In 2010 the gas transmission rate was 7 642 Mm 3 and the distribution rate
was 2 493 Mmn 3 , hereof 22 Mmn 3 town gas (Figure 3.104). The variation over
the time series owes mainly to variations in the winter temperature and to
the variation of import/export of electricity from Norway and Sweden.

Data on the transmission pipelines excluding offshore pipelines and on the
distribution network are given by Energinet.dk, DGC and the distribution
companies concerning length and material. In 2010 the length of the transmission
pipelines was around 860 km. Because the distribution system in
Denmark is relatively new most of the distribution network is made of plastic.
In 2010 the length of the distribution network was a round 23 400 km.
The major part is made of plastic (approximately 90 %) and the remaining
part is made of steel. For this reason the fugitive emission is negligible under
normal circumstances as the plastic distribution system is basically tight
with only minimal fugitive losses. However, the plastic pipes are vulnerable
and therefore most of the fugitive emissions from the pipes are caused by
losses due to excavation damages and construction and maintenance activities
performed by the gas companies. These losses are either measured or estimated
by calculation in each case by the gas companies. About 5 % of the
distribution network is used for town gas. This part of the network is older
and the fugitive losses are greater. The fugitive losses from this network are
