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 406.9-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 in five Iowa counties – Grundy, Madison, Marshall, O’Brien and Webster.

Prior to the Wind VIII expansion, approximately 2,285 megawatts, or nearly 30 percent, of MidAmerican Energy’s total owned generation capacity came from 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.
