Wind turbines harness the power of the wind and use it to generate electricity, which can be fed into the national grid and generate a significant income through the UK Feed in Tariffs. Small wind turbines known as “microwind” or “small-wind” turbines can produce electricity to help power the lights and electrical appliances in a typical home.

Types of Wind Turbines

In the UK only 0.5% of our electricity requirements are currently generated by wind power. Over the next few decades there are going to be significant investments into wind energy, with the continuation of the domestic and commercial Feed in Tariffs and large investment into wind farms. Wind power varies greatly with wind speed and on an average day can fluctuate dramatically. Individual turbines vary in size and power output from a few hundred watts to two or three megawatts (as a guide, a typical domestic system would be 1 - 6 kilowatts, depending on the location and size of the home).

There are two typical types of domestic wind turbine:

  • Mast mounted: these are free standing and are erected in a suitably exposed position, often around 2.5kW to 6kW
  • Roof 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

Cost & Maintenance

Systems up to 1kW will cost around £1,500 whereas larger systems in the region of 2.5kW to 6kW would cost between £11,000 - £19,000 installed. These costs are inclusive of the turbine, mast, inverters, battery storage (if required) and installation. However, it’s important to remember that costs always vary depending on location and the size and type of system.

MCS Certified Wind Turbines can have a life of up to 22.5 years but require service checks every few years to ensure they work efficiently. For battery storage systems, typical battery life is around 6-10 years, depending on the type, so batteries may have to be replaced at some point in the system’s life.
