Windtest Grevenbroich
Independent Design & Yield Assessment
Windtest has spent about 30 years providing independent testing and engineering for renewable-energy projects. It is based in Grevenbroich, Germany, and has had a North American subsidiary since 2014. It is accredited to DIN EN ISO/IEC 17025:2018, is a recognised IECRE measuring laboratory and is a full MEASNET member.
What windtest brings to your project:
- Wind potential measurement using remote sensing
- (LiDAR/SoDAR) or met masts
- Energy yield assessment and reference yield calculation
- Site quality assessment to TR 6 and TR 10
- Power performance testing and model validation after commissioning
- Power quality, harmonics and grid-compliance testing for turbines and energy storage
- Noise and shadow-flicker prognosis for permitting.
Grevenbroich Test Site
To accelerate the energy transition, renewable energy technology must be used efficiently. Our test site in Grevenbroich Germany offers unique conditions to test and optimize renewable energy technology under real conditions. This helps to reduce CO2 emissions.

Wind Technik Nord
Turbine Supply & Installation
Wind Technik Nord GmbH was founded in 1986 in Enge-Sande, North Friesland, Germany. It develops, builds and sells wind turbines and is DIN ISO 9001:2015 certified, with its processes regularly reviewed by DNV.
Turbine range:
- WTN 250: developed for export markets outside Europe, built on proven technology for high availability
- WTN 600: 600 kW, 46 m or 48 m rotor, variable speed and pitch control
- WTN 200/26: type-certified, available fully refurbished as a lower-cost option
- Wind-driven water pumps: simple, long-life and low-maintenance, for water supply on remote sites
Services: assembly and installation, climbing aids and accessories, maintenance, operator training, and turbines in other sizes under licence or joint venture.
How we work
A practical approach from concept through implementation and ongoing support.

Operation

Energy Yield Assessment
How much energy can a wind energy project actually generate at a specific location?
We visit the site and review your loads and existing generation. Then measure the wind resource with LiDAR, SoDAR or a met mast.

System Design
windtest provides an independent energy yield assessment.
ThinxEnergy sizes the wind, PV and battery mix and the grid-forming control strategy, then selects a suitable Wind Technik Nord turbine..

System Integration
Wind Technik Nord supplies and installs the turbines. ThinxEnergy integrates them with your battery, PV, diesel and energy management systems.

Monitoring & Support
We verify power performance after commissioning. ThinxEnergy monitors the system continuously, and Wind Technik Nord provides service and training for local staff.
