Still, the cost of those turbines is higher and makes them more expensive and therefore less attractive as an investment option. Simultaneously, there have been developments in VAWT design and efficiency. When investors consider wind turbines, they need optimum generational efficiency from their investment, and currently, the HAWT systems offer the best ROI. the 25%-40% of the vertical axis turbines. They achieve a typical usage efficiency of 40%-50% vs. Horizontal axis systems placed upwind provide higher efficiency returns than VAWT systems. When it comes to wind turbines, the investors need to weigh up the ability of the turbine to generate electricity based on the available wind conditions at the site. How Turbine Efficiency Influences Investment The swept area would be where the turbines are located over which the wind would blow. The same formula applied to the VAWT turbine would yield between 250 kW and 400 kW across the same swept area. Most turbines operate between 35% and 65% capacity, so if we translate that to a 1MW turbine, the turbine generates between 350 000 W (350kw) and 650 000 W (650 kW).
In simple terms, a 1 megawatt (MW) wind turbine has a maximum generating capacity of 1 000 000 watts if it operates 24/7 and has the required minimum wind speed. Because the wind is never constant, turbines never achieve 100% generational capacity. Wind turbines are rated by how much available wind energy they can capture and utilize. The cost of the turbine itself is usually around 65% of the total, and so this has to be weighed against all factors that could reduce the time and value of the return on investment. The COE is about the turbine itself and requires assessments on the proposed sites regarding wind availability and consistency, whether adverse weather like storms and high winds could affect the generation, and the impact of the installation on the environment.
The COE determines the turbine’s economic efficiency and encapsulates production, operational, and maintenance costs compared to the generational efficiency and consistency of the turbine.īearing in mind that wind turbines are long-term investments, the overall viability of the turbine over its lifetime has to be carefully considered considering the amount of money spent. The COE – Cost Of Energyīefore looking at the actual costs for wind turbines, we need to understand the Cost Of Energy or COE concept. The costs of wind turbines also vary depending on the type of turbine being used as Horizontal Axis Wind Turbines (HAWT) would have different costs to the Vertical Axis Wind Turbine (VAWT) as the design and construction is different. The prices listed above are the cost of production of the turbine itself, and while this may seem high, the costs of wind turbines have decreased over the last decade or so as the technology behind them has improved. Using that cost per MW, you can see that a standard 2-3MW turbine would cost between $2,6million to $4 million, and this would exclude installation costs. While most commercial turbines average around the 2-3MW mark, some larger ones range from 8MW to 12MW. This cost is usually around $1,3million per MW of generating capacity for commercial and industrial turbines. The cost of wind turbines is calculated based on generational capacity, so $/MW (Megawatt) for commercial turbines. How Much Do Wind Turbines Cost? (Calculations + Efficiency) 2ħ How Much Money Do Turbines Generate? How Are Wind Turbine Costs Calculated? Now, let’s look at all the costs associated with wind turbines and then compare that to the potential return on investment.
What other costs are involved with wind turbines.Vertical Axis VS Horizontal Axis turbine costs.How the costs are calculated for industrial.We need to consider the following when looking at the cost of wind turbines: Small domestic turbines would cost between $3000 -$8000 per kilowatt of generated wind capacity, excluding the installation costs. Aside from the upfront costs, wind turbines also have other costs like maintenance which can add to the operational costs over time.Īverage commercial wind turbines with a 2MW capacity would cost between $2,6 million to $4million or around $1,3 million per MW. Wind turbines, whether for industrial or domestic application, are expensive upfront, but the capital expenditure on a wind turbine must be viewed as a medium to long-term investment and not a short-term one.
