Wind Turbines - Generate Electricity at home and save money with the natural power of the wind
What is a wind turbine?
Wind turbines harness the power of the wind and use it to generate electricity.
How do wind turbines work?
- Pole mounted: these are free standing and are erected in a suitably exposed position, with generation capacity of about 5 to 6 Kilowatt (kW).
- Building mounted: these are smaller than mast mounted systems and can be installed on the roof of a home where there is a suitable wind resource. Often these are around 1kW to 2kW in size
- The benefits of wind turbines at home
- Cut your electricity bills: Wind is free, so once you've paid for the initial installation your electricity costs will be reduced.
- Cut your carbon footprint: Wind electricity is green, renewable energy and doesn't release any harmful carbon dioxide or other pollutants.
- Store electricity for a calm day: If your home isn't connected to the national grid you can store excess electricity in batteries and use it when there is no wind.
Costs, savings and financial support
The cost of a system will depend on the size and the mounting method. Building-mounted turbines cost less to install than pole-mounted ones, but they tend to be less efficient.
For equipment and installation, with VAT at 5 per cent:
- a 2.5kW pole-mounted system costs between £9,900 and £19,000
- a 6kW pole-mounted system costs between £21,000 and £30,000.
Building-mounted turbines tend to be less efficient than pole-mounted ones. A well-sited 6kW turbine can generate around 9,000kWh a year. This can save around 3.4 tonnes of carbon dioxide a year.
Wind turbines were eligible for Feed-In Tariff payments. The FITs scheme closed to new applications on 31 March 2019. If you have already installed a wind turbine with a MCS certificate dated on or before 31 March 2019 you may still be able to apply.
