MADISON, WI (WTAQ) - The state’s largest electric utility is about to own a sizable wind energy farm in southwest Wisconsin.

The state Public Service Commission voted 2 to 1 Thursday to let We Energies buy the Montfort wind farm in Iowa County for $27 million.

Commission chairman Phil Montgomery said the purchase allows We Energies to re-power the 20 turbine wind farm, which started operating 11 years ago. The utility had a contract to buy 25-and-a-half of the 30 mega-watts the wind farm is supposed to generate.

Wisconsin Power and Light is buying the rest.

PSC member Eric Callisto cast the only no vote. He says it force utility customers to pay more for the power that’s generated at Montfort.
