01The German Wind EnergyAssociation - BWE


The German Wind Energy Association - BWE• Largest renewable energy association worldwide• 20.000 members: manufacturers, suppliers, owners, investors, lawyerstechnical experts etc.• 15 national associations, 41 regional associations, 10 advisory boards,8 owner platforms, 6 Workshops• Activities• Political communication and lobbying on the federal, state and regional levelas well as on the intl./EU level (member of EWEA, GWEC, EREF und WWEA)• Public relations• Seminars, workshops, conferences• Wind market overviews• Publisher of the leading professional renewable energy journal “neue energie”and “new energy”

04 BWE ServiceSatisfaction Survey


BWE Service Satisfaction SurveyMain Idea• Identification and resolution of problems between owners and manufacturersNeeded: transparency on the service market, which helps theowners and the service providers as well• Advantage for the owners: assistance for the choice of the service provider• Advantage for the service providers: unvarnished and realistic statement abouttheir own service quality


BWE Service Satisfaction Survey 2010 (neueenergie 03/2011)• 2055 questionnaires were sent to owners registered in the German Wind EnergyAssociation• 824 complete questionnaires for 2.906 wind turbines were returned andassessed• The evaluation of the results was based on the number of questionnaires, notthe number of turbines evaluated• Questionnaires were evaluated in 3 categories, depending on the age of theturbine: still under warranty, less then 6 years, six or more years• Only companies for which at least 10 questionnaires were returned wereincluded in the evaluation

05Conclusion


conclusion• The aim = 55.000 MW until 2020: this means 3.000 MW/a• Strong growth between1998-2002: plus 46 %/a• Willingness to switch the service provider between 20 und 40 % (exceptEnercon)• Manufacturers: completion and quality of their work performed better than theprice-performance ratio• Independent service provider: offering more varied services not alwaysbetter, cheaper• Good communication between owner and service provider is the first step toclear problems or – even better - to avoid them• Desirable: fixed contact person/ no service hotline!!!• Desirable: focusing on certain types of wind turbines, experience
