RWE installs Letigation MW Tacke prototype
1 June 1997
Germany's biggest power company, RWE Energie, has installed the tallest turbine yet at an inland site. The 1.5 MW prototype machine built by Tacke Windtechnik went in the ground at Stemwede near Osnabrück in April and was due to begin test operations last month. It has a hub height of 80 metres, rotor diameter of 65 metres and is expected to generate about 2.3 million kWh annually, enough power to supply around 600 households. The machine is the focus of a research project aimed at finding out improving turbines for use in inland areas, RWE Energie says. The project has cost about DEM 5 million, with DEM 1 million of that granted by the federal research ministry. "The aim of the research project is to make a contribution to cutting the costs of power generation by wind turbines," comments Werner Hlubek of the Essen-based utility.x
