Isn’t this transmission line meant just to serve Madison?
No. Because there is no electric generation in Waunakee, power is delivered to the area by transmission lines from three directions: north, west and south. While energy from the Columbia Power Plant near Portage serves much of the state, Waunakee also is served in part by the Blount Street Power Plant in Madison. In fact, power typically flows north into Waunakee from Madison on the existing 69-kilovolt transmission line, which was built in 1919. Because this and surrounding lines have limited capabilities, Waunakee is in the center of a larger geographic area that is becoming increasingly vulnerable to widespread outages. The scenario in which this could happen is when a line becomes overloaded and/or fails in some way, the electricity automatically takes an alternative path. In the case of this area, no alternate path exists that can accommodate the additional power. This can result in a situation on the transmission network that is similar to blowing circuits in your home. This proj
