Norsk Hydro: Power failure at Hydro Årdal

Hydro's aluminium plant in Årdal, Norway suffered a close to four hour power
outage, starting 17:15 CET on January 29. The incident caused no personnel
injuries

Under adverse weather conditions in the region Friday evening, the power supply
for the aluminium plant was out for almost four hours due to a technical fault
and Hydro is still investigating the cause of this.

Production of aluminium has now resumed, and efforts are ongoing to stabilize
the production, which is still unstable.

Hydro is currently evaluating the potential consequences of the power outage. It
is currently too early to estimate when full production will resume and what the
resulting financial effects will be.

Hydro Årdal has an annual production of around 190 000 tonnes primary aluminium,
employs around 500 people, and casts sheet ingots and primary foundry alloys.
