Iowans will soon see a significant increase in clean, economical wind energy generation from Alliant Energy.

Earlier today, Alliant Energy CEO Patricia Kampling and Gov. Terry Branstad announced the utility will invest approximately $1 billion to expand its wind energy operations in the state.

“Our customers expect low-cost, clean energy, which is exactly what this project will bring to the communities we serve,” said Doug Kopp, president of Alliant Energy’s Iowa utility. “Wind has no fuel costs and zero emissions, making it a win-win for Iowans and the Iowa economy.”

Alliant Energy’s Iowa utility is seeking regulatory approval to expand its Whispering Willow Wind Farm in Franklin County and possibly develop wind energy in other areas of the state. The five-year wind project will add up to 500 megawatts of clean energy to economically meet customer needs. The company is seeking approval now to maximize the value of renewable energy tax credits to benefit its customers.

The new wind project is part of Alliant Energy’s vision for a clean energy future. From 2005 to 2030, Alliant Energy is targeting a 40% reduction in carbon dioxide emissions. In addition, the project will generate tens of millions of dollars in property taxes, and result in more than 1,500 jobs at the height of construction – boosting Iowa’s economy while supporting customers seeking to use more renewable energy.
