Capacity and output of the group companies’ plants
Full capacity of the group companies’ plants – the sum of the capacity of operating plants, irrespective of the group’s share in the plant.
| Metal | Stage | Full capacity / Output | Unit | Plants in total |
|---|---|---|---|---|
| aluminium | primary aluminium smelter | 541 capacity | kt/yr | 4 |
| aluminium | secondary aluminium and foundry alloys | 80 capacity | kt/yr | 1 |
| aluminium | remelt and wrought-ingot casthouse | 100 capacity | kt/yr | 1 |
| aluminium | primary aluminium smelter | 133 output 2024 | kt primary aluminium (potline output) | 1 |
Totals cover the full capacity (and output) of operating plants owned by the group companies, without taking shares in jointly owned plants into account; capacity attributed to the group by share will be added in the next stage. Only values in the same unit and for the same metal are added up.
