Power generation
How the SGT-750 is helping safeguard Europe’s gas
supplies Along its route from Siberia’s large natural gas
reserves, the Nord Stream pipeline transports natural gas
through the cold Baltic Sea. Not only does the temperature of
the gas drop during transport, but the pressure also falls – from
about  bar at the Russian city of Portovaya to a maximum
of  bar in Lubmin, Germany – resulting in a challenging
situation. On the one hand, the pressure is still not low enough
for further transport, for which  bar is required. On the
other hand, the gas has already cooled down to such an extent
that a further reduction in pressure could cause the pipelines
to become iced. That’s where our SGT- gas turbine comes
in, helping ensure the smooth provision of gas to Europe with
its exhaust heat. The fact that the power generated by the
turbine is fed into the grid and can supply up to , house-
holds with electricity rounds off this success story.
