Continued growth of wind turbine physical dimensions is examined in terms of the implications for wind speed, power and shear across the rotor plane. High-resolution simulations with the Weather Research and Forecasting model are used to generate statistics of wind speed profiles for scenarios of current and future wind turbines. The nine-month simulations, focused on the eastern Central Plains, show that the power scales broadly as expected with the increase in rotor diameter (D) and wind speeds at hub-height (H). Increasing wind turbine dimensions from current values (approximatelyH= 100 m,D= 100 m) to those of the new International Energy Agency reference wind turbine (H= 150 m,D= 240 m), the power across the rotor plane increases 7.1 times. The mean domain-wide wind shear exponent (alpha) decreases from 0.21 (H= 100 m,D= 100 m) to 0.19 for the largest wind turbine scenario considered (H= 168 m,D= 248 m) and the frequency of extreme positive shear (alpha> 0.2) declines from 48% to 38% of 10-min periods. Thus, deployment of larger wind turbines potentially yields considerable net benefits for both the wind resource and reductions in fatigue loading related to vertical shear.
