In the very early days of electrical power systems, generation was local and power stations supplied small areas, such as a town.  As the networks developed, it became more economic to generate in larger, central power stations and distribute electricity to the local power stations, which lost their generators and became sub-stations.  Now a substation describes a part of the electricity system where a range of functions are performed, such as transforming the voltage level or connecting parts of the systems, such as a town, factory or generator to the main power network.

Substations range in size from small, local distribution substations such as you might see down your street through to major transmission substations that supply cities and can extend for several acres.  Substations comprise a variety of elements, including switchgear, transformers, protection and control equipment. 

BEAMA members provide entire substations as well as all their components.   Current trends for substations are increasing levels of monitoring and automation, standardisation, lower environmental impact.

BEAMA Networks is the voice of the UK power equipment industry.  We represent manufacturers and suppliers of entire substations and all their components.  The group is dedicated to advancing power networks, reducing costs for consumers whilst making the networks more reliable and adapting to rapidly changing energy world.
