Siemens has uprated its D3 onshore platform wind turbines from 3 MW to 3.2 MW. The new SWT-3.2-101, SWT-3.2-108 and SWT-3.2-113 machines will enter serial production by the end of this year.
The turbines will be available with 101- and 108-meter rotors for IEC class IA sites and a 113-meter rotor for IEC class IIA sites. Siemens notes that the 3 MW version will remain available for project sites with lower wind speeds.
The company says improvements in the turbine control system and increased efficiency through the use of stronger magnets are the key factors that allowed Siemens to get more power out of the D3 drivetrain.
