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.
The plants of the group companies have no capacity or output with a unit in the register.
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.
