From Turbine To Home - How Does Electricity Get To Our Homes?

Whether it's to sit down after work and watch Netflix, to cook our dinner, or to charge our phones, we all rely on having electricity in our homes – and nothing makes us happier here at GB Energy Supply than providing you with this energy. It isn't quite as simple as flicking on a switch or pressing the on button though - electricity generation starts way back at the power station, and goes through a huge number of stages before it gets to our homes.

Take a look at our video below, and learn exactly how electricity is generated, and how it gets to our homes.

In the UK, the majority of our electricity is produced through burning fossil fuels such as coal, gas and oil. These fossil fuels account for just over 60% of the country's total power generation. Although eco-friendly sources are beginning to become more common, with wind energy taking the lead, these do not yet come close to producing the same level of power as fossil fuels.

The procedure in which these fossil fuels are converted into electricity for our homes is actually far more complicated than it may first seem. It begins back at the power station where the coal, gas or oil are burned in order to generate heat.

Power Station Scheme

The heat is used to turn water into steam, which then rises to power the blades of a turbine. This turbine converts the heat energy into mechanical energy, which is then placed through a generator. The generator uses an electromagnetic field to convert the mechanical energy into electrical energy.

The fossil fuels have now successfully been converted into electrical energy, but this energy is not yet strong enough to be transmitted through the power lines of the national grid. In order to do this, a transformer is used to convert the energy into a higher voltage of around 765,000 volts, once this is done the energy is ready to be distributed around the country.

Fossil Fuel Conversion Energy

Once the energy has travelled through the national grid, the voltage then needs to be brought back down. A second set of transformers takes care of this, bringing the energy down to around 4,000 volts.

The energy then reaches the final network of distribution lines, but the power is still far too great for our homes. A final set of transformers lowers the energy voltage once again, to a level of around 120-240 volts.

Now that the energy is at the appropriate level for our household appliances, it is ready to enter our homes and be used in our day-to-day lives.
