# Transmission of the monthly curtailed energy transfer time series (AAÜZ) — ANB view The ANB delivers the curtailed energy transfer time series for the time period under consideration to the BIKO; the BIKO forwards the monthly AAÜZ to the BKV (of the LF). The BKV have received the aggregated AAÜZ and check them. The curtailed energy per TR is aggregated per market location and totaled across all market locations of the suppliers of the balancing group. ## Process flow from the perspective of the NB (ANB) \nSystem diagram: Übermittlung der monatlichen Ausfallarbeitsüberführungszeitreihe (AAÜZ) — view of NB\n\n\nCustomer backend system\n\nMACO APP · NB (ANB)\n\nMarket partner\n\n\n\n1.

## Process information Wording of the consolidated version, profile ch. 17.3.3.3.1, pp. 257–258.
  1. ### Preconditions - Master data has been exchanged. - Curtailed energy has been determined by the grid operator per balancing group (right of first proposal).
  2. ### Results - In balancing terms, the BKV (of the LF) of the installation is placed as if the redispatch measure had not taken place. - The balancing group settlement for the BKV (of the LF) can be carried out. - The BKV (of the LF) checks the monthly AAÜZ.
  3. ### Further requirements The BIKO books the AAÜZ into the redispatch BK of the BKV (of the NB).
  4. ### First message The party involved on this page is itself the sender of: „Monthly AAÜZ“ to **BIKO** (step 1).
  5. ### Objective The monthly AAÜZ determined by the grid operator is available to the BIKO and to the BKV (of the LF).
## Other views of the process The same process through the eyes of the other parties involved: the same steps, each read from their point of view. - [View NB](/en/prozessdoku/202604/NB/MaBiS-uebermittlung-der-monatlichen-ausfallarbeitsueberfuehrungszeitreihe-aauez) — NB - [View BIKO](/en/prozessdoku/202604/BIKO/MaBiS-uebermittlung-der-monatlichen-ausfallarbeitsueberfuehrungszeitreihe-aauez) — BIKO - [View BKV-LF](/en/prozessdoku/202604/BKV/MaBiS-uebermittlung-der-monatlichen-ausfallarbeitsueberfuehrungszeitreihe-aauez) — balance responsible party of the supplier · market role BKV *The steps are the **possible** messages of this process, not a sequence — the source lists neither conditions nor alternatives.
