REpower Systems of Germany has put development of its planned 3 MW machine on the backburner. Instead it will concentrate on a 2 MW onshore machine and a 5 MW turbine, mainly for offshore use. The prototype of the REpower MM82 2 MW, which the company says features a "significantly larger rotor diameter of 82 metres," is to be installed in the spring. A 60 Hz version of the machine as well a 60 Hz version of its MD70 1.5 MW turbine are being developed for the Japanese and American markets. Explaining its decision the company suggests the 3 MW turbines would have been used only as an intermediate solution offshore until larger machines were ready and to fill a niche for particular onshore locations in Germany. REpower's Matthias Schubert says REpower will "adequately fill this niche with its 5 MW unit, especially as it will be delivered at the same specific price as the projected 3 MW turbine." He adds that the 2 MW machine will have a "significantly lower" price tag per installed megawatt than the originally planned 3 MW turbine, making it "extremely competitive."
