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.
Fort Knox is unveiling the largest solar panel array on a military installation east of the Mississippi River. The new additions will complement the large solar network already operating at the post.
A ceremony Wednesday morning at the Hardin County army post will debut the array, which will be larger than any other solar panel farm in the state of Kentucky.
The new system includes 10,000 photovoltaic panels, which convert sunlight into electricity. A Fort Knox spokesman says the post will be able to supplant a portion of its energy consumption with the solar panels at a cheaper rate than electricity provided by local power plants.
The new array was constructed at no cost to the government through a partnership with Nolin Rural Electric Cooperative Corporation.
At the conclusion of a 25-year contract, ownership of the array will be transferred to Ft. Knox, with all energy production available to the military post at no cost.
