Vestas InteliLight® Active Aviation Light Management Benefits of Vestas InteliLight®: • Proven system based on over 10 years of operational experience. • Efficient solution tailored to wind park application. • Aviation lights activate only when needed, avoiding uneccessary, continuous lighting. • Aviation lights remain off 98 % of the time depending on aircraft activity. • Available across turbine brands and multibrand parks. Vestas InteliLight® delivers reliable activation of the aviation lights when needed, while avoiding unnecessary continuous lighting. It is a proven end-to-end solution, designed by Vestas and optimised specifically for wind power plant application. The result is an effective and safe solution available across turbine brands and multibrand parks, compliant with highly restrictive requirements, such as those of DFS/BMVI in Germany. Proven Solution For Vestas InteliLight®, the priority of the system design and function is reliable performance. The first system was installed in 2007 and has been continuously optimised based on more than 10 years of operational experience. Today, more than 1 GW* of turbines operate with Vestas InteliLight®. The system works autonomously onsite, while continuous remote monitoring verifies system integrity. A secondary power backup and fail-safe mode ensure operational readiness. System Integration Vestas InteliLight® is directly connected with the turbine aviation lights through the Vestas communication network, enabling prompt and reliable reaction when needed. For non-Vestas turbines, the turn-key system is directly connected to the turbine aviation lights, working independently of the windpark control system. * Based on installed capacity by the end of September 2019.

Aviation lights activate when needed: One Vestas InteliLight® radar may cover several wind parks*, yet the system only activates lights in the relevant parks. In this case, aviation lights are activated in the blue and purple wind parks, but remain off in the orange wind park. Siting In the case of Vestas wind park planning, the Vestas InteliLight® application is considered in the regular Vestas turbine siting process. For existing Vestas, non-Vestas and multibrand wind park application, a coverage assessment is prepared by dedicated InteliLight® personnel. Specialised siting tools using topographical...
