1 January 11, 2015 via efiling Kimberly D. Bose, Secretary Federal Energy Regulatory Commission 888 First Street N.E. Washington, DC Re: NorthWestern Corporation, Docket No. ER Revisions to Montana Open Access Transmission Tariff Dear Secretary Bose: Pursuant to Section 205 of the Federal Power Act 1 and Section of the Federal Energy Regulatory Commission s regulations, 2 NorthWestern Corporation d/b/a NorthWestern Energy submits proposed revisions to certain sections of its Montana Open Access Transmission Tariff (OATT). These changes are ministerial and are summarized in the attached table. NorthWestern Energy requests an effective date of March 12, 2016, for the proposed revisions. I. Background NorthWestern Energy is a public utility engaged in the generation, transmission, and distribution of electricity and the supply and transportation of natural gas. Its facilities are located primarily in Montana and South Dakota. In South Dakota, NorthWestern Energy is a transmission owner within the Southwest Power Pool, Inc. and has transferred functional control of a large portion of its electric transmission facilities there to SPP. In Montana, NorthWestern Energy is a transmission owner/operator and Balancing Authority Area operator within the Western Electricity Coordinating Council. NorthWestern Energy s Montana and South Dakota transmission facilities are not physically connected and are not in the same electric reliability region. Accordingly, NorthWestern Energy 1 16 U.S.C. 824d C.F.R N. Montana Avenue, # 205 Helena, MT O

2 maintains separate open access transmission tariffs for operations in each state. This filing concerns only NorthWestern Energy s Montana OATT. II. Description of and Justification for Tariff Revisions NorthWestern Energy respectfully requests the Commission approve the changes discussed below. These revisions do not affect or present changes to any Commission-approved rates or services; rather, they are ministerial changes intended to correct or clarify the tariff (e.g., typos, name and address changes, etc.). To aid the Commission in its review, NorthWestern has provided an index summarizing the proposed revisions. A. Section 7.1, Billing Procedure The billing procedure was revised to specifically allow for payment in immediately available funds rather than specifying that all payments must be made by electronic wire transfer. This provides more flexibility to the customer. In addition, NorthWestern Energy is removing its specific bank account information and will instead provide the requisite information directly to the customer. Removing account information allows NorthWestern Energy to change bank accounts without updating the OATT and protects NorthWestern Energy by not having its account information publicly available. B. Attachment C, Methodology to Assess Available Transfer Capacity NorthWestern Energy s proposed changes to Attachment C revise the language to more closely match the language in NERC s Modeling, Data and Analysis (MOD) reliability standards. For example, the mathematical algorithms in Section (1) were revised to include the definition of each acronym, consistent with MOD-029. The proposed changes also include revisions designed to update the language and provide more clarity. For example, the definition of Total Transfer Capability in Section (3) was revised to match 18 C.F.R. 37.6(b)(1)(vi), and broken hyperlinks were removed or edited. The changes do not substantively change the ATC methodology. The proposed changes are marked in the attached tariff record and outlined in more detail in the attached index. When NorthWestern Energy made its baseline etariff filing, the Process Flow Diagram did not pass through the etariff system. NorthWestern has made this diagram an appendix to Attachment C so that it can be filed as a separate tariff record. Kimberly D. Bose, Secretary January 11, 2016 Page 2

3 C. Attachment K, Transmission Planning Process NorthWestern Energy inadvertently omitted Paragraph Reevaluation of Cost Allocation when it submitted its Second Order No Regional Compliance Filing in Docket No. ER This language is being inserted now to conform NorthWestern Energy s Attachment K to those of the other Northern Tier Transmission Group entities. 3 D. Ministerial Changes NorthWestern Energy proposes several ministerial changes throughout the OATT. These changes are detailed in the attached index. These ministerial changes including updating contact information, updating citations to the Standards of Conduct, and correcting typographical errors and broken hyperlinks. III.
