A study of wind measurements and infrastructure has revealed two sites "eminently suitable" for wind development in the Canton of Vaud, reports wind project developer Interwind of Zurich. Planning will go ahead for three turbines at La Gite Dessus and four turbines at Le Mont de Cerfas. Average generation costs for the projects over 20 years are calculated at CHF 0.14-0.16/kWh (i0.09-0.10). Average winds over four years have been measured at 5 m/s at a height of 40 metres, and up to 6.5 m/s at 67 metres. Interwind has used 1.65 MW turbines -- the largest commercially available -- for project visualisation. "We wanted to make sure that the largest could be used, if necessary, as the area is limited and the larger the turbines the more economic the project will be," says the company. The environmental impact of the projects has been found acceptable by canton authorities and Pronatura, a non governmental organisation. Interwind is now in the process of putting together a siting application, as well as founding an operating company to co-ordinate finance, planning and construction of the projects. Completion is not expected before next year at the earliest. The study was required by the municipality of St Croix to show the feasibility of wind development in the area, with financing from Vaud and the Bundesamt für Energie, the federal energy office.
