Bishop Hill II wind project was installed in Illinois, USA It was in fact brought online in 2012 and is owned by MidAmerican Energy.
It is near near Galva, Henry County.
See below for data.
For the most part, economic wind power generators require a wind speed of 4.5 m/s (16 km/h) or greater.
The best destination for something similar to Bishop Hill II is a steady supply of non-turbulent wind. An essential aspect of turbine siting is furthermore admittance to local demand or transmission capanear Galva, Henry County.
During the planning stages the Bishop Hill II wind farm would have been checked and confirmed through wind measurements. Meteorological wind data alone is usually not sufficient for exact siting of a large wind power project.
Collection of site-specific data for wind speed and direction would have been imperative to determining site potential in order to finance the project. Local winds are often watched for a year or more, and detailed wind maps made before wind generators are set up.
The wind hits quicker at higher altitudes because of the reduced effect of drag. The boost in velocity with altitude is most spectacular near the surface and is affected by landscape, surface roughness, and upwind hurdles such as trees or buildings. Velocity grows with altitude and is more distinct near land and is changed by geography, surface and hurdles.
Wind speeds escalating with altitude is part of a wind energy law. This forecasts wind speed rises with the 7th root of altitude. Increasing the elevation of a turbine, then, enhances the anticipated wind speeds by 10%, and the expected power by 34%.
The distance of 7x Rotor Diameter is placed between each turbine, ie they’re spaced out so they really don’t affect each other. However this might not be the case in hilly areas.
Bishop Hill II turbines are linked via medium voltage lines and communications.
At a substation, that medium-voltage electric current is increased in voltage with a transformer for link with the high voltage transmission system. Development of a land-based wind farm requires installing of the collector system and substation, and probably access roads to each and every turbine site.
