Changes to the entry, exit and trading programmes for GTS shippers

19 Apr 2018

From 1 January 2018 Gasunie Transport Services (GTS) and BBL Company (BBLC) have integrated their transport systems, as a result of which the BBL Interconnector is now part of the TTF market area. The integration of the BBL pipeline into the GTS TTF market area will have consequences for our shippers.

Every GTS shipper (all LA, LB and LC licence holders) will need to adapt the programmes they submit to GTS as part of the balancing system requirements. The reason for the required change is caused by the introduction of the trading zone which includes the TTF. The changes are summarized below.

Entry programme

In an entry programme, the GTS shipper specifies the total volume of physical entry into the GTS gas transmission network for the specific portfolio for each hour. Furthermore, the shipper specifies the aggregated volume of gas for each hour, no longer specifying the counterparty for the trades on TTF. Instead, the aggregation of all trades on TTF must be included using the shippercode GSTPTRADE we reserved for this purpose.

Exit programme

In an exit programme, the GTS shipper specifies the total volume of physical exit for the specific portfolio for each hour. Furthermore, the shipper specifies the aggregated volume of gas for each hour, no longer specifying the counterparty for the trades on TTF. Instead, the aggregation of all trades on TTF must be included using the shippercode GSTPTRADE we reserved for this purpose.

GTS shippers can still add their trade transactions to the entry and exit programmes: there is no need for them to supply separate programmes. When a shipper applies damping, it is advisable to add the aggregated trade transactions to the entry programme.

Trade programme

GTS shippers with a licence C (i.e., parties solely trading on TTF) must submit a programme to GTS. In this trade programme (per portfolio for each hour) the transfer from the GTS set of balancing to the Trading Zone (or vice versa) is represented. Contrary to the current trading programmes, these parties should no longer specify each counterparty for the trades on TTF, but only specify the aggregated volume of gas traded. Instead, the aggregation of all trades on TTF must be included using the shippercode GSTPTRADE we reserved for this purpose.

Further details can be found in document on GTS BBL integration operation aspects (link). For programme responsible parties that apply damping, it is strongly advised to test the adjusted programmes to ensure that damping will indeed be applied by GTS.

Timing

In December 2017 it became clear that a considerable number of shippers were not able to implement the required changes before 1 January 2018. To avoid problems GTS implemented a quick fix allowing shippers more time, until 1 May 2018, for the implementation. With the implementation deadline in sight we conducted a survey which shows there are still several shippers who have not yet implemented  these changes. We urge these shippers to implement the required changes because the quick fix that currently is in place will be removed by 20 September 2018 as part of a greater IT release. We offer the possibility to test the implementation of the required changes.
