‘DD Flex’ boosts Siemens Gamesa turbine to 11 MW

Siemens Gamesa Renewable Energy has expanded its product portfolio with the launch of the ‘DD Flex’ concept and the SG 11.0-193 DD Flex offshore wind turbine.

Siemens Gamesa offshore business unit chief executive Andreas Nauen said, “The SG 11.0-193 DD Flex is another example of how Siemens Gamesa constantly works to improve performance and provide greater value for our customers, ratepayers and society-at-large.

“Digitalisation allows us to increase the capacity of our largest machine to 11 MW, boosting its annual energy production, while keeping the levelised cost of energy down.

The SG 11.0-193 DD Flex offshore wind turbine has a 193-m diameter rotor utilising 94-m long Siemens Gamesa B94 Integral Blades. What the company described as “constant digital observations are processed by the control system, increasing capacity up to 11 MW.”

The company only recently unveiled the nacelle for its new 10-MW offshore wind turbine. Assembly of the prototype nacelle for the SG 10.0-193 DD was completed at its workshop in Brande. The prototype is due to begin testing at Østerild in Denmark shortly. The nacelles of the new turbine will initially be manufactured at the company’s factory in Cuxhaven, Germany.

The 10-MW turbine will have 30% greater annual energy production than its immediate predecessor, the SG 8.0-167 DD. When it first announced details of the turbine in January 2019, the company said the 10-MW machine will be market-ready in 2022 following creation of a prototype in 2019.
