Wind turbines

Senvion uses the latest technology to help customers take advantage of the opportunities in wind energy, one of the fastest growing and leading sources of new electricity around the world. With our versatile portfolio we have the right wind energy solutions for your specific project needs.

Our mission is to make wind energy highly competitive, affordable and in service of the communities where we operate. We’re continuously strengthening our position as a leading and growing wind energy player in North America.

3.7M144 EBC: Senvion extends modularity of its 3.XM turbines in North America

The new Senvion 3.7M144 EBC is a low wind specialist. With its bigger rotor, a rated power of 3,700 kW and new, highly efficient rotor blades it can achieve a 6.7% higher annual energy production (AEP). The new rotor blades – also used with the 3.4M140 and 3.6M140 – are based on the new Rodpack technology which replaces standard glass fibre fabric in the blade’s main girder. Rodpack technology is used exclusively in Senvion rotor blades and delivers significant improvements in material properties. Last but not least, the aerodynamically optimized blade design and the use of serrations on the trailing edge make the new Senvion 3.7M144 EBC one of the quietest turbines for low wind speeds on the market.

  • Nominal power: 3,700 kW
  • Rotor diameter: 144 m
  • Hub height: 108 - 165 m / project specific
  • Nominal frequency: 60Hz
  • Wind class: Low Wind
  • Operating temperature range: -30 – +40 °C (with cold climate option)
  • Rotor surface: 16,286 m²

Grid Integration

As demand for alternative energy grows, wind farms are under pressure to function in the same way as a conventional power plant, which includes better integration into the grid.

Senvion is responding to this challenge with wind turbines that actively support the grid, fulfilling and surpassing the necessary requirements and ensuring reliable energy supply, even during a breakdown.

The key to our success is the proven concept of a gear and a twin-fed asynchronous generator, combined with innovative control functions. In any operating mode, Senvion turbines feed controlled reactive power into the grid. This enables constant voltage control, which maintains the line voltage. Even during temporary voltage dips, our wind turbines stay connected and help to keep the grid stable. If there are any frequency fluctuations, the power from our turbines is automatically adjusted, based on needs.

With Senvion technology, grid integration is no longer a worry. We connect our wind turbines to the grid – and stabilize it.

Icing Solutions

Our proven de-icing technology is built to withstand whatever winter brings, giving you warm feelings about your Annual Energy Production (AEP) for up to 25 years.

Many of our turbines in North America include a specialized de-icing system. That said, de-icing is not necessarily the best and one and only solution for colder climates. That’s why Senvion has developed a solution for colder climates, taking into consideration all of the health and safety implications, particularly around public roads and in urban settings. 

We separate wind farms into two risk categories: Category 1 is where turbines can continue operating under icing conditions without any risk, usually in rural settings; Category 2 includes areas close to public roads and/or urban dwellings where turbines must be shut down as soon as an icing risk is detected. Sometimes it is more effective to operate a windfarm according to this model than using a de-icing solution.
