At December 31, 2001, Alliant Energy did not hold an ownership interest in
any companies operating an exempt wholesale generator (EWG).  However, during
2001, Alliant Energy did enter into an agreement to develop an EWG (1,100
megawatt (MW) natural gas combined-cycle generating facility) in western
Michigan.  At December 31, 2001, Resources had made payments and entered into
commitments for the purchase of the long-lead equipment and certain
development activities for this project equal to $238 million.  During 2001,
Alliant Energy also entered into an agreement to guarantee the debt security
of an EWG (6 MW low Btu gas electric generating facility) in Cedar Rapids,
Iowa.  Both of these amounts have been included in the aggregate investment
in EWGs and FUCOs identified in Part III.
