Century Aluminum Grundartangi Smelter Experiences Temporary Outage; Smelter Operations Resumed

Century Aluminum Company

announced that the Grundartangi smelter, owned and operated by its wholly owned subsidiary, Nordural Grundartangi ehf, experienced a temporary power outage yesterday. The outage resulted from damage sustained, due to abnormal and extreme weather conditions, at an offsite electrical substation owned and operated by the national power grid operator. The outage lasted approximately three hours and power was fully restored after approximately 12 hours. Plant personnel handled the interruption safely and no injuries have been recorded. The smelter is in the process of resuming full operations. Nordural is continuing to evaluate the full impact of the outage on the smelter, which it does not currently believe to be material.
