Wind Energy Calculators
Last updated: September 2026
Wind Energy Payback Period Calculator
Calculate how many years it takes to recover your net wind energy investment from annual savings minus maintenance costs.
Wind Turbine Annual Energy Calculator
Estimate a turbine or wind farm's annual energy production from its rated capacity and the expected capacity factor.
Wind Turbine ROI and Payback Calculator
Determine the payback period and return on investment for a wind turbine project by inputting installation cost, annual generation, electricity price, O&M costs, and any government incentives.
Small Wind Turbine Sizing Calculator
Estimate the rated power capacity (kW) of a small wind turbine needed to meet a household or business's energy demand.
Wind Farm Annual Energy Yield Calculator
Calculates the gross annual energy production (AEP) of a wind farm given fleet size, turbine capacity, capacity factor, and availability.
Wind Energy Capacity Factor Calculator
Estimates a wind turbine's capacity factor — the ratio of actual output to maximum possible output — and annual energy yield.
Wind Farm Annual Energy Production Calculator
Estimate how much electricity a wind farm will generate per year by entering turbine count, rated power, capacity factor, availability, and wake losses.
Wind Turbine Sizing Calculator
Find the minimum rated power needed for a wind turbine to meet your annual energy demand, given a site's expected capacity factor and system efficiency.
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.
Wind Farm Turbine Spacing Calculator
Calculate the hub-to-hub distance from a turbine to its diagonal neighbour in a row-and-column wind farm layout, from the rotor diameter and the downwind and crosswind spacing factors.
Wind Turbine Structural Load Calculator
Calculate the design thrust force (in kN) acting on a wind turbine rotor under extreme wind conditions, accounting for rotor swept area, air density, design wind speed, and turbulence.
Wind Turbine Noise Level Calculator
Calculates the sound pressure level at a receiver location downwind of a single wind turbine, accounting for distance, terrain, and atmospheric attenuation.
Wind Turbine Tip Speed Ratio Calculator
Calculate the tip speed ratio (TSR) of a wind turbine — the ratio of blade tip velocity to incoming wind speed.
Wind Load on Turbine Calculator
Calculates the total quasi-static wind force acting on a wind turbine tower for structural engineering checks.
Wind Speed Frequency Distribution Calculator
Compute the Weibull probability distribution of wind speeds at turbine hub height to estimate how many hours per year a site experiences any given wind speed.
Wind Shear Profile Calculator
Estimate wind speed at any height using the power law or logarithmic model.
