Electricity networks and tariffs

What are network tariffs and are your charges accurate?

Energy distributors

The energy distribution network, sometimes called networks, includes the power lines, power poles or pipelines that supply energy to your business. There are different distributors for each state and territory. For power outages, gas leaks or emergencies, often the networks are best to advise.

Network tariffs

The network charge or tariff on your invoice is advised to us by your energy distributor. The tariff is a regulated charge invoiced to Origin and then passed through on your invoice to cover the cost of building, maintaining and operating the poles and wires and for delivering electricity to your site. The charge is calculated based on your consumption and will appear on your invoice as both a peak and off-peak components. 

You can find more information about network tariffs on the AER website:



Is your business on the most appropriate tariff?

Network tariffs can make up over 30% of your electricity bill. We can review your network charges to make sure you’re not paying too much.

Do network charges change?

Network charges can change due to:

Annual network tariff price change

Typically, network providers review the prices associated with their network tariffs on an annual basis. Each network provider submits a submission to the Australian Energy Regulator for review and approval, and Origin is formally notified of the changes to the network tariff.

Network review of your consumption

The network provider may also conduct a tariff review which may instigate a change of tariff for your site typically in response to a significant increase or decrease in demand or load at your site. Occasionally, network providers undertake a review of the overall tariff structure and make some tariffs obsolete or introduce new tariffs.  

Origin/customer-instigated tariff review

Origin may, at your request, review the suitability of your existing network tariff and facilitate, on your behalf a formal request for change of network tariff to the network provider. Once approved by the network provider, this change will be reflected on your invoice from the nominated effective date. Your tariff can generally only be changed once per annum in this manner.

How is the network charge calculated?

Network charges are rates multiplied by your consumption to calculate the charge that will appear on your invoice and typically have both a peak and off-peak component.  Network charges are referenced on your invoice as:

  • Network off-peak
  • Network peak
  • Network shoulder – where applicable

The network charges on your invoice will reflect the network tariff advised to us by your provider.

How is demand calculated?

Demand is a measurement of capacity or the rate at which energy is used. Sometimes called a power charge or capacity charge, demand charges are measured in kilowatts (kW). 

Demand represents the greatest amount of energy used in 15-30 minute intervals during a billing cycle. To measure demand, electric meters record the average demand usage over each 15-30 minute period and record the highest (peak) period for the month.  Through the demand charge, each business pays its share of the utility’s investment in generation, transmission and distribution equipment standing by to serve.
