The Suzlon Group, the fifth-largest manufacturer of wind turbines in the world, has announced the launch of its REpower 3.0M122 turbine as a 60-Hz variant for the Canadian market.
REpower Systems SE, a subsidiary within this Group, will be presenting its variant of the 3.0M122 for the Canadian market at the CanWEA trade fair.
The 3.0M122 is the third and most recent turbine type to be added to the company’s 3.XM series since September 2013 and is designed especially for the specific conditions encountered at low-wind locations. The first variant with a hub height of 100 metres will go on sale in Canada in late 201
3. The prototype is to be erected in the first quarter of 2015.
The REpower 3.0M122 has a rated output of 3.0 megawatts and a rotor diameter of 122 metres. Thanks to the larger rotor combined with th
e hub height of 100 metres, use at low-wind sites can be made even more cost effective, thereby helping to reduce energy costs.

Particularly cost-effective in low-wind locations thanks to the large rotor
Andreas Nauen, CEO REpower Systems SE, explains:
“With the REpower 3.0M122, we can achieve optimum energy yield at non-coastal sites with lower wind speeds as well as in challenging areas such as hilly terrain or forests. Particularly in Ontario, many wind farm locations are situated near to built-up areas.
For projects like these, apart from the cost-effectiveness of our turbines, it is also their quietness that makes them so impressive.”
REpower has sold over 300 turbines from the 3.XM series since its launch in 2009. The manufacturer currently offers seven variants. The 3.4M104 is available in four different hub heights, the 3.2M114 in three. Further hub heights are planned for the 3.0M122 aswell.
