VNB TenneT - LF/BKV

Overview of market processes

Challenges of the DSO with regard to the LF/BKV

The distribution system operator (DSO) ensures in each case that the supplier (LF) receives all information on the feed-in and draw-off points assigned to it in the delivery month on time. Only in this manner can the LF determine the necessary energy quantities and their provision. The balancing group manager (BKV) examines the compliance of the previously granted allocation authorizations (master data), as well as energy quantities determined by the DSO (transaction data). This is based on the supplier time series totals.
