Siemens won an order from MidAmerican Energy for the supply of 448 wind turbines. With a total capacity of 1,050 MW, this represents Siemens' largest onshore wind turbine order in company history.
The wind turbines, each with a nominal rating of 2.3 MW and a rotor diameter of 108 meters, are to be installed in five different projects in Iowa. Siemens will also be responsible for service and maintenance of the wind turbines.
Iowa is one of the top U.S. states in wind energy generation. In 2012, around 24 percent of total power generation in the state was provided by wind power. Siemens has already installed 1.2 GW of wind power capacity for MidAmerican Energy to date. Including this new order, these wind projects will provide around 660,000 American households with renewable power when they are completed in 2015.
The nacelles and hubs for the wind turbines of this major order will be assembled at the Siemens plant in Hutchinson, Kansas, and the rotor blades will be produced by Siemens in Fort Madison, Iowa.
