Ørsted names Siemens Gamesa as preferred turbine supplier

Ørsted has conditionally named Siemens Gamesa Renewable Energy as the preferred turbine supplier for two offshore wind power projects in the German North Sea totalling 1142 GW.

At both the 900 MW Borkum Riffgrund 3 and the 242 MW Gode Wind 3 sites, Siemens Gamesa will deploy its new SG 11.0-200 DD offshore wind turbine. 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 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.

Approximately 3.7 million tpy of CO2 emissions will be avoided annually compared to traditional power generation.

The SG 11.0-200 DD offshore wind turbine features a 200 m diameter rotor utilising the 97 m 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 11 MW, as known from the SG 11.0-193 DD Flex. The upgraded machine with 200 m diameter rotor provides an increase of 9% in Annual Energy Production compared to the SG 10.0-193 DD offshore wind turbine with 193 m diameter rotor.

Extending on the proven offshore direct drive track record, the turbine upgrade is based on Siemens Gamesa’s deep understanding and expertise gained over five product generations since the platform was launched in 2011.

Through close collaboration with both customers and suppliers, the upgrade has been made possible by utilising the flexible IntegralBlade production setup in the Siemens Gamesa blade factories. Extensive research and development has gone into developing the new blade, with a focus on keeping blade weight increase below 3.5% even as rotor diameter increases by 3.5%.

Over 1000 Siemens Gamesa Direct Drive offshore wind turbines have been installed in all major offshore wind markets globally. They include the UK, Germany, Denmark, The Netherlands, Belgium, and Taiwan, among others. Furthermore, confirmed orders for an additional 1000 Offshore Direct Drive turbines have been received, with installations planned for the markets mentioned above and new offshore markets including the US and France.
