Master data exchange

Metering point formation, deactivation/activation process

Master data for balancing group totals must be activated before the delivery month. The minimum deadline of 2 working days before sending transaction data should only be used in exceptional cases! The signing of the allocation authorization as an annex to the allocation agreement is required before activation.

On the creation of metering points:  

Section 4.2.3. MaBiS: “... The metering point names must be formulated according to the BDEW document “MeteringCode 2006” (Edition of May 2008); metering point names not yet currently MeteringCode-compliant must be revised accordingly, insofar as possible …” 

and section 1.3.2. MaBiS: “… if reactivated, the same metering point name shall be used again.”

This means that:

  • Each metering point name and each metering point is unique.
  • The use of identical metering points for different time series types is not permitted (e.g. LGZ to supplier and LGS to BIKO).
  • A metering point activated in a master data packet can usually no longer be changed in the future, even after deactivation.

Important note:

Only master data for balancing group totals may be exchanged which have been agreed to by both parties to the contract in the context of an allocation authorization / agreement. If deactivated, the allocation authorization / agreement must also be cancelled in accordance with the named deadlines.

Erroneously activated metering points for balancing group totals must be terminated without delay at the next possible date (standardized deactivation process) and sent to the BIKO with 0 time series. If reactivated, the same metering point must be used.
