The company would be building upon its energy efficiency measures, when its proposed expansion at the Nelson Dewey generating station becomes operable in 2013.

The proposed changes to Wisconsin Power and Light Company’s (WPL) generation fleet will be filed with the Public Service Commission of Wisconsin (PSCW) as part of WPL’s testimony filing related to the proposed expansion of the Nelson Dewey generating station, in Cassville, Wisconsin, and are subject to the approval of the PSCW.

Barbara Swan, president of WPL, said: Alliant Energy is committed to reducing greenhouse gas emissions, in Wisconsin and throughout our service territory. We believe our proposal addresses the critical balance of meeting important environmental objectives with the equally important goal of providing reliable and affordable power to our customers.
