Frequently Asked Questions

What is the timeline for this project?

The project kicked off in early 2023, and a series of open houses were held in April 2023, October 2023, and February 2024. A fourth and final round of open houses will be held June 24 - 27, 2024 before we file our route permit application with the Minnesota Public Utilities Commission (MN PUC). Learn more about our upcoming events.

Following our February 2024 open houses, easement acquisition will begin in South Dakota. On April 15, 2024, we submitted a Facility Permit with the Public Utilities Commission (SD PUC), who will review the application and hold a public hearing before making a decision, which we expect to occur by mid-2025.

A Certificate of Need application was submitted to the MN PUC in September 2023. The MN PUC will hold public meetings in June 2024 before deciding on the application. In Q4 of 2024, a route permit application will be submitted to the MN PUC, who will review the application and hold public meetings and hearings before making a decision, which we expect to occur between mid to late 2026. Following this, easement acquisition will begin in Minnesota.

After all easements have been acquired, construction will occur. The new line is tentatively scheduled to be complete in either 2030 or 2031.

Why is this project needed and what are the benefits?

BSSA is one of 18 new transmission projects in the Upper Midwest identified by the Midcontinent Independent System Operator (MISO) in Tranche 1 of their Long-Range Transmission Planning effort. This project will help ensure electric reliability, increase resiliency to extreme weather events, reduce transmission congestion, and increase access to low-cost energy in the region.

What will the transmission line structures look like?

The typical structure will be approximately 150-foot-high, single-pole, self-weathering steel with double- circuit capability, meaning it can support a second set of conductors. While this is the proposed design, the structure type may vary due to a variety of reasons. We'll continue to share more details as they become available.

Is this transmission line being constructed for wind farms?

The transmission line is being constructed to increase overall reliability of the grid not only in South Dakota and Minnesota, but across the Upper Midwest. This transmission line is not being built because of one specific energy project, but it's possible that future energy generation resources, including wind, may connect to this line in the future. If this occurs, the entities responsible would be subject to a separate MN PUC permitting process as well as the MISO Generation interconnection process.

Will you impact sensitive species (birds, plants, wetlands)?

Otter Tail Power Company and Missouri River Energy Services will undergo a consultation process with federal and state agencies to protect sensitive species within the right of way.

What will happen if I own property on the proposed route(s)?

If your property is located within the study area, you will receive communications about the project by mail and you will be invited to public open house meetings. If your property is located along the final route that is approved by the MN PUC through the regulatory process, a right-of-way agent will reach out to begin the acquisition process. Following this, a right-of-way agent will present an easement based on the fair market value. We'll work with landowners to resolve any questions or concerns to reach an agreement.

What is Right of Way?

Right of way is a portion of land needed for the construction, operation, and maintenance of the transmission line. Typically, a width of 150 feet is needed for a 345-kV transmission line. Right of way is typically secured through negotiation and acquisition of an easement agreement.

What is Right of Entry?

To assess potential routes and conduct the necessary environmental, engineering, and geologic studies/surveys, right of way agents will work with landowners and residents to acquire a temporary right-of-entry agreement. This agreement does not give permission for construction.

What is an Easement?

An easement is the legal document that allows Otter Tail Power Company and Missouri River Energy Services to construct, operate, and maintain transmission structures and lines on your property. A 150-foot-wide easement will be necessary to construct, operate, and maintain the proposed 345-kV transmission line.

How will my input be considered during the routing process?

We value landowner and resident input and will take all feedback and input to the project team for evaluation. Examples of this may include soil type or condition, known cultural areas, quarries, cemeteries, private airstrips, homestead locations, or other critical siting criteria.

How can I get involved?

The best way to get involved in this process is to attend public open houses and public hearings, visit our website, and sign up for email updates. You can also email connect@BigStoneSouthtoAlexandria.com or call (800) 598-5587 with questions, comments, or concerns. Landowners and residents within the route corridors will receive information throughout project development.
