Vattenfall will use Siemens Gamesa’s new upgraded 11MW DD-193 turbine for the 750MW Hollandse Kust Zuid 1&2 offshore wind farm off the Dutch coast.
The companies announced the agreement to extend the Hollandse Kust Zuid turbine supply to include zone 1&2 in addition to 3&4 at the WindEurope Offshore 2019 Conference & Exhibition in Copenhagen.
Vattenfall said the Hollandse Kust Zuid zone is now planned to be fitted with approximately 140 machines.
This capacity upgrade, available under certain site conditions, means that fewer turbines are needed to generate the same amount of energy, the company said.
“This will reduce installation, operations and maintenance costs and thereby contribute to further reductions in levelized cost of energy for offshore wind,” it added.
Installation is planned for 2022, with the project to be fully operational a year later.
Vattenfall head of business area wind Gunnar Groebler said: “By deploying one of the largest and most efficient turbines ever for the first subsidy-free offshore wind farm to date, Vattenfall is underlining its position as a leader in the offshore wind industry.
“It’s a major step for Vattenfall in realising its mission to enable fossil free living within one generation.
“Using their newest turbine variant, highlights our strong and long-standing partnership with Siemens Gamesa.
“This milestone follows an intensive, open tendering process which resulted in a choice for Siemens Gamesa after they entered the most competitive bid.”
Siemens Gamesa offshore business unit chief executive Andreas Nauen said: “Our robust cooperation with Vattenfall becomes even more powerful with this conditional order.
“The newest version of our largest offshore Direct Drive machine is now setting the benchmark for turbines in subsidy-free offshore wind power projects.
“We’re thankful for the trust Vattenfall has placed in us to deliver the high levels of safety, reliability, and performance which they value so highly.
“Delivering clean energy for generations to come at a low levelized cost of energy is a joint target which we’re committed to achieving together.”
In July 2019, Vattenfall won the tender to build Hollandse Kust Zuid 3&4.
In March 2018, a permit had already been awarded to Vattenfall to build Hollandse Kust Zuid 1&2.
The development of the wind farm is subject to certain conditions, including Vattenfall’s final investment decision.
