It officially entered regular operation on Thursday in the presence of Robert Habeck, Germany’s minister for economic affairs and climate action.
The wind farm features 38 Siemens Gamesa SG 8.0-167 DD turbines, including three that are fitted with recyclable blades that will be tested in real-life conditions at the site.
The blades are made using a type of resin that can be separated from other components on the turbine once they at the end of their effective working life, in order to be recycled.
After they are decommissioned, the blades will be immersed in an acid solution heated with renewable energy that will separate the glass fibre, plastic, wood, and metals they are made from.
These materials can then be used in other products from cars to suitcases.
Kaskasi is located around 35km offshore from the Heligoland in the German North sea according to Windpower Intelligence, the data and research division of Windpower Monthly.
The 342MW wind farm began producing power in August 2022 and RWE said all 38 turbines at the site had been feeding power to the grid since the end of last year.
Some tubine firms are working towards making blades - which have an effective lifespan of up to 25 years - fully recyclable in an effort to reduce waste.
Danish manufacturers Vestas announced in February it had created a recycling solution for turbine blades made from epoxy resin.
And Chinese OEM firm MingYang Smart Energy this week officially launched a 75.7m wind turbine blade it said was made from 95% recyclable materials.
