Electricity output
from individual turbine farms can vary greatly (colored lines), but linking them up along whole coastlines can smooth out total power production (thick black line).
The Google - Earth image at the right shows the locations
of individual turbines and a number of the access roads.
The CCSM EIS described the impacts of 1,000 wind turbines and described a NEPA framework for how the project would be authorized but did not identify
individual turbine locations.
It is impossible to predict the amplitude and frequency of transient loads
on individual turbines; farm - to - farm variation can be significant.
As of the start of 2018, 295 wind farms, comprised of 6,415
individual turbines, are operating in Canada.
Offshore wind farms in particular are, at best, going to last twelve years (
individual turbines will fail after about five years).
The authors couldn't determine whether birds that entered a wind turbine field actually avoided coming close to
individual turbines.
2015 was a particularly auspicious year for OSW in Europe, and saw the net addition of 3.0 GW of capacity generated by 754
individual turbines (Ho et al. 2016).
In such farms,
the individual turbines have to be spaced far apart so they don't interfere aerodynamically with neighboring turbines, with the result that «much of the wind energy that enters a wind - farm is never tapped,» says Dabiri.
Arrays of wind turbines and other components including foundations, towers, underground cables (used to collect the power from
the individual turbines), step - up transformers, and switchgear connected through a single point to the transmission grid; group of wind turbines interconnected to a common utility system
The number of turbines used in the calculation is to allow for the fact that as one gets further away from
an individual turbine there are more turbines at a similar distance to the nearest one.
