Structural characteristics

terranets bw´s high-pressure pipeline network has operating nominal pressures of up to 80 bar. It extends over a total length of around 2,700 km and transports gas to approx. 300 network interconnection and exit points.

In this hour, downstream grid operators and industrial customers simultaneously withdrew a total volume of 33,851 MWh/h from the transmission system of terranets bw. The annual energy withdrawn in the financial year 2021  amounted to 116,721,306 MWh.

We transport only H-quality gas. The calorific value at the entry and exit points ranged between 9.45 kWh/m³N and 11.77 kWh/m³Nh in the financial year 2021 .

Further information on the structural characteristics of the network of terranets bw are available as downloads.
