Wind Energy

Overview

MidAmerican Energy began installing wind turbines in 2004 and is a recognized leader in the use and development of renewable energy. Our wind projects foster economic development while demonstrating the company’s commitment to renewable energy and environmental respect. No other U.S. rate-regulated utility owns more wind-powered generation capacity.

In 2011, MidAmerican Energy added 593.4 megawatts of new wind-powered generation to its existing wind portfolio 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 three projects consist of 258 wind turbines.

In 2012, MidAmerican Energy solidified its No. 1 ranking when it completed a 407-megawatt wind expansion project in Iowa. The 2012 expansion included the 105.6-megawatt Vienna wind project, located in Marshall and Tama counties; 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 consist of 176 wind turbines. In 2012, MidAmerican Energy also was recognized with the Platts Global Energy Green Energy Supplier of the Year Award for its wind expansion projects.

In May 2013, MidAmerican Energy announced plans to invest up to $1.9 billion to expand its wind generation fleet and add up to 1,050 megawatts of wind generation in Iowa by year-end 2015. Construction activity is now underway at each of the five project sites, which are located in five Iowa counties – Grundy, Madison, Marshall, O’Brien and Webster counties. The wind expansion will provide more than $3 million in landowner payments each year and more than $360 million in additional property tax revenues over the next 30 years. The expansion will be constructed at no net cost to the company’s customers and will help stabilize electric rates over the long term. Approximately 1,000 construction jobs will be added to Iowa’s economy during the two-year construction period, and approximately 40 new permanent jobs will be added when the expansion is complete.

Approximately 2,285 megawatts, or nearly 30 percent, of MidAmerican Energy’s total owned generation capacity currently comes from energy generated by the company’s 1,267 wind turbines. Once the expansion is complete, approximately 3,335 megawatts, or approximately 39 percent, of MidAmerican Energy’s total owned generation capacity will come from wind-powered generation from 1,715 wind turbines.
