Transmission Projects Report 2017
Chapter 2: Biennial Report Requirements

2.0 Biennial Report Requirements

2.1 Generally

This is the ninth Biennial Transmission Projects Report to be filed by those utilities that own or operate electric transmission lines in Minnesota.  The obligation to file such a report was created by the Minnesota Legislature in 2001.  Minn. Stat. § 216B.2425.  The statute requires the utilities to file their transmission report by November 1 of each odd-numbered year. 

All eight reports are all available on the Minnesota Public Utilities Commission's eDockets webpage using the Docket Number from the table below.  The past six reports are also available on the webpage maintained by the utilities:  http://www.minnelectrans.com/.  The 2017 Report will also be posted on that webpage.

Minn. Stat. § 216B.2425 requires the utilities to list in the report specific present and reasonably foreseeable future inadequacies in the transmission system in Minnesota.  The term "inadequacy" was not defined by the Legislature or by the Commission.  The utilities have consistently stated that the term "inadequacy" is interpreted to be a situation where the present transmission infrastructure is unable or likely to be unable in the foreseeable future to perform in a consistently reliable fashion and in compliance with regulatory standards.  This definition has been accepted by the Commission and others in past dockets.

The statute spells out certain categories of information that should be included in the report for each inadequacy, and the Commission has adopted rules that expand and clarify what is expected to be in the report (Minn. Rules Chapter 7848).  These laws generally require not only an identification of present and foreseeable inadequacies but also a discussion of alternative ways of addressing each inadequacy and the potential issues and impacts associated with possible solutions to the situation.  The utilities are also required to provide opportunities for public input in the planning and development of solutions to the various inadequacies and to describe in the report what efforts were undertaken to involve the public.  The utilities discuss in Chapter 4 various efforts that have been undertaken to involve the public in transmission planning.

Over the years, in response to experiences with the rule requirements and to other developments in transmission planning, the MPUC has modified the application of the rules in a number of significant ways.  One important modification recognizes that most transmission planning is now done through the Midcontinent Independent Transmission System Operator (MISO).  MISO prepares a report each year, called the MISO Transmission Expansion Plan (MTEP) Report.  MISO transmission planning is conducted in public forums and the MTEP Report is publically available on the Internet.  Unlike this state report, which is prepared every other year and focuses only on Minnesota, the MTEP Report is updated yearly and describes in detail transmission planning needs throughout the entire jurisdictional area of MISO, and not just in Minnesota. 

Consequently, for the past three biennial reports – 2011, 2013 and 2015 – the Minnesota Public Utilities Commission has allowed the utilities to reference the latest MTEP Report to provide information about the identified inadequacies in Minnesota.  The 2017 Report, with the Commission's concurrence, also relies on the latest MTEP Report to identify upcoming transmission needs and to provide the necessary information about the possible alternatives to addressing each inadequacy.  The utilities explain in section 6.1 how to find the pertinent information about each inadequacy in the MTEP Report. 

The MPUC has also recognized that holding public meetings around the state and holding a webinar to describe ongoing transmission planning and needs has not resulted in any substantial participation by the public.  The MPUC has granted the utilities a variance for the past several years from the requirement in the rules to hold yearly planning meetings in each transmission planning zone.  For 2017, the MPUC has continued this variance and exempted the utilities from holding a webinar.  However, the utilities continue to conduct transmission planning in a manner that is open to the public and opportunities are provided for the public to participate in such planning and in the discussion of alternative solutions to the transmission needs under review. 

In its May 27, 2016, Order accepting the 2015 Biennial Report, the Commission said that the MTO shall "file the 2017 Report with content similar to the 2015 Report."  Consequently, the 2017 Report closely tracks the 2015 Report and contains information similar to what was included and accepted in the 2015 Report and in previous reports.

2.2    Reporting Utilities

Minn. Stat. § 216B.2425 applies to those utilities that own or operate electric transmission lines in Minnesota.  The MPUC has defined the term "high voltage transmission line" in its rules governing the Biennial Report to be any line with a capacity of 200 kilovolts or more and any line with a capacity of 100 kilovolts or more and that is either longer than ten miles or that crosses a state line.  Minn. Rule part 7848.0100, subp. 5.  Each of the entities that is filing this report owns and operates a transmission line that meets the MPUC definition.  Information about the utility and transmission lines owned by each utility is provided in Chapter 7 of this Report.  In addition, a contact person for each utility is included in Chapter 7.

The statute allows the entities owning and operating transmission lines to file this report jointly.  The Minnesota Transmission Owners (MTO) has elected each filing year to submit a joint report and does so again with this report.  The utilities jointly filing this report are:

American Transmission Company, LLC
Dairyland Power Cooperative
East River Electric Power Cooperative (will become part of Southwest Power Pool October 1, 2015)
Great River Energy
Hutchinson Utilities Commission
ITC Midwest LLC
L&O Power Cooperative
Marshall Municipal Utilities
Minnesota Power
Minnkota Power Cooperative
Missouri River Energy Services
Northern States Power Company d/b/a Xcel Energy
Otter Tail Power Company
Rochester Public Utilities
Southern Minnesota Municipal Power Agency
Willmar Municipal Utilities

Of the above utilities, East River Electric Power Cooperative, L&O Power Cooperative, Marshall Municipal Utilities, Minnkota Power Cooperative, Rochester Public Utilities and Willmar Municipal Utilities are not members of MISO; all the others are.  Only Minnkota Power Cooperative reports any new transmission projects in this 2017 Biennial Report.  However, since the Mid-Continent Area Power Pool (MAPP) was dissolved in late 2015, resulting in the termination of MAPPCOR, the nonprofit organization that did the planning work for the MAPP utilities, MISO has performed many of the planning roles for Minnkota Power Cooperative.

2.3    Certification Requests

Minn. Stat. § 216B.2425, subd. 2, provides that a utility may elect to seek certification of a particular project identified in the Biennial Report. According to subdivision 3, if the Commission certifies the project, a separate Certificate of Need (CON) under Minn. Stat. § 216B.243 is not required.

On June 1, 2017, the MTO filed a letter to the Commission in the instant docket that there would be no certification requests included with the 2017 Biennial Report.

2.4    General Impacts

In its May 12, 2014, Order approving the 2013 Biennial Report, the Commission recognized that reference to the latest MTEP Report was an appropriate way to provide useful information about the inadequacies identified in the Biennial Report, but that the MTEP Report did not provide general information about the potential environmental, social, and economic impacts of possible alternatives to address the inadequacy, as required by Minn. Stat. § 216B.2425, subd. 2(c)(3).  The Commission stated in its Order at page 6 that "in the future the information [in the MTEP Report] must be supplemented with a fuller discussion of economic, environmental, and social issues related to proposed alternative solutions to inadequacies listed in the report."

The Commission stated in its May 27, 2016, Order approving the 2015 Report that the MTO "shall include in the 2017 Report the requirements addressed in Minn. Stat. § 216B.2425, subd. 2(c)(3)."  Since the Public Utilities Commission and the Department of Commerce staff found that the information the utilities provided in the 2015 Biennial Report satisfied the obligation to report on these impacts, the MTO will address the potential impacts of the various projects in the same manner in this Report.  The discussion below describes how these impacts are addressed.

First of all, it is difficult to provide significant information about a transmission need that is several years in the future.  The MPUC rules require the utilities to identify inadequacies that might affect reliability over the next ten years.  Minn. Rule part 7848.1300, subpart D.  A transmission planner is often not able to identify possible alternatives, let alone the impacts of the alternatives, for projects that are ten years in the future.  Moreover, it is not uncommon for a potential reliability issue that may be looming several years in the future to subsequently be delayed for several more years or even indefinitely because of unforeseen events such as an economic recession or the closing of a large industrial user or even a change in government policy or tax provisions.  Also, more pressing problems may develop that take precedence over more minor concerns and transmission planners may have to focus their attention on other projects. 

Importantly, the statute says that the utilities are to identify general economic, environmental, and social issues associated with each alternative.  This is a recognition that it is not always possible to know during the planning stage what issues may evolve when a particular project is developed in more detail.  It is sufficient to address potential issues in a general way, and that is what the utilities have done here. 

Thus, it is not possible for the utilities to provide specific discussion of potential impacts for each and every Tracking Number that is identified in this Biennial Report.  There are over 100 separate Tracking Numbers, for one thing.  Transmission planners and utility staff are well aware of the kind of issues that arise with any large energy facility, whether a transmission line or a generating plant.  For example, they know that a transmission line may cross a wetland, or run through an agricultural field, or follow a residential street.  They are well versed that a new generating plant has a certain footprint, and may result in the emission of various pollutants, and may require the transport of fuel.  The utilities are aware that a large energy project has tax consequences for local government.  They know that jobs will be created by the construction of a new facility and that the local area will be disrupted for a time while construction is ongoing.  These are the kind of general impacts that can be addressed for projects that have not developed to the point where specific alternatives have been identified. 

The time to provide an in-depth analysis of potential impacts of a proposed project and the identified alternatives is when the utility has determined that a need for new infrastructure is certain enough and imminent enough that a project must be pursued.  This is the time when the public begins to take notice of the need for a project and to participate in the analysis of alternatives.  And this is when the utility must begin to pull together the information that is required to complete applications for a Certificate of Need and for a permit.  These applications, and any environmental review that is conducted as part of the application process, will examine potential economic, environmental, and social issues in depth, with ample opportunities for public involvement and input. 

The MTO can provide in this Biennial Report only a general discussion of the kind of impacts that are associated with certain types of energy projects, like transmission lines and substation upgrades and generating facilities. When a project is far enough along that a specific project has been identified and alternatives considered, a more detailed discussion is possible but that discussion more appropriately belongs in the docket for the permits required for the project.

2.5    Renewable Energy Standards

The utilities are required to include in the Biennial Report a discussion of necessary transmission upgrades required to meet upcoming renewable energy standards.  Minn. Stat. § 216B.2425, subd. 7.  As with previous reports, this discussion is included in Chapter 8.

2.6    Distribution Report/Grid Modernization

In 2015 the Legislature amended Minn. Stat. § 216B.2425   to add two additional requirements for utilities operating under multiyear rate plans—a category that at present includes only Xcel Energy.  Subdivision 2(e) requires Xcel Energy at the time of the Biennial Transmission Projects Report filing to report on its

investments that it considers necessary to modernize the transmission and distribution system by enhancing reliability, improving security against cyber and physical threats, and by increasing energy conservation opportunities by facilitating communication between the utility and its customers through the use of two-way meters, control technologies, energy storage and microgrids, technologies to enable demand response, and other innovative technologies.

This new reporting requirement is often referred to as the Grid Modernization Report.  The PUC in May 2015 opened a separate docket for consideration of efforts related to modernization of the transmission and distribution grid.  Docket Number E999/CI-15-556. 

Further, subdivision 8, which was also added in 2015, provides:

Each entity subject to this section that is operating under a multiyear rate plan approved under section 216B.16, subdivision 19, shall conduct a distribution study to identify interconnection points on its distribution system for small-scale distributed generation resources and shall identify necessary distribution upgrades to support the continued development of distributed generation resources, and shall include the study in its report required under subdivision 2.

On October 30, 2015, Xcel Energy filed its 2015 Biennial Distribution-Grid Modernization Report under Minn. Stat. § 216B.2425.  The PUC assigned a separate docket number to the Report.  Docket Number E002/M-15-962.  On June 28, 2016, in that docket, the PUC accepted the Grid Modernization part of the Report and directed Xcel Energy to file a separate Distribution System Study by December 1, 2016, which Xcel Energy did.

As mentioned above, these reporting requirements apply only to utilities operating under an approved multiyear rate plan approved by the MPUC under section 216B.16, subd. 1, and Xcel Energy is the only utility currently operating under such a plan and the only utility required to file a distribution study and grid modernization plan. Accordingly, Xcel Energy has submitted its Grid Modernization Report and its Hosting Capacity/Distribution Study Report under separate cover for PUC consideration in two separate dockets.
