Important factors for the developments in wind turbine technologies are size of rotor diameter and hub height. Recently, various developments in technology have taken place to manufacture larger‐capacity turbines. These advances have increased the efficiency along with reduction in capital and operation costs. Large rotors increase the capacity of wind turbines even in low wind areas. By 2018, rotor diameter has increased to 110.4 m with wind turbine ratings of 2.6 MW from rotor diameter of 50.17 m with 1.0 MW capacity of wind turbine in 2000 (Pérez‐Collazo et al. 2015; IRENA 2019d; www.windpowermonthly.com). Expected capacity of the wind turbine by 2022–2025 is 5.8 MW with rotor diameter equal to 170 m. In a particular example, GE has come up with improved onshore turbine technologies rated at 4.8 MW and 5.3 MW, respectively (www.windpowermonthly.com).
