End of supply from NB to LF — NB view
The NB announces to the LF the termination of the assignment of the LF to the market location or tranche. In the course of the process
- the NB terminates the assignment of the MSB to the market location or metering location upon decommissioning of the market location.
- in the event of a decommissioning of the market location, the NB cancels
- where applicable, the assignment of the LFZ to the market location or tranche.
- where applicable, the assignment of the MSBZ to the market location or metering location.

Process information
Wording of the consolidated version, profile ch. 2.5.2.1, pp. 57–58.
Preconditions
- In the case of a consuming market location: LF is assigned to the market location.
- In the case of a generating market location or a tranche: LF is assigned to the market location or tranche. The following cases are possible:
- Termination of the assignment of the LF to a market location
- Termination of the assignment of the LF to a tranche of a market location
- Termination of the assignment of the LF to all tranches of a market location. The use case “End of supply from NB to LF” must be carried out separately for each tranche.
Results
- In the case of a consuming market location:
- The NB executes the use cases „Billing data grid usage settlement“ and „Billing data balancing group settlement“.
- Where applicable, the NB executes the use case „Beginning of the replacement supply / default supply“.
- In the case of decommissioning: If the market location is assigned to Model 2, NB ends the metering point for NGZ.
- In the case of a generating market location or a tranche:
- The NB executes the use case „Billing data balancing group settlement“.
- Where applicable, the NB executes the use case „Establishing a 100% LF assignment to a generating market location“.
- In the case of the decommissioning of a market location: If the location bundle is not decommissioned, NB informs the market partners of the locations that remain active about the change of the location bundle with the use case "master data change" (here: “Master data change originating from NB (responsible)”) (GPKE Part 4).
- In the case of a consuming market location:
Error case
Result in the error case
The LF remains assigned to the market location or tranche.
Further requirements
- Note: A market location that cannot be assigned to any LF and for which a statutory basic or substitute supply obligation under § 36 and § 38 EnWG may exist is assigned to the E/G by NB via the use case “Start of replacement supply / default supply”.
- If, as a result of the termination of the assignment, a market location can in future be assigned neither to the E/G nor to a contractually designated replacement supplier or any other LF, NB must interrupt the grid connection use at the market location.
Trigger
- Decommissioning of a market location
- the use case „Deactivation of an allocation authorization of the BKV at the NB“ has been carried out and, for the affected market location or tranche, there is no assignment to a BK with an active allocation authorization for the time period immediately following the deactivation
- for the market location, the time series type has changed as of the stated point in time, and no valid allocation authorization exists for that type
Runs beforehand: End of supply from LF to NB — these processes name the one shown here in their result.
First message
The party involved on this page sends this itself: “Announcement of the termination of the assignment of the LF to the market location or tranche” to LF (step 1).
Objective

Notes on this page
The steps are the possible messages of this process, not a sequence — the source lists neither conditions nor alternatives. The small box on the step names the own view on the left: with ← it receives, with → it sends. Collapsed steps run between other market partners. The numbers are those of the source; where one is missing, it is missing there.
