The charges for using Great Britain’s electricity system

All users of Great Britain’s electricity network pay to use it. Users include generators, who transport the electricity they generate to where it is needed, and demand users, who obtain electricity when they need to use it.

What is charging, and why does charging exist?

How users are charged, and the type of charge they receive, depends on how they use the system. There are four main types of charges:

TNUoS charges

TNUoS charges recover the costs of installing and maintaining the transmission system and are charged to all suppliers and generators.

BSUoS charges

BSUoS charges recover the costs of the day-to-day operation of the transmission system.

Connection charges

Connection charges recover the cost of installing and maintaining connection assets which are required to connect individual users to the GB transmission network.

AAHEDC charges

AAHEDC recovers costs for the north of Scotland which is currently the only area specified to receive assistance.
