How much does a wind turbine cost? The total project cost will depend on many factors, including the cost of the turbine itself, the extent and scope of supporting environmental work for the planning application, the cost of any electrical distribution network (‘grid’) upgrades and the cost of site works including access roads, foundation and cabling costs.
There are economies of scale so larger turbines cost less per kW-installed than smaller ones, and single turbine sites costing more per kW than multiple turbine sites. Having said all of that, a reasonable conservative budget price for the ‘example’ turbines used throughout this webpage would be:
|Maximum Power Output||Typical Turbine Type||Project Cost|
|55 kW||Endurance E-3120||£320k|
|800 kW||Enercon E53/48/44||£1.4 million|
|900 kW||EWT DW61||£1.4 million|
|1.5 MW||GE 1.5sle||£2.7 million|
|2 – 3 MW1||Enercon E82||£3.1 million|
For reference, typically the actual wind turbine costs around 69% of the total project cost.
Want to install a wind turbine?
If you are in the UK then take our Wind Site Self-Assessment - Step 1 of our modular Windpower Feasibility Study. It takes about 20 minutes to work through the basic checks to see if your site might be suitable, including:
- Estimating wind speed
- Checking proximity of nearby properties
- Checking site access and approach roads
- Investigating connection with the grid
