BNetzA on calculation of the intensive network use


Decisive for the network charge calculation of the atypical network use is the Bundesnetzagentur's documents from January 1st, 2014. End consumers were offered the respective agreements for a network charge reduction that is based on the purchasing habits and the connection situation of the end consumers.

Since the established network charge reductions are based on the previous year's purchases, there is a negative settlement during the course of the year. Along with the end of year settlement, there is a final assessment in accordance with the approved calculation system taking into consideration the actual consumption behaviour of the end consumer in the billing time period.
