Another power company has signed on to purchase power from Wisconsin's largest proposed wind farm in Dodge and Fond Du Lac Counties.

The electricity would be generated by wind farms like the one in Lee County near Mendota.

Alliant Energy has signed a 20-year contract to purchase remaining power available from Invenergy Wind LLC. They want to build a $250 million turbine farm called "Forward Wind Energy Center."

Alliant Energy serves thousands of customers in the stateline.
