Wind Farm Annual Energy Production Calculator
Calculate annual energy production and capacity factor for wind farms based on turbine specifications and wind conditions
About this calculator
The Wind Farm Annual Energy Production Calculator helps renewable energy developers, investors, and engineers estimate the yearly electricity output and efficiency of wind farm projects. By inputting turbine specifications like rated capacity, hub height, and rotor diameter along with local wind conditions including average wind speed and air density, users can calculate key performance metrics including annual energy production in MWh and capacity factor percentages. This tool is essential for feasibility studies, financial modeling, and optimizing wind farm design to maximize energy yield and return on investment.
How to use
Enter your wind turbine specifications including rated capacity, hub height, and rotor diameter. Input local wind conditions such as average annual wind speed and air density for your site location. The calculator will instantly compute your wind farm's expected annual energy production in megawatt-hours and capacity factor percentage.
Frequently asked questions
What is capacity factor in wind energy?
Capacity factor is the ratio of actual energy output to maximum possible output, typically ranging from 25-45% for wind farms depending on wind conditions.
How does hub height affect energy production?
Higher hub heights access stronger, more consistent winds, typically increasing energy production by 5-15% for every 10-20 meter height increase.
What wind speed is optimal for wind turbines?
Most turbines operate optimally at 12-15 m/s wind speeds, with cut-in around 3-4 m/s and cut-out at 20-25 m/s for safety.
