2028-2033 Revenue Proposal

The draft plan sets out how we propose to balance affordability and reliability with the changing needs of the energy system.

It's part of the development of Transgrid’s Revenue Proposal for 2028-2033, also known as RP4. The Revenue Proposal will set out how we propose to invest in the transmission network over the next five-year regulatory period.

The plan has been shaped by extensive input from members of the public, advocates, industry and government. We're now seeking feedback from consumers before we finalise the Revenue Proposal and submit it to the Australian Energy Regulator (AER) for independent assessment.

The energy system is changing. More renewable generation is connecting to the grid as older power stations retire. How much electricity is needed, and when and where it’s needed, is changing too.

The draft plan explains how the network will adapt, manage costs carefully and continue to be safe, secure and reliable, as well as where we’re still seeking input. It focuses on five outcomes:

1. Keeping costs fair and affordable by making careful investment decisions and maintaining the services consumers rely on.
2. Being open and accountable by clearly explaining costs, benefits, uncertainties, the choices involved and how feedback has shaped the plan.
3. Shaping the plan with consumers by using feedback to test assumptions, set priorities and improve the plan.
4. Keeping the network safe, secure and reliable as equipment ages and risks from extreme weather, changes in the energy system and cyber threats increase.
5. Preparing the network for the future as electricity needs change and more renewable energy connects to the grid.

We combined technical analysis and business planning with input from consumers, advocates, customers, industry, government, regulators and Transgrid employees.

Our advisory groups also helped shape the draft plan:

• The Consumer Advisory Group, which replaced the Transgrid Advisory Council (TAC) in 2026, provided independent consumer-focused advice.
• The Consumer Working Group (CWG) provided more detailed input on proposed investments, assumptions and how we engaged.

This feedback helped us:

• Focus investment where it’s expected to deliver the greatest benefit.
• Review and refine proposed spending.
• Make better use of existing assets where it’s safe and efficient.
• Explain costs, benefits, uncertaintiesand choices more clearly.
• Balance keeping costs down with the network’s long-term needs.

Transgrid cannot set its own prices. The AER independently assesses our plan, including:

• The work proposed.
• The associated costs.
• The expected impact on electricity consumers.

The AER applies the National Electricity Rules to decide how much Transgrid can earn from the transmission network. It considers whether proposed spending is efficient, prudent and in consumers’ long-term interests.

Transmission is one part of your electricity bill. Your bill also covers electricity generation, local distribution networks,retail services and government programs. 

Investment in the transmission network affects electricity bills. The impact will depend on the AER’s final decision and changes in other parts of the energy supply chain.

The draft plan includes forecast spending, expected benefits and potential bill impacts so people can consider the proposed choices.
