4.8.1 GAS TRANSMISSION AND
DISTRIBUTION NETWORK DEVELOPMENT
The construction of the Swedish transmission grid began in 1985. Three years later
the grid reached Gothenburg. In 2004, the latest major expansion was made which
led to today’s transmission grid.
The transmission grid consists of 601 km pipelines, 41 measuring and regulator
stations and six gas metering stations located in south-western Sweden. The grid is
connected to about 26,000 km of distribution grids. The system has a pipeline
interconnection with the Danish gas system with a maximum cross border capacity
of 88GWh/day. This pipeline interconnects Dragør in Denmark with Klagshamn,
Sweden. Due to Swedish legislation the gas is odourised on the Swedish side by add-
ing a special chemical in Klagshamn.
The transmission system is connected to an UGS, Skallen storage facility. This rock
cavern storage facility, characterised by high input and withdrawal capacity, has a
capacity of 10 mcm and can handle pressure in excess of 200 bar. The size of the
storage does not allow seasonal storage but is limited to peak-shaving services.
Sweden has a vulnerable supply position due to the single cross-border point in the
gas system. This weakness has been mitigated primarily by the Ellund project
(increasing capacity between Germany and Denmark). The upcoming LNG terminal
in Gothenburg and increasing biogas production will also strengthen the supply
position.
