Wind plant installation in Germany in the first half of 2007 was 25% down on the same period last year, reports German wind energy association Bundesverband Windenergie (BWE). Just 665 MW (437 turbines) came online to bring total wind capacity to 21,283 MW. "Further shrinkage of the German market will call into question the status of Germany as a turbine manufacturing nation," warns BWE's Hermann Albers. In 2006 exports accounted for 74% of German turbine sales, up from 71% in 2005, representing EUR 5.6 billion in revenues and 37% of the global wind equipment market says engineering association VDMA. With replacement of old turbines accounting for just over 10% (70 MW) of domestic sales in the first six months of 2007 and the offshore market yet to start, Albers warns that manufacturing could move abroad. Enercon, Germany's dominant turbine supplier, increased its market share to 56.5% (376 MW) compared to 31.1% (276 MW) of the 887 MW that went up in the same period last year. Vestas' share dropped to 18.7%, compared with 41.1% in the first six months of 2006. Repower Systems improved its position to 9% compared to 3.5% last year. Together, Siemens (5.9%), Nordex (4.8%), Fuhrländer (2.6%) and Gamesa (2.1%) took just over 15% of the market. GE Energy's share of the German market so far this year is just 0.4%, compared with 8.9% in the first half of 2006.
