Lanthan Safe Sky ensures dark nights and greater acceptance of wind energy across the board

408 wind turbines switched to dark, systems for a further 518 wind turbines already installed

  • On more than 400 wind turbines, the Lanthan Safe Sky ADLS systems switch off the night-time flashing and give residents and nature dark nights back.
  • Installation has already been completed for a further 518 wind turbines and commissioning can take place soon.
  • The pace of the implementation phase is steadily increasing and will increase significantly in the coming months.
  • Lanthan Safe Sky is looking forward to exchanging ideas with interested parties at the Wind Energy trade fair in Hamburg in Hall A1 at Stand 412 from September 27 to 30.

Walldorf, September 23, 2022

With an implementation phase that has clearly picked up speed in recent weeks, Lanthan Safe Sky (LSS) is setting new standards among providers of transponder-based on-demand night-time identification (OID): “This year has been a challenge for our team in every respect so far. The globally disrupted supply chains have massively delayed implementation and caused great frustration on all sides. We are therefore all the more pleased that we can now finally get started with the roll-out of our system,” reports Managing Director Henning von Barsewisch. 

Around 60 transponder ADLS systems on more than 400 WTGs have already been activated across Germany and are bringing back the darkness of the night for residents and nature: thanks to ADLS, the night-time lighting of the WTGs is only activated when there are aircraft in the vicinity. In addition, a further 518 WTGs are equipped with Lanthan Safe Sky technology and will go into operation in the coming weeks and months. “We have only completed a small part of our orders so far, but the speed of implementation is now increasing noticeably. By mid-2023, we will be equipping wind farms in Germany in particular. However, other countries have also become aware of the benefits of ADLS, meaning that interest in LSS is growing steadily, particularly in other European countries. In addition to initial activations – for example at the Krammer wind farm in the Netherlands – we are already in contact with customers and the relevant authorities in several countries,” explains Christian Hammer, Chief Operations Officer at Lanthan Safe Sky.

A lot has also happened within the company this year: a few weeks ago, Lanthan Safe Sky welcomed Jochen Fuglsang-Petersen, an experienced wind energy expert and long-time pilot, to the team, who will drive forward the further development and adaptation to the requirements of international markets as Head of Technology. “I am very much looking forward to this challenging task, which we will certainly master with a motivated, strong team. Demand-driven night-time marking can increase the acceptance of wind energy without compromising the level of flight safety, which is of course our top priority,” says Jochen Fuglsang-Petersen.

Interested parties from Germany and all over the world will have the opportunity to put their questions directly to competent contacts from sales and project management next week: Lanthan Safe Sky will be represented at Wind Energy Hamburg in Hall A1 at Stand 412 and is looking forward to welcoming numerous visitors.

About Lanthan Safe Sky GmbH

Lanthan Safe Sky GmbH‘s mission is to make the sky safer and nights darker. It emerged from the founders and players of Lanthan, Air Avionics and RECASE and thus combines the expertise of a leading provider of obstacle marking systems, an aviation-approved avionics system manufacturer and an experienced engineering and consulting service provider in the field of renewable energies.

The companies involved came together years ago to bring secure, cost-effective and sustainable detection technologies to market maturity with the Transponder ADLS.

They worked hard over a long period of time to create acceptance for this young technology. With success, as a broad consensus was reached: New legal regulations in countries such as Germany, but also at the ICAO, the world’s highest-ranking international civil aviation organization, allow the use of transponder ADLS technology, which is emission-free and based purely on the reception of data that every aircraft transmits anyway.
