The Brandov BTS completed in 2011 is the newest and most modern border transfer station in the Czech Republic. It is located in the Ore Mountains, and joins the Czech transmission system to the German OPAL pipeline, which connects with the NORD STREAM pipeline carrying Russian natural gas via the “northern route”.
This border transfer station is located amid the peaks of the Ore Mountains, and is one of the highest points of the whole transmission system. It is an important junction point, where the pipelines of three gas companies meet. Three metering sections allow the measurement of transported gas both in the direction Czech Republic - Germany and in the reverse flow direction.
Natural gas is compressed using centrifugal compressors driven by gas turbines. The Veselí nad Lužnicí Compressor Station is equipped with upgraded gas turbines and compressor units of Czechoslovak manufacture. It is also the site of a Training Centre for compressor station shift operation staff, head operating technicians and shift operating technicians.
Along with the Kouřim CS, the Kralice CS is one of the oldest compressor stations on the transmission system. During the construction of a new line of the central section of the DN 1000 transit pipeline in 1996 the Kralice CS was retrofitted with two modern Dresser-Rand turbine compressor units with a power output of 13 MW and high thermal efficiency.
Along with the Kralice CS, the Kouřim CS is one of the oldest compressor stations on the transmission system. It lies on the “central section” of the system, via which Russian natural gas is transported to customers in Prague, central, northern and western Bohemia, and eastern and northern Germany. Its technology is the same as at the Kralice CS.
Russian natural gas passes through the Břeclav CS on the way to Germany and France. The station is equipped with upgraded gas turbines and compressor units of Czechoslovak manufacture.
This border transfer station is situated near Břeclav, where natural gas imported from Russia via the Ukraine and Slovakia enters the Czech Republic. The station was built in the 1990s after the division of the Czech and Slovak Federal Republic. It has three filtering and metering sections fitted with orifice plate measuring systems.
The Czech-Polish interconnector “STORK” has been in operation since 2011, and is the first ever gas pipeline connecting the Czech and Polish grids. About 10 km of the pipeline is in the Czech Republic, and a further 22 km continues on the Polish side, where the border transfer station is also located. The interconnector (diameter DN 500, pressure 6.3 MPa) runs along the route Třanovice – Cieszyn – Skoczów, and was co-financed by the EU under the European Energy Programme for Recovery (EEPR).
The high-pressure GAZELLE pipeline (DN 1400 / 8.4 MPa) connects the Border transfer station Brandov with the Bavarian Border transfer station Waidhaus. The pipeline with its length of 166 km brings natural gas from the so-called Northern Route and allows for bidirectional operation.
This border transfer station is located in Poland and is operated by GAZ-SYSTEM.
This border transfer station is located in Germany and is operated by Open Grid Europe.
This border transfer station is located in Germany and is operated by GASCADE.
This compressor station is located in Germany and is operated by ONTRAS.
NET4GAS operates pipelines for international transit and national transmission of natural gas with a total length of more than 3,000 km, with nominal diameters from DN 80 to DN 1400 and nominal pressures from 4 to 8.4 MPa.
The required gas pressure in the pipelines is provided at compressor stations (CS). These are CS Kralice nad Oslavou and CS Kouřim on the northern line, and CS Břeclav and CS Veselí nad Lužicí on the southern line. Total installed capacity of the compressor stations amounts to 243 MW.
Individual branches of the system are interconnected at key junction points Malešovice, Hospozín, Přimda and Rozvadov. The interconnection points of the lines are both the compressor stations and line shut-off valve stations.
Natural gas is accepted and delivered at the entry into and exit from the Czech Republic, i.e. its volume and quality are measured at border transfer stations between the Czech Republic and Slovakia in Lanžhot, between the Czech Republic and Germany in Hora Svaté Kateřiny – Sayda, in Hora Svaté Kateřiny - Olbernhau, in Waidhaus and Brandov (from the OPAL system during normal operation entry into the Czech Republic and exit from the Czech Republic into the STEGAL system). Between the Czech Republic and Poland, gas is measured at BTS Cieszyn.

Natural gas from the transmission system is further transferred via 94 transfer stations into the distribution systems, facilities of directly connected customers and gas storage facilities. Commercial metering of gas quantity is installed at all transfer stations. Gas quality is measured at 23 nodal points of the system.
