In February 2022, Albras lost Potline 2 due to a power outage, shutting down 223 pots. After three months, with the support of Hydro’s technical team, 75% of the pots are in operation and production levels are on the rise. The early failure rate is below 5%. Only 6 tap outs (4 in bath phase) and 2 cut outs due to iron contamination. Daily average number of pots above 1000°C is 5.5. Average acidity has been below 4% in the first 5 days. Originally expected to end in early November, the work is now forecast to finish four months in advance, in July, and there have been no safety incidents. The aim of this work is to describe in detail the pathway leading to what has become the most successful restart in the history of Albras in terms of pace, success rate, process consistency, operational stability, and human capital development.
