The ratio between the total electricity production of a wind farm during a certain period divided by the product of the number of hours during that period and the installed capacity of the power plant. (Expressed as a percentage)
Taking a certain month as an example, a generator set with a gross capacity of 300 MW generates 120 million kilowatt hours, has an operating time of 436 hours and the monthly statistical duration is 720 hours, then The equivalent operating hours in gross capacity are:
(12000÷436)/30×436=400 (hours)
The gross capacity coefficient is:
400/720*100=55.56
The ratio between the hours of annual effective use of the wind farm and the number of hours throughout the year, or the relationship between the actual annual network of the wind farm. electricity connected to the nominal annual electricity connected to the grid. (Expressed as a percentage)
