Alliant Energy's 200-MW Iowa Wind Facility Begins Commercial Operation

Interstate Power and Light Company (IPL), a subsidiary of Alliant Energy Corporation, said that it has initiated commercial operation of its first owned-and-operated wind farm in Iowa. The Whispering Willow Wind Farm-East in Franklin County, Iowa has a capacity of 200 megawatts (MW).

"This is an important day for our company, electric customers and the environment as we continue to strive to meet the increasing demand for green energy," said Bill Harvey, chairman, president and CEO for Alliant Energy. "We believe the addition of Whispering Willow Wind Farm-East to our renewable energy portfolio moves us further down the path to a greener energy future."

Whispering Willow Wind Farm-East consists of 121 wind turbines spread out over 144 square miles in Franklin County, Iowa. Construction on the wind farm began in the fall of 2008. The Iowa Utilities Board (IUB) approved IPL's request for ratemaking principles pertaining to the construction of up to 200 MW of wind power in February 2008.

The IUB's approval included a return on equity of 11.7 percent and a 25 year depreciation life the IPL wind development. Ratemaking principles are fixed and define how the costs associated with building wind facilities will be recovered in utility rates throughout the life of the project.
