Throughout the history of the development of wind power industry one could observe the ongoing commitment of wind turbine manufacturers to create larger wind turbines, capable of providing a maximum installed capacity of the unit.
As it is well-known, the unit capacity of wind turbine today is up to 8 MW and generators with capacity of 10+ MW are being developed.
If we consider the sea-based wind turbines (offshore), there is probably a potential for growth. However, the industrial giants have already established the most effective balance of power and performance.
According to the statistics published by the European Wind Energy Association (EWEA) in February 2016, the manufacturers of offshore wind turbines in 2015 focused precisely on the turbines in the range of 4 - 6 MW.
Regular statements by various experts about the imminent passage of wind power to 10-megawatt (and more) wind turbines, were refuted at the EWEA exhibition last November. Commenting on their development strategies in the near future, industry leaders speak about the greatest cost-effectiveness of the generators at an altitude of 100 - 150 m with the installed unit capacity of around 3 MW for land-based, and 5-7 MW for sea-based.
