Should Michigan allow utility companies to build new power lines along public freeway corridors?
On August 26, 2026, the Michigan House passed House Bill 5940 with a 98-0 vote to allow overhead power lines within freeway right-of-ways. This shift aims to accelerate infrastructure expansion for grid operators facing rising power demand.
Why it matters
Co-locating transmission lines along existing highway corridors could significantly lower utility costs and mitigate eminent domain disputes for grid operators. This legislative move addresses the urgent need to expand high-voltage capacity to support AI data centers and broader electrification goals.
The legislation supports the development of projects like the 254-mile mid-Michigan buildout and a 50-mile connector between Eaton and Livingston counties. Building these 345-kilovolt lines underground is 10 to 20 times more expensive than the overhead alternative.
The players
Michigan House of Representatives
The legislative body responsible for advancing the proposed regulatory shift regarding utility infrastructure.
ITC Michigan
A major transmission utility company currently planning multibillion-dollar high-voltage expansions across the state.
The details
Under current law, overhead lines are prohibited within limited-access freeway right-of-ways, forcing utility providers to seek private land easements. The approved bill mandates tighter coordination between the Michigan Department of Transportation and utilities, including a required constructability report for any placement requests. By leveraging existing transport corridors, utilities expect to expedite permitting and construction timelines for necessary high-voltage grid expansions.
Timeline
August 26, 2026: The Michigan House passed House Bill 5940.
Late 2026: ITC Michigan intends to file formal project applications with regulators.
Market Landscape
This move re-evaluates the use of land corridors established by the 1956 national interstate highway system. It follows a trend seen in only 16 other states, which have already moved to permit co-location to resolve transmission bottlenecks.
Business owners should monitor the progress of Senate Bill 933, as passage could shift local land-use patterns and utility construction schedules. Operators involved in infrastructure or large-scale facility development should consult counsel regarding how this potential shift impacts future site-selection costs and permitting risks.
The takeaway
Legislative approval signals a major shift in how grid operators may secure rights-of-way for 345-kilovolt infrastructure. Monitor the filing of formal project applications by major utilities later this year to gauge how quickly these highway-adjacent projects move from approval to active construction.
