The energy production of wind farms depends on local wind resources and the energy production capacity of the wind turbines used. Broadly speaking, they are divided into IEC Category I, Category II and Category III wind farms. Wind farms have the best resources, but in China, most of them are category II and category three wind farms.
At present, traditional wind turbines exceed the megawatt level, and the power curves of imported and domestic wind turbines are not much different. Where availability is guaranteed, the full load equivalent hours per year should. be The average is around 2,000 hours.
In this way, the annual energy production of a most common 1.5 MW wind turbine is calculated as follows: 1,500 kW x 2,000 hours = 3,000,000 degrees = 3 million degrees.
