Power Outage Impacts Alcoa Tennessee Operations.

PITTSBURGH -- Alcoa (NYSE:AA) today announced that the severe electrical storms that hit the southeastern United States this past weekend resulted in a power outage at the company's Tennessee Operations aluminum smelter.

A power substation serving the smelting operations was directly hit by a lightning strike, resulting in a complete power outage at the plant. There were no injuries. Plant employees were able to restore full power to the plant quickly and safely, but one of the two potlines at the plant, representing approximately 107,000 metric tons per year, was not able to be re-started and is currently not operating.

A full re-start plan, timeline for the potline re-start and financial impact is being developed along with an evaluation of impacts on the adjacent can sheet rolling mill which utilizes aluminum from the smelter. However, it is expected that the potline may take several months to re-start.
