About ATC
ATC describes itself as a Wisconsin-based, federally and state-regulated utility that plans, builds, operates and maintains the regional electric transmission grid. Its high-voltage power lines carry electricity from where it is generated to the local utilities that deliver it to homes and businesses, and its network reaches parts of Wisconsin, Minnesota, Illinois and Michigan's Upper Peninsula. The company is a member of the Midcontinent Independent System Operator (MISO) and works with it on planning interconnections for renewable generation projects across the Upper Midwest.
