The first prototype of Senvion’s 3.4M140 EBS has been installed in Heckelberg for the Notus energy Group. The prototype is equipped with a sound-optimized blade profile and a new pitch control system to reduce turbine load. Its estimated yearly power output is 10.000 GWh.
Senvion presented the 3.4M140 turbine at HUSUM Wind in September 2015. Serial production for the Senvion 3.4M140 with hub heights of 110 m and 130 m will start towards the end of this year. Due to the larger rotor compared with previous models and the 68 m blades at these tower heights, this type of turbine is particularly suited to low-wind locations such as forested and mountainous areas, as Senvion pointed out.
"The Senvion 3.4M140 EBC is one of the quietest turbines on the market and the load-reducing pitch control system ensures a cost-effective design. This development makes a significant reduction to the levelised cost of energy and demonstrates that even inland low-wind locations can be profitable", said Jürgen Geissinger, CEO at Senvion
The prototype of the new turbine has been installed for Notus energy. Heiner Röger, Managing Partner of the company stressed out his satisfaction with how smoothly the project has been realised.
The Senvion 3.4M140 is equipped with the Next Electrical System (NES), which Senvion introduced for its 3.XM series at the HANNOVER MESSE 2015. The gearbox-based concept, which features an asynchronous generator and a fully rated converter, permits stable grid feed-in and satisfies the future grid requirements in a range of markets.
