GRTgaz, at the heart of Europe:

The GRTgaz network naturally places the company at the heart of Europe. France's coastlines are perfectly situated to receive LNG (Liquefied Natural Gas) imported from the Persian Gulf states and the Mediterranean and Atlantic basins.

The GRTgaz network is interconnected with the German, Belgian, and Swiss networks, as well as with the TIGF network which serves the south-west of France, a network that is itself connected to Spain.

GRTgaz therefore represents a major national sector and a transmission market with considerable potential for growth, as its network enables it to reach most European markets.

With this positioning, it can actively contribute to the objectives of the European Commission, which hopes to finalise the integrated natural gas market. The goal is to go from a multitude of national markets to one European natural gas market. Once this is achieved, all shippers will be able to send gas from any point in Europe to all of their customers, without having to worry about different norms or standards in the various countries along the way.
