Throughout its existence the transmission network of GTS has been subject to continuous improvement. Soon after making the discovered on-land gas reserves available to the domestic market, the transmission network started to play an important role in cross-border transmission, enabling gas exports not only to Germany and Belgium, but also to France, Switzerland and Italy.
With the discovery of off-shore gas in the North sea, both on the Dutch Continental Shelf, but also in Norway and later Denmark, the transmission network has enabled this gas to be made available to the Dutch and European market. GTS still plays a pivotal role in the small field policy of the Dutch government.
With the ongoing liberalization of the European gas market the transmission network has continued to develop and the number of system connections with other infrastructure has grown. A large number of underground gas storages, both in the Netherlands and in Germany, is now directly connected to the Dutch transmission system. In addition, an interconnector with the UK and an LNG regasification terminal are connected to the network.
Europe is increasingly depending on the import of natural gas from sources outside of Europe. LNG plays an important role in non-EU supply, making the EU-gas market part of a global marketplace. The Dutch gas market is well-positioned for this global market, being highly interconnected with amongst others the UK-market and the presence of an operational LNG-terminal.
Over the years, GTS has developed a considerable number of products and services to promote and facilitate the gas trade and allow connected system operators to offer its services. Traditionally the GTS network is well-connected with EU-gas markets. With a connection to the network of GTS, direct access is gained to the TTF and the most liquid continental gas market in Europe, both for prompt and forward/futures trading. The high liquidity and attractiveness of the Dutch gas market is supported by and supportive of the Dutch balancing regime. Through this regime the line pack flexibility of the transmission network is made available to the market in a transparent and non-discriminatory way.
For the connection between the transmission system and a underground gas storage of LNG-facility a Interconnection agreement (IA) is concluded between the transmission- or gas production system operator and gasstorage or LNG-terminal operator. An IA is also concluded between GTS and a neighbouring transmission system operator.
