Alta XI wind farm is situated in California, USA. It was brought online in 2013 and is owned by NRG Yield.
It is near Mojave County.
See below for data.
Typically, economic wind turbines require a wind speed of 4.5 m/s (16 km/h) or bigger.
The best location for something similar to Alta XI would be a steady availability of non-turbulent wind. An essential aspect of turbine siting is furthermore access to local requirement or transmission capaMojave County.
During the planning stages the Alta XI wind farm would’ve been checked and authenticated through wind measurements. Meteorological wind data alone is usually not ample for accurate siting of a large wind power project.
Collection of site-specific data for wind speed and direction could have been vital to determining site potential in order to fund the project. Local winds are frequently watched for a year or more, and detailed wind maps constructed before wind generators are set up.
The wind hits quicker at higher altitudes because of the reduced influence of drag. The surge in velocity with altitude is most dramatic close to the surface and is affected by geography, surface roughness, and upwind obstructions such as trees or buildings. Velocity grows with altitude and it is more pronounced near land and is changed by topography, surface and obstacles.
Wind speeds escalating with altitude is part of a wind energy law. This predicts wind speed rises with the 7th root of altitude. Increasing the height of a turbine, then, increases the predicted wind speeds by 10%, and the predicted power by 34%.
In general, a range of 7D (7 × Rotor Diameter of the Wind Turbine) is defined between each turbine in a fully developed wind farm. But this may not be the case in hilly areas.
Alta XI turbines are related via medium voltage lines and communications.
At a substation, this medium-voltage electric energy is improved in voltage using a transformer for connection to the high voltage transmission system. Building of a land-based wind farm requires installing of the collector system and substation, and possibly access roads to every turbine site.
