Pending final developments, Siemens Gamesa will supply its new SG 10.0-193 DD turbines for Vattenfall’s Hollandse Kust Zuid 1&2 and Hollandse Kust Zuid 3&4 projects. The Hollandse Kust Zuid 1&2 project are claimed to be the first zero subsidy offshore wind farms in the world.

Siemens Gamesa and Vattenfall are in final negotiations for the contract to supply the SG 10.0-193 DD offshore wind turbines for the Hollandse Kust Zuid 1&2 project. The company will also supply the 10MW turbines for Hollandse Kust Zuid 3&4 project, if the tender is awarded to Vattenfall, subject to final investment decision.

For the Hollandse Kust Zuid 1&2 project, about 76 turbines will be installed.

As per the turbine-maker, its new SG 10.0-193 DD combines the experience and knowledge from five generations of direct drive technology in one 10MW turbine. The latest product from the company is claimed to offer low-risk and high performance.

The 193m diameter rotor has blades that are 93m long. The annual energy production by the turbine is up to 30% higher compared to its predecessor the SG 8.0-167 DD.

Siemens Gamesa Offshore Business Unit CEO Andreas Nauen said: “We look very much forward to increasing our collaboration and teamwork with Vattenfall through these projects. Vattenfall once again demonstrates their confidence and interest in our products.”

Last September, Vattenfall secured a permit for building the first subsidy-free wind power plant, Hollandse Kust Zuid 1&2. Work on this wind farm has already started and it must be realized in 2023. This wind farm will generate enough electricity to power nearly 1.5 million average European households, annually.

Vattenfall vice president and business area wind head Gunnar Groebler said: “Due to the increased capacity, we require fewer turbines to be placed at Hollandse Kust Zuid which clearly reduces the environmental impact of this wind farm compared to earlier ones.

“Larger turbines and greater availability also lead to major advantages in terms of electricity generation, which is particularly important in a subsidy free environment. Having fewer turbines to install also means lower costs and fewer risks during the installation process.”
