Ørsted has conditionally named Siemens Gamesa Renewable Energy as the preferred turbine supplier for two offshore wind power projects in the German North Sea totaling 1,142MW.
A five-year service and maintenance agreement is included in the preferred supplier award.
The award is subject to certain conditions including Ørsted’s final investment decision, which itself is subject to the projects receiving final grid dates and final consents from German authorities. The Borkum Riffgrund 3 project will be the largest offshore project in Germany to date.
“In this new decade, we need to translate social and political ambition into tangible action and change. As a global leader in renewable energy, we are committed to helping move Germany towards a competitive decarbonization thanks to the implementation of our most advanced technologies,” said Andreas Nauen, CEO of the Siemens Gamesa Offshore Business Unit.
“We are glad to do so together with global market leader Ørsted, and to deploy our new Direct Drive offshore turbine with a 200-meter rotor at the same time.”
The final number of turbines for both projects remains to be determined. Ørsted expects the installation of Gode Wind 3 to begin in 2023, with commissioning being completed in 2024. The installation of Borkum Riffgrund 3 is expected to begin 2024, with commissioning being completed in 2025.
“Driving innovation is at the core of Ørsted’s DNA, and we look forward to once again introducing new turbine technology to the market,” said Martin Neubert, Executive Vice President and CEO of Ørsted Offshore.
”Subject to our final investment decision, we will install the new turbine on two German projects including Borkum Riffgrund 3, which will be the biggest offshore wind power plant yet in German waters, adding to the more than 1.3 GW offshore wind we have already installed in Germany. The increasingly larger turbines and projects have been key drivers in making offshore wind cheaper than newly-built, fossil-based power generation.”
A total of approximately 1.2 million German households will be served by the projects once online.
The SG 11.0-200 DD offshore wind turbine features a 200-meter diameter rotor utilizing the 97-meter long Siemens Gamesa B97 IntegralBlade. The B94 blade design has been re-used and extended to reach the new length, whereas the generator capacity remains at 11MW, as known from the SG 11.0-193 DD Flex.
The upgraded machine with the 200-meter diameter rotor provides an increase of 9% in Annual Energy Production compared to the SG 10.0-193 DD offshore wind turbine with a 193-meter diameter rotor, Siemens Gamesa said.
