Prenzlau – Dark Sky GmbH and Enertrag Systemtechnik GmbH have completed the first phase of a project to equip wind farms in the Dutch province of Limburg with demand-based aircraft detection lighting systems (ADLS). Two wind farms have already been fitted with the systems, with further installations scheduled over the coming weeks.

According to the two companies, the expansion reflects growing demand for ADLS systems for wind turbines in the Netherlands and forms part of the international growth strategy of the two Prenzlau-based firms.

The ADLS technology activates the obstruction lighting on wind turbines only when an aircraft approaches, remaining switched off for most of the operating time otherwise. This reduces nighttime light emissions without compromising aviation safety requirements.

The companies said the project builds on ADLS installations already completed in the northern Netherlands. Enertrag Systemtechnik GmbH develops and manufactures the lighting systems, while Dark Sky GmbH is responsible for the regulatory framework covering approval, integration, operation, and service.

"With the successful project in Limburg, we are consistently pursuing our international growth strategy. The Netherlands is a strategically important market for us," said Andreas Jurchen, Head of Sales at Dark Sky and Enertrag Systemtechnik.
