The refund represents savings from July 2006 through December 2006, and is the result of lower fuel and purchase power costs. Virtually all retail electric customers should expect to receive the credit that will vary based on their usage during this refund period. For a typical residential customer using 600 kilowatt-hours of electricity per month, the refund would be approximately $2.21, including interest.


“The electricity we generate and purchase to meet our customers’ demand comes from a variety of fuel types including coal, nuclear, renewable resources and natural gas,” said Barbara Swan, President-WPL. “We welcome the drop in fuel costs and are pleased we can pass these savings on to our customers.”


The refund complies with the order by the Public Service Commission of Wisconsin (PSCW), from June 8, 2007, which allowed WPL to refund any over-collection of fuel costs for the time period running from July 2006 through December 2006.
