Wind farm owners/operators in Germany are retrofitting wind turbines to equip them with a lighting system that will switch on only after an aircraft is detected in a wind farm’s proximity, as new law on light pollution and aeronautical obstruction lighting systems will go into effect next year.

As reported in August, Nordergründe is the first German offshore wind farm to have an Aircraft Detection Light System (ADLS) fully installed and officially approved, and is also the first offshore wind farm in the world to achieve this, according to Deutsche Windtechnik, the company that performed the upgrade.
