Siemens Gamesa Renewable Energy (SGRE) has recently launched the SG 10.0-193 DD, the company’s first 10+ MW offshore wind turbine. This wind turbine aims for maximum energy yield at all wind speeds, and higher reliability so as to improve profitability and reduce the risk for customers. The turbine has a larger generator diameter so as to achieve the 10 MW rating, and builds on the proven SGRE Direct Drive generator technology. The Direct Drive technology platform allows SGRE to reuse most components from its previous-generation turbines in order to achieve a shorter manufacturing time.
The wind turbine has 94 metre long blades, about the same length as a soccer field, which can provide a swept area of 29,300 m². It has a rotor diameter of 193 metres, and can offer up to 30 per cent more annual energy production than its predecessor, the SG 8.0-167 DD. As per the company, the annual energy production by one of these wind turbines is enough to power around 10,000 European households. Hence, an offshore wind farm comprising 20 SG 10.0-193 DD wind turbines can meet the electricity consumption of a city like Liverpool. The nacelles of this new offshore wind turbine will be initially manufactured at the SGRE factory in Cuxhaven, Germany, and the company expects to install its prototype this year itself.
