PRESS RELEASE:

Commission of Wisconsin (PSCW) has rejected a proposal by Wisconsin Power

Wisconsin, to meet the future energy needs of its customers.

  In a 3-0 oral decision, the PSCW denied WPL's Certificate of Public
Convenience and Necessity (CPCN) application. The PSCW stated that
construction and operation of Nelson Dewey Unit 3 would not be the lowest
cost option for customers. The PSCW also expressed concern regarding Nelson
Dewey 3's potential greenhouse gas emissions and its impact upon the
environment.

  "Our company is extremely disappointed in the PSCW's decision today and
the opportunities lost with it," said Barbara Swan, President-WPL. "We will
need to evaluate the PSCW's decision prior to considering alternatives for
our long-term generation growth strategy in Wisconsin..."

The plant was voted down due to environmental concerns as well as the controversial need for coal power.
