This calculator applies the power law to estimate how raising a turbine on a taller tower affects wind speed and consequently power output. By quantifying these effects, users can decide whether investing in additional
A feature of the propellor anemometer that has been noted by EAS students when calibrating propellor and cup anemometers side-by-side in the wind tunnel, is the much faster rotation rate of the propellor.
Check the performance data of our and other small wind turbines and simulate different constellations of rotor area, wind speed and efficiency.
It is evident from this figure that as the height of wind measurements increases the wind speed range decreases. At 40m AGL, the half hourly mean wind speed varied from 4.7m/s to 7.0m/s
The following are calculations for power available in the wind at three different velocities for the Northwind 100C turbine. This is the newer version of the Northwind 100A on the previous page.
A complete guide to calculating the power output of wind turbines. Explore formulas, wind speed effects, rotor area, and practical steps for energy estimation.

A: The terrain category affects the wind speed at a given height because it determines the value of the power law exponent alpha. Different terrain categories have different values of alpha, which means that
The anemometer, most commonly used in wind energy measurements is the cup anemometer. It consists of three (or four) equally spaced cups attached to a centrally rotating vertical axis through spokes (Fig. 1).
Definition: This calculator estimates wind speed at a target height based on known wind speed at a reference height and the wind shear exponent. Purpose: It helps meteorologists, engineers, and energy professionals
