This power station in Wilhelmshaven, with its electrical output of up to 800 megawatts, has been built to supply approximately 5.5 billion kilowatt-hours (kWh) of electricity per year. In common with many power station construction projects on Germany’s North Sea coast, the varying soil conditions in the area presented a particular challenge. Another of the project’s many special features was the crossing underneath the local coastal protection embankment by pneumatic shield tunnelling.
