The high-pressure network operated by Erdgas Ostschweiz AG has been constantly expanded in recent times and currently features an overall length of 621 km. Further expansion of this network is planned over the next few years. The maximum permitted operating pressure is up to 70 bar, depending on the pipeline section. The high pressure network includes direct connections to the terranets BW GmbH network in the north, the Energienetze GmbH network in the east and to the transit gas pipeline in the west. Erdgas Ostschweiz AG runs two customs metering stations, used to draw and measure contractually agreed quantities of natural gas from upstream systems. It also operates some 60 pressure reduction stations, which are used to feed natural gas into our customers’ transmission and distribution networks.
