The TENP Pipeline System: technical description

The TENP pipeline was planned at the beginning of the 70's as the German part of the pipeline system that had to supply Dutch gas to Italy. Today the TENP pipeline system, together with the Transitgas pipeline, plays a key role in the supply of Norwegian gas to the German, Swiss and Italian markets.

The pipeline runs across the German territory for about 500 kilometres, from Bocholtz, at the Dutch border, where the TENP pipeline system is connected to the Dutch network operated by Gas Transport Services, to the Swiss border, close to Wallbach, where the TENP pipeline system is interconnected with the Transitgas pipeline system.

The TENP pipeline system consists of two lines, the first of the two (36"-38") is working since 1974 and the second (40") has been completed in 2006. Part of this second line has been working from 1978.

Since 2007 the TENP system includes a share of the pipeline running from Stolberg to the Belgian border at Raeren/Eynatten, where the TENP system is connected to the Belgian network operated by Fluxys.

Today the physical direction of the gas flow is from North to South and a project is underway to make the infrastructure bi-directional so as to enable South to North movements.

The system includes 4 compression stations located at Stolberg, Mittelbrunn, Schwarzach and Hügelheim.

Tips for using search operators

Use "quotation marks" to search for a series of words or a phrase in a specific order.

Boolean operators

You can find a group of words or a phrase by using the link words AND, OR and NOT:
known as Boolean operators, these words are used to combine terms in the search field.

  • AND: All the search terms must be included in the publication. Typing in Apple AND Pear will return publications containing both the word Apple and the word Pear.

     

  • OR :  At least one of the search terms must be included in the publication. Typing in Apple OR Pear will return publications containing either the word Apple or the word Pear or both.

     

  • NOT: The term preceded by NOT must not be included in the publication. Typing in Apple NOT Pear will return publications containing the word Apple but not the word Pear.
