The blades of the turbine in turn spin a magnet-bearing shaft that is encased within heavy copper coils, a generator. The rotating motion creates massive amounts of electricity.
The electricity generated in the power station reaches our homes, businesses and offices via the National Grid. This grid is a distribution network comprising a UK-wide network of overhead lines and underground cables.
To get from the power station to the customer, the electricity is distributed at very high voltage. With the exception of very large industrial customers like manufacturing factories and such who take their electricity direct from the National Grid, the high distribution voltage needs to be reduced. This is achieved by stepping the voltage down through a series of national, regional and local distribution systems and substations. These act like transformers, eventually reducing in stages the voltage to the 240 volts we're all familiar with in our homes.
