Wind Turbines

Generate wind powered electricity with a small wind turbine for your home

Win Turbines - Wind powered sustainable electricity systemWind turbines save energy by harnessing the power of the wind and use it to generate electricity.
Forty percent of all the wind energy in Europe blows over the UK, which means it’ ideal country for domestic wind turbines (known as ‘microwind’ or ‘small-wind’ turbines). A typical wind powered system in an exposed site could easily generate more electricity than your lights and electrical appliances use.  Energy Savings Trust


The benefits of wind turbines

  • Wind turbines cut your electricity bills
  • Wind energy is free so after initial installation your electricity costs will be reduced.
  • Get paid for the electricity you generate 
  • Through Government Feed-in-Tariffs, you get paid for the electricity you generate even if you use it. What you don’t use, you can export to the local grid – and get paid for that too.
  • Wind turbines reduce Carbon Dioxide Emissions
  • A wind turbine system stores electricity
  • If your home isn’t connected to the national grid you can store excess electricity in batteries

How Wind turbines work

Wind turbines use large blades to catch the wind. When the wind blows, the blades are forced round, driving a turbine which generates electricity. The stronger the wind, the more electricity produced.

There are two types of domestic-sized wind turbine:

  • Pole mounted Wind Turbines: these are free standing and are erected in a suitably exposed position, often around 5kW to 6kW
  • Building mounted Wind Turbines: 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.

Two electricity-generating technologies for the home: wind turbines and solar electricity.

 

Wind Turbines – Savings and income

Building-mounted turbines tend to produce less electricity per kW than pole-mounted ones. A well-sited 6kW turbine can generate around 10,000kWh and the equivalent of around 5.2 tonnes of carbon dioxide a year.

Wind turbines &  Feed-in Tariffs

Wind turbines are eligible for Feed-in Tariffs. You will earn a tariff for each kWh of electricity generated by your system. You will also receive another tariff for each kWh of electricity you export. Please note that the Feed In Tariff is not available in Northern Ireland. For the latest Feed-in Tariff rates please go to the Energy Savings Trust  Feed-in Tariff pages. You can also visit  the Energy Savings Trust  Cashback Calculator to find out how much you could save and earn through Feed-in Tariffs. Energy Savings Trust 


Wind turbines are eligible for the UK government’s Feed-in-Tariffs which means you can earn money from the electricity generated by your turbine.

You can also receive payments for the electricity you don’t use and export to the local grid.To be eligible, the installer and wind turbine product must be certified under the Microgeneration Certification Scheme (MCS).

If your turbine is not connected to the local electricity grid (known as off grid), unused electricity can be stored in a battery for use when there is no wind.

Please note that the Feed-in Tariffs scheme is not available in Northern Ireland. Energy Savings Trust

 


Wind Turbine Maintenance

Maintenance checks are necessary for Wind Turbines every few years –  They will generally cost around £100 to £200 per year depending on turbine size. A well-maintained turbine should last more than 20 years.

For off-grid systems, batteries will also need replacing, typically every six to ten years. The cost of replacing batteries varies depending on the design and scale of the system. Any back-up generator will also have its own fuel and maintenance costs.
