One of Hydro Karmøy’s two aluminium production lines, with an annual capacity of 195,000 tonnes of primary aluminum, suffered a power failure early on Monday. The Karmøy technology pilot is not affected by the situation.

Power at the affected facility was restored at a lower amperage. The affected facility has 288 production cells, of which 45 were subsequently taken out of production to enable stable operations. This represents approximately 10 percent of the total production capacity at the Karmøy plant.   

It is too early to estimate the financial consequences or when the plant will be able to restart the shut-down cells and resume full production. Customer impact is expected to be limited.

The cause of the power failure is not known, and Hydro is investigating the cause of the incident. Hydro will provide updates on the efforts to resume normal production.
