terranets bw GmbH is a Transmission System Operator (TSO) for natural gas in Baden-Württemberg. More than two thirds of the towns and communities in Baden-Württemberg are connected to our grid. This means that around 7 million people in Baden-Württemberg benefit from our natural gas transmission. At the same time, we transport natural gas to Switzerland, Vorarlberg and to the Principality of Liechtenstein. We have been continually developing our natural gas transmission pipelines for over 50 years and thus play an important role in ensuring the highest level of security of supply.
Baden-Württemberg lies at the heart of Europe and is connected to many transnational natural gas pipelines. This means we transport natural gas from Norway, the Netherlands and Russia through our transmission system. We are connected to other pipeline systems via supply points.
The terranets bw transmission system has an approx. length of 2000 km. This is almost twice the length of the motorway system in Baden-Württemberg (1020 km). In contrast to our motorway system, our pipelines are invisbile. They lie under the ground at a depth of about 1m 20cm.
Along each side of the pipeline, there is a safety area of up to 5 m, the so-called protective strip. It is forbidden to build or dig in this area without our permission.
In order to transport natural gas throughout the whole of Baden-Württemberg, the gas has to be continually pushed. This is achieved using compressors.
The compressor station presses the natural gas molecules close together with the help of turbines and in this way achieves a higher pressure. This subsequently enables us to transport the natural gas over long distances. For example, from Ulm to Lake Constance.
