PowerOn Midwest Tomorrow's reliability starts today.

The project team started by using data from publicly available sources and federal, state, and local agencies. We developed the project study area and held open houses in November 2025.

The next step in the route development process is to identify a route corridor where a possible route could be located and preliminary route options are identified. PowerOn Midwest held the first round of routing open houses in June 2026. Over 1,300 people attended the open houses and we received more than a thousand comments.

The route corridors and preliminary route options were further narrowed based on public input and additional analysis. Using additional public input, we’ll develop a proposed route to submit in Route Permit applications submitted to the Minnesota Public Utilities Commission (MPUC).

Finally, the project team will use all of the information and public input we have gathered throughout the route development process to develop a proposed route that we will submit in our Route Permit application to the MPUC in early 2027.

The MPUC will review the proposed route, along with the other route alternatives brought forward by the public and other stakeholders during the regulatory process, to determine the final routes for the transmission lines.

The CON identifies the issues the proposed project is designed to solve (the need for the project) and reviews how the project benefits the state and region. The application must include the type of infrastructure proposed, size, general engineering information, estimated costs, system alternatives that were evaluated, and other state required information. PowerOn Midwest submitted a CON application to the MPUC on February 3, 2026.

• Application filing and completeness review
• Intervention opportunity
• Environmental Report scoping public meetings
• Scoping decision
• Environmental Report
• MPUC public hearings for the CON
• MPUC CON decision

Step 1: Application filing and completeness review

The MPUC reviews the application for completeness and invites public comment. Once deemed complete, the case is typically assigned to an independent Administrative Law Judge, who presides over the review process.

The Commission determined the Certificate of Need Application was complete on April 6, 2026.

Step 2: Intervention opportunity

Anyone can attend meetings and submit comments without formally intervening, i.e. becoming a "party" to the proceeding. Persons who want to become a party must submit a request to the Administrative Law Judge. Parties may present formal arguments, testimony, and cross examine witnesses - often with legal representation (although not required for individuals). Formal intervention is not required to submit comments on the application.

Step 3: Environmental Report scoping public meetings

The MPUC prepares an Environmental Report (ER) to evaluate human and environmental impacts related to a project. Public meetings were held April 21-30, 2026 to explain the process and gather comments on issues and alternatives that should be addressed in the Environmental Report. The comment period for the Environmental Report scoping meetings closed on May 20, 2026.

Step 4: Scoping decision

Before the MPUC prepares the Environmental Report, it reviews all public input and publishes its Scoping Decision, which outlines the issues to be addressed in the Environmental Report.

Step 5: Environmental Report (ER)

The MPUC gathers information, then prepares and publishes the ER, which must be done before public hearings can take place.

Step 6: MPUC public hearings for the CON

The MPUC holds public hearings presided by an Administrative Law Judge. Notice is published in local newspapers and mailed to landowners and local governments prior to the start of the hearings. Anyone can present comments and express opinions concerning the utilities' proposal or alternatives and the ER. The Administrative Law Judge provides a report that summarizes the hearing record, including public comments, and makes recommendations to the MPUC.

Step 7: MPUC CON Decision

The MPUC makes the final decision about whether to issue a Certificate of Need. In making its decision, the MPUC considers all information in the record and deliberates at a formal MPUC meeting.

A Route Permit is also required from the MPUC prior to building a high-voltage transmission line. A Route Permit application identifies where a transmission line will be located. The Route Permit application also discusses both constraints and opportunities for the new infrastructure that minimizes the overall impact of the project.

• Application filing and completeness review
• MPUC Environmental Impact Statement (EIS) scoping public meetings
• Draft EIS
• MPUC public hearings
• Final EIS
• MPUC Route Permit decision

Step 1: Application filing and completeness review

After a utility files a Route Permit application and it is accepted as complete, the regulatory review process begins.

Step 2: MPUC Environmental Impact Statement (EIS) scoping public meetings

For this project, the MPUC will develop an EIS to identify the potential impacts the transmission line may have in the area where it has been proposed. An EIS typically analyzes, among other things, potential impacts on land use, including agricultural operations, residences, water resources, and other natural resources.

The MPUC will hold public meetings to present information about the project, answer questions from the public, and take comments on the issues that the EIS should address.

In Minnesota, the public may suggest alternate routes for the MPUC to consider in its review and those routes may be considered alongside the route proposed by the utilities. The route options must be specific, including starting and ending points, and may vary in length from a minor shift to many miles. The MPUC will provide information on how to suggest alternate routes and will determine which alternatives should be studied in the EIS.

The MPUC then publishes a scoping decision outlining what the EIS will address and what route alternatives will be included in their review.

Step 3: Draft EIS

The Draft EIS will be made available for review and comment by all stakeholders and the general public.

Step 4: MPUC public hearings

Once the Draft EIS is published, the Administrative Law Judge conducts public hearings, which are designed to receive comments on the routes under review, and how potential impacts of the project could be addressed. The Administrative Law Judge prepares a report summarizing the hearings and makes routing and condition recommendations to the MPUC.

Step 5: Final EIS

The MPUC issues a Final EIS.

Step 6: MPUC Route Permit decision

The MPUC makes its final Route Permit decision at one of its formal meetings after reviewing all materials. A permit can only be issued after a CON is granted. The Route Permit is the only approval required to determine the route of the the transmission line. If the Route Permit is approved, utilities will work to obtain other required permits based on that route - like DNR stream crossing approvals.
