Alliant Energy announces another major wind investment

Published 03 August 2017

Alliant Energy's Iowa energy company is pursuing another major wind investment that will help solidify Iowa's national leadership in renewable energy.

"The customers and communities we serve will benefit from this cost effective clean energy," said Doug Kopp, president of Alliant Energy's Iowa energy company. "Our wind projects will help keep energy costs stable over the long-term for customers."

Alliant Energy is seeking approval from the Iowa Utilities Board to add up to 500 megawatts of wind energy in Iowa. A decision is expected in early 2018.

The company received approval in 2016 for a similar expansion. The combined projects would represent a $1.8 billion investment and add up to 1,000 megawatts of new wind generation in Iowa. That's enough to power up to 430,000 Iowa homes a year. As a result, wind is expected to be more than one-third of the company's Iowa energy mix in 2020.

"Iowa has seen tremendous benefits from the expansion of the wind energy industry in our state. We appreciate Alliant Energy continuing to invest in wind and other renewable energy sources to power our state," said Bill Northey, Iowa Secretary of Agriculture.

Alliant Energy's wind expansion projects are expected to create hundreds of construction and other jobs while generating tens of millions of dollars in additional property taxes and payments to landowners.
