Alliant plans expansion of Whispering Willow wind project in Iowa

Alliant Energy  (NYSE:LNT) said July 27 that its 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 as part of a five-year project will add up to 500 MW of clean energy.

Alliant Energy CEO Patricia Kampling and Gov. Terry Branstad (R) announced the utility will invest approximately $1bn to expand its wind energy operations in the state.

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.

The applications are being filed by Alliant’s Interstate Power and Light (IPL). It has filed an application for advanced ratemaking principles on the expansion of Whispering Willow and other potential locations.

In June, Alliant issued a request for proposals (RFP) for more wind power.

Here are some other key details of the wind expansion plans in Iowa:

•If the advanced ratemaking principles filing is approved, Alliant Energy would expect to reprioritize, and in some cases delay, certain components of its current 2016-2019 construction expenditure plan to incorporate this investment.

•Investment estimate includes allowance for funds used during construction, but excludes transmission.

•Requesting 11.5% return on equity.

•Proposing a renewable energy rider.
