Senvion is launching what it calls the company’s highest-yield onshore wind turbine for the North American market: the Senvion 3.4M140.
Available in 2018, the new tower will be available in hub heights of 110 and 130 meters. The 68-meter blades at these tower heights alone permit high yields at low-wind locations such as forested and mountainous areas, explains Senvion. In addition, the blade profile offers integrated serrations to reduce noise, which makes the unit ideal for sites with sound restrictions.
Compared with the 3.0M122, the 3.4M140 generates up to 20% greater yields, depending on the location, says Senvion, adding that the service life of the turbine is extended to 25 years. The tower is also managed by a new pitch control system to reduce turbine load.
The Senvion 3.4M140 was first announced for the 50 Hz market this past September at Husum Fair; the company is now launching the adapted version for the 60 Hz market at this week’s WINDPOWER 2016.
“Developments such as serrations are a big step forward and even allow larger turbines to adapt to market requirements,” explains Bernhard Telgmann, executive vice president for product and technology at Senvion. “Despite its size, the Senvion 3.4M140 will be one of the quietest turbines on the market, and we will continue to optimize this technology.”
Helmut Herold, CEO of Senvion for North America, adds, “By offering the Senvion 3.4M140, with longer rotor blades that can be operated even more profitably and cost-efficiently at great heights, Senvion is offering a solution to make low-wind locations more profitable.”
