Wind Turbine Profit Calculator

A turbine's revenue depends on its output and what you earn per kilowatt-hour.

How the Math Works

The Wind Turbine Profit Calculator uses a straightforward formula to estimate annual revenue: revenue equals power output multiplied by the turbine's capacity factor, then multiplied by 8760 (the number of hours in a year) and the electricity price, divided by 100,000 to convert to appropriate units. The capacity factor represents how often the turbine operates at full power, typically ranging from 20-35% for modern turbines. This calculation assumes consistent electricity pricing and doesn't account for maintenance costs, taxes, or other expenses that would affect actual profit margins.

Practical Applications

To use this calculator effectively, gather three key pieces of information: the turbine's rated power output in kilowatts, its expected capacity factor based on wind conditions at your location, and the current market price for electricity in your region. Input these values into the formula or calculator interface to determine gross annual revenue before expenses. This figure helps you compare different turbine models, evaluate potential sites, and make informed decisions about wind energy investments by providing a clear financial projection.

Day-to-Day Use

Understanding your wind turbine's potential earnings helps with everyday financial planning and decision-making. Whether you're considering installing a small turbine for your home or business, evaluating a larger investment, or simply comparing renewable energy options, this calculation gives you a realistic expectation of income. This knowledge helps you budget for the initial investment, understand your potential return timeline, and make informed choices about whether wind energy aligns with your financial goals and energy needs.

Worked example

A 2 MW turbine at 30% capacity and 8 c/kWh earns about $420k/year.
