Annual Wind Energy Yield Calculator
Estimate the annual energy production and revenue from a wind turbine installation
About this calculator
The Annual Wind Energy Yield Calculator helps property owners, developers, and energy investors estimate the yearly electricity production and potential revenue from wind turbine installations. By analyzing factors like wind speed, turbine specifications, and local energy prices, this tool provides crucial insights for evaluating wind energy project feasibility. Understanding annual energy yield is essential for calculating return on investment, securing financing, and making informed decisions about wind power installations.
How to use
Enter your location's average wind speed, select or specify your wind turbine model with its power rating and cut-in speed, then input local electricity rates or feed-in tariff prices. The calculator will estimate annual kilowatt-hours produced and potential revenue based on your inputs and typical wind patterns.
Frequently asked questions
What wind speed data should I use for accurate calculations?
Use annual average wind speeds measured at hub height (typically 80-120 meters). Local weather stations or wind resource maps provide this data.
How does turbine size affect annual energy production?
Larger turbines with higher capacity factors generally produce more energy annually, but actual output depends on local wind conditions and turbine efficiency curves.
What factors can reduce actual energy yield from calculated estimates?
Maintenance downtime, grid curtailment, wake effects from nearby turbines, and seasonal wind variations can reduce actual production below theoretical calculations.
