Senvion has completed the installation of the first 3.6M140 EBC (Eco Blade Control) onshore wind turbine prototype, located at the Windtestfeld Nord in Schleswig-Holstein, Germany.
The 3.6M140 EBC, designed for moderate and strong wind speeds, was installed for 4testwind GmbH. The EBC is a load-reducing pitch control system that enables optimized load management even in challenging wind conditions, says Senvion.
The turbine also features a newly designed steel tower and a larger rotor diameter of 140 meters, generating high yields even at lower wind speeds. The rotor blades are equipped with new Rodpack technology, which ensures a lighter blade design. At a hub height of 110 meters, the turbine can power up to 3,400 households per year and has an extended lifetime of 25 years, according to the company.
The Windtestfeld Nord, located near Husum, is just three kilometers away from the North Sea. This location offers ideal wind conditions for the testing and the certification of the turbine, notes Senvion.
“Senvion is committed to reducing the levelized cost of energy,” comments Jürgen Geissinger, CEO of Senvion. “With this new turbine, we have combined core product developments to create a machine that is targeted towards optimal energy efficiency. The combination of the 140-meter rotor diameter and the upgrade to 3.6 MW allows additional output at the same site. Even with the larger 68.5-meter rotor blades, the 3.6M140 EBC can be installed in the same amount of time as a smaller turbine, ensuring an effective solution for our customers.”
The wind farm owner, 4testwind GmbH, is a co-development of the iTerra GmbH & Co. KG and Betriebs und Beteiligungsgesellschaft Senvion mbH.
Senvion presented the 3.6M140 EBC turbine at Hamburg WindEnergy in September 2016. Serial production for the turbine has already begun, and further installations are planned for this year.
