Alliant Energy Corp will be the first company to develop a major wind farm using Clipper Windpower's new 2.5MW wind turbines.
Alliant has contracted with Clipper Windpower for 60 turbines to be installed at a 150MW wind project near Spirit Lake, Iowa. Completion is scheduled for 2006, with the power to be sold to Alliant Energy subsidiary Interstate Power and Light.
Dubbed the Endeavor Wind Farm, the project will be near Clipper Windpower's Cedar Rapids, Iowa, manufacturing facility, which is producing the new 2.5MW Liberty wind turbines. Clipper Windpower expects to produce 30 turbines at the plant by the end of the year and another 150 Liberty turbines by the end of 2006.
The Endeavor Wind Farm is near the 44MW Flying Cloud Wind Farm, developed by Clipper before being bought and completed by PPM using GE turbines. It is operated by GE Energy for PPM, which sells all the power produced to Alliant Energy.
"If we are to be serious about wind being a significant part of our portfolio, then we want to be as cost-effective and reliable as possible," says Alliant's Kim Zuhlke. Alliant Energy, headquartered in Madison, Wisconsin, serves nearly one million electricity customers in the Midwest and has almost 350MW in wind power in its portfolio.
