How To Calculate The Annual Energy Output From A Wind Turbine
Take the case of a 600 kW turbine that generates 1.5 MWH annually; the capacity factor would be = 1500000: (365.25 * 24 * 600) = 1500000; 5259600 = 0.285 = 28.5 percent. Although capacity factors might theoretically range from 0% to 100%, in reality they are more likely to be in the 20%–70% range, with the majority falling in the 25%–30% area.

This is the maximum power output that the wind turbine can achieve under ideal conditions. The capacity factor is then calculated using the formula: Capacity Factor = (Annual Energy Yield / (Rated Capacity * 8760)) * 100. The calculation takes into account that there are 8760 hours in a year (365 days x 24 hours/day).
Optimal siting and sizing of wind farms
From an investor''s point of view, the first important criterion to decide on the location of a wind power plant is the promise of strong wind. The main parameters that capture the wind power potential at a site are the average wind speed, the theoretical wind power density and the capacity factor of a prospective wind turbine [10]. 3.1.1.

The net capacity factor is the unitless ratio of actual electrical energy output over a given period of time to the theoretical maximum electrical energy output over that period. The theoretical maximum energy output of a given installation is defined as that due to its continuous operation at full nameplate capacity over the relevant period. The capacity factor can be calculated for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy

Although geographical location determines in great part the capacity factor of a wind farm, it is also a matter of turbine design. Indeed, a large rotor combined
Performance and Reliability of Wind Turbines: A Review
2.1. Capacity Factor An easy and commonly used indicator to describe the performance of a WT is the capacity factor (CF), which is the ratio of the turbines actual power output over a period of time to its theoretical (rated) power output [8,9]. For the calculation of the capacity factor the average power output is
Capacity Factor
The capacity factor is a very significant index of productivity of a wind turbine. It is the ratio of the actual energy produced in a given period, to the hypothetical maximum possible, i.e. running full time at rated power. In this paper, the capacity factor is calculated by the following expression: (33) where.
