Yuso normally invoices the network costs for a given month on that same month's invoice. However, you may sometimes see network costs from a different period on your invoice. This always has one of the following causes:
We were not yet able to pass on the network costs for that period, or the period itself had not yet been invoiced.
We received the network costs for that period late, after the corresponding invoice had already been issued.
The distribution system operator (DSO)'s configuration for passing on network costs was set incorrectly (for example, annually instead of monthly).
The DSO issued a correction to previously reported network costs. We always settle such corrections exactly as we receive them from the DSO.
