Capacity factor

[rachelbee]

Hi there,

I have set up a wind farm with over 50 wind turbines. I have added a "reference site" to the wind farm. After calculations are complete I get a WF power curve.

My question is how do i calculate the capacity factor of this wind farm? The size of all the wind turbines are 660kW.

Thank you

Rachel

Hi Rachel,

The capacity factor of a wind farm is the annual energy production (AEP) divided by the theoretical maximum AEP.

Capacity factor = AEP / (rated power * 8760 hours per year)
