The outage was a result of extreme weather conditions which damaged an offsite electrical substation owned and operated by the national power grid operator.

The outage lasted three hours and power was fully restored after approximately 12 hours. Plant personnel handled the interruption safely and no injuries were 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 believe to be material.
