Chemé wind project was installed in Pays de la Loire, France It was brought online in 2009 and is owned by .
It is near .
See below for data.
As a rule, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or higher.
The very best location for something like Chemé is a steady availability of non-turbulent wind. An important factor of turbine siting is furthermore admission to local requirement or transmission capa.
Before development, Chemé was most likely screened on the foundation of a wind atlas, and validated with wind measurements. Meteorological wind data alone is usually not enough for precise siting of a large wind power project.
Site info around is a major factor in the ‘development’ final decision Local winds are often watched for a year or more, and comprehensive wind maps built before wind generators are set up.
The wind hits quicker at higher altitudes due to the reduced effect of drag. The rise in velocity with altitude is most spectacular close to the surface and is impacted by topography, surface roughness, and upwind hurdles such as trees or buildings. Velocity grows with altitude and is also more pronounced near land and is transformed by geography, surface and obstructions.
Wind speeds growing with altitude is part of a wind energy law. This anticipates wind speed rises with the 7th root of altitude. Doubling the height of a turbine, then, increases the expected wind speeds by 10%, and the predicted power by 34%.
In general, a length of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. But micrositing increases placement, specially in hilly areas.
Chemé turbines are connected via medium voltage lines and communications.
At a substation, it medium-voltage electric energy is increased in voltage using a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installation of the collector system and substation, and probably roads to each turbine site.
