Wisconsin Power Line Project Approved

LCG, Nov. 24, 2003--An area of northern Wisconsin that has been associated with transmission congestion for at least three years has been approved for an $8.2 million transmission project to be built by American Transmission Co.

The 115-kilovolt line will connect Tomahawk and Rhinelander, following the go-ahead from the state's Public Service Commission. American Transmission Co., which was created three years ago, is the operator of transmission lines in both eastern Wisconsin and some of Michigan's Upper Pensinsula.

The congestion on the transmission path to Rhinelander was serious enough this past summer that diesel generators were connected by ATC and Wisconsin Public Service Corp. in order to prevent supply shortfalls. Actual construction of the line should start next fall, with operation planned to begin around June 2005.
