Alliant Energy Purchases 300-MW Wind Farm Project from Apex

LCG, October 5, 2017--Apex Clean Energy (Apex) Friday announced the sale of the Upland Prairie Wind Farm to Interstate Power and Light (IPL), a subsidiary of Alliant Energy Corporation. Construction is scheduled to commence next spring.

The Upland Prairie Wind Farm will have an electric generating capacity of 300 MW and will include 121 wind turbines, which will be installed on a 30,000 acre site in Clay and Dickinson counties in northwest Iowa. Apex will complete the development work, and then Alliant will proceed with the construction and subsequent operations.

The president of IPL stated, "We are bringing more clean and cost-competitive wind energy to our customers. If our second wind expansion project is approved, one third of our energy in Iowa will be from wind, starting in 2020."

Alliant Energy received approval in 2016 to add up to 500 MW of wind energy, and the company requested a similar expansion from the Iowa Utilities Board (IUB) again in 2017. Alliant estimates the combined projects would represent a $1.8 billion investment and add up to 1,000 MW of new wind generation in Iowa.
