However, even if commercial wind turbines cost a lot in total, they become cheaper per kW of energy they produced. Larger turbines drive a need for technology development at a component level, as offshore wind turbines use the largest castings, bearings, generators and composite structures in series manufacture in any industry. Your wire run losses are greater when you have direct current (DC) instead of alternating current (AC). A 1.5 kW turbine would cost approximately $8,000 and $12,000 and deliver around 2,600 kW over a year depending on your location and wind speeds. A standard 1kW building mounted turbine installation costs around £2000, with a 2.5kW turbine costing around £15,000 and a 6kW around £23,000 including installation costs. The cost of a wind turbine system may vary considerably so make sure you get at least three quotes from reputable MCS accredited installers. This explains the necessity of federal grants and stimulus available to the renewables market. The cost per kW typically varies from around €1,000/kW to €1,350/kW. At this time in 2009 and considering the current costs of turbines, turbine installation, and maintenance, along with the current price of 7.2 ¢/kWh, wind-generated power seems not the best financial decision a power company could make. At this rate, over its 20-year estimated lifespan, the turbine would produce a total of 156,640 kWh (7832 kWh annually X 20 years). The wind turbines for residence and farm are less expensive, when a KW energy production capacity applies to the rates. Larger turbines help drive down the per MW cost of foundations, installation and operation, whilst reaching higher into the wind field, so increasing energy production per MW installed. If you are planning to install a wind turbine for commercial purposes, expect to spend millions of dollars. Source: Calculations by the author based on selected data for European wind turbine installations .
The total cost per kW of installed wind power capacity differs significantly between countries, as shown in Figure 1.1.
Installing a 10 kW wind turbine can cost you a total of $50,000 on the lower end and up to $80,000 on the higher end. Offshore wind farms have a large construction cost and are almost as expensive as residential wind production when it comes to dollars per kW. Sizes … Development costs of commercial wind turbines vary greatly depending on the location of generation and capacity. One of the most recent additions to U.S. offshore wind capacity sits three miles off of the coast of Block Island, Rhode Island. The commercial wind turbine cost is about $1- $2 million a MW nameplate capacity installed and if you buy the same turbine in 2 MW, its cost would be about $2.8 million. Domestic Wind Turbine Costs. European wind turbine installations Operation and maintenance (O&M) costs for onshore wind energy are generally estimated to be around 1.2 to 1.5 c€ per kWh of wind power produced over the total lifetime of a turbine. The SeaTitan 10MW, therefore, although not priced at the time, could cost in the neighborhood of $20 million. The wind speed characteristics are analyzed statistically based on a long-term hourly data record to evaluate the proper wind energy potential. Do as much research as possible! Pole mounted domestic wind turbine. Unit costs go up as size and capacity decline. Urban and Suburban Wind Turbine System (turbine only, tower and installation not included) – $6,500 to $15,500 The Helix Wind Savonious is a revolutionary design that can be used in urban and suburban settings because of its very small footprint and ease of installation.

Typically larger systems cost more to install but can generate more electricity, delivering you bigger energy savings and larger tariff payments. Using an online wind production calculator, we find that this turbine costs around $13,750 ($3,700 per kW) to install and produces about 7,832 kWh a year. Solar PV module prices have fallen by around 80% since the end of 2009, while wind turbine prices have fallen by 30–40%. A larger array that has a 15 kW capability would cost in the region of $100,000 and return approximately 36,000 kW of energy over a year. The costs for a utility scale wind turbine range from about $1.3 million to $2.2 million per MW of nameplate capacity installed. include wind turbine (e.g., wind turbine components), balance of system (e.g., development, electrical infrastructure, assembly, and installation), and financial costs (e.g., insurance and construction financing). While there is no available "average cost" of a wind turbine, there is, at least for large turbines, an average cost per megawatt. If you have a long wire run, it is advisable to invert DC to AC. All MCS approved installers should be able to provide a detailed breakdown of the specification and costs of their proposed system.
