The roughly 35-mile long line will run from the Rockdale Substation, Dane County,
Wisconsin, to the Paddock Substation, in Rock County, Wisconsin. The Commission
chosen route is estimated to cost about $132,706,200
This is the first transmission line proposed in Wisconsin primarily for economic
reasons. Historically, transmission lines have been proposed and approved based
upon reliability needs to ensure that the transmission grid remains adequately
robust to survive loss of infrastructure that could otherwise cause blackouts. From
its inception, the Paddock-Rockdale proposal was focused on decreasing the congestion
charges associated with bringing power into Wisconsin.
In its approval the PSC required ATC to test for
stray voltage at all dairy operations along the approved route prior to
construction and again after the project is energized. It also
ordered ATC to work with the distribution utility and farm owner to
rectify any stray voltage problems arising from the construction and
operation of the project.
