Siemens Gamesa has received a firm order to supply wind turbines to Vattenfall for the Hollandse Kust Zuid (HKZ) wind farm located on the Dutch coast, with a total capacity of approximately 1.5 GW.
The firm order includes the supply, delivery and installation of 140 offshore wind turbines SG 11.0-200 DD. The offshore wind turbines will be installed in early 2022 and the project is expected to be fully operational by 2023.
The Swedish offshore wind developer opted for Siemens Gamesa’s 11 MW turbine model with a 200-metre diameter rotor, and not the SG 11.0-193 DD Flex model with a rotor diameter of 193 metres, as initially disclosed.
The SG 11.0-200 DD offshore wind turbine features 97-metre Siemens Gamesa B97 Integral Blades. The B94 blade design, used for the SG 11.0-193 DD model, has been re-used and extended to reach the new length, while the generator capacity remains at 11 MW.
The upgraded machine with the 200-metre diameter rotor provides an increase of 9 per cent in annual energy production compared to the SG 10.0-193 DD model.
