Wind Turbines
The UK's position in the world makes it one of the best locations for using wind power. This can be harnessed using wind turbines which generate electricity from the natural resource. 
Natural Wind Power for your home
AAG Swepco design, install and maintain a number of wind turbine systems for homeowners across the UK, with turbines varying from 300 watts to 250 kW and above. In fact, our business provides a range of services to all wind turbine clients, from homeowners to wind farm operators.
Wind turbines can be one of the most effective methods of generating energy when sited in a good location. A correctly positioned wind turbine can generate excellent results, reducing the dependance on the National Grid and carbon emissions from conventional generation methods, whilst the energy costs of the end user.
Wind turbine costs vary between model and energy output - typically homeowners choose a 2.5kW turbine which costs around £11,000-£14,000 depending on the installation type.

More about wind turbines...
There are many parts which make up a small wind turbine system.
1. The Turbine - This converts the energy from the wind into electricity. It does this using highly efficient aerodynamic blades, which are in essence like aeroplane wings or propeller blades. The blades drive the generator round which in turn, generates electricity.
2. The Tower - The turbine needs to be mounted onto a tower so that it is safe from humans and animals. The height of the tower also influences the efficiency of the power generation, generally 'the higher - the better'. This is because nearer to the ground, the wind is slowed by friction with the earth, and buildings and trees cause wind turbulance. We offer three main types of tower, depending on the turbine and local conditions:
- Guyed Tower. This has 4 wire guy wires that go from half way up the tower to the ground, and these enable the tower itself to be a lot smaller, lighter and therefore slightly cheaper, as well as needing smaller foundations.
- Free-standing Tower. This is a single ‘monopole’ which is larger and stronger, and therefore does not need guy wires, and takes up a lot less space on the ground. It however slightly more expensive, and needs larger concrete foundations.
- Roof or building-mounted Tower. This is the simplest yet least effective of tower types. As it's mounted to a building, the air flow can be somewhat different and so in most cases we would not advise such a system.
3. The Inverter - The AC power from the generator is not only the wrong voltage to be connected to the national grid, but also, as the wind speed changes so does the rotational speed of the turbine, and therefore the frequency of the power generated. The power from the generator therefore needs to be converted to DC and then fed into an inverter, to ensure that it is always at 240VAC and 50hz, as required by the UK’s grid system.
4. Cable Trench - Generally a cable trench will need to be dug between where your wind turbine will be installed, and your electrical connection point. Sometimes this might be done using a ‘mole’ which can tunnel a cable duct under a road, or other hard surface.
5. Meters - In order to charge your electricity supplier for any energy that you export to the grid, you need to have a new bi-directional electricity meter installed which will work both when you buy (import) and sell (export) electricity. To claim your sale of Renewable Obligation Certificates (ROCs) you will also need a ROC meter, which keeps track of all the energy your turbine generates, irrespective of it being used by you, or exported to the grid.
