Nordex Balcke-Dürr says it will install a prototype 1.25 MW machine at "a site in Germany" in September and is also working on a 2.5 MW design for the future. The company made the announcement last month at the Renergie 97 conference in Hamm, North Rhine Westfalia (NRW). The 2.5 MW unit would have rotor diameter of 80 metres, according to Nordex Vetrieb, the German marketing arm of Nordex Balcke-Dürr. The company also revealed that it may start production of its 1 MW N54 turbine in North Rhine Westfalia soon, to supplement the assembly works at Rerik in Mecklenburg Vorpommern. The company expects a series of orders in the coming winter months and, assuming all goes well, will need to step up production fast. Assembly in NRW at the Balcke-Dürr headquarters in Ratingen is one option, the other being a pre-assembly station in east German Saxony or Saxony Anhalt, where components manufactured locally can be put together before being sent to Rerik for final assembly. The company is looking to celebrate installation of the fiftieth Nordex N54 before the autumn.
