Network tariffs and charges

About network tariffs

There are two main tariff components to your electricity bill:

• A retail component, to recover the purchase cost of energy from the generator
• A network component, to recover the network costs (both distribution and transmission) of delivering energy to your premises. This is a regulated charge levied by the distribution businesses to which the customer is connected (UE), and by the transmission company that owns the transmission assets (SP AusNet).

Network tariffs are directly charged to your retailer by your distributor. Network tariffs are regulated by the Australian Energy Regulator (AER) and represent the cost component referred to as “Network Use Of System” (NUOS). The NUOS is made up of two principal components – Standard Distribution Use of System (DUOS) and the Transmission Use of System (TUOS) – which are added together.

The DUOS component covers the operations and maintenance cost and investment return on our network assets. These assets include zone substations, distribution lines and distribution transformers.

The TUOS component covers the use of transmission power lines/towers and terminal stations.

The elements that make up your electricity bill can be confusing, so if you have any questions or require further information, please call us on 1300 131 689.
