The analysis of customer groups is relevant for some settlement procedures (for example, the enhanced analytical procedure). The customer group is not a new entity but derives directly from the synthetic profiles used. This means that, in the enhanced analytical procedure, the number of customer groups to be taken into account is the same as the number of synthetic load profiles used for that period.

Partial settlement results that relate to a customer group (for example, distribution factors in the enhanced analytical procedure) must contain the reference data of the corresponding synthetic profile (the customer group) in the profile header.
