The 10 MW rating has been achieved through the incorporation of a larger diameter generator, building on the SGRE Direct Drive Generator technology. Increasing the rotor diameter to 193 metres has enabled the new turbine to offer up to 30 percent more power than its predecessor, the AEP. The 94-metre blades provide a swept area of 29,300 square metres and each blade is almost the same length as one soccer field. The annual energy production of one SG 10.0-193 DD is sufficient to supply electricity to about 10,000 European households. An offshore wind farm of 20 turbines would supply the annual electricity demand of a city the size of Liverpool.

The technology on the offshore direct drive platform allows for the re-use of most components from previous generations, providing a short time to market. The nacelles of the new offshore turbine will initially be manufactured at the SGRE factory in Cuxhaven, Germany, currently the world’s largest plant for offshore wind turbine nacelles.

The prototype is expected to be installed in 2019 with commercial market deployment expected in 2022.

“The new SG 10.0-193 DD Combines experiences and knowledge from five generations of proven direct drive technology in one 10 MW turbine” said Markus Tacke, CEO of SGRE. “A showcase of strong performance, swift market-to-time, and low risk in the offshore wind energy market”.

Andreas Nauen, CEO of the SGRE Offshore Business Unit, added that utilising proven components and concepts has enabled the company to build a strong, established value chain, with clear processes and skilled employees, leveraging a fully-developed and industrialised supply chain.

SGRE has an installed capacity of over 12.5 GW and over 3,100 offshore wind turbines in operation globally. The company is a leader in the offshore market and constantly strives to reduce the levelised cost of energy from offshore wind power.
