Babcock & Brown has ordered 443, 1 MW turbines from Mitsubishi Heavy Industries (MHI) for use in four wind farms in the US. The biggest project, as yet unnamed, is located in Colorado and will use 180 of the turbines, while 135 are destined for the fourth and fifth build outs of the Sweetwater wind development in Texas. A third group of 90 turbines is bound for the Aragonne Mesa project in New Mexico and the last 38 will go to the Buena Vista plant in California. Buena Vista and Aragonne are due to begin operation at the end of this year, while the two larger projects are expected online in 2007. The deal, the largest order ever received by MHI, is worth ´300 billion and brings the total volume of wind turbine orders received by the Japanese company to 1843 MW.
