AEMC Fixed Charge Proposal: What Property Investors Should Check Before 2030
This story matters because a higher fixed charge changes the bill psychology. When more of the cost is fixed, using less power does not reduce that part of the bill. The AEMC says network pricing reform could still reduce total network costs over time and lower bills for many households, with its latest modelling released on 23 April 2026 setting out the A$6 billion savings claim. Critics say the same shift could punish low-usage, solar, battery and vulnerable households if retailers pass the structure straight through as the Smart Energy Council argued in response.
What Is Actually Being Proposed?
The AEMC pricing review is looking at how electricity products, network tariffs and retail offers should work as more households add solar, batteries, electric vehicles and electric appliances. The review was self-initiated on 25 July 2024 and is still open according to the AEMC project page.
The controversial piece is draft Recommendation 5. In plain English, it points toward network tariffs with two parts: a dynamic usage component that rises when the local network is congested and falls when capacity is available, plus a fixed component to recover unavoidable shared network costs. The AEMC distributional analysis describes this as a staged reform over about 10 years, starting in FY30 in its April 2026 modelling paper.

|---|---|---|
| AEMC status | Review open. Draft report published 11 December 2025. Final report expected June 2026. | Do not treat the proposal as a finished rule. |
| AEMC modelling | The AEMC says reform could deliver up to A$6 billion in cumulative network savings over 15 years. | Useful for context, but individual bills depend on retailer offers and customer behaviour. |
| Consumer risk | HoustonKemp says higher fixed charges could create adverse bill impacts for low-usage households if passed through. | This is why consumer protections matter. |
| Lodgey action | ATO rental records guidance expects separate property records and evidence for expenses, assets and capital works. | Energy bills should be stored like any other property cost. |
Why Everyone Is Arguing About Fixed Charges
The AEMC argument is fairness and system efficiency. If households with solar or batteries can avoid more network costs through lower grid imports, households without those options can end up carrying more of the shared poles-and-wires cost. Energy Networks Australia makes that case directly, saying the driver is to recover residual costs more proportionately while preserving incentives for consumer energy resources in its pricing review explainer.
The counterargument is control. If the fixed part of the bill gets too large, a household that reduces usage, installs efficient appliances, or adds solar may feel like the goalposts moved. The Smart Energy Council says households that use the least electricity are most at risk, naming renters and pensioners among the groups under pressure in its call to pause the changes.
The Property Investor Angle
If you own a standard long-term rental, your tenant often pays the retail electricity bill. But the proposal can still matter to your investment. It can affect tenant affordability, solar and battery payback, short-stay profit, common-area costs, vacancy costs and the records your accountant needs at tax time.
| Property setup | Who feels it first? | What to check |
|---|---|---|
| Long-term rental | The tenant usually pays the retail bill. | Watch tenant affordability, solar payback, embedded utilities and energy upgrade records. |
| Short-stay or included utilities | The owner often pays the bill. | Fixed supply charges hit every low-occupancy month, even when usage is low. |
| Apartment or strata | Costs can appear through common area power or levies. | Keep strata statements, levy notices and capital works evidence by property. |
| Vacant or renovation period | Usage may drop but supply charges keep running. | Tag vacancy days, advertising evidence and improvement invoices. |
This is where Lodgey's tax lens matters. The ATO's rental property guidance says investors need records to work out rental income, deductible expenses and CGT outcomes, and to prove who incurred an expense under its rental record rules. The ATO also separates rental expenses into categories such as common property expenses, depreciating assets, repairs, maintenance, capital expenses, borrowing expenses and interest on its rental expenses page. Energy-related costs need the same property-by-property discipline.
For Airbnb-style or furnished rentals where utilities are included, a higher fixed charge can keep running even when bookings are thin and usage is low.

No one knows your future retail plan. This tool is deliberately illustrative. Use it to understand the break-even logic: a higher fixed daily charge can be offset by a lower usage rate, but only once the property uses enough grid electricity.
