How Much Does A Wind Turbine Cost?
For homeowners, businesses, utilities and governments assessing the economic viability of wind energy, the pivotal question arises – how much does the average wind turbine
The capex costs of supercapacitors are contrasted with the costs of lithium ion batteries and the costs of flywheels in the chart below. A typical supercapacitor stores about 15 seconds of energy, for a capex cost of $10,000/kWh, but just $40/kW of power.
A typical supercapacitor stores about 15 seconds of energy, for a capex cost of $10,000/kWh, but just $40/kW of power. This is down to very high power density (10-25 kW/kg, 10-25x higher than a lithium ion battery), albeit quite low energy density (2-10 Wh/kg, which is 95-99% below a lithium ion battery).
According to HomeGuide, the average cost for a commercial wind turbine ranges from $2.5 million to $4 million, with prices typically around $1 to $1.25 million per megawatt. Onshore turbines generally have capacities between 2 to 4 megawatts, while larger offshore turbines can cost significantly more, often exceeding $100 million.
Large offshore turbines can cost tens of millions of dollars, with the most powerful 12 MW turbines reaching up to $400 million for manufacturing and installation. Lastly, Statista reports that the global average installed cost for onshore wind power was approximately $1,160 per kilowatt in 2023.
