Large equipment is now in place at the Wacker Polysilicon plant construction site in Charleston, Tenn.
Five structures, each measuring more than 200 feet tall, traveled to the site last year along Interstate-75.
"This is a very visible stride in our progress: the first major milestone of 2013. We are excited to see this equipment now in its permanent place," said Dr. Martin Richtberg, vice president of engineering and head of the construction project.
Last year, there was the final phase of concrete pouring, the arrival of large core equipment, the beginning of steel erection and the start of interior work, added Richtberg.
"It generates great pride to see these incredible structures upright, establishing now the real look of our Charleston plant currently under construction," said Dr. Konrad Bachhuber, vice president and site manager for Wacker Polysilicon North America.
The $1.8 billion plant is slated to start producing polysilicon in mid-2015.
