Wind Energy Development in Germany (Onshore) – Analysis of the Development in the DIBT Wind Zones Until End of 2014 C. Ender, B. Neddermann UL International GmbH, Ebertstraße 96, 26382 Wilhelmshaven, Germany, [email protected] In previous evaluations of annual statistics [1], sites were distinguished according to coastal/inland areas on the basis of federal states. For some federal states, however, this type of analysis is inaccurate because they have coastal as well as different inland sites. For this reason we have carried out a new, more differentiated evaluation of the installation data based on the classification according to wind zones as established in the DIBt guideline for wind turbines [2]. The figure below shows the regional distribution of wind zones ranging from areas with low wind conditions (wind zone 1) to wind‐rich coastal sites (wind zone 4). Zone 4 18% Zone 1 18% Zone 3 9% Zone 2 55% Share of wind turbines installed in the different wind zones, based on the number of installed wind turbines since 1982 Wind Zone 4 Wind Zone 3 Wind Zone 2 Wind Zone 1 New Installations in the Wind Zones 1800 Zone 1 Zone 2 Zone 3 Zone 4 1600 Number of Turbines 1400 1200 1000 800 600 400 200 0 Number of annual wind turbine installations in the different zones 700 500 Zone 1 Zone 2 Zone 3 Zone 2 Zone 4 Zone 3 Zone 4 450 600 500 Number of Turbines Number of Turbines 400 400 300 200 350 300 250 200 150 100 100 50 0 0 Locations of wind turbine installations in Germany Number of annual wind installations in the different zones in Lower Saxony (left) and Schleswig‐Holstein (right) Technical Issues 120,0 Germany Zone 1 Zone 1 Ø Installed Capacity, kW/Turbine 60,0 40,0 Zone 2 Zone 3 Zone 4 Germany 2.500 2.000 1.500 1.000 500 Average rotor diameter of annual new installations in the different zones and total Germany.
