Wisconsin Power and Light Company issues $4 million in customer credits

Credits will be issued beginning with bills processed on December 10th

Wisconsin Power and Light Company (WPL), a subsidiary of Alliant Energy Corporation (NYSE: LNT), will issue a credit to its electric customers through all billing cycles beginning with bills processed on December 10, 2007. The total credits issued will be approximately $4 million.

The additional refund represents overall savings from June 2007 through October 2007, and is the specific result of lower fuel costs. Virtually all retail electric users should expect to receive the credit that will vary based on their usage billed during December. For a typical residential customer using 600 kilowatt-hours of electricity per month, the credit would be approximately $2.61.

“WPL meets its customer demands through a balanced and diversified energy portfolio that includes a variety of fuel types, including renewable resources, coal, nuclear and natural gas,” said Barbara Swan, President-WPL. “We welcome the reduction in fuel costs and are pleased we can pass these savings on to our customers during the holiday season.”

The WPL refund complies with today’s order by the Public Service Commission of Wisconsin which allowed WPL to refund any over-collection of fuel costs for the period running from June 2007 through December 2007. The agreement was endorsed by several customer groups, including the Citizens Utility Board and the Wisconsin Industrial Energy Group.
