Wind and Energy-Transmission Leasing in Big Stone County, Minnesota

A certificate of need is not a route permit -- and BSSA now has both

It's worth being precise about Minnesota's two-step transmission permitting process, because the county hub's coverage of the Big Stone South-to-Alexandria (BSSA) 345 kV line reflects only the first step. In October 2024, the Minnesota Public Utilities Commission granted a certificate of need -- a finding that the line is needed at all, not where it goes. On June 25, 2026, the PUC took the second, more concrete step: approving the actual Route Permit for the Minnesota portion of the roughly 96-mile line, co-owned by Otter Tail Power Company and the Western Minnesota Municipal Power Agency (represented by its agent, Missouri River Energy Services). That distinction matters directly to a landowner or buyer: a certificate of need is a paper finding, but a route permit means an actual corridor through specific parcels -- including land in Big Stone County -- is now fixed, and the project has moved from planning into active landowner engagement.

What the easement actually requires, and how compensation works

With the route permit secured, right-of-way agents for Otter Tail Power and Missouri River Energy Services are now working directly with landowners along the approved path to negotiate easements and finalize structure locations. The route permit itself authorizes a roughly 1,000-foot-wide review corridor, but the actual easement needed to build, operate, and maintain the line is a fixed 150-foot-wide strip -- the company works with each landowner within that 1,000-foot corridor to place poles and lines as unobtrusively as practical before pinning down the final 150-foot easement. Compensation for that easement is structured as a one-time payment, not a recurring lease payment: the amount is based on market studies reflecting fair market value for the underlying land type (agricultural land is valued differently than commercial land, for instance) along the route, applied to the full value of the land under the 150-foot swath. Separate from the easement payment itself, the companies have publicly committed to restoring property disturbed by construction or compensating landowners directly for damage to crops, fences, or other property.

That one-time-payment structure is a meaningfully different instrument than a wind energy lease like the one behind Big Stone County's operating Valhalla Energy Center project, which -- consistent with how wind leases generally work -- involves recurring payments tied to the turbine's ongoing operation for the life of the project rather than a single upfront sum for a fixed easement strip. If you're evaluating land near either kind of project, don't assume the payment structure of one tells you anything about the other.

The construction timeline is still years out -- but the corridor is not

As of the June 2026 route approval, BSSA construction is targeted to begin in 2028, with the line entering service by the end of 2030. For a buyer, that's a meaningful gap: the corridor and easement negotiations are active now, well ahead of any visible construction, which means a parcel can be under active right-of-way negotiation, or already have a recorded easement, with no physical sign of it on the ground yet. Don't rely on a site visit alone to judge whether a specific Big Stone County parcel is affected -- pull the Big Stone County Recorder's records for any already-recorded easement, and check the project's own landowner-resources materials (BigStoneSouthToAlexandria.com) or contact Otter Tail Power directly for the approved route's current status relative to a specific parcel.

If you're the landowner being approached, or buying land already under an offer

If a right-of-way agent has approached you about an easement for the BSSA line, the county's Wind Power Management Ordinance (adopted 2006) governs wind-turbine siting specifically and doesn't directly regulate transmission-line easements, so county wind setbacks aren't the relevant check here -- the route permit and easement negotiation are state-level (PUC) and company-level processes instead. What is worth checking locally: whether Environmental Services has any record of the approved corridor crossing your specific parcel, and whether any existing agricultural use, drainage tile, or irrigation infrastructure on the property has been discussed in the easement negotiation, since restoration commitments are more useful when they're specific rather than general. If you're buying land that already has a signed easement or is inside the approved corridor, request the actual recorded easement document from the Recorder's Office rather than relying on a listing description -- confirm the easement's width, whether it transfers automatically to a new owner (transmission easements of this kind typically run with the land), and whether any one-time payment was already made to the prior owner or remains outstanding.

For wind-specific leasing -- whether a new offer tied to further Valhalla-area development, or land already under an existing wind lease -- the county's 2006 wind ordinance sets siting and setback minimums that a lease's specific terms cannot undercut, but the lease's payment structure, term length, and what happens if the developer becomes insolvent are matters of contract, not ordinance, and are worth review by an attorney experienced in energy leases before signing anything.
