Dodge County Reliability Project is complete

Newly energized electric transmission line boosts reliability in Dodge County
Transmission line completed on schedule and within budget

MADISON, Wis. – American Transmission Co. placed in service last week a new 138-kilovolt electric transmission line connecting a new substation located east of Horicon to an existing substation south of Neosho.

Construction on the 13.5 mile line began last fall and continued throughout the winter months despite near record amounts of snowfall. “Although Mother Nature tried to hinder our work, the crews prevailed in getting this project done on time,” said John Garvin, ATC local relations. “The completion of this project is good news for homeowners, businesses and industries in the area that depend on a reliable electric system.”

Central Dodge County communities including Beaver Dam, Hustisford and Horicon have experienced significant growth in recent years. “Electric usage had outgrown the previous system,” explained Garvin. “This transmission line will boost reliability and prevent system problems that could have triggered service interruptions and low voltage conditions.”
