CEDAR RAPIDS, IA – April 24, 2009 – Alliant Energy Corp. (NYSE: LNT) hosted the 3rd annual Supplier Diversity Symposium in Dubuque, Iowa today. The event provided minority and women business owners the opportunity to network with purchasing professionals, learn about supplier diversity efforts in the Midwest, and gain insight into the issues affecting Alliant Energy’s current business and regulatory environment.

Alliant Energy implemented the Supplier Diversity Symposium to encourage diverse suppliers to compete for Alliant Energy’s business. The company spent more than $100 million in 2007 and 2008 with minority and woman-owned businesses. The company anticipates spending over $60 million with diverse vendors this year and is looking to further increase the diverse vendor base.

“Our Supplier Diversity initiative has been successful because we’ve built solid partnerships with our minority- and women-owned businesses,” said Tom Aller, President-Interstate Power and Light (IPL). “We believe our partnerships are based on mutual respect and an understanding of needs. We feel the company benefits from the creativity and new perspectives diverse suppliers have to offer.”

More than 215 minority and women business owners from Iowa, Minnesota and Wisconsin attended the free event held at the Grand River Center in Dubuque. Attendees heard comments from Alliant Energy’s Bill Harvey-Chairman, President & CEO, Tom Aller-Senior Vice President, Resource Development & President, IPL, Dave Jost-Director of Sourcing and Supply Chain, Vanessa Perdomo-Manager of Supplier Diversity and Dr. Floyd Rose-President, Wisconsin Supplier Development Council.
