BECI 765 kV:

What Wisconsin Residents Need to Know

A proposed 190-mile, 765-kilovolt transmission line could reshape communities, farmland, ecosystems, and energy decision-making across southern Wisconsin. Residents deserve more than a chance to choose between possible routes—they deserve a transparent, public examination of whether this massive project is necessary, equitable, and truly in Wisconsin’s best interest.

What We Know about the BECI 765kV Transmission Line

Pink lines represent existing transmission lines. Notable locations include Columbia Substation, Sugar Creek Substation, and study segment routes crossing counties such as Dodge, Jefferson, and Waukesha.

Proposed Connections: Bell Center–Columbia–Sugar Creek–Illinois/Wisconsin State Line, or BECI — the name of the proposed project.

Current Stage:

Early study-segment and route-development phase; no final route selected

Midcontinent Grid Solutions (MGS) plans to submit their proposal to the Wisconsin Public Service Commission (PSC) early 2027. They hope to be in-service by June 1, 2034.

MGS says BECI is intended to improve regional reliability, move more power across the Upper Midwest, accommodate load growth, and support future generation interconnection.

Cost - Benefit Analysis

Potential benefits claimed

Public-interest concerns to examine

Support for reliability and resilience

Whether Wisconsin communities bear impacts for benefits that primarily accrue elsewhere

Greater ability to move electricity across the region

The evidence for the specific need, timeline, and size of the proposed line

Ability to connect future generation resources

Whether the line will accelerate genuinely clean, local, and affordable energy—or primarily serve speculative load growth

Potentially more flexibility during outages or extreme weather

Whether lower-impact alternatives could provide comparable reliability benefits

Regional grid capacity for future demand

Whether future demand actually warrants increased grid capacity and if the ratepayers and landowners will be protected.

A new transmission backbone for the Upper Midwest

If the route follows preexisting infrastructure routes and what harms utilizing a new route could potentially cause to farms, homes, habitat, water, and local communities

Wisconsin can support a reliable, affordable, clean electric system without giving utilities and regional planners a blank check. The test is not whether transmission can provide benefits. The test is whether this proposal has demonstrated that it is necessary, fairly financed, transparently planned, and less harmful than realistic alternatives.

What Residents Can do Right Now

Review the study segments

The developer is currently seeking input on broad study segments before it develops preliminary route alternatives. Review the interactive map, identify nearby homes, farms, waterways, habitat, schools, cultural sites, local businesses, and other resources, and document concerns in writing. The current developer comment deadline is September 7, 2026.

Attend a Developer Open House

Midcontinent Grid Solutions is hosting 8 open houses while collecting public comments.

If we can impart one piece of advice, it’s this:

Go.

Show up. Ask questions. Document everything.

Submit your comment to MGS about the proposed routes

This is a developer/project comment—not yet a PSC comment for the official case record.

Be sure to include your

  • City, town, county, or general relationship to the area

  • The specific study segment or nearby landmark affected

  • Concrete local impacts or resources that should be avoided

  • Any route alternatives or constraints you believe must be evaluated

  • Questions you want answered before a route is advanced

  • A request that your concerns be carried forward into the PSC application and environmental review.

And like we said before, DOCUMENT EVERYTHING.

Prepare for the PSC case

When a formal application is filed, the Public Service Commission of Wisconsin will open a docket. That is when public comments can be filed for the record during an announced open comment period. The PSC says it considers these comments in its decision-making process; comments can generally be filed online during an open period or mailed with the docket number clearly included.

A comment to the developer and a comment to the PSC are not the same thing. Submit concerns now so they are documented during route development, and can be pointed to during PSC proceedings — but plan to submit them again through the PSC once the official docket and comment period open.

Know the law

There are many state laws regarding utilities and transmission, here are a few for you to look over. It is always valuable to know the law regarding land use, utilities, and infrastructure buildout.

196.491(3)(d)2.‍ ‍The proposed facility satisfies the reasonable needs of the public for an adequate supply of electric energy.

196.491(3)(d)3. The design and location or route is in the public interest considering alternative sources of supply, alternative locations or routes, individual hardships, engineering, economic, safety, reliability and environmental factors

196.491(3)(d)3m. For a high-voltage transmission line, as defined in s. 30.40 (3r), that is to be located in the lower Wisconsin state riverway, as defined in s. 30.40 (15), the high-voltage transmission line will not impair, to the extent practicable, the scenic beauty or the natural value of the riverway.

196.491(3)(d)3r. For a high-voltage transmission line that is proposed to increase the transmission import capability into this state, existing rights-of-way are used to the extent practicable and the routing and design of the high-voltage transmission line minimizes environmental impacts in a manner that is consistent with achieving reasonable electric rates.

196.491(3)(d)3t. For a high-voltage transmission line that is designed for operation at a nominal voltage of 345 kilovolts or more, the high-voltage transmission line provides usage, service or increased regional reliability benefits to the wholesale and retail customers or members in this state and the benefits of the high-voltage transmission line are reasonable in relation to the cost of the high-voltage transmission line.

196.491(3)(d)4. The proposed facility will not have undue adverse impact on other environmental values such as, but not limited to, ecological balance, public health and welfare, historic sites, geological formations, the aesthetics of land and water and recreational use.

196.491(3)(j) Any person whose substantial rights may be adversely affected or any county, municipality or town having jurisdiction over land affected by a certificate of public convenience and necessity for which an application is filed under par. (a) 1. may petition for judicial review, under ch. 227, of any decision of the commission regarding the certificate.

And most importantly, stay informed and organize locally

  • Sign up for project and PSC docket updates.

  • Connect with groups organizing for residents, ratepayers, and business owners. No765Line is an excellent resource and organization to partner with.

  • Attend open houses, town meetings, and future PSC hearings.

  • Talk with neighbors, farm organizations, local officials, conservation groups, and community organizations.

  • Ask municipal leaders to request complete information about route impacts, emergency planning, agricultural mitigation, environmental review, and public costs.

  • Preserve evidence: photos, maps, drainage information, well locations, farm-operation details, wildlife observations, and written documentation of local concerns.

How to Comment to the PSC

The PSC is the state agency that will evaluate a formal BECI application. At the time of this page’s publication, BECI is still in early route planning and no final route has been selected. When the formal PSC docket opens, residents should submit comments directly to the PSC during its announced public-comment period.

How the PSC process works

  1. The developer files an application with the PSC.

  2. The PSC opens a docket and posts case materials, schedules, notices, and filing information.

  3. The PSC may hold public hearings and establish a public-comment deadline.

  4. Residents can submit a written comment “for the record” online or by mail, following the docket-specific instructions.

  5. The PSC Commissioners ultimately decide whether and under what conditions to approve the project.

The PSC’s case systems allow the public to review docket materials and subscribe for updates. People and organizations with substantial interests affected by a case may also seek formal intervenor status; a granted intervenor can present evidence, question witnesses, and file briefs

A strong PSC comment includes

  • Your connection to the affected community

  • The docket number and project name

  • A clear request—for example, deny, require stronger analysis, select a lower-impact alternative, or impose conditions

  • Specific facts about local conditions and impacts

  • Questions the PSC must answer before approving the project

  • Supporting documents, maps, photographs, expert reports, or local records when available
