Siemens has secured an order from MidAmerican Energy to supply 448 onshore wind turbines that is claimed to be the world’s largest onshore wind power order to date.
The wind turbines, each with a nominal rating of 2.3MW and a rotor diameter of 108m, will be installed in five under-construction projects in Iowa, the US.
Under the contract, Siemens will also be responsible for providing service and maintenance of the wind turbines totalling around 1,050MW, will generate enough electricity to power around 317,000 average Iowa households.
Siemens will assemble nacelles and hubs for the wind turbines at its plant in Hutchinson, Kansas, while rotor blades will be produced at the Fort Madison plant in Iowa.
To be operational by 2015, the five MidAmerican Energy projects are 500MW Highland wind project in O’Brien County; 250MW Lundgren wind project in Webster County; 138.6MW Wellsburg wind project in Grundy County; 117MW Macksburg wind project in Madison County; and 44MW Vienna II wind project expansion in Marshall County,
Siemens Energy wind power division CEO Markus Tacke said the new order from MidAmerican will once again highlight the company as the leading suppliers in the US wind power market.

Siemens awarded largest onshore wind power order to date
Siemens to supply 448 wind turbines with a total capacity of 1,050 megawatts and provide service for several years
The customer, MidAmerican Energy, will equip five wind power projects in the U.S. state of Iowa with Siemens wind turbines
Clean energy for nearly 320,000 American households
Siemens has received an order from the U.S. energy company MidAmerican Energy for the supply of 448 wind turbines. With a total capacity of 1,050 megawatts (MW), this represents not only the largest order for onshore wind turbines for Siemens, but also 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.
"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. Around 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.
