Use Cases

Evaluate a potential wind turbine investment

Input your turbine's rated power, expected capacity factor, operating hours, electricity price, and annual operating cost to estimate yearly profit and assess feasibility.

Example: A 2 MW turbine with 0.4 capacity factor, 8000 h/year, $0.05/kWh, and $50,000 cost yields $270,000 profit.

Compare different turbine configurations

Adjust the rated power, capacity factor, or operating hours to see how changes affect energy output and profit, helping you choose the best setup for your site.

Example: Compare a 1.5 MW vs 2 MW turbine with same capacity factor and costs.

Frequently Asked Questions

How is the annual energy production calculated?
Annual energy (kWh) is calculated by multiplying the rated power (kW) by the capacity factor (fraction) and the operating hours per year (h/year). For example, a 100 kW turbine with a 0.35 capacity factor operating 8000 hours yields 280,000 kWh.
What does the capacity factor represent?
The capacity factor is the fraction of time the turbine actually produces at rated power, accounting for wind variability, maintenance, and downtime. Typical values range from 0.2 to 0.5 for onshore sites.
How is profit calculated?
Profit is calculated as annual revenue (energy output × electricity price) minus the annual operating cost. The calculator shows both revenue and cost, so you can see the net profit.

Tips & Common Mistakes

Tips

  • Use a realistic capacity factor based on your site's wind resource. Typical onshore values are 0.25–0.45, offshore can be higher.
  • Operating hours should reflect actual availability, not just 8760 hours. Include downtime for maintenance and grid outages.
  • Electricity price should be the rate you receive or avoid paying, including any feed-in tariffs or net metering credits.
  • Include all annual operating costs: maintenance, insurance, land lease, and administrative expenses.

Common Mistakes to Avoid

  • Using 8760 hours as operating hours without accounting for downtime, which overestimates energy output.
  • Confusing capacity factor with efficiency; capacity factor is a fraction of rated power over time, not a percentage of energy conversion.
  • Forgetting to subtract operating costs when calculating profit, or using inconsistent currency units.
