A planned $8 billion investment in building transmission capacity will generate approximately $14 billion in financial benefits for Michiganders over 20 years.

Why Michigan

Need for more transmission

In 2022 and 2024, the Midcontinent Independent System Operator (MISO) approved hundreds of miles of new transmission lines to be built from northern Indiana up through south-central, eastern and central-western Michigan. This $8 billion investment will generate approximately $14 billion in financial benefits for Michiganders over 20 years. 

Siting opportunity

Michigan’s transmission developer will soon begin routing and siting of 345kV and 765kV lines that are part of the 2024 portfolio of projects.  

To minimize the need for development on undisturbed land and streamline the permitting process, state policy makers can consider changing current policy to allow co-location of these projects in highway rights-of-way (ROW) and other existing corridors. 

Challenges

Siting prohibition

The state of Michigan prohibits overhead electric transmission infrastructure in expressway/freeway/interstate highway ROW. (See Michigan Department of Transportation, Utility Accommodation Guidance, Sections V. 6, 11 and 14.) 

Our work

By opening up all public ROW along highways to allow for co-location of high-voltage transmission, Michigan can become a regional and nationwide leader in common-sense transmission siting solutions. Co-location can also foster the development of electric transportation networks as well as modernized communications infrastructure. NextGen Highways is working with stakeholders to advance options for lifting the current prohibition.
