Siemens will supply 448 wind turbines -- its largest onshore order even -- to Billionaire Warren Buffett's MidAmerican Energy in the US.
As previously reported in Renewable Energy Magazine, MidAmerican plans to develop as much as 1.050 MW of additional wind generation in the US state of Iowa.
In November, construction of the $1 billion project got underway in five sites located in Grundy, Madison, Marshall, O’Brien and Webster counties.
The entire project is expected to be completed and generating power by late 2015.
Each of the wind turbines supplied by Siemens has a nominal rating of 2.3 MW and a rotor diameter of 108 meters. In addition to providing the hardware, Siemens will also be responsible for the service and maintenance of the 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 GW in the last fiscal year," said Markus Tacke, CEO of the Wind Power Division of Siemens Energy.
"This new order from MidAmerican Energy once again highlights that we are one of the leading suppliers in the U.S. wind power market," Tacke said.
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.
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.
