Cross-border innovation: Lanthan Safe Sky brings ADLS technology from Germany to the Dutch coastal region

• More than 160 wind turbines in the region equipped with transponder-based Aircraft Detection Lighting System
• Joint project by Lanthan Safe Sky with Westermeerwind, NOP Agrowind, RWE, and Ventolines – successful technology transfer strengthens acceptance of wind energy
• Land-based installation enables operation without offshore work for turbines located in the IJsselmeer

The project marks a technological milestone – because although some of the turbines are located in the IJsselmeer, the hardware was installed entirely on land, meaning that no work was required on the water. This significantly reduces installation and service costs and demonstrates how ADLS technology can be efficiently implemented even in challenging nearshore environments.

The Noordoostpolder project consists of three different wind farms: Westermeerwind with 48 wind turbines (near shore), NOP Agrowind with 26 Enercon turbines and Zuidwester from RWE, with 12 Enercon turbines and is managed by consultancy firm Ventolines. “The cooperation with all parties involved was extremely professional and collaborative. Together, we have implemented a solution that is technically convincing and at the same time strengthens the acceptance of wind energy among the general public,” says Henning von Barsewisch, Managing Director of LSS.

In the region – including the vicinity of the Windplanblauw and Alexia wind farms – more than 160 wind turbines are now equipped with ADLS from Lanthan Safe Sky. The technology ensures that the obstacle lights on the turbines are only activated when an aircraft is actually detected, thereby significantly reducing nighttime light emissions. This benefits not only local residents, but also the surrounding environment.

Ventolines was also actively involved as project manager on behalf of the wind farms and coordinated the technical integration. During operation, Ventolines will monitor the system as asset manager of two of the wind farms.

“With our experience from over 6,000 equipped wind turbines and the excellent cooperation with the operators involved and the project developer Ventolines, we were able to successfully complete this challenging project on schedule,” explains Julian Bialk, Business Development Manager at LSS. “The successful activation shows how cross-border cooperation is further advancing the energy transition in Europe.”


About Lanthan Safe Sky GmbH

Lanthan Safe Sky GmbH's mission is to make the skies safer and nights darker. It was formed by the founders and key players of Lanthan, Air Avionics, and RECASE, thus combining 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.

Years ago, the companies involved joined forces to bring safe, cost-effective, and sustainable detection technologies to market with the ADLS transponder.

Intensive work was carried out over a long period of time to gain acceptance for this young technology. This has been successful, as a broad consensus has been 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 ADLS transponder technology, which is emission-free and based purely on the reception of data that every aircraft transmits anyway.
