Intelligent Aviation Radar Minimizes Visual Impact of Vestas Wind Power Plants
Smart approach to protect the surrounding environment
The main feature of OCAS is a powerful radar system. Sited at the wind power plant, radars scan the surrounding area for nearby aircraft. If an aircraft is detected, the radar-system tracks its heading, speed and altitude and gauges whether or not the aviation lights on top of the wind turbines should be turned on. Once the aircraft has safely passed the site, the lights are automatically switched off again, thereby minimizing the visual impact on the surrounding environment.

A proven and tested technology
Vestas acquired the technology from Norwegian radar specialists OCAS AS in October 2011. OCAS is approved by aviation authorities in the US, Canada, Norway and Sweden and is already installed at more than 60 sites throughout Europe and North America. However, it is the first time Vestas will supply the system – in this particular case for the Swedish wind power plants Gansparken, Näsudden väst and Stugyl. The wind farms are owned by 700 smaller companies and private owners, among others Wickman Wind AB.

Creating solutions through dialogue with locals
“The three wind farms, now complemented with Vestas’ radar-controlled aviation lights, have been developed in close collaboration with the neighbouring residents. The only concern they have had has been related to visual impact caused by the aviation lights. This concern has now been mitigated with the installation of the OCAS system and we are receiving a lot of positive feed-back from the locals”, says Andreas Wickman, CEO, Wickman Wind AB.
