Mt. Holly, SC
We own a 49.67-perecent interest in the 224,000-tonne Mt. Holly, S.C. plant. Our interest in the facility is held by our wholly owned subsidiary, Berkeley Aluminum, Inc. Alcoa Inc. owns the majority interest in the facility and is the operating partner. The smelter was built in 1980 and is the most recently constructed aluminum reduction facility in the U.S. Our 49.67-percent interest represents approximately 111,000 metric tonnes per year (mtpy) of the facility's annual production capacity.
The smelter contains casting equipment used to cast molten aluminum into standard-grade ingot, extrusion billet and other value-added primary aluminum products. Value-added primary aluminum products are sold at a premium to standard-grade primary aluminum.
The Mt. Holly plant has become an industry leader in production efficiency, energy utilization and environmental control, and proudly holds the title of the first primary aluminum plant in the world to be registered completely to the ISO 9001 Quality System Standard.
The Mt. Holly facility has a tremendous economic impact on the surrounding area, amounting to $835 million annually, according to a 2011 study conducted by the Charleston Metro Chamber of Commerce. Mt. Holly generates $191 million a year in local and statewide spending on goods and services. Statewide, approximately 2,815 jobs have been created as a result of the smelter's presence. Annual payroll is approximately $51 million in the Charleston region alone. 1
