More energy for our future

VENSYS offers gearless wind turbines for all wind classes and locations.


26,800 wind turbines using VENSYS technology worldwide with 50 GW total rated capacity on the grid.

VENSYS ENERGY develops and manufactures gearless wind turbines with high efficiency for maximum yield. Our trademarks are powerful turbines with a permanent-magnet-excited multipole generator, a maintenance-free toothed belt drive for rotor blade adjustment, simple generator cooling and the full converter system with power generating characteristics.

Our 1.5 MW to 5S platforms consist of only a few high-quality and durable components. The simple, compact design, low maintenance costs and the advantages of wear-free systems already ensure increased yield thanks to their design.

Customer-tailored wind turbines are developed in an individualised project development – including for small wind farms and the integration of local interests at a community scale, as well as tailor-made supply solutions for companies.
VENSYS provides municipalities and investors with comprehensive, worry-free solutions, from planning tailored to individual cases, to installation and grid connection, to an attractive service package with guaranteed availability for the entire service life.

Production in small series also gives us the flexibility for individual adaptations. Based around the manufacturing concept, our own production at our headquarters in Germany forms the basis for the permanent transfer of developments into VENSYS products. Innovative technologies go hand in hand with solid workmanship, complex quality management and needs-driven short delivery times.

Together with our subsidiaries, we offer an individually scalable complete range of services. The coordinated further development of central turbine components guarantees seamless functionality and higher added value across the entire supply chain and the lifecycle of the turbines.
The VENSYS Group's range of services includes full-scale converters and pitch systems, electronic components and network connections as well as network planning, network integration and certification of the turbines. New to the VENSYS Group is in-house manufacturing and continued development of rotor blades.

Reliable and profitable at any location. Proven in endurance tests on four continents.

Wind turbines from our German production facilities are connected to the grid in Germany, Poland, France, Great Britain, Spain, Cyprus, USA and Canada. Further markets are being explored, supported by our subsidiary in Poland and VENSYS Inc. in the USA.

As the driving force for advanced wind power generation, VENSYS exports its technology worldwide. Our successful licensing model combines innovative technology and "made in Germany" know-how with series production, market development and logistics in an internationally operating business network. VENSYS is therefore in a position to implement its own large-scale projects everywhere.

Our most important licensees, Goldwind and ReGen Powertech, manufacture VENSYS turbines as high-growth multipliers for India, China, Asia, USA, South America, Australia and Africa. 
VENSYS wind energy technology has proven itself on four continents: under a wide variety of climatic conditions, under all network conditions, even in regions with poor infrastructure. Supported by regionally adapted service and customer-orientated support, more than 26,800 turbines with 50 GW are connected to the grid.

Building on the expertise of nearly three decades of innovative engineering, we are already working on pioneering solutions for cold-climate and hybrid turbines.
