MidAmerican Energy began installing wind turbines in 2004 and is a recognized leader in the use and development of
renewable energy. No other U.S. rate-regulated utility owns more wind-powered generation capacity.
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 2012, MidAmerican Energy solidified its No. 1 ranking when it completed a 407-megawatt wind expansion project in Iowa.
With the 2012 expansion project complete, 2,285 megawatts, or approximately 30 percent of MidAmerican Energy’s total owned
generation capacity, comes from energy generated by the company’s 1,267 owned wind turbines. The wind projects foster
economic development while demonstrating the company’s commitment to renewable energy and environmental respect.
MidAmerican Energy earned a 2012 Platts Global Energy Award, Green Energy Supplier of the Year, for its wind expansion
On May 8, 2013, MidAmerican Energy announced its plans to add up to 1,050 megawatts of wind generation, consisting of up to
656 new wind turbines, in Iowa by year-end 2015. The wind expansion will enhance economic development and provide in excess
of $360 million in additional property tax revenues over the next 30 years. Landowner payments totaling $3.2 million per year
also are expected as a result of the expansion. In addition, the expansion is planned to be built at no net cost to the
company’s customers and will help stabilize electric rates over the long term by providing a rate reduction totaling $10
million per year by 2017, commencing with a $3.3 million reduction in 2015.
If the expansion is approved by the Iowa Utilities Board, MidAmerican Energy will own and operate approximately 3,335
megawatts of wind generation capacity in Iowa by year-end 2015.
