Global wind turbine manufacturer Vestas Wind Systems A/S â¿¿ which has three operating factories in Colorado â¿¿ said Wednesday it has landed its largest North American order for wind turbines to date. The 190 V90-3.0 megawatt turbines to be made by the company are destined for four California wind farms at the Alta Wind Energy Center near Tehachapi, Calif. Vestas said all the blades for the Alta order will be made at its Windsor factory north of Denver. A majority of the towers will be made at its Pueblo factory, the company said. Vestasâ¿¿ nacelles factory in Brighton wonâ¿¿t be involved in the Alta order because it manufactures the housing units for 2 megawatt turbines; the Alta order calls for 3 megawatt turbines, Vestas spokeswoman Aili Jokela said via email. The nacelles will be made by Vestas factories in Denmark and Italy, Jokela said. Vestas (CPH: VWS ) is based in Randers, Denmark. Portland, Ore., is its U.S. headquarters. The four wind farms, called the Alta Projects II-V, will be capable of generating up to 570 megawatts of power when completed in 2011. The buyer, Terra-Gen Power LLC, based in New York City, on Wednesday announced it had closed $1.2 billion in financing for the project. â¿¿The entire Vestas team looks forward to helping Terra-Gen bring this exceptional project to reality,â¿ said Martha Wyrsch, president of Vestas Americas, in a statement. Vestas said the Alta contract includes delivery and commissioning as well as a five-year service and maintenance agreement. Delivery is scheduled for late 2010. The first 50 turbines will be commissioned by the end of 2010 and the remaining ones will be online in the first half of 2011. Vestas said the Alta order is its eighth deal announced for the North American market so far this year. To date, the company has announced 1,336 megawatts worth of orders in North America, Vestas said.
