Overview
After more than five years of public involvement and regulatory review, the Public Service Commission of Wisconsin approved a vital addition to Dane County’s electric transmission system in June 2009. This project will serve multiple reliability functions and involves constructing approximately 32 miles of new 345-kilovolt transmission line to connect the existing Rockdale Substation located near the Town of Christiana with the West Middleton Substation. The substations will require some equipment upgrades to support the new line.
| Dane County has experienced in recent years some of the highest growth rates in the state, both in population and electricity usage. The existing transmission system in and around Dane County brings power from outside of the county to meet electric demand. |

However, the system is operating at its limits and additional transmission lines are needed to keep pace with the growing demand, and to strengthen the efficiency and reliability of existing lower voltage lines.
