The latest 15MW wind turbine model from leading global producers can generate approximately 80 GWh each year. In comparison, 1 GWh is the average amount of electricity used by 5o detached houses during one year. During its expected life span of 30 years, a turbine is able to produce a total of 2400 GWh. The exact realized production capacity depends of course on the location of and wind conditions at the production site.
Turbines are seldom dismantled precisely after 30 years and often stand for a longer time. A cautious estimate based on current technology renders a life span production capacity of 2500 GWh.
