The firm order includes the supply of 83 SG 11.0-200 DD offshore wind turbines and a
multi-year service contract, the turbine maker said.

The installation work is scheduled for 2024, with commissioning expected in 2025.

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 per cent in Annual Energy Production compared to the SG 10.0-193 DD offshore wind turbine with a 193-meter diameter rotor, Siemens Gamesa said.

”We are delighted to be again partnering with Ørsted in another important offshore project. This huge wind power plant featuring our SG 11.0-200 offshore Direct Drive machines will provide both clean green energy to more than one million households for decades to come, and alsomake a significant contribution towards energy security for Germany,” said Marc Becker, CEO of the Siemens Gamesa Offshore Business Unit.

The Borkum Riffgrund 3 wind farm is owned by Ørsted (50 per cent) and Glennmont Partners (50 per cent).

As part of the agreement, Ørsted will construct the wind farm under a full-scope EPC contract, perform operations and maintenance services for 20 years, and provide a route to market for the power and green certificates generated by Borkum Riffgrund 3.

The developer has already signed corporate power purchase agreements (CPPAs) for Borkum Riffgrund 3 for a total of 786 MW with Covestro (100 MW), Amazon (350 MW), REWE Group (100 MW), BASF (186 MW), and Google (50 MW) to support the final investment decision by creating a large degree of revenue certainty for Borkum Riffgrund 3.

Ørsted is also developing the 242 MW Gode Wind 3 wind farm offshore Germany in parallel with Borkum Riffgrund 3. This wind farm will feature the same turbine model.

Cadeler will transport and install the turbines on both wind farms.
