The electricity production costs take into account the investment, operating and financing costs as well as the wind power generated over the entire project period. In this way, they reflect the costs and revenues of the entire life cycle. The yields depend to a large extent on the wind conditions at the site. For projects implemented in 2016 / 17, Deutsche Wind Guard specifies a cost range of 9.6 ct / kWh for weak locations and up to 5.3 ct / kWh for a location quality of 150 percent.
