Enercon's rating in the poll by the national wind federation, BWE, fell to 2.24 from 2.07 a year earlier on a scale from 1 to 6, with 1 as the top rating.
The country's leading turbine manufacturer still reached a high ranking in the main points, such as regular maintenance, how quickly service teams could be reached and the quality of work carried out, but its grades in the individual categories were slightly lower than last year.
