Order No. 729-A

Order on Clarification

(Issued May 5, 2010) 1. In this order, the Commission grants several requests for clarification of Order No. 729,\1\ which approved and directed modification of six Modeling, Data, and Analysis (MOD) Reliability

Standards submitted to the Commission for approval by the North

American Electric Reliability Corporation (NERC), the Commission- certified Electric Reliability Organization (ERO) for the United

States.\2\ As discussed below, the Commission clarifies the implementation timeline for these Reliability Standards as well as certain directed modifications.

1. Background 2. On November 24, 2009, the Commission issued a Final Rule in this proceeding that approved the six MOD Reliability Standards submitted to the Commission by the ERO. The approved Reliability Standards pertain to methodologies for the consistent and transparent calculation of available transfer capability or available flowgate capability.

   Pursuant to section 215(d)(5) of the FPA \3\ and section 39.5(f) of our regulations, the Commission directed the ERO to develop certain modifications to the MOD Reliability Standards. The Commission also directed NERC to retire the existing MOD Reliability Standards replaced by the versions approved in the Final Rule once the new versions became effective.

   \3\ 16 U.S.C. 824o(d)(5) (2006).

   3. On December 23, 2009, American Public Power Association (APPA) and Transmission Access Policy Study Group (TAPS), Duke Energy

   Carolinas, LLC (Duke), Edison Electric Institute (EEI), ISO New England

   (ISO-NE), and NERC filed timely requests for clarification.

2. Discussion

   1. Implementation Schedule 4. In the Final Rule, the Commission directed that the Reliability

      Standards become effective according to the schedule proposed by the

      ERO.\4\ Thus, the Commission stated that the MOD Reliability Standards shall become effective on the first calendar quarter that is twelve months beyond the date that the Reliability Standards are approved by all applicable regulatory authorities. The Commission found that this implementation schedule struck a reasonable balance between the need for timely reform and the needs of transmission service providers and transmission operators to make adjustments to their calculations of available transfer capability, capacity benefit margin and transfer reserve margin. In response to comments on its notice of proposed rulemaking, the Commission clarified that, under this plan, the

      Reliability Standards shall become effective on the first day of the first quarter occurring 365 days after approval by all applicable regulatory authorities. Approval by the Commission would be effective 60 days after the date of publication of the Final Rule in the Federal

      Register.\5\

      \4\ Order No. 729, 129 FERC ] 61,155 at P 95.

      \5\ Id.

      Requests for Clarification 5. Several petitioners requested clarification of the implementation schedule. If the Commission intended approval of the MOD

      Reliability Standards to be effective upon their approval of all regulatory authorities, including the applicable Canadian provinces,

      APPA and TAPS, along with ISO-NE, ask the Commission to clarify a process to keep the Commission and industry informed on the status of the required regulatory approval process. By contrast, EEI asks the

      Commission to clarify that the MOD Reliability Standards will become effective in the United States no earlier than the first

      Page 26058

      day of the first quarter occurring 365 days after the Commission approves the MOD Reliability Standards. 6. NERC also requests clarification and provides some insight into its proposed implementation schedule. NERC explains that the term ``all applicable regulatory authorities,'' as it is used in the MOD

      Reliability Standards, includes the Commission and the relevant regulatory authorities in the Canadian provinces. NERC states that, when it developed the implementation schedule, all participants anticipated that the processes for approving the MOD Reliability

      Standards in all jurisdictions would result in approvals that occurred at roughly the same time. However, according to NERC, the processes for approval of Reliability Standards are in various stages of development in various jurisdictions. Accordingly, NERC requests that the

      Commission clarify that the MOD Reliability Standards shall become effective within the United States no earlier than the first day of the first quarter occurring 365 days after the publication of Order No. 729 in the Federal Register.

      Commission Determination 7. The Commission agrees that, without further clarification about regulatory approvals in the Canadian provinces, the approved implementation schedule is not determinative as to the effective date of the MOD Reliability Standards within the United States. Without a clear process for informing entities of the approval by all appropriate regulatory authorities, the implementation schedule presents some compliance risks. NERC has indicated that it would support implementation of the MOD Reliability Standards within the United

      States as of the first day of the first quarter occurring 365 days after the publication of Order No. 729 in the Federal Register. The

      Commission agrees that this implementation schedule is appropriate.

      Accordingly, the Commission clarifies that the MOD Reliability

      Standards shall become effective within the United States as of the first day of the first quarter occurring 365 days after the publication of Order No. 729 in the Federal Register, i.e., January 1, 2011. 8. Compliance with these MOD Reliability Standards requires an exchange of information and data among neighboring transmission service providers. In some instances, for example, a transmission service provider within the United States may need to exchange information and data with a neighboring transmission service provider located in a jurisdiction where the Reliability Standard is not yet enforceable. In this situation, the transmission service provider within the United

      States shall share information with the transmission service provider located in another jurisdiction pursuant to the requirements of these

      MOD Reliability Standards. Nevertheless, the transmission service providers and transmission operators within the continental United

      States who must rely on information and data from utilities located in another country to comply with these Reliability Standards shall not be penalized solely for the failure of a utility located in another jurisdiction to provide such information and data, until such time that the MOD Reliability Standards become mandatory in that foreign jurisdiction. 9. So that the Commission is informed about international approval of these MOD Reliability Standards, we direct the ERO to file notices with the Commission when any other applicable regulatory authority approves any or all of the MOD Reliability Standards approved by the

      Commission in Order No. 729. The ERO also must post notice of such approval on its Web site.

   2. Audit Scope 10. In the Final Rule, the Commission directed the ERO to conduct an audit to measure compliance with the MOD Reliability Standards. In response to comments on its notice of proposed rulemaking, the

      Commission clarified that these audits are not intended to address the competitive effects of these MOD Reliability Standards.\6\ The

      Commission further stated that the audits should review each component of available transfer or flowgate capability, including the transmission service provider's calculation of capacity benefit margin and transmission reliability margin, for transparency and verifiability to ensure compliance with the MOD Reliability Standards.\7\ The

      Commission explained that such an audit is consistent with Requirement

      R3.1 of Reliability Standard MOD-001-1, which requires transmission service providers to include in their available transfer capability implementation documents information describing how the selected methodology (or methodologies) has been implemented. Under Requirement

      R3.1, transmission service providers are to provide enough detail for the Commission and others to validate the results of the calculation given the same information used by the transmission service provider.

      \6\ Order No. 729, 129 FERC ] 61,155 at P 106.

      \7\ Id.

      Request for Clarification 11. Duke contends that, although Requirement R3.1 of MOD-001-1 may be broad enough to permit the ERO to audit capacity benefit margin and transfer reliability margin calculation to determine if they can be validated, Reliability Standards MOD-004-1 and MOD-008-1 are not the source for such authority. Accordingly, Duke asks the Commission to clarify that the audits of MOD-004-1 and MOD-008-1 are to be limited to compliance with the explicit requirements of those Reliability

      Standards.

      Commission Determination 12. Reliability Standard MOD-001-1 establishes foundational requirements that oblige entities to select a methodology for calculating available transfer or flowgate capability and then make the appropriate calculations. Reliability Standards MOD-004-1 and MOD-008-1 establish the methodologies for calculating capacity benefit margin and transmission reliability margin, respectively. The NERC Glossary of

      Terms Used in Reliability Standards (NERC Glossary) defines available transfer capability as ``Total Transfer Capability less Exiting

      Transmission Commitments (including retail customer service), less a

      Capacity Benefit Margin, less a Transmission Reliability Margin, plus

      Postbacks, plus counterflows.'' \8\ Thus, both capacity benefit margin and transmission reliability margin are integral components of any available transfer or flowgate calculation.

      \8\ See NERC Glossary, available at: http://www.nerc.com/docs/ standards/rs/Glossary_2009April20.pdf.

      13. Under Requirement R3.1 of MOD-001-1, a transmission service provider must include in its implementation documentation:

      ``[i]nformation describing how the selected methodology (or methodologies) has been implemented, in such detail that, given the same information used by the Transmission Service Provider, the results of the [available transfer capability] or [available flowgate capability] calculations can be validated.\9\

      \9\ Reliability Standard MOD-001-1, Requirement R3.1.

      Because capacity benefit margin and transfer reliability margin are integral components of any available transfer or flowgate capability calculation, we believe that, for an entity to validate the results of an available transfer or flowgate capability calculation, the calculations of capacity benefit margin and transfer reliability margin must also

      Page 26059

      be detailed in the implementation document with such detail that they can be validated. Thus, the Commission clarifies that the calculations of capacity benefit margin and transfer reliability margin, performed under MOD-004-1 and MOD-008-1 respectively, are properly audited under

      Requirement R3.1 of MOD-001-1.

   3. Benchmarking 14. In the Final Rule, the Commission directed the ERO to develop benchmarking and updating requirements for the MOD Reliability

      Standards to measure modeled available transfer and flowgate capability values against actual values.\10\ The Commission stated that such requirements should specify the frequency for benchmarking and updating the available transfer and flowgate capability values and should require transmission service providers to update their models after any incident that substantially alters system conditions, such as generation outages.\11\

      \10\ Order No. 729, 129 FERC ] 61,155 at P 162.

      \11\ Id.

      Request for Clarification 15. Duke states that, in Order No. 693, the Commission directed the

      ERO to modify Reliability Standard MOD-014-0 to include a requirement for validating models against actual system results. Duke states that the Commission reinforced this requirement in Order No. 890-A, holding that the models used by the transmission provider to calculate available transfer capability, and not actual available transfer capability values, must be benchmarked. Duke requests that the

      Commission clarify that its directive in Order No. 729 to develop benchmarking and updating requirements is the same as the directives in

      Order Nos. 693 and 890-A, and is not intended to require a different form of benchmarking.

      Commission Determination 16. The Commission clarifies that the directive in Order No. 729 to develop benchmarking and updating requirements is related to the directives in Order Nos. 693, 890, and 890-A. In Order No. 693, the

      Commission directed modification of Reliability Standard MOD-014-0 to include a requirement that the models developed under the Reliability

      Standard be validated against actual system responses and that the maximum discrepancy between the model results and the actual system response should be specified in the Reliability Standard.\12\

      Similarly, in Order No. 890, the Commission directed public utilities, working through NERC, to modify certain MOD Reliability Standards to incorporate requirements for the periodic review and modification of certain models.\13\ In Order No. 890-A, the Commission clarified this directive by stating that the models used by the transmission provider to calculate available transfer capability, and not actual available transfer capability values, must be benchmarked.\14\

      \14\ Order No. 890-A, FERC Stats. & Regs. ] 31,261 at P 99.

      17. The Commission remains concerned about the accuracy of the models used to calculate available transfer capability. Accordingly, in

      Order No. 729, the Commission directed the ERO to develop benchmarking and updating requirements to measure the results of the available transfer and flowgate calculations against actual values. The

      Commission's directive to develop benchmarking and updating requirements stems from the same concerns raised in Order Nos. 693, 890, and 890-A. The benchmarking and updating requirements directed in

      Order No. 729 are not intended to require a different form of benchmarking than required under those prior orders.

   4. Treatment of Network Resource Designations 18. In the Final Rule, the Commission found that Reliability

      Standards MOD-028-1 and MOD-029-1 failed to address the directive in

      Order No. 693 to specify how transmission service providers should determine which generators should be modeled in service when calculating available transfer capability.\15\ Specifically, with regard to MOD-028-1, the Commission noted that Requirement R3.1.3, which addresses designated network resources, governs the calculation of total transfer capability, not existing transmission commitments.

      The Commission stated that the only information provided as to the effect of designating and undesignating a network resource on existing transmission commitments is in Requirement R8, which merely states that

      ``the firm capacity set aside for Network Integration Transmission

      Service'' will be included. Accordingly, the Commission directed the

      ERO, pursuant to section 215(d)(5) of the FPA and section 39.5(f) of its regulations, to develop a modification to MOD-028-1 and MOD-029-1 to specify that base generation schedules used in the calculation available transfer capability will reflect the modeling of all designated network resources and other resources that are committed to or have the legal obligation to run, as they are expected to run, and to address the effect on available transfer capability of designating and undesignating a network resource.

      \15\ Order No. 729, 129 FERC ] 61,155 at P 171 (citing Order No. 693, FERC Stats. & Regs. ] 31,242 at P 119).

      Request for Clarification 19. Duke contends that the Commission's directive requiring additional specificity regarding the effect of designating and undesignating a network resource on existing transmission commitments is inappropriately focused on modifications to Requirement R8 of MOD- 028-1. Duke states that which requirements need to be amended to include the desired additional specificity will be dependent on which components of available transfer capability are impacted by the base model and network resource designations and undesignations. According to Duke, the Commission erred in stating that existing transmission capacity includes firm capacity set aside for network integration transmission service. According to Duke, within MOD-028-1, the relationship between capacity set aside for network integration transmission service and existing transmission commitment is a narrower concept than the Commission presents in Order No. 729. Accordingly,

      Duke recommends that the Commission should not expect Requirement R8 of

      MOD-028-1 to be modified as a result of an effort to include the additional specificity and requests that the Commission clarify that the added specificity should be included in whichever Requirement(s) are relevant and appropriate.

      Commission Determination 20. In the Final Rule, the Commission did not intend to direct the

      ERO to necessarily develop a modification to Requirement R8 of MOD-028- 1. The ERO may develop a modification to another appropriate requirement of MOD-028-1 to capture the additional specificity required regarding the effect

      Page 26060

      of designating and undesignating a network resource on existing transmission commitments or, as Duke notes, any other relevant component of available transmission capacity. Nevertheless, any modification developed to fulfill this requirement must specify how transmission providers should model base generation dispatch in a consistent manner that includes all designated network resources and other resources that are committed to or have the legal obligation to run, as they are expected to run.\16\

      \16\ See Order No. 693, FERC Stats. & Regs. ] 31,242 at P 1041.

   5. Updates To Dispatch Model Following Material Changes 21. In the Final Rule, the Commission determined that, to be useful, hourly, daily, and monthly available transfer and flowgate capability values must be calculated and posted in advance of the relevant time periods.\17\ The Commission found that Requirement R8 of

      MOD-001-1 and Requirement R10 of MOD-030-2 require that such posting will occur far enough in advance to meet this need. Nevertheless, in light of concerns raised by commenters, the Commission directed the ERO to develop modifications to MOD-001-1 and MOD-030-2 to clarify that material changes in system conditions will trigger an update whenever practical.\18\

      \17\ Order No. 729, 129 FERC ] 61,155 at P 179.

      \18\ Id.

      Request for Clarification 22. Duke states that it agrees that material changes should trigger an update whenever practical, but admonishes that such a requirement is too vague to be enforceable, let alone auditable, by the ERO due to differing interpretations of the phrases ``material changes'' and

      ``whenever practical.'' Accordingly, Duke requests that the Commission provide further clarity to the ERO as to the desired modifications.

      Commission Determination 23. The Commission agrees that it could be difficult in some instances to enforce a requirement that hinges upon such phrases as

      ``material changes'' and ``whenever practical.'' Nevertheless, we believe that such modifications would be useful to ensure timely updates of available transfer or flowgate capability values. If the ERO is unable to modify the requirements of MOD-001-1 and MOD-030-2 to incorporate such language in a manner that sets clear criteria or measures of whether an entity is in compliance with the relevant

      Reliability Standard or cannot otherwise identify specific changes in system conditions that require an update, the ERO must, at a minimum, include this language in its measures of compliance associated with those Reliability Standards.

   6. Managing the Use of Capacity Benefit Margins 24. In the Final Rule, the Commission determined that ISOs, RTOs, and other entities with a wide view of system reliability needs should be able to provide input into determining the total amount of capacity benefit margin required to preserve the reliability of the system.\19\

      The Commission pointed out, though, that Requirements R1.3 and R7 of

      MOD-004-1 already make clear that determination of need for generation capability import requirement made by a load-serving entity or resource planner are not final. The Commission added that the third bullet of both Requirements R5 and R6 explicitly list reserve margin or resource adequacy requirements established by RTOs and ISOs among the factors to be considered in establishing capacity benefit margin values for available transfer capability paths or flowgates used in available transfer or flowgate capability calculations. To ensure that the

      Reliability Standard clearly identifies how the transmission service provider will manage situations where the requested use of capacity benefit margin exceeds the capacity benefit margin available, the

      Commission directed the ERO to develop a modification to MOD-004-1 to clarify the term ``manage'' in Requirement R1.3.\20\

      \19\ Order No. 729, 129 FERC ] 61,155 at P 222.

      \20\ Id.

      Request for Clarification 25. Duke states that it understands the Commission's directive to require that the manner in which such a situation is managed should be transparent to all users in the relevant capacity benefit margin implementation document. Accordingly, Duke asks the Commission to clarify that it intended to direct the ERO to modify the Reliability

      Standard to require that transmission service providers explain in their capacity benefit margin implementation document their specific method for managing a situation where the requested use of capacity benefit margin exceeds the capacity benefit margin available, recognizing that each transmission service provider may have its own method.

      Commission Determination 26. In Order Nos. 890 and 693, the Commission emphasized that each load-serving entity has the right to request that capacity benefit margin be set aside, and to use transmission capacity set aside for that purpose, to meet its verifiable generation reliability criteria requirement.\21\ The Commission is concerned that Reliability Standard

      MOD-004-1 could allow a transmission service provider to calculate, allocate, and use capacity benefit margin in a way that impairs the reliable operation of the Bulk-Power System. Under the Reliability

      Standard, the transmission service provider is to ``reflect consideration'' of studies provided by load-serving entities and resource planners demonstrating a need for capacity benefit margin and

      ``manage'' situations where the requested use of capacity benefit margin exceeds the capacity benefit margin available. Reliability

      Standard MOD-004-1 places no bounds on this ``consideration'' and

      ``management'' and, for example, would permit a transmission service provider to make decisions regarding the use of capacity benefit margin based solely on economic considerations notwithstanding a demonstration of need for capacity benefit margin by a load-serving entity or resource planner.

      \21\ Order No. 693, FERC Stats. & Regs. ] 31,242 at P 1080; see also Order No. 890, FERC Stats. & Regs. ] 31,241 at P 259; Order No. 890-A, FERC Stats. & Regs. ] 31,261 at P 82.

      27. These concerns would be diminished if the transmission service provider's capacity benefit margin implementation document were sufficiently transparent to allow others to validate the method of managing capacity benefit margin. Accordingly, the Commission upholds its decision to direct the ERO to develop a modification that would clarify the term ``manage'' in Requirement R1.3. The Commission clarifies, however, that the ERO, through its Reliability Standards development process, should determine the manner in which this clarification is made.

3. Information Collection Statement 28. The Office of Management and Budget (OMB) regulations require that OMB approve certain information collection requirements imposed by an agency.\22\ The revisions to the information collection requirements for transmission service providers and transmission operators adopted in Order No. 729 were approved under OMB Control No. 1902-0244. This order clarifies these requirements in order to

   Page 26061

   more clearly state the obligations imposed in Order No. 729, but does not substantively alter those requirements. OMB approval of this order is therefore unnecessary. However, the Commission will send a copy of this order to OMB for informational purposes only.
