Personal understanding: 1. Wind power generation uncertainty refers to the uncertainty of the wind power utilization rate of the wind farm throughout the year. The time spent on normal maintenance and shutdown of wind turbines is uncertain each year, so the duration of wind energy use of wind turbines throughout the year is uncertain and the amount of electricity produced is uncertain.
2. When selecting a location for a wind power plant, select the location where the wind turbine will be erected. After at least two to four years of accumulating crosswind data in the selected area, use the wind turbine site. selection software to make the selection. After the selection, the wind farm will be completed for at least It will take another two years. During this period, environmental change factors cannot be predicted, so it is also the uncertainty of thehe production of wind energy.

15,000 yuan-17,000 yuan/kw.
According to data compiled by the National Energy Administration and the China Commercial Industry Research Institute, the construction cost of offshore wind power is about 15,000 to 17,000 yuan/kw, of which the price of offshore wind turbines is around 6,000-7,000 yuan/kw. Between 2010 and 2022, the global weighted average total installed cost fell by 34%, from $5,217/kW to $3,461/kW.
