Siemens launches 10 MW offshore WTG

21 January 2019

Siemens Gamesa Renewable Energy has launched the company’s first 10+ MW offshore wind turbine. Siemens says that the new model, a direct drive unit designated SG 10.0-193 DD, is based on the experience of previous generations of the model, and builds on proven technology 'for maximum energy yield at all wind speeds'. It offers ‘the same reliability while improving profitability’. The prototype is expected to be installed during 2019 with commercial market deployment expected in 2022.

The 10 MW rating is made possible through a larger generator diameter, building on the proven SGRE Direct Drive generator technology. By an increase in rotor diameter to 193 metres, this new wind turbine offers up to 30% more annual energy production than its predecessor, the SG 8.0-167 DD. Its 94 metre long blades provide a swept area of 29 300 sq metres..

The technology on the offshore direct drive platform allows for the re-use of most components from previous generations, which means a short time to market.

“Utilising proven components and concepts provides us with a strong, established value chain, with clear processes and skilled employees ready to go, leveraging on a fully-developed and industrialised supply chain,” commented Andreas Nauen, CEO of the SGRE Offshore Business Unit.

The nacelles of this new offshore wind turbine will be initially manufactured at the SGRE factory in Cuxhaven, Germany.

Andreas Nauen: “The levelised cost of energy from offshore wind continues to decrease as industry scale and performance grow. New markets are developing across the globe, all of which require cost-efficient, reliable, and clean power for generations. The SG 10.0-193 DD enables us … to meet these needs in close co-operation with our customers, stakeholders, and society-at-large.”
