Project development: It’s all about the planning

The development, construction and operation of a wind farm involves the collaboration of a multitude of companies from diff erent industries. The logistical challenges alone are highly complex and require much more than just a fl ipchart. Professional planning tools not only make the work of the planning specialists easier – without them it would be almost impossible.

the NEW turbine

With a 140 metres rotor diameter, the Senvion 3.4M140 Eco Blade Control (EBC) is the new reference for low wind speed locations. The highly efficient 68 metres blade combined with integrated serrations allows high yields and a very low sound power level. With an operational lifetime of 25 years, the Senvion 3.4M140 EBC is the solution to reduce the levelized cost of energy.
