CARMEL, Ind. – The manager of the Midwest electrical grid plans a giant transmission project over several years with 24 lines across 11 states. The project includes a line from south central Wisconsin, through southern Vernon County, across the Mississippi River, to a site northwest of Rochester in Minnesota. The entire project would be the largest regional grid update in U.S. history. The Indiana-based Midcontinent Independent System Operator is readying a campaign for regulatory approval from state agencies. The advocacy group Clean Wisconsin already has weighed in by heralding the project as doubling the clean energy that Wisconsin produces. The project may face opposition from conservationists, as did another trans-Mississippi River powerline that has been built 102 moles from Dubuque in Iowa to Madison in Wisconsin.
