The legal framework of liberalization of the energy markets oblige gas network operators to publish capacities at the entry and exit points of their networks. In combination with official available information about the gas transportation infrastructures and knowledge about hydraulic pipeline network simulation a model of the German gas transmission system has been realized. The ITE-GS model is an image of the major gas transport pipelines in Germany with consideration of connected storage facilities. Through the analysis of gas consumption patterns in different sectors and regions over the year, various scenarios could be defined and simulated with the model. Both nationwide network capacity and individual entry/exit capacity can be demonstrated via simulation. The current investigation illustrates several case studies about the influence on the national gas grid introducing new infrastructures (e.g. OPAL and NEL pipelines) or new gas sources (e.g. bio-methane, hydrogen and synthetic methane). Considering the logistics and integrity of a natural gas supply system it is obvious that such an extensive model on a general level could generate new knowledge because it integrates individual network models into one and avoids limiting boundary conditions inside.
