The Senvion 3.4M140 is equipped with a sound-optimized blade profile and a new pitch control system to reduce turbine load. The prototype in Heckelberg can power nearly 3,000 households per year despite low wind conditions.
Due to the larger rotor compared with previous models and the 68-meter blades at these tower heights, this type of turbine is particularly suited to low-wind locations such as forested and mountainous areas.
“Senvion is focused on optimization and developing the most cost-efficient solutions for our clients,” said Jürgen Geissinger, CEO at Senvion. “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 levelized cost of energy and demonstrates that even inland low-wind locations can be profitable.”
Senvion presented the 3.4M140 turbine at HUSUM Wind in September 2015. Serial production for the Senvion 3.4M140 with hub heights of 110 and 130 meters will start toward the end of this year.
“We are very pleased to celebrate the commissioning of the first 3.4M140 EBC turbine prototype in Heckelberg. Our first installation with Senvion was carried out very quickly and so the project ended with a success,” said Heiner Röger, Managing Partner of Notus energy. “The realization of the project took place in a constructive and communicative atmosphere and laid the foundations for further common projects in the future.”
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.
