American Transmission Co.

American Transmission Co. was founded in 2001 as the first multi-state, transmission-only utility in the United States. Unlike most other utilities, we have a single focus: transmission. Our transmission system allows energy producers to transport electric power from where it’s generated to where it’s needed. It’s similar to the interstate highway system, with high-voltage electricity traveling on the transmission system wires like vehicles on the highway.

ATC provides electric transmission service in an area from the Upper Peninsula of Michigan, throughout the eastern half of Wisconsin and into portions of Illinois. Our nearly 10,000 miles of high-voltage transmission lines and more than 550 substations provide communities with access to local and regional energy sources.

At ATC, we care about the communities we serve. We are proud to help keep the lights on for the greater Madison area, and our offices in Madison and neighboring Cottage Grove allow us to connect with those communities. The Madison Region is a hub for innovation and technological advancement, and we are pleased to be a part of it.
