Minnesota Biennial Transmission Planning
This website provides information for the public and other stakeholders about transmission projects that are being planned in the state of Minnesota. The website was created by the utilities who own or operate transmission lines, substations or other facilities in Minnesota in response to state rules passed in 2003 (see below). You will find information or sources of information here about:
Transmission projects various utilities are planning
Minnesota’s electric transmission system—the high-voltage power lines that transmit electricity from power generation plants to customers—is part of an overall regional transmission grid operated in coordination with other systems throughout the Upper Midwest and Eastern United States.
The system was originally designed to deliver power to major electric load centers such as the Twin Cities metropolitan area, Duluth, Mankato, Rochester and St. Cloud, as well as to interconnect utilities in the state to ensure reliable delivery of electricity. It acts, in many ways, like a regional highway system that provides the physical link between power producers and utilities and delivers electricity to substations and distribution systems that serve farms, businesses and homes. See how the transmission system works.
- How you can participate in the process of the development of transmission projects in Minnesota
- Legislation that requires utilities to coordinate planning efforts and create opportunities for public participation
- Studies of Minnesota’s transmission system
By November 1 of each odd-numbered year, any utility that owns or operates electric transmission lines in Minnesota is required (Minnesota Statutes 216B.2425) to submit a transmission projects report to the Minnesota Public Utilities Commission. The report is called the Biennial Transmission Projects Report, or Biennial Report, and the 16 utilities involved file this report jointly.
Learn about the legislation requiring transmission planning reports and public participation in Chapter 2 of the 2013 Biennial Transmission Project Report and in the Biennial Transmission Filing Rulemaking.
Public meetings and webcast
We encourage all interested stakeholders to learn about transmission projects being planned in the state of Minnesota and participate in the process by providing comments. Our webcasts address the Biennial Transmission Projects Report and how to identify projects that are proposed in each part of the state.
