  • Industry information

These pages contain details about the charges that users of the electricity transmission system have to pay, how they are calculated and what changes are currently being considered by the industry.

What is charging?

There are four different types of charge which we bill our customers. You might be liable to pay one - or all of them, depending on the type of transmission user you are.

Why does charging exist?

Our charges exist to recover the costs of installing and maintaining as well as the day-to-day and the day-to-day operation of the transmission system. There are also charges relating to the installation and maintenance of connection assets and assistance for areas with high electricity distribution costs
