Suzlon Group, the world’s fifth largest wind turbine maker, has expanded its REpower 3.XM series. The group’s subsidiary REpower Systems SE is presenting the restructured portfolio at HUSUM WindEnergy 2012 trade fair. In line with their potential, the existing turbines from the 3-megawatt class - the REpower 3.2M114 and REpower 3.4M104 - are being certified for use at sites with higher wind speeds.

A third turbine type, the 3.0M122, has been added to the company’s 3.XM series. It has been specially designed for conditions at sites where there is lower wind. The first variant of the new turbine with a hub height of up to 139 metres will be on sale starting in early 2013, a prototype erected in the fourth quarter of 2013. The 3.4M104 is particularly suitable for sites with high winds. It will be available in four hub heights (80 m, 93 m, 100 m, 128 m) for IEC class I (high wind) sites starting in 2014. The 3.2M114 has a rated power of 3.2 megawatts. It will be designed for sites with average wind speeds and will be available in all three hub heights (93 m, 123 m, 143 m) in the corresponding IEC II wind class starting in mid-2013. In addition to certification for IEC classes, the turbines are also being certified for the highest wind zones and terrain categories in accordance with the German DIBt guidelines.

The new REpower 3.0M122 has a rated output of 3 MW and a rotor diameter of 122 metres. With a coated rotor surface of more than 11,600 square metres, it is the largest REpower onshore turbine in terms of its rotor diameter. With the larger rotor combined with the high hub height of 139 metres, the turbine is designed to be even more cost effective at low wind sites.

REpower has sold over 300 turbines from the 3.XM series since its launch. The series is currently offered in 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.
