Hemlock Semiconductor Group is permanently closing its idled polysilicon plant in Clarksville, citing global trade disputes that have led to an oversupply of the compound used in solar energy panels.
The company says 50 Clarksville-based employees will be offered to stay with the company, but will have to relocate.
The company's president, Denise Beachy, announced the decision to the The Leaf-Chronicle on Wednesday.
Construction on the on the plant located near the Kentucky line was begun in 2009, and the facility was close to complete when Hemlock announced in 2013 it would not begin construction because of the supply glut and disputes with China over tariffs.
Hemlock will now work with local officials to decide how to dismantle the facility and to determine which parts can be repurposed for other business uses.
