GASCADE has been planning, building and operating one of Germany's largest gas transmission networks for more than two decades. The system directly connects five European countries, providing secure energy supplies to Germany and Europe. The large quantities of energy require a lot of space. Pipelines up to 140 cm in diameter carry natural gas flexibly to over 100 exit points. The GASCADE pipeline system ships more than 100 billion m³ of natural gas every year, which corresponds to about a quarter of the natural gas consumption in the European Union.
