The National Grid

The National Grid is a network of cables that distributes electricity around the country. Some of these cables are underground, but most are carried on pylons.

To minimise energy losses, the national grid must operate at a very high voltage (about 100 kV). At the power station, a transformer is used to increase the voltage before the electricity is fed to the national grid. before the electricity can be used in our homes, a second transformer is used to reduce the voltage to 240V.

National Grid is a Public Limited Company (PLC) owning and operating gas and electricity transmission and gas distribution networks in the UK and USA.
