Can the composition of units in an aggregated group be changed without requiring a new prequalification?
In order for a unit type to be type-qualified, the individual units must have technical characteristics that Svenska kraftnät assesses as equivalent to those of the units already included in the prequalified group. Furthermore, the group's overall technical capability must be equal to or better than at the time of prequalification.
This means that the added units must not negatively impact the group's capability. The possibility of type-qualifying units into a group is evaluated in connection with the group's prequalification.
