Executives from several leading turbine manufacturers such as Vestas, Nordex AG and Siemens AG said they are still moving forward with plans to build their own US supply chains.

According to a report filed by freep.com, these companies are establishing a number of US assembly factories  in anticipation of high demand for wind energy in the country in the time to come. For instance, Vestas plans to launch four factories in Colorado this year to assemble blades, towers and nacelles.

“Everybody is hungry to build their supply chain in the region,” reportedly said Kevin Hazel, a Siemens supply-chain management vice president.

Earlier this year, outgoing American Wind Energy Association (AWEA) executive director Randall Swisher had said that wind energy installations are well ahead of the curve for contributing 20 percent of the US electric power supply by 2030 as envisioned by the US Department of Energy. The national trade association said in 2008 the industry had another record growth year - the third record year in a row and generated more than $18 billion in revenues. AWEA shared that the US wind industry reached the 20,000-megawatt installed capacity milestone, doubling installed wind power generating capacity since 2006. By the end of September, the U.S. had over 21,000 megawatts of wind capacity up and running.
