted by the subregional study group members. Any study results that impact other subregional study groups are encouraged to should include those groups in the review and acceptance. It is expected that the Studies and subsequent reviews might occur in an iterative fashion. Care should be taken Subregional study groups are encouraged to allow time for study iterations in the overall study timeline.”
Line 233 – 235, clarify advisory role of the Seasonal Coordination Process: “Each subregional study group is encouraged to should review the Seasonal Operations Planning Study Checklist as part of conducting the studies and creating the final study report (see Appendix IV).”
Line 237 – 240, clarify advisory role of the Seasonal Coordination Process: “Often the seasonal studies may require the development of new Operating Plans or the revision of existing Operating Plans3. Once the studies have been reviewed and accepted, the impacted TOPs are expected encouraged to collaborate to develop or revise Operating Plans as necessary.”
Line 241 -243, clarify advisory role of the Seasonal Coordination Process: “Each subregional study group is encouraged toshould review the Seasonal Operations Planning Study Checklist as part of conducting the studies and creating the final study report (see Appendix IV).”
Line 245 – 249, reading ease and clarifying advisory role of the Seasonal Coordination Process: “Since the scope of the RC Seasonal Operations Planning Coordination Process includes reliability
5
issues that may require TOP-to-TOP coordination, it is imperative recommended that the TOPs involved perform collaborate and coordinate their tasks with coordination at the forefront. The following list of actions describes some of the possible coordination responsibilities associated with the RC Seasonal Operations Planning Coordination Process:”
Line 261-263, align with contemplated ECC relief options and clarifying advisory role of the Seasonal Coordination Process: “5. Coordinated Operating Plans have been developed and agreed upon by impacted TOPs. Where applicable, TOP options for providing relief obligations (e.g., scheduling methodsology(ies), and curtailment plans, etc.) are to may be addressed as part of the Operating Plan.”
Line 268 – 273, clarify advisory role of the Seasonal Coordination Process: “7. Where disagreements arise and can are not be reconciled by the beginning of the season, the impacted TOPs Operating Plans may will default to interim conservative limits – or other agreed upon limits – and applicable Operating Plans for use while awaiting dispute resolution. If the issue is not resolved to the satisfaction of the disagreeing parties, the TOPs are expected encouraged to work with Peak to assist in resolveing the issue.”
Line 274 – 278, simplify and clarify advisory role of the Seasonal Coordination Process:
“In several locations in this document, tThe term “impacted entity” or “impacted TOP” is used to identify indicate the need to the parties for follow-up, coordinateion and resolve ution of any reliability issues uncovered by a study or analysis. Impacted TOPs are also to be consulted in the development of Operating Plans for ensuring acceptable reliable system performance.
Line 279 – 288, clarify studies identify “potential” conditions, facilities may be “jointly operated” or “jointly owned” and advisory role of the Seasonal Coordination Process: “The following are some of the guidelines TOPs may use to identify impacted entities:
1. Studies in one TOP Area identify potential SOL exceedance in that TOP Area or in another TOP Area requiring TOP-to-TOP coordination to address the SOL exceedance.
2. Study results reveal simultaneous interaction that may resulting in a nomogram relationship of conditions in one TOP Area versus with those in another TOP Area.
3. In the course of base case adjustments in preparation for a study, potential SOL exceedances are observed in another TOP Area.
4. Studies involve transmission paths or BES Facilities that are jointly owned or operated by multiple TOPs.”
Line 292 – 294, clarify the advisory role of the Seasonal Coordination Process: “The RC Seasonal Operations Planning Coordination Process requires encourages peer review and acceptance of studies performed as part of the RC Seasonal Operations Planning Coordination Process.”
Line 296 -297, clarify the advisory role of the Seasonal Coordination Process: “Acceptance can may be granted when peer review is deemed successful according to the following:”
Line 308 – 312, clarify the advisory role of the Seasonal Coordination Process: “Each subregional study group is expected encouraged to implement a study acceptance process that provides TOP representatives the opportunity to voice outstanding reliability issues. This acceptance process is intended to ensure acknowledges that reliability issues impacting more than one TOP have been adequately addressed and that proper coordination has taken place prior to the beginning of the operating season.”
Line 314 -317, clarify the advisory role of the Seasonal Coordination Process: “Satisfactory resolution of outstanding reliability issues is in the interest of BES reliability in the Peak RC Area.
6
Where reliability concerns/issues are raised, the subregion is expected encouraged to initiate a process to satisfactorily address each reliability issue.”
Line 318 321, clarify the “majority”, “minority” or “dissenting” roles and the advisory role of the Seasonal Coordination Process: “If attempts to reach unanimity consensus remain unachievable, the subregion is expected encouraged to document each of the majority and minority positions and bring these to the attention of the Peak RC to help facilitate resolution. EachTOPs for the majority and dissenting positions TOP isexpected are encouraged to be prepared and present their cases to Peak RC as part of these discussions.”
Line 324 – 326, clarify the advisory role of the Seasonal Coordination Process: “Four subregional study groups are recognized by Peak RC as being having responsibleility for performing, coordinating and accepting seasonal studies in accordance with the RC Seasonal Planning Coordination Process. These study groups are:”
Line 335 – 342, clarify the RC does not govern and the advisory role of the Seasonal Coordination Process: “The RC Seasonal Operations Planning Coordination Process is voluntary. The RC does not govern the subregional study groups. These subregional study groups are not governed by Peak RC. They each may have their own reporting and governance structure and their own responsibilities in accordance with their respective authorities. However, all four subregional study groups have are encouraged to use the RC Seasonal Operations Planning Coordination Process in common as guidance. , i.e., eEach of the four subregional study groups may are to perform the functions specified in the RC Seasonal Operations Planning Coordination Process at a minimum, and are free to perform studies beyond the RC Seasonal Operations Planning Coordination Process as they are required or as they see fit.”
Line 347 -348, clarify the advisory role of the Seasonal Coordination Process: “The expected roles and responsibilities of subregional study groups may include the following:”
Line 354 – 356, clarify the RC does not govern and the advisory role of the Seasonal Coordination Process: “2. Coordinate with the TOP representatives in the subregional study group and the RC to determine the studies that add real, tangible value to operations reliability, and are to be performed for a given season and the system conditions under which they should be studied.”
Line 359 – 361, clarify the advisory role of the Seasonal Coordination Process: “4. Ensure that Coordinate base cases are to be reviewed and prepared for the studies.
5. Review and coordinate seasonal studies with TOPs internal and external to the subregional study group to verify that the RC Seasonal Operations Planning Coordination Process has been followed.”
Line 364 – 374, clarify that the RC does not govern and the advisory role of the Seasonal Coordination Process: “7. Coordinate studies to aAddress reliability concerns and issues raised by TOPs internal and external to the subregional study group
8. Absent a consensus regarding study results, coordinate the documentation of the majority and minority positions.
9. Ensure Complete studies are completed in time for developing coordinated Operating Plans.
10. Provide Coordinate technical study support, including with Peak RC, and coordination as requested by the TOPs and Peak RC in support of the development of Operating Plans.
11. Ensure that Post the resulting documentation is posted on the peakrc.org website.
Examples of this such documentation include study plans, study reports and Operating Plans.”

Line 380, clarify the advisory role of the Seasonal Coordination Process: “The expected roles and responsibilities of the TOPs may include the following:”
Line 385 -386, clarify that the RC does not govern and the advisory role of the Seasonal Coordination Process: “3. Coordinate with Peak RC Contribute to determineing the studies that are to be performed for a given season and the system conditions under which they should be studied.”
Line 389 – 401, clarify the advisory role of the Seasonal Coordination Process: “5. Review WECC operating cases and make necessary adjustments to ensure that the cases for are accuratecy and ready for use for the studies being performed for the season. Additionally, TOPs should provide input to coordinate with their respective Transmission Planners when the WECC operating base cases are being developed.
6. Ensure that Perform the seasonal studies performed as part of the RC Seasonal Operations Planning Coordination Process are in accordance with the RC’s SOL Methodology.
7. Ensure that Prepare Operating Plans developed as part of the RC Seasonal Operations Planning Coordination Process to support the level of operational reliability described consistent with the RC’s SOL Methodology.
8. Consistent with the timelines in Appendix VI, Uupdate and publish the list of Always Credible Multiple Contingencies for its TOP Area for use in seasonal studies.”
Line 403 409, clarify there may be impacts between TOPs whether small or large, and the advisory role of the Seasonal Coordination Process: “While the level of involvement in the RC Seasonal Operations Planning Coordination Process of smaller TOPs may be significantly less than that of larger TOPS, it is incumbent on Ssmaller TOPs are encouraged to participate in their corresponding subregional study group, to the extent practicable, to maintain an awareness of any impacts the seasonal studies might have on their TOP Area or their impact on other TOP Areas. Depending on the specifics of a given study plan, smaller TOPs could have a more significant role in performing the studies in accordance with the RC Seasonal Operations Planning Coordination Process.”
Line 412, clarify the advisory role of the Seasonal Coordination Process: “The expected roles and responsibilities of Peak RC may include the following:”
Line 415 – 426, clarify that the RC does not govern and the advisory role of the Seasonal Coordination Process: “2. Coordinate with the subregional study groups to determine the studies that are may be performed for a given season and the system conditions under which they should may be studied.
3. Participate in the development of study plans to ensure that the studies will achieve the objectives of the RC Seasonal Operations Planning Coordination Process..
4. Ensure that the Provide guidance on consistency of study plans and studies performed for identifying risks of instability, Cascading or uncontrolled separation and for establishing stability limits and the identification of potential IROLs are executed in accordance with the RC’s SOL Methodology.
5. Ensure that Provide guidance on the consistency of Operating Plans developed as part of the RC Seasonal Operations Planning Coordination Process support the level of reliability described in with the RC’s SOL Methodology.”
Line 429 – 433, clarify that the RC does not govern and the advisory role of the Seasonal Coordination Process: “7. Participate as necessary with the subregional study group chairs to discuss and approaches to resolve any outstanding reliability issues prior to each operating season.
8
8. Facilitate dispute resolution of seasonal studies or processes for reliability issues related to stability limits and or identification of potential IROLs. It is not the responsibility of the RC to resolve contractual or commercial issues that may exist between TOPs.”
Line 442, clarify base case application: “O. Operating Base Case Development”
Line 443 – 448, recommend deleting as it appears to duplicate prior section concerning WECC role in developing base case: “Development and approval of operating base cases (in both PSLF4, PSS/E5 and PowerWorld formats)6 used for seasonal studies is coordinated by the WECC RE. Since TOPs must use the approved operating base cases as starting power system conditions, it is important that these base cases (power flow and dynamics) are published by the WECC RE in time to implement seasonal studies per the Seasonal Coordination Timelines in Appendix VI.”
Line 449 – 452, clarify the advisory role of the Seasonal Coordination Process: “Depending on the studies being undertaken, TOPs are expected encouraged to coordinate with impacted entities to adjust the approved operating base cases to reflect the specific conditions being studied. Coordinated base cases must are encouraged to be completed in a timely manner consistent with the timelines in Appendix VI.”
Line 457 – 460, provide “consistent with” the SOL methodology and clarify the advisory role of the Seasonal Coordination Process: “See the RC’s SOL Methodology for instructions on the selection of Always Credible multiple Contingences (MC) and Conditionally Credible MCs. It is expected that Ssingle Contingencies, Always Credible MCs, and applicable Conditionally Credible MCs that are consistent with the RC SOL Methodology comprise the Contingencies to that may be included in the seasonal studies.”
Line 462 -464, clarify the advisory role of the Seasonal Coordination Process: “The subregional study groups may select applicable Contingencies based on system knowledge, prior experience and engineering judgement.”
Line 467 – 472, clarify the advisory role of the Seasonal Coordination Process: “Planned transmission or generation Facility outages that span the entire season must are encouraged to be removed from service in the operational base case(s) for accuracy. While the RC Seasonal Operations Planning Coordination Process is not intended to be an extension of the RC Outage Coordination Process, subregions have discretion to include certain prior outages in a given study. Any outages included in the studies must should be listed in the study plan and in the final study report.”
Line 474 – 483, clarify the advisory role of the Seasonal Coordination Process, including simply description of discretion to add seasonal study: “The seasons eligible for study as part of the RC Seasonal Operations Planning Coordination Process include summer, winter and spring, the seasons provided in Appendix VI. If prior studies are deemed by the subregional study group to be sufficient for a given season, the subregion may determine that performing a new study is not warranted. While fall studies have not historically been performed as part of coordinated seasonal planning studies, subregional study groups might see a need to perform fall studies. If this is the case, the subregioinal study group should determine the appropriate WECC case(s) to be used and should establish their own timeline since fall studies are not addressed in the Study Timeline in Appendix VI. The subregional study groups are not obligated to create or may provide for a fall seasonal case,
9
including determining the appropriate base case and establishing timelines for completing the study.”
Line 486 – 491, minimize repetition and duplication: “One of the primary objectives of the RC Seasonal Operations Planning Coordination Process is to identify any risks for instability, Cascading or uncontrolled separation, applied consistent with the RC’s SOL Methodology. See section F, entitled “Scope of the RC Seasonal Operations Planning Coordination Process,. “provides a description of this aspect of the RC Seasonal Operations Planning Coordination Process. The description of instability Cascading of uncontrolled separation provided in the RC’s SOL Methodology should be applied.”
Line 492 – 494, clarify the advisory role of the Seasonal Coordination Process: “It is imperative that Tthe study reports specifically call out any instability, Cascading or uncontrolled separation identified in the seasonal planning studies. The study reports, as outlined in Appendix III, should specifically are encouraged to address the following: “
Line 501 - 502, clarify the condition studied: “4. The amount of load that may potentially be is lost due to instability, Cascading or uncontrolled separation, if it is possible to make this determination.”
Line 503 – 506, clarify focus on implementation of “automatic schemes” resulting in Load Loss: “5. Any Remedial Action Scheme action, under voltage load shedding (UVLS) action, under frequency load shedding (UFLS) action, interruption of Firm Transmission Service or Non-Consequential or other automatic scheme that may potentially result in Load Loss to address the instability, Cascading or uncontrolled separation.”
Line 506 footnote 7 text, clarify consistency with SOL Methodology and advisor role of the Seasonal Coordination Process: “If any of these measures were taken to address instability, Cascading or uncontrolled separation, the report needs to is encouraged to indicate that these automatic schemes were responsible for the avoidance of the instability, Cascading or uncontrolled separation, consistent with the RC SOL methodology,. It is critical that there is to have an awareness that without these schemes, instability, Cascading or uncontrolled separation could result.”
Line 513 – 517, clarify the advisory role of the Seasonal Coordination Process: “To ensure that the RC Seasonal Operations Planning Coordination Process is executed complete the seasonal studies in an orderly and timely manner, the timelines stipulated in Appendix VI apply are provided. TOPs and subregional study groups are expected encouraged to take these timelines into consideration when coordinating subregional study group activities such as developing base case(s), any study iterations and report acceptance processes.”
Line 519, 521, clarify which documents are controlled: “Only Tthe online electronic copy of the RC Seasonal Operations Planning Coordination Process is the only controlled copy and is posted on the PeakRC.com site is controlled. However, Printed copies may be out of date.
