Balance Agreement (TTF-B)

In case a shipper transports gas to domestic physical network points, he has the possibility to transfer (a part of) his imbalance risk to another shipper. To realize this he must enter in a Balance Agreement with another shipper.

In a balance agreement the balance-receiving shipper and balance-supplying shipper agree that a certain amount of gas is transferred at the virtual trading point TTF-B (301411), a network point created for this purpose. The exact amount is calculated afterwards on the basis of allocations of the balance-receiving shipper.

Shippers can enter into a balance agreement for one or more specified user categories (G1A, G2A, G2C, GXX, GVV and starting 1-1-2018 also GIN and GIS) of the balance-receiving shipper. The balance-receiving shipper will stay unchanged mentioned as PV is the connection registers of the transmission operators. For different categories different agreements can be made. It is also possible to have just a selection of user categories in the balance agreement. However it is not possible to include individual customers into the balance agreement.

Different types of balance agreements

Percentage-balance: the balance-supplying shipper supplies gas up to a agreed percentage of the physical offtake of the balance-receiving shipper per user category.

Max-balance: the allocated amount of gas on the TTF-B network point between the balance-supplying shipper and the balance-receiving shipper has an on beforehand specified upper limit.

Min-balance: the allocated amount of gas on the TTF-B network point between the balance-supplying shipper and the balance-receiving shipper has an on beforehand specified lower limit.

Own-use: the balance-receiving shipper enters a fixed amount of gas into the balance agreement. The transfer of this amount from the balance-receiving shipper to the balance-supplying shipper takes place at the TTF trading point, not at the TTF-B network point.

It is possible to combine different types, however the combination of a percentage and a fixed lower limit is not possible.

Programs, Nominations, Confirmations en Allocations

The balance agreement between shippers must be effectuated by means of sending a specific nomination message BALDOC to GTS in which both parties scope the balance agreement.

Nomination: nominations can be send up to 400 days in advance, although shippers can choose to nominate on a monthly or daily basis. It is not an obligation that both shippers in the agreement have the same nomination pattern, because matching will be performed on a daily basis applying the Zero-Rule, notwithstanding the Lesser-Rule that applies on the TTF. The confirmation will get the status “settled” when both nominations contain the same information.

NRT-process:  The balance-supplying shipper receives near real-time information about the aggregated exit portfolio insofar as the scope of the balance agreement goes. This information is shared, amongst others, in Gasport (or via B2B) per user category. The realized amounts of the balance-supplying shipper will be treated as exit allocations. For the balance-receiving shipper these realizations will be treated as entry allocations, all data will be presented in GasPort (or B2B).

Offline allocation process: The offline allocations for the TTF balance agreements are calculated at the moment that a complete set of offline allocations for the balance-receiving shipper is available. If a difference occurs between the NRT and offline date the settlement invoice will be used to settle the differences.

Program: The balance-supplying shipper specifies the total of his balance agreements in his exit programme PRODOC. There must be a split between protected users and others  in accordance with his own physical exit (GSTPPUB for protected users and GSTPOTHERB for other user categories).
