Launched at the WindEnergy Hamburg event, Siemens said the new SWT-3.3-130 turbine would be available from 2017.
The German manufacturer said the direct-drive turbine's components, such as the bedplate and yaw drive, have been strengthened to accommodate the 130-metre diameter rotor. The generator and rotor hub have also been updated.
Siemens' head of onshore wind for central and southern Europe, Hannes Reuter, spoke to Windpower TV about the turbine at WindEnergy Hamburg.
"[Low wind] is a competitive market but it's one of the biggest markets. The low-wind market in Europe is 70% of the market," said Reuter.
The new turbine is part of Siemens' D3 platform, which includes the SWT-3.0-113 and the SWT-3.2-113.
Along with longer blades, it also features a new cooling system integrated into the nacelle, said Siemens.
