Route
OPAL stretches some 470 kilometres from the landing point of the Nord Stream Baltic Sea pipeline at Lubmin near Greifswald through the federal states Mecklenburg-Western Pomerania, Brandenburg and Saxony south to Brandov in the Czech Republic on the border with Germany, where it ties into the Czech transmission system operated by Net4Gas.
At Groß Köris south of Berlin, OPAL also links into the GASCADE Gastransport GmbH pipeline system which connects directly to the transmission system operated by ONTRAS Gastransport GmbH.
