First plant to use SGT-750 turbine; full load achieved in 10 minutes
Siemens Energy announced that the cogeneration plant in Lubmin, Germany, has been officially inaugurated.
Siemens delivered an SGT-750 industrial gas turbine for the plant, which is located directly at the landfall station of Nord Stream's Baltic Sea pipeline. The company said the Lubmin plant is the first to be placed into operation with this gas turbine.
The plant operator is the Industriekraftwerk Greifswald GmbH, a joint venture of WINGAS GmbH and E.ON Energy Projects GmbH.
With an electrical capacity of 37 MW, the gas turbine can bring the cogeneration plant up to full-load operating mode in just 10 minutes, Siemens said. The electricity it generates is fed into the grid, while the waste heat from the gas turbine heats the natural gas upon its arrival at the landfall station.
The gas pressure in the Nordstream Pipeline is too high when it arrives in Lubmin; the pressure is reduced at the Lubmin Landing station to suit the onshore pipeline systems (OPAL, NEL). When the gas pressure is reduced, a drop in gas temperature occurs (Joule-Thomson effect). This temperature drop is compensated for with the exhaust heat from the SGT-750 gas turbine, the company said.
