As previous studies by ewi ER&S and the Oxford Institute for Energy Studies (OIES) showed, there are bottlenecks in the European gas transmission grid. Especially between Germany and Italy, Germany and Austria as well as between the two French market areas, bottlenecks exist. This study focuses on the question if those bottlenecks persist in future. Therefore, two scenarios of OIES with high and low Asian gas demand which influences the European LNG supply are simulated in the European gas infrastructure model TIGER. Infrastructure extensions that are needed to realize the assumptions concerning demand and supply are modelled. The results indicate that especially in the scenario with high Asian demand (low LNG imports to Europe) bottlenecks persist in the European gas infrastructure in 2030.
