Nordex and Danish radar specialist Terma have had an aviation obstruction lighting system certified for use on wind farms. 

Nordex said it will start production of the system starting in the fourth quarter of this year, initially for the German market.

The company said that in the medium term the product will be extended to international markets.

The system is based on radar and can monitor the surrounding airspace within a radius of 18km, said Nordex.

If any flying object approaching the wind park is detected, the aviation obstruction lighting system is activated, the company said.

Nordex added that the system is capable of detecting all types of flying objects, whether they are equipped with transponders or not.

The partners have trialled the lighting on turbines of the Delta generation installed at the Janneby wind farm in northern Germany.
