MidAmerican Energy began installing wind turbines in 2004 and is No. 1 in the nation in ownership of wind-powered
capacity among rate-regulated utilities.
In December 2010, MidAmerican Energy announced it would add 593.4 megawatts of new wind-powered generation in Iowa.
The projects included the 443.9-megawatt Rolling Hills wind project, located in Adair, Adams and Cass counties;
the 119.6-megawatt Laurel wind project, located in Marshall County; and the 29.9-megawatt Pomeroy wind expansion
project, located in Pocahontas and Calhoun counties. The final portion of the 593.4-megawatt expansion project was
placed in-service by year-end 2011.
In January 2012, MidAmerican Energy announced it reached an agreement with RPM Access for
the acquisition of the 103.5-megawatt Vienna wind project, which will be located in Marshall and Tama counties.
MidAmerican Energy also announced agreements with Clipper Windpower Development Company for the acquisition of both
the 200.1-megawatt Eclipse wind project, located in Guthrie and Audubon counties, and the 101.2-megawatt Morning Light
wind project, located in Adair County. The three projects, totaling 176 wind turbines, will be complete by year-end 2012.
MidAmerican Energy’s other owned wind projects are located in Buena Vista, Carroll, Crawford, Floyd, Hamilton,
Polk, Pottawattamie, Sac and Wright counties.
When the 2012 wind projects are complete, MidAmerican Energy will own 2,284.8 megawatts of wind generation, with
approximately 29 percent of its total generation capacity powered by wind.
