SOO Green High-Voltage electric transmission line to run from Mason City to Chicago approved by Iowa Utilities Board

MASON CITY — The Iowa Utilities Board on Wednesday approved a petition for a franchise to construct, maintain, and operate the new SOO Green High-Voltage Direct Current Link electric transmission line project that runs from the Mason City area to Chicago. 

The project will create an innovative new model for transmission development that will bury a state-of-the-art, 525 kilovolt underground high-voltage direct current transmission line along private rights-of-way of the railroad alignment owned in various forms by the Canadian Pacific Railroad, except for a small section that will be located on public road right-of-way in Clayton County.

SOO Green officials say that would reduce Midwest transmission constraints and deliver renewable energy to customers across the United States with significantly reduced visual and environmental impacts.

The 174 mile transmission line will run through Cerro Gordo, Floyd, Chickasaw, Allamakee, Clayton, Dubuque, Jackson and Winneshiek counties in Iowa before continuing into Illinois.
