Alliant Energy has announced the utility will invest approximately US$ 1 billion to expand its wind energy operations in Iowa, USA.
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 project will add up to 500MW. The company is seeking approval now to maximise the value of renewable energy tax credits to benefit its customers.
