American Transmission Co. projects

Project website for a Wisconsin-based company that owns and operates the high-voltage electric transmission system that powers communities in portions of the Upper Midwest.

Electricity demand in Door County has been growing at an aggressive rate. The 69-kilovolt transmission system serving the northern portion of Door County is quickly reaching its capacity. In addition, most of the northern portion of the county, being served by a single line, is vulnerable to extended interruption of service if that single line suffered an extended outage. Without reinforcements, this system will be susceptible to facility overloads and unacceptably low voltages. Improvements to the transmission system will provide significant voltage support and provide additional transformation capacity to the northern Door County area.
