should explain why the filing parties believe their current practices violate the standards and why their practices should be considered equal or superior to the standards in preventing overscheduling while providing for more flexibility or other benefits in scheduling. We urge NAESB to consider the issues raised by Bonneville and the ISO/RTO Council and whether revisions to these standards are warranted. The Commission also is mindful of the consideration of the potential benefits of maximizing the use of transmission when appropriate, without compromising reliability, and maintaining flexibility to maximize transmission utilization as conditions change, and has scheduled a workshop that may consider these issues.40
3. Changes to the Regulatory Text a. Background
jbell on DSKJLSW7X2PROD with RULES

33. The Commission sought comment on proposed additional regulatory text in 18 CFR 37.6 information to be posted on the OASIS stating that transmission provider ATC calculations must be transparent, consistent, and not unduly discriminatory or preferential.
Specifically, the Commission proposed to make the revisions indicated below to the regulatory text in 18 CFR
37.6b2i:
Information used to calculate any posting of ATC and TTC must be dated and time-stamped and all calculations shall be performed according to consistently applied methodologies referenced in the Transmission Providers transmission tariff and shall be based on Commission-approved Reliability Standards, business practice and electronic communication standards, and related implementation documents, as well as current industry practices, standards and criteria.
Transmission Providers shall calculate ATC and TTC in coordination with and consistent with capability and usage on neighboring systems, calculate system capability using factors derived from operations and planning data for the time frame for which data are being posted including anticipated outages, and update ATC and TTC calculations as inputs change. Such calculations shall be conducted in a manner that is transparent, consistent, and not unduly discriminatory or preferential.41

34. The NOPR explained that this proposed regulation, in conjunction with the WEQ023 Modeling Business Practice Standards, will help ensure that all transmission customers will be treated fairly when seeking alternative power supplies, and will provide for comparable and not unduly discriminatory or preferential treatment of native load customers and transmission service customers. 42 The Commission also sought comment on whether it should develop new regulations outside of the NAESB
standards development process to maintain the current level of detail related to ATC calculations; if so, what level of detail those regulations should have. 43
b. Comments 35. Four commenters oppose the Commissions proposed changes to the regulatory text. No commenters filed in support of the proposal. Bonneville and the Edison Electric Institute EEI assert that the Commissions proposed language is unnecessary. Bonneville further asserts that the regulatory changes circumvent the NAESB process sanctioned by the Commission for the development of standards, and that the Commissions regulations are not the appropriate place to address technical details involving the calculation of ATC
and TTC. In particular, Bonneville maintains that the Commissions proposed language includes ambiguous references to technical concepts such as factors derived from operations and planning data in the calculation of ATC and TTC.44 EEI contends that revisions should occur through NAESBs standard development process, and that the directives in Order No. 890 and related provisions in the pro forma OATT are sufficient to ensure that ATC calculation is consistent and non-discriminatory. EEI also notes that in Order No. 890, the Commission acknowledged its reliance on NAESB for the development of business practice standards.45
36. The ISO/RTO Council disagrees with the concerns expressed in the NOPR about the opportunity for discriminatory practices and transmission provider discretion in the 42 WEQ Version 003.3 NOPR, 172 FERC 61,047
at P 49 citing Mandatory Reliability Standards for the Calculation of Available Transfer Capability, Capacity Benefit Margins, Transmission Reliability Margins, Total Transfer Capability, & Existing Transmission Commitments & Mandatory Reliability Standards for the Bulk-Power Sys., Order No. 729, 74 FR 64884 Dec. 8, 2009, 129 FERC

calculation of ATC and AFC, stating that the WEQ023 Modeling Business Practice Standards were extensively vetted through NAESBs industry-wide standards development process where any comments received regarding the lesser degree of detail in the standards were successfully addressed prior to NAESB ratification. 46 The ISO/RTO
Council contends that the WEQ023
Modeling Business Practice Standards ensure non-discriminatory practices and limit transmission provider discretion by requiring each transmission service provider to publish its ATC calculation methodology, and to describe its methodology in its ATC implementation document such that, given the same information used by the transmission service provider, the ATC calculations are reproducible and can be validated.47
37. Similarly, Open Access Technology International, Inc. OATI
maintains that the NAESB standards development process is the best way to draft standards through an open, transparent, and industry participant driven process. It states that standards developed through this process would help the Commission avoid the imposition of unintentional and unnecessary regulatory changes.48 All four commenters agree that, if the Commission determines that the WEQ
023 Modeling Business Practice Standards are insufficient, it should encourage NAESB to provide additional details and specific standards to address those shortcomings.
c. Commission Determination 38. We adopt the NOPR proposal, with certain revisions. We recognize that commenters oppose adding these criteria to the Commissions regulations, but after consideration of their arguments we continue to believe that revisions to the Commissions regulations are necessary to ensure that transmission provider ATC calculations are transparent, consistent with anticipated system conditions and outages for the relevant timeframe, and not unduly discriminatory or preferential. However, in response to concerns raised in comments, we will not include detailed technical criteria in the regulations, but we will instead include the fundamentals of Order No.
890 requirements for calculating ATC, which is consistent with what the Commission proposed in the NOPR. The 46 ISO/RTO
