Generating electricity and power through Wind Turbines in the North East

Eternal Energy can install roof mounted to pole mounted wind turbines to generate renewable energy

Wind turbines harness the power of the wind and use it to generate electricity. Forty percent of all the wind energy in Europe blows over the UK, making it an ideal country for domestic turbines (known as 'microwind' or 'small-wind' turbines). A typical system in an exposed site could easily generate more power your lights and electrical appliances use.

Costs, savings and earnings

Costs

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. For equipment and installation, with VAT at 5%:

  • A roof-mounted 1kW microwind system costs around £2,000
  • A 2.5kW pole-mounted system costs around £15,000
  • A 6kW pole-mounted system costs around £22,500.

Maintenance

Maintenance checks are necessary every few years, and will generally cost around £100 to £200 per year depending on turbine size. A well-maintained wind turbine should last more than 20 years, but you may need to replace the inverter at some stage during this time, at a cost of £1,000 to £2,000 for a large system.

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.

Savings

Building-mounted turbines tend to produce less electricity per kW than pole-mounted ones. A well-sited 6kW turbine can generate around 10,000kWh per year:

  • Equivalent to around 5.2 tonnes of carbon dioxide a year
  • Generating income and savings, if eligible for Feed-In Tariffs, of around £3,200 a year

Benefits of wind turbines

  • Cut your electricity bills:
    Wind is free, so once you've paid for the initial installation your electricity costs will be reduced.
  • Get paid for what you generate:
    Through 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.
  • 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.

Wind Turbines

If you have the space to install. It makes sense to harness the full potential of wind power. Wind power is free and the feed in tariff means the cost is soon recovered as these systems can run 24hrs a day.
