Restoration of grid connection use (reconnect) at the instruction of LF — View MSB
In accordance with the grid usage contract (supplier framework contract) concluded between the LF and the NB, the LF instructs the NB to restore the grid connection use at the named market location of the AN supplied by the LF without delay. The NB checks the conditions on site on the day of the reconnection and, where necessary, makes several attempts to restore the grid connection use. The NB informs the LF, where applicable the MSB and where applicable the ÜNB about the result of the reconnection order.

Process information
Wording of the consolidated version, profile ch. 3.5.2.1, pp. 109–110.
Preconditions
- The disconnected market location is assigned to LF.
- The grid connection use is interrupted by means of the use case „Interruption of the grid connection use (disconnect) on the instruction of the LF“. It is therefore a consuming market location.
- The costs of the reconnection are charged to the LF as part of the disconnection.
Results
The grid connection use via the affected market location is possible again.
Error case
Result in the error case
- The grid connection use via the affected market location is still not possible.
- LF and NB clarify the further procedure bilaterally; if necessary, the LF restarts the use case “Restoration of the grid connection use (reconnect) at the instruction of the LF”.
Error cases
The grid connection use is not interrupted by means of the use case “Interruption of the grid connection use (disconnect) at the instruction of the LF”.
Further requirements
- The restoration of grid connection use at a start of supply is carried out via the use case "Restoration of grid connection use at start of supply".
- The extent to which MSB participates in carrying out the reconnection depends on whether MSB has granted NB general consent to carry out the disconnection/reconnection and, if such consent has not been granted, on the content of the consent from process step 4 “Response to request” of the use case “Interruption of grid connection use (disconnect) on the instruction of LF”. If the reconnection of the market location is carried out with the participation of MSB, these steps take place bilaterally outside this process standardisation.
- Cancellations of a reconnection order are presented in the use case “Cancelling the interruption and restoration of grid connection use on the instruction of LF”. A successful cancellation of a reconnection order ends the use case described here.
Trigger
Runs beforehand: Cancellation of the interruption and restoration of grid connection use on the instruction of the LF — these processes name the one shown here in their result.
First message
NB sends “Information on the reconnection order” (step 3). From here on, it is the turn of the party involved on this page.
Objective
The grid connection use via the affected market location is possible again.
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.
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.
For the check identifiers of these steps there is no test case in the test data set; the »Try it out« button of the write interface therefore offers no body.
