How to Handle Sequential Transactions during a Transfer of Use?

Modified on: Wed, 6 Apr, 2022 at 10:13 AM



When the operator TAG (Trans Austria Gasleitung) starts using PRISMA for managing its capacity, balancing groups will have to be allocated directly on the PRISMA platform. 

To know how to do that, please refer to How to Manually Allocate Your Capacity to a Balancing Group?

With respect to transfer of use transactions on the secondary market, you will have to keep in mind who should perform the allocation to the correct balancing groups.

More information can be found here below.


The operator TAG allows transfer of use transactions on the PRISMA platform, which will be a result of one of the following scenarios:

  • 1-to-1 A>B>C: shipper A makes a transfer of use to shipper B for 1000, then shipper B can transfer 1000 to C.
  • N-to-1: A+D>B>C: shipper A makes a transfer of use to shipper B for 1000 and shipper D makes a transfer of use to shipper B for 500. Then, B makes a transfer of use of 1500 to C (aggregation of transfer of use). 

In terms of reference to the parent transaction, you will be able to:

  • make a direct reference to an existing trade (primary/secondary) from the portfolio. In such case, the system will automatically check that the child transfer of use complies with the parent transfer of use (for example, amount of capacity and/or runtime),


  • insert a text reference / omit the reference. In such case, no automatic validation is performed. In addition, no further confidential information can be retrieved from parent trades. For instance, it is possible to mention 2 parent trades that would have been aggregated (A+D > B > C, see below).


Please remember that it will remain your duty and responsibility to ensure that the publication is correct, as TAG GmbH will not perform any verification/validation steps in case number two.


Note: The allocation to the balancing group in case of transfer of use remains a responsibility of the capacity holder (parties A/D).
