DONG Energy's offshore wind turbines break records


Capacity Factor:
The ratio between actual energy output in a year to the theoretical maximum energy output (100%) is called the capacity factor.

The time when the turbine is operating divided by the total time when it ought to be producing power. Different time periods can be subtracted ie service time.

If a 3 MW turbines produces 12 million kWh annually, the capacity factor will be:
12000000 / (365*24*3000kW) = 12000000 / 26280000 = 0,457 = 45.7 per cent.

A typical Danish household uses approximately 4000 kWh a year. The same 3 MW turbine would then be able to supply: (12000000 / 4000 = 3000) 3000 Danish households with electricity.
