Vattenfall and Siemens Gamesa have joined forces to deploy the new SG 10.0-193 DD turbines at the Hollandse Kust Zuid 1&2 offshore wind farm in the Dutch North Sea.
Siemens Gamesa said it is in final negotiations to secure the contract for the supply of 76 of its 10MW turbines for the Hollandse Kust Zuid 1&2 project.
In case Vattenfall wins the tender for Hollandse Kust Zuid 3&4, Siemens Gamesa would also be selected to provide the 10MW turbines, subject to the final investment decision. The wind farm would include 152 units in total.
"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," said Gunnar Groebler, Vice President and Head of Business Area Wind at Vattenfall.
"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".
The turbines are the latest generation on the market and will increase the efficiency by 30%, Siemens Gamesa said, adding that they are fitted with 94m long blades capable of generating more capacity per rotor lap than older, smaller turbines.
Last year, Vattenfall won the tender to build Hollandse Kust Zuid 1&2, the first non-subsidised wind farm in the Netherlands. Initial preparations are now underway, with project completion expected in 2023.
