The new MM100 wind turbine, introduced at November’s CanWEA Canadian wind energy trade fair, has been developed for the North American wind market and will be available in a 60-Hz version with an 80-m tower height and a 1.8 MW rating. The turbine, from REpower in Germany, is for use in areas with low wind speeds. The 100-m rotor, about 18m more than other turbines, will assist in energy capture. New LM 48.9P Evolution rotor blades, developed jointly by LM Glasfiber and REpower, are used on the MM100. The turbine’s power cabling, conductor rails, and converter are modified for best grid properties in comparison with the other models in the series. The first pilot turbines are scheduled for installation as early as the end of 2011. Series production of the MM100 is set for mid-2012.
The turbine’s high net-capacity factor is of interest to owners. Locations with limited network feed-in capacity are common in the U.S. In these cases, it is better if the turbine achieves rated power quickly and thus makes the best possible use of the defined installation power.
REpower Systems has produced the MM series since 2002, starting with the MM70 with a 70-m rotor. The following year, the Hamburg-based wind turbine manufacturer launched its MM82 turbine with an 82-meter diameter. Following in 2005 was the MM92, a variant with a larger rotor, which is already at work on many American wind farms, along with a cold climate version in Canada. REpower CTO Matthias Schubert says: “When developing the MM100, we were able to build on our experience with over 1,700 MM-series turbines installed across the world. The turbine is based on the same reliable and maintenance-friendly concept as its predecessors.”
