LCG, December 18, 2013--Siemens Energy confirmed on Monday that the 1,050-MW wind turbine order it received from MidAmerican Energy Company is the largest onshore wind turbine order in the world. MidAmerican Energy's order consists of 448 Siemens wind turbines for five project sites, with a combined electric generating capacity of 1,050 MW of additional wind generation in Iowa by the end of 2015. Construction activity is underway at each of the project sites.
