# Transfer of curtailed energy from the EEG-BK of NB to ÜNB — View ÜNB The BIKO forwards the transfer time series for curtailed energy calculated by the ÜNB to the BKV and the NB. If the curtailed energy changes after the transfer time series has been transmitted, the ÜNB transmits the changed transfer time series to the BIKO. The latter forwards the changed transfer time series. With this time series, all AAÜZ flowing into the EEG-BK of the NB are transferred as a total into the EEG-BK of the ÜNB. ## Process flow from the perspective of the ÜNB \nSystem diagram: Überführung der Ausfallarbeit aus dem EEG-BK des NB an den ÜNB — view of ÜNB\n\n\nCustomer backend system\n\nMACO APP · ÜNB\n\nMarket partner\n\n\n\n1.

## Process information Wording of the consolidated version, profile ch. 17.3.6.1.1, pp. 283–284.
  1. ### Preconditions For its balancing area, the NB has named a BK to which the EEG transfer time series (EUZ) are assigned. The balancing settlement of the RD measure has taken place with the EEG balancing group of the ANB.
  2. ### Results The BIKO can carry out the BKA including EUZ.
  3. ### First message The party involved on this page is itself the sender of: „Transfer time series for curtailed energy“ to **BIKO** (step 1).
  4. ### Objective The curtailed energy has been transferred from the EEG BK of the BKV (NB) to the EEG BK of the BKV (ÜNB) for every balancing area of the NB.
