This is the largest order for onshore wind turbines for Siemens and the largest single order for onshore wind power awarded globally to date.

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.

The 448 wind turbines of the type SWT-2.3-108 will be equipped at five MidAmerican Energy wind power plants in Iowa. Each wind turbine has power output of 2.3 MW and a rotor diameter of 108 meters. 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.

"Siemens not only leads the way for offshore wind power worldwide, we are also a very successful player in the onshore wind industry. In Europe and Africa alone, we successfully installed more than 1 gigawatt in the last fiscal year. This new order from MidAmerican Energy once again highlights that we are one of the leading suppliers in the U.S. wind power market," said Markus Tacke, CEO of the Wind Power Division of Siemens Energy.

Iowa is one of the leading 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 eco-friendly 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.

Wind power and associated service activities are part of Siemens' Environmental Portfolio. Approximately 43 percent of its total revenue stems from green products and solutions. That makes Siemens one of the world's leading providers of eco-friendly technology.
