Wind components for this order will be manufactured in Vestas’ facility in Colorado, while the required blades for the Alta project will be produced at its blades factory in Windsor, Colorado. Vestas’ new tower factory in Pueblo, Colorado, will manufacture a majority of the towers.

As per the agreement, Vestas will deliver and commission the wind turbines, as well as it will provide service and maintenance for five years. 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.

Martha Wyrsch, president of Vestas Americas, said: “When completed, it will be the largest wind farm we will have supplied turbines to in our 31-year history as well as the biggest in California.”

Jim Pagano, CEO of Terra-Gen, said: “The project represents an important expansion to the renewable generating base of California and helps us advance our nation’s goals of achieving energy independence in an environmentally responsible manner.”
