Press release: Light:Guard covers one seventh of Germany with BNK

Light:Guard GmbH has currently installed around 450 transponder receivers for demand-controlled night marking. These receivers cover almost all of Germany with their reception radius. 50,000km² of this has already been measured and certified in accordance with the AVV. This corresponds to one seventh of Germany or the area of Lower Saxony and Saarland combined. New ADLS systems can be put into operation immediately on this area.

On-demand night marking (BNK) is a technology that can be used to reduce the flashing of wind turbines to a minimum. Light:Guard is one of the leading providers in this field. This works by the BNK system monitoring the airspace around a wind farm. Only when an aircraft is nearby are the obstruction lights of the systems activated. The signals are sent and received via transponders.

The transponder receivers of the Light:Guard are mainly located in contiguous areas, which are referred to as clusters. Most of these areas have already been surveyed. Surveying is the site-specific proof of the functionality of an ADLS system or receiver. This is required by the authorities so that BNK can be activated.

"The construction and measurement of this infrastructure took a very long time. New wind farms can be integrated very quickly into the existing infrastructure for this purpose. You can imagine it something like district heating expansion," explains Light:Guard Managing Director Willi Lehmann. "Thanks are due to the project developers, who have placed their trust in us from the very beginning."

80% of the wind farms that Light:Guard equips with ADLS have already been surveyed. These parks will soon receive a certificate and can be switched dark. That's around 3000 wind turbines where the light:guard system will then be active. The deadline for equipping with ADLS expires at the end of the year. According to this, there is a risk of high penalties for non-compliance.

However, wind farm operators can benefit from the infrastructure that has been established. Because: in areas already covered, neither an installation of a receiver nor a survey is necessary.

This not only saves costs, but also considerable time: "Anyone who has systems located in one of our surveyed areas can receive ADLK from us in eight weeks," explains Felix Weiss, Sales Manager at Light:Guard. "We can quickly find out whether this is the case with a short inquiry with us. If so, we guarantee installation and certificate within eight weeks."

Wind farm operators who do not yet have an ADLS system would thus have economic security in good time before the deadline. This applies to both existing and new systems. Here, too, demand-controlled night marking must be available when commissioning.

Light:Guard is hosting a webinar on the topic of ADLS for new systems on 25 June. Interested parties can register free of charge via this link: https://events.teams.microsoft.com/event/598b6b2c-5999-40c6-b527-c7371ebfbfdf@853d5ae8-e266-4be5-9d29-9a3e344aa8c1
