Douglas Kopp

Alliant Energy Corp. announced this morning that Thomas Aller, who has led the Iowa and Minnesota natural gas and electric utility companies for the past nine years as president, will retire from the company effective April 1. Alliant's board of directors has named Douglas Kopp, currently vice president of environmental affairs, to succeed Aller.  Alliant Energy, which has its corporate office in Madison, Wis., operates its utilities from offices in Cedar Rapids and Dubuque.


Aller, who turns 65 next month, has been with Alliant Energy for more than 20 years. He is a member of the Iowa Business Council and has served on the Iowa Transportation Commission and the Iowa Utility Association board.


"It's impossible to calculate the positive impact that Tom has had on Cedar Rapids and the state of Iowa," said Patricia Kampling, Alliant Energy's chairman, president and CEO. Kopp's appointment is part of the company's succession plan, and he has been working with Aller during the past year to ensure a smooth transition, Kampling said.  


Alliant Energy provides regulated electric and natural gas service to approximately 1 million electric and 414,000 natural gas customers in more than 1,300 communities across Iowa, Wisconsin and Minnesota through its two utilities, Interstate Power and Light Co. and Wisconsin Power & Light Co.

Aller's leadership and resilience in restoring service to customers during crippling back-to-back ice storms in 2007 and the floods of 2008 are among some of his most notable achievements, Kampling said. "These are heroic efforts," she said. Additionally, Aller was instrumental in moving Alliant Energy's planned Marshalltown generating station through the regulatory approval process, Kampling said.


Kopp, a Cedar Rapids native, began his career with Alliant Energy in 1992 with Iowa Southern Utilities, which is now an Alliant subsidiary. Prior to starting his current role as vice president of environmental affairs in 2011, he served as a plant manager and in customer service and economic development management positions. He will continue to lead Alliant Energy's environmental initiatives while overseeing the Iowa and Minnesota utilities as president.


"From our perspective, we've got excellent relationships with our customers," Kopp said. "We're going to carry that forward as we look at the future with Alliant Energy."  Much of his focus will be on keeping on top of changing federal and state environmental regulations, he said.


Kopp has a bachelor's degree in industrial administration from Iowa State University; he serves on the board of the Entrepreneurial Development Center and on the United Way of East Central Iowa Financial Solutions Committee. He's expected to transition to Aller's seat on the Iowa Business Council next month.
