Revenue Reset

What is a revenue reset?

As a provider of electricity transmission and distribution network services we are required to submit a regulatory proposal to the Australian Energy Regulator (AER) every five years. Our proposal outlines our plans for planning, building, operating and maintaining Tasmania's electricity network and customer network charges.

At the end of this multi-year process, the AER releases a final decision that confirms our Maximum Allowed Revenue (MAR), or how much we can recover from our customers via our network charges in the new regulatory period.

Our current regulatory period starts 1 July 2024 and runs to 30 June 2029.

Purpose of a revenue reset

Revenue resets are one of the AER’s key regulatory processes, designed to:

  • ensure consumers pay no more than necessary for safe and reliable energy
  • confirm how much an electricity distribution or transmission business like TasNetworks can recover from its consumers over a five-year period

Revenue reset process

The development of each regulatory proposal requires extensive work across multiple teams within TasNetworks. Historically this has taken several years, but TasNetworks now regards revenue resets as an everyday business function, meaning planning for the next regulatory period begins before the last revenue proposal is submitted to the AER.

Developing these proposals, which includes hundreds of individual documents, requires expertise and inputs like network and asset planning, reviews of existing services and strategies, financial forecasting, tariff and pricing modelling. All of this is underpinned by an engagement program with customers and stakeholders to ensure our future program of work supports their immediate and long-term needs and is as efficient as possible.

How we determine customer prices

As part of our regulatory proposal we also need to submit a Pricing Methodology to the AER, detailing how we intend to recover our revenue from customers during each five year period via our network charges. We then also need to revise our network charges each year in accordance with the National Electricity Rules (NER). 

Learn more about how our prices are determined:


The distribution network is the infrastructure that delivers electricity to you. This includes overhead lines, underground cables, power poles and substations.


The transmission network is responsible for receiving and transmitting high voltage electricity from generators and delivering it to the distribution network.


Your electricity bill (and the revenue reset)

The revenue the AER approves for us to recover from our customers has a direct link to your electricity bill. Once revenue is confirmed, our teams adjust our network charges (tariffs) to cover the cost of providing electricity to your home or business.

Our network charges are one of eight different costs in a typical distribution electricity bill. In 2024-25, the network charges account for approximately 42 per cent of the bill. The final overall price Tasmanian distribution customers pay for their electricity is determined by the Office of the Tasmanian Economic Regulator (OTTER) as part of their annual pricing review, completed before the start of each new financial year. OTTER considers all aspects of the bill when setting prices, including our network charges, along with generation, retailer costs and metering. The new prices apply for distribution customers from July each new financial year.
