Growth of the German wind market on land is likely to come to a full stop within the next five years according to a study commissioned by the environment ministry from four research institutes. Onshore wind capacity will reach 23 GW by 2010 -- an increase of 4 GW from today -- but only 600 MW will be added in the ten years to 2020. If restrictions on hub height are relaxed, 26.6 MW is possible. Meantime, in 2005 Germany installed 1049 turbines with a combined capacity of 1808 MW, about 200 MW less than in 2004. Total wind capacity is now 18,428 MW, provided by 17,574 turbines. The potential energy yield is 33.8 TWh, equivalent to around 6.7% of net German electricity consumption, says German wind consultancy, Deutsches Windenergie-Institut. Enercon was again top turbine supplier with 42% of the 2005 market, about the same sized slice as in 2004. Vestas' share fell from 30% to 26.8%, while GE Energy came third with 8.1%, a slight improvement on 7.7% in 2004. Lobby group Bundesverband Windenergie is predicting 1500 MW of new capacity for 2006, which leaves the average market size for the following four years at just over 600 MW, if the projected ceiling of 23 GW holds.
