Test Site Lelystad

Test Site Lelystad – a full service wind turbine testing facility – provides a comprehensive range of facilities for prototype testing, infrastructure, wind measurements and wind turbine testing services. With 10 positions for wind turbine prototyping and certification measurements, and a combined installation power of 30 MW, this is the largest site of its kind in Europe. The testing facilities, which are located at Wageningen University and Research’s location near Lelystad in the Netherlands and which are operated by Ecofys Wind Turbine Testing Services (WTTS), can serve to trial the latest generation turbines with rotor tip heights up to 200 metres. All of the positions at the site are currently occupied, serving seven different international wind turbine manufacturers.

Our services support innovation

Test Site Lelystad provides infrastructure (access roads and a high-speed glass-fibre network), accredited wind measurements, as well as the complete portfolio of wind turbine measurement services – power performance, power quality, sound emission, mechanical loads and grid code certification – which are required for IEC and MEASNET compliant turbine certification. The accredited measurement services are provided by Ecofys in collaboration with windtest grevenbroich gmbh. These services make a major contribution to further innovation in the wind power industry.

Site management and coordination

Ecofys WTTS coordinates all of the activities at Lelystad Test Site. These include a Health, Safety & Environment management system as well as coordinating measurement campaigns, including the use of wind forecasting, all designed to create optimal measurement conditions and  ensure that critical measurements can be performed without causing disturbance. Ecofys WTTS is also responsible for the measurement masts erected near the testing turbines, ranging from 81 to 140 metres.
