RWE has installed two offshore substations at its Nordseecluster A wind project in the German North Sea.
The company said the platforms measure around 40 metres in length and 22 metres in height, weighing 1800 and 2500 tonnes respectively.
RWE added the substations were constructed by Chantiers de l’Atlantique and installed by SCALDIS using the heavy-lift crane Gulliver.
Nordseecluster A has a planned capacity of 660MW and is scheduled to be fully operational from 2027.
The substations will step up electricity generated by the wind turbines before transmission to the mainland grid.
Installation of 44 turbines is set to begin in summer 2026, with cable laying already underway.
The wider Nordseecluster project will reach 1.6GW, including the 900MW Nordseecluster B phase expected from 2029.
“I would like to thank everyone involved in implementing our 1.6-gigawatt Nordseecluster, which is significantly expanding RWE’s offshore wind portfolio and making an important contribution to a sustainable and reliable energy system,” said Tobias Keitel, chief technology officer of RWE Offshore Wind.
“At the ‘double wedding’, the two heaviest components were installed – a visible sign that we are making excellent progress with the work at sea.”
