The short answer scaling heavily favors huge turbines. The taller they are the larger swept area of the blades. More are more wind energy captured. (Good old area = distance squared) And higher up the more consistent the wind, higher the average wind speed, and thus higher capacity factor.
- kumarvvr 5y agoRecently read in an article about turbine scaling, that an 18% increase in blade length translates into 45% increase in power output. Scaling is extremely lucrative. And break even for these turbines is aroun 5 to 8 years, with active life of around 30.
