Tennet is delivering two transformers to a substation in Wilster in Schleswig Holstein, as part of upgrades that will integrate more offshore wind into the German grid.
The two direct-coupling transformers will connect the 380kV portion of TenneT’s network to the 110kV portion of Schleswig-Holstein Netz’s grid.
The structures, each weighing 285 tonnes, will complete the final portion of their journey overland to Wilster from 23 to 26 April.
The Wilster upgrade in the district of Steinburg will transform it into a critical network node for the German and European power grid and will support increasing levels of renewables penetration, TenneT said.
In addition to connecting to the subordinate network of Schleswig-Holstein Netz, the new transformers will also connect the Wilster substation to the Nordlink interconnector between Germany and Norway and the planned SuedLink, which will transport power between Germany’s north and south regions.
ABB made the transformers at its facility in Bad Honnef near Bonn, which were delivered to the port of Rotterdam and, from there, to Elbe port in Brunsbuttel.
