The first wind turbine in the Paris region is now operating at Guitrancourt, 60 kilometres northwest of the capital. Vergnet, which specialises in small to medium sized turbines, particularly in France's overseas territories, has installed a single 60 kW turbine at the town's experimental waste treatment plant as part of an energy-efficient management system. The latest project represents the first example of a small turbine connected to the French national grid. According to a wind atlas produced by Espace Eolien Développement (EED) for environment agency ADEME, Guitrancourt lies in one of the windiest locations around Paris; the annual average wind speed at the top of the turbine's 40 meter tower is estimated at 4.63 m/s. Though by no means France's windiest spot, the atlas reveals that the region has sufficient wind resources to be commercially viable.
