About this calculator
The Wind Turbine Output calculator estimates annual energy generation from wind turbines, using installed power and capacity factor. It helps compare onshore (2-5 MW) and offshore (8-15 MW) projects, assess energy feasibility, or plan grid integration. The formula: Annual Energy (MWh) = Installed Power (MW) × 8,760 annual hours × (Capacity Factor ÷ 100).
Onshore turbines typically have capacity factors of 25-40%, while offshore turbines reach 45-55% due to steadier winds. This tool lets you adjust these inputs for realistic simulations. Remember to account for climate variations, maintenance, and geographic location, which directly impact generation efficiency.
For practical use, enter the turbine's power and capacity factor (based on historical regional data). The result shows the annual available energy, vital for financial return calculations or demand planning. If you lack real data, use category averages (onshore/offshore) for initial estimates.
Frequently asked questions
What's the difference between onshore and offshore turbines?
Onshore turbines (2-5 MW) rely on land-based winds, while offshore ones (8-15 MW) use stronger and steadier winds at sea, achieving higher capacity factors and efficiency.
How does wind variability affect generation?
Intermittent winds reduce the capacity factor. On windless days, turbines generate less energy, which should be offset with annual averages or storage systems.
What capacity factor should I use?
Use 30-35% for onshore and 45-50% for offshore in typical regions. Exceptional wind areas may require adjustments above or below this range.
Can I use this calculator for turbines outside the mentioned sizes?
Yes, simply adjust the installed power (MW) according to the specific model, keeping the formula based on the region's capacity factor.
