First of the two tubines installed at 9 MW German wind project

The first of two N149/4.0-4.5 turbines with a nominal output of 4.5 megawatt was installed at the Wennerstorf II wind farm located roughly 30 kilometres south of Hamburg.

Originally, the Wennerstorf wind farm consisted of four turbines, each with a nominal output of 1.3 megawatts, which had been producing electricity since 2003. In 2015 the developer ABO Wind decided to repower this site with the latest technology by replacing the old turbines with new ones. In doing so, it opted for the first turbine from the Delta4000 product series, the N149/4.0-4.5: With a total installed output of 9 megawatts, the capacity of the Wennerstorf II wind farm will increase by 73 percent.

The turbines are going to be equipped with radar-controlled aviation obstruction lighting due to their total construction height of 200 meters. The obstruction lights are only activated when an aircraft flying at an altitude of below 600 metres approaches the turbines within a radius of four kilometres. This avoids the need for continuous obstruction lighting during the night.
