American Transmission Company (ATC)PO Box 47, Waukesha, Wisconsin, United States

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.
