This line and related substation work is part of the Rock River - Elkhorn conversion project, which will convert the existing 69-kilolvot system serving portions of Rock and Walworth counties from 69-kilovolts to 138 kilovolts. The growth in the area has increased the strain on the existing electric transmission system, which was not designed to accommodate the growing electric consumption. This SW Delavan - Bristol project, approved by the Public Service Commission in 2006, connects the a new Alliant-owned substation southwest of Delavan to the Bristol Substation northesat of Delavan. Construction is expected to begin in November 2007. The line will initially operate at 69-kV until 2009 when all of the related work on the system is expected to be completed.  View map (158k pdf)

The new single circuit structures will be weathering steel or galvanized steel. The span lengths (distance between poles) of the structures vary from approximately 300 feet to 700 feet.
