How does it connect to the National Grid?

A wind turbine generates power by converting the kinetic energy in the wind to rotational energy by means of the blades and then into electrical energy in the generator. This electrical energy needs to be at mains voltage and frequency before it is of any use in your house, farm or business. Different turbines do this in different ways, some generate a variable voltage and then smooth it out using rectifiers and inverters and others control the generator directly to match the grid.

Most installations will be connected ‘behind the meter’ which means that any power you generate will be first used by your own property, thereby saving you the maximum amount possible on your electricity bill. Any excess energy your wind turbine generates, e.g. on windy days or at night, is "spilled" to the National Grid and your electricity supplier pays you for it. Larger turbines may need their own grid connection and will therefore export all of the energy produced.

All grid connected onsite generating equipment must automatically switch off if the grid connection should fail. This means that should the grid connection fail, there is no danger to any maintenance engineers fixing the fault. This does however mean that the wind turbine will produce no power to the property if the mains connection fails.

Grid Connection Application

For all single phase grid connected turbines, which have a rated power of more than 3.6kW, Myriad CEG needs to apply to the local electricity supply company for permission to connect your turbine to the grid. This also applies to multi-phase installations where the maximum power per phase exceeds 3.6kW.

Myriad CEG have a great deal of experience in getting these permissions and in minimising the costs of any necessary upgrades.
