Gas infrastructure in Austria

The Austrian gas grid is a historically grown system which, due to its location, represents a central hub for the distribution of gas in Europe.

The Austrian gas grid consists of different pipeline levels:

  • Transmission pipelines for the import and export of gas by means of high-pressure pipelines.
  • Level 1 distribution pipelines for the supra-regional transport of gas in Austria
  • Level 2 and 3 distribution pipelines for regional distribution to end customers.

In addition to the transmission and distribution grid, gas storage facilities with more than 97 TWh of storage capacity and natural gas and biomethane production plants are also key parts of Austria's gas infrastructure.

The Austrian gas grid

The Transmission grid

The Austrian transmission network only runs through the Market area East and comprises approx. 2,000 km of high-pressure pipelines. The Trans Austria Gasleitung (TAG) and the West Austria Gasleitung (WAG) form the main axes in the Austrian transmission system.

AGGM is responsible for coordinating network control as well as network and balancing energy management in the transmission network.

The Austrian Distribution network

The Austrian Distribution network covers all market areas (East, Tyrol and Vorarlberg) and has a total length of approx. 44,000 km.

Level 1 distribution pipelines are used for supra-regional gas transport and large-scale customer supply. Gas storage facilities are connected to the Level 1 distribution pipeline network. As the distribution area manager, AGGM is responsible for controlling the Level 1 distribution network.

The distribution pipelines of level 2 and 3 supply end customers and companies with gas. The majority of end consumers are subsequently connected to the higher-ranking gas network via low-pressure pipeline systems. The pipelines of distribution network level 2 and 3 are controlled by the network operators.


Hydrogen transport in the Austrian gas network

The Austrian gas network has sufficient capacity for the future transport of renewable gases. Only 300 km of new gas pipelines need to be built so that hydrogen and methane can be transported in parallel in the future. The remainder will be made possible by repurposing 1,400 km of existing gas infrastructure.
