Gas transportation A pipeline network for Europe

Pipelines are an important part of Europe’s gas infrastructure. Together with its European partners, Wintershall Dea has created and expanded a gas transmission system.

More than 6,000 kilometres of pipelines have been built in Europe through the collaboration between Wintershall Dea and its partners.

Securing Europe’s energy supply is a long-term task. Transporting gas via pipelines is crucially important for securing supplies and achieving climate protection goals. Together with other European companies, Wintershall Dea is helping to diversify gas transport routes and ensure a modern, low-emission and efficient energy supply.

Connected throughout Europe

Transportation activities of Wintershall Dea in Germany are managed by the holding company WIGA Transport Beteiligungs-GmbH & Co. KG. The transport subsidiaries of the holding company – GASCADE, OPAL and NEL – act independently and operate a more than 4,000-kilometre-long pipeline network through Germany which directly links five European countries. They therefore contribute to a secure energy supply for Germany and Europe and could in future support the fulfilment of European climate goals with the transportation of hydrogen and biogas. 

GASCADE Gastransport GmbH is a subsidiary of WIGA that operates a Germany-wide pipeline network of around 3,240 kilometres in length. The company’s latest project is the European Gas Pipeline Link (EUGAL) which reached its full annual throughput capacity of up to 55 billion cubic metres of gas in April 2021. The approximately 480-kilometre-long twin pipeline can efficiently and reliably transport gas from the Baltic Sea coast to Southeastern Europe.

OPAL Gastransport GmbH & Co. KG operates the Baltic Sea Pipeline Link (OPAL) runs from Greifswald to the German-Czech border and has an annual capacity of around 36 billion cubic metres.

The North European Natural Gas Pipeline (NEL) is operated by NEL Gastransport GmbH. It runs from Greifswald westwards to Lower Saxony and can transport more than 20 billion cubic metres of natural gas per year.
