Wisconsin farmer fights $900m power line that could cross 120 acres of farm

The MariBell Transmission Project is a proposed electricity corridor across western Wisconsin and into Minnesota. Dairyland Power Cooperative and GridLiance Heartland are developing it to replace an existing 161-kilovolt transmission line. The project matters because it could reshape farms, rural landscapes and the regional power network.

The roughly 140-mile route would connect Marion, Minnesota, with Bell Center, Wisconsin. Its double-circuit system would carry electricity at 765 and 161 kilovolts. Steel transmission structures would stand about 150 to 200 feet tall, with a right-of-way potentially reaching 250 feet wide.

Developers say the project would strengthen grid reliability, improve access to energy resources and meet future electricity demand. Residents and farmers worry about lost farmland, property values, noise, electromagnetic fields and changes to the Driftless region. The developers expected to seek state approval in the fourth quarter of 2026.

MariBell would cover roughly 140 miles between Marion, Minnesota, and Bell Center, Wisconsin. Its structures are expected to reach 150 to 200 feet high. The right-of-way could extend as wide as 250 feet, creating a substantial physical footprint through rural areas.

The Woodhouse family's 2,500-acre cattle operation provides a clear example. One proposed route could pass within 300 feet of the family's home. Another could cut through 120 acres of its cropland and pasture. Both routes would also directly affect the farm of Larry Pedretti, according to the coalition's complaint.

The wider impact could be larger than those farms. The Wisconsin Farm Bureau Federation's preliminary analysis indicated that more than 3,000 member landowners could be directly affected by MariBell and a separate BECI project. That figure covers both developments, not MariBell alone. The final footprint depends on route decisions and state review.

Approval could change how the Woodhouse family lives and runs its fourth-generation cattle operation. The project might place large transmission structures near the home or divide cropland and pasture. That matters because the family works a 2,500-acre farm built across generations.

The coalition's amended complaint says one route would pass within 300 feet of the Woodhouse home. Another could cross 120 acres of the family's cropland and pasture. The complaint also identifies Larry Pedretti's farm as affected by both proposed routes. Plaintiffs allege possible interference with agriculture, property-value damage, noise and electromagnetic-field concerns.

These claims remain allegations, not court findings. If a route is approved, the final design, right-of-way and construction rules would determine the practical effects. Other landowners could also face landscape changes or lost usable farmland. The dispute is therefore about both individual property impacts and broader changes to rural communities.

Dairyland Power Cooperative and GridLiance Heartland present MariBell as part of a wider effort to modernise the Upper Midwest electricity network. Their central argument is that stronger transmission can make the grid more reliable. They also say the project would improve access to energy resources and prepare the system for future electricity demand.

The proposed system would replace an existing 161-kilovolt transmission line with a double-circuit system carrying electricity at 765 and 161 kilovolts. Higher-capacity infrastructure would create a larger regional transmission pathway. The developers plan to use existing transmission corridors where possible, which they say could limit the project's footprint.

Residents question whether those regional benefits justify disruption to farms and communities. Some say the line may serve broader needs without directly connecting nearby communities. Dairyland Power has also said the project is not specifically designated to supply data centres. The need and benefits will be examined during the Wisconsin commission's review.

The Public Service Commission of Wisconsin will decide whether MariBell can proceed through its Certificate of Public Convenience and Necessity process. The developers anticipated filing their application in the fourth quarter of 2026. That makes the commission the key formal decision-maker after the current legal and public dispute.

The review must consider whether the project is needed, how much it will cost, its environmental effects and the routes proposed. Route choices are especially important because one option could pass near a home, while another could cross farmland. The process also includes opportunities for public participation.

Before that application, the Coalition Against MariBell 765 is challenging the project in court. It filed an initial lawsuit in May 2026 and amended it in September to add Timothy J. Woodhouse and Larry Pedretti. A commission decision would therefore follow both legal arguments and public comments, rather than being based only on the developers' proposal.

The main alternatives described are different route options for the MariBell line. Developers say they plan to use existing transmission corridors where possible. That approach is intended to limit the project's footprint and reduce the need for entirely new corridors through rural land.

The route choices create different impacts. One proposed route would pass within 300 feet of the Woodhouse family's home. Another could cut through 120 acres of its cropland and pasture. Both proposed routes are identified as affecting Larry Pedretti's farm. The examples show how changing a route can shift disruption from homes to farmland, or the reverse.

The article does not identify a preferred final route, underground construction plan or alternative energy project. The Public Service Commission's review will consider the proposed routes, along with need, costs and environmental effects. Public participation will give residents and officials an opportunity to argue for less disruptive choices before a decision.

The article describes MariBell's voltage levels but does not explain how transmission works. In standard power-grid practice, electricity is stepped up to very high voltage before traveling long distances. Near users, substations step it down to lower voltages for local distribution and safe use.

For a given amount of power, higher voltage means lower current. Lower current reduces resistive heating in transmission wires, so less energy is lost during a long journey. MariBell would use a double-circuit system carrying electricity at 765 and 161 kilovolts. The proposed structures would support those high-voltage lines across the corridor.

This approach helps move large amounts of electricity across a wider regional grid efficiently. Developers say MariBell would strengthen reliability, improve access to energy resources and meet future demand. The trade-off is a large physical corridor, with structures 150 to 200 feet tall and a right-of-way potentially 250 feet wide.
