Wind Turbine Profit
Calculate daily and annual wind turbine profit from power generation, electricity price, and operating costs. Free renewable energy ROI calculator with charts and breakdowns.
About This Calculator
The Wind Turbine Profit Calculator helps you estimate the daily and annual profit generated by a wind turbine based on its energy output, local electricity tariff, and operating costs. Whether you are a homeowner considering a small residential turbine or a developer evaluating a commercial wind farm, this tool provides instant ROI projections to support your renewable energy investment decisions.
Wind turbine profit is calculated using the formula WTP = P x EP - DC, where P is the power generated per day (kWh/day), EP is the electricity price per kWh, and DC is the daily cost of the turbine (including amortized installation, maintenance, and operational expenses). The calculator also projects annual profit by multiplying daily profit by 365 days, and displays the profit margin as a percentage of revenue.
Wind turbines capture kinetic energy from the wind and convert it into electricity. The energy available in wind is proportional to the cube of wind speed, making site selection critical. Typical turbine efficiencies range from 30% to 45%, with a theoretical maximum of 59.3% (the Betz limit). Factors affecting output include average wind speed, turbine blade sweep area, air density, and turbine type -- horizontal axis (HAWT) or vertical axis (VAWT).
Regional Notes
India: Electricity tariffs range from ₹5-8/kWh for residential consumers, with feed-in tariffs for renewable energy varying by state. The Ministry of New and Renewable Energy (MNRE) provides guidelines and subsidies for wind energy projects. Typical small wind turbine costs are ₹4-6 crore per MW installed.
United States: Average commercial electricity price is $0.08-0.17/kWh. The federal Production Tax Credit (PTC) and Investment Tax Credit (ITC) can significantly improve wind turbine economics. Many states offer additional renewable energy incentives and net metering programs.
United Kingdom: Electricity prices average £0.15-0.30/kWh. The UK government offers Contracts for Difference (CfD) for large-scale wind, and Smart Export Guarantee (SEG) for small-scale generators. Offshore wind is a major growth sector with falling Levelised Cost of Energy (LCOE).
Frequently Asked Questions
How is wind turbine profit calculated?
Wind turbine profit is calculated as daily revenue minus daily cost. Daily revenue is the power generated (kWh/day) multiplied by the electricity price (per kWh). Daily cost includes turbine amortization, maintenance, and operational expenses. WTP = P x EP - DC.
How much money can a wind turbine make per day?
A typical 1 MW wind turbine producing around 5,000-8,000 kWh per day can generate approximately $400-$800 in daily revenue at $0.08-$0.12/kWh. After accounting for daily costs of $100-$300, daily profit ranges from $100-$700 depending on location, wind conditions, and operating expenses.
What factors affect wind turbine profitability?
Wind turbine profitability depends on average wind speed, turbine efficiency (typically 30-45%), electricity tariff rates, installation and maintenance costs, turbine type (HAWT vs VAWT), and location-specific factors like air density and land lease costs.
Is the wind turbine profit calculator free?
Yes, it is completely free to use with no registration required. All calculations are performed instantly in your browser.
What is the Betz limit and how does it affect profit?
The Betz limit states that no wind turbine can capture more than 59.3% of the kinetic energy in wind. Practical turbine efficiencies range from 30-45%. This directly impacts power generation and therefore the profit you can expect from your wind turbine investment.
How do electricity prices vary by region?
Electricity prices vary significantly: India averages ₹5-8/kWh, the US averages $0.10-0.17/kWh, and the UK averages £0.15-0.30/kWh. The calculator auto-detects your region and suggests local defaults to help you estimate wind turbine profit more accurately.
Can I share my wind turbine profit calculation?
Yes, the URL saves your inputs so you can share the exact calculation with others or bookmark it for future reference.
What is the payback period for a wind turbine?
Payback periods vary widely based on turbine size, wind resource, and local electricity rates. Small residential turbines (1-10 kW) may take 10-20 years, while commercial turbines (1-3 MW) often achieve payback in 5-10 years. Use this calculator to estimate daily profit and compute your expected payback period.
