As per March 2011, we now measure the wind conditions with almost 20 own masts in the region at different heights above ground. The masts are 40 to 80 metres high. These measurements, covering so far between 1 and 6 years without any data gaps, show that we have significant energy inputs mostly from westerly and northerly wind regimes. After a long period of consecutive wind data analyses, both our calculations and a recently completed and permanently adapted wind model show mean yearly wind speeds of more than 7.0 - 7.3 m/s at hub heights of 80 - 100 metres above ground at most of our sites under development. That will mostly lead to yearly net equivalent hours (NEH) of more than 2'600 h/y, depending on the chosen turbine type and the site. These calculations and conclusions are summarized in a confidential wind report for the projects under development.
