Wind Turbine Power Output Calculator

Estimate the electrical power a wind turbine produces from its rotor diameter, the wind speed, and its overall efficiency. Use it for early-stage siting decisions and to compare turbine models before going to full energy-yield software.

Wind Energy

Wind Speed Height Adjustment Calculator

Convert a wind speed measured at one height to the equivalent wind speed at a different height using the power-law (Hellmann) model. Essential for projecting met-mast or weather-station readings up to turbine hub height.
