High-voltage power line would link Madison, La Crosse

From a blog post by Tom Content in the Milwaukee Journal Sentinel:

American Transmission Co. announced Monday that it will seek to build a 345,000-volt power line linking Madison and La Crosse, with the cost of the project tentatively pegged at $425 million.

The Pewaukee-based power company says two years of study have shown that a 150-mile line would boost electric system reliability, savings for utilities buying power in the Midwest wholesale power market and improve access to wind power generated west of Wisconsin.

No route has yet been selected and the company will spend the next two years exploring routing alternatives in the corridor shown above. A detailed cost estimate will be available once potential routes for the line are selected, said ATC spokeswoman Anne Spaltholz.

The company will host open houses with the public and stakeholders beginning this fall to explore routing choices, she said.

The line, which has been given the name Badger Coulee Transmission Line, is expected to offset the need for about $140 million in lower-voltage upgrades in western Wisconsin communities, ATC said, citing its own studies.

ATC is a transmission-line company that is owned primarily by the local electric utilities in eastern Wisconsin.

Details about the location and cost of the line will be announced when ATC submits a formal application for the line to the state Public Service Commission in 2013. At that time, the company will submit detailed routing information about two alternatives for the commission to consider.

If approved, the line would be built by 2018.
