Two electric consumer groups have sued Wisconsin regulators alleging they followed the wrong process when they approved a giant wind farm in Minnesota.
The Public Service Commission in July approved Wisconsin Power & Light's plan to build a $497 million wind farm in Freeborn County near Albert Lea, Minn. The farm could cost residential electric customers $9 more a month.
In a lawsuit filed Friday in Madison, Wisconsin Industrial Energy Group and the Citizens Utility Board allege the PSC performed a much less stringent review than state law requires.
PSC officials didn't immediately return a message Friday afternoon. Steve Schultz, a spokesman for WP&L parent company Alliant Energy, says the issue is settled.
