Offshore wind farm Kaskasi

Technological research and further developments in RWE Renewables' largest construction project

Green electricity to help reaching climate targets

With Kaskasi RWE is realising its sixth wind farm off the German coast.

Kaskasi is one of RWE Renewables’ major projects under construction with 38 turbines (Siemens Gamesa 9MW) and a planned installed capacity of 342MW. Located 35 km off the coast of Heligoland (North Sea), the new site will be part of the “Heligoland Cluster” together with Amrumbank and Nordsee Ost.

The first power was already produced. Once fully operational at the end of 2022, Kaskasi offshore wind farm will supply the equivalent of approximately 400,000 households with green electricity.

Project status: In construction

Research projects & innovations

RWE is driving the technological research of the offshore wind industry and is testing innovative foundations, an innovative installation technique and recyclable rotor blades at its Kaskasi offshore wind farm.

Innovative technology for offshore foundations

Steel collars increase load-bearing capacity of entire foundation

An innovative foundation technology is celebrating its premiere at RWE’s Kaskasi offshore wind farm: For the first time ever in the renewables industry special collars were installed around the monopile foundation at seabed level. The ‘collared monopile’ is a design based on a RWE patent.

Vibrating instead of hammering

Innovative installation technique for offshore foundations

In the research project "VISSKA" the partners want to develop forecast models for installing monopiles using the vibro pilling method, the associated noise emissions, and to validate these models through measurements in offshore conditions. 

RWE & Siemens Gamesa test the world's first recyclable wind turbine blade

Special resin paves the way to full recyclability of wind turbines

The 81-meter long blades contain a new type of resin whose chemical structure enables efficient seperation of this resin from other components. After the wind turbines have been dismantled at the end of their live cycle, the materials protected by the process can thus be reused, e.g. in the automotive industry or in consumer goods. This further paves the way for the complete recyclability of wind turbines.
