Siemens Gamesa launches serial production of 11MW offshore wind turbine

Siemens Gamesa has started serial production of its SG 11.0-200 DD offshore wind turbine.

The first serially manufactured nacelle left Siemens Gamesa’s factory hall in Cuxhaven, northern Germany today (14 January), and the first turbine has been assembled.

It is due to supply its 11MW turbines for Vattenfall’s 1500MW Hollandse Kust Zuid Hollandse Kust Zuid (1500MW) OffshoreNetherlands, Europe Click to see full details project in the Dutch North Sea, which is due to be the world’s first subsidy-free offshore wind farm.

Siemens Gamesa first unveiled an 11MW offshore wind turbine in November 2019, and announced an upgraded version with a 200-metre rotor in March 2020.

Since then, the European manufacturer has announced a 14MW turbine, with a 15MW power mode, installed a prototype and produced first power from it.

Siemens Gamesa  began converting and upgrading the Cuxhaven plant in northern Germany in summer 2021 to prepare it for serial production of the next generation of its offshore wind turbines, with power ratings of 14MW.

It first opened its Cuxhaven plant in 2017, and manufactured the first nacelle there in February 2018.

Between 2018 and 2019, the manufacturer produced 7MW turbines in Cuxhaven, and produced more than 400 8MW turbines until summer 2021.

About 600 workers are employed at Cuxhaven, and the facility supplies offshore wind farms around the world.
