Australian households in New South Wales, the Australian Capital Territory, and Queensland are facing projected increases to their electricity bills from 1 July 2027, following the Australian Energy Regulator’s (AER) final determinations on network revenue proposals. The AER, on 7 October 2026, released its decisions for major network service providers (NSPs), indicating an average annual increase of approximately $85 on typical residential electricity bills across these regions.
This increase stems from the allowed revenue for maintaining and upgrading the poles, wires, and other infrastructure that deliver electricity to homes and businesses. Network charges typically constitute 40-50% of a household’s total electricity bill, making these determinations a significant factor in future energy costs.
What the AER’s Final Determinations Mean for Your Bill
The AER’s determinations set the revenue that NSPs can recover from consumers over the five-year regulatory control period, commencing 1 July 2027. For the first year of this period (2027-28), the projected impacts on average residential bills are as follows:
| State/Territory | Network Service Provider | Projected Annual Increase (2027-28) | Average Percentage Increase (Network Component) |
|---|---|---|---|
| New South Wales | Ausgrid | ~$95 AUD | ~3.8% |
| New South Wales | Endeavour Energy | ~$80 AUD | ~3.2% |
| New South Wales | Essential Energy | ~$88 AUD | ~3.5% |
| ACT | Evoenergy | ~$75 AUD | ~2.9% |
| Queensland | Energex | ~$90 AUD | ~3.6% |
| Queensland | Ergon Energy | ~$98 AUD | ~3.9% |
These figures represent the impact on the network component of a typical residential bill, based on average consumption. The final retail bill impact will also depend on wholesale energy costs, retail margins, and any state or federal rebates in effect at the time.
“The AER’s role is to ensure consumers pay no more than necessary for safe and reliable electricity services, while allowing network businesses to recover efficient costs and invest in essential infrastructure,” an AER spokesperson stated. “These determinations reflect the balance between consumer price impacts and the need for significant investment in grid modernisation and resilience, particularly given the ongoing energy transition.”
Why Are Network Charges Increasing?
The primary drivers behind these approved increases include:
- Inflationary Pressures: Rising costs for labour, materials, and equipment directly impact network maintenance and construction expenses.
- Grid Modernisation: Investments are required to upgrade aging infrastructure and integrate new technologies, such as distributed energy resources (rooftop solar, batteries) and large-scale renewable projects, into the grid.
- System Resilience: Funding for projects aimed at improving grid reliability, particularly in the face of increasing extreme weather events and bushfire risks, is a significant component.
- Decarbonisation Efforts: Network upgrades are essential to support the transition to a cleaner energy system, facilitating the connection of new renewable generation and managing two-way power flows.
While the AER aims to limit price increases, the scale of investment required to transform Australia’s energy grid is substantial. These costs are ultimately passed on to consumers through network charges.
What Can Households Do to Mitigate the Impact?
Despite the projected increases in network charges, households have several avenues to manage their overall electricity costs:
- Energy Efficiency: Investing in energy-efficient appliances, improving home insulation, and adopting smart energy habits can significantly reduce consumption.

- Solar and Batteries: Installing rooftop solar panels and home batteries can reduce reliance on grid electricity, especially during peak demand periods. This allows households to generate their own power and potentially store excess for later use, reducing the volume of electricity purchased from the grid.
- Retailer Comparison: Actively comparing electricity plans and switching retailers can yield significant savings. Different retailers offer varying rates, discounts, and incentives. Even with network charge increases, a competitive retail offer can help offset some of the impact.
- Government Rebates and Support: Keep informed about available state and federal energy rebates and support programs. These schemes can provide direct financial relief or incentives for energy-saving upgrades.

The Broader Context
These network charge determinations are one piece of the complex puzzle that makes up your electricity bill. The AER is also currently consulting on the Default Market Offer (DMO) for 2027-28, which sets the maximum price retailers can charge standing offer customers in NSW, ACT, and Queensland. The DMO decision, expected in mid-2027, will combine with these network charges, wholesale energy costs, and environmental scheme costs to determine the final retail price cap.
While the immediate focus is on the 2027-28 period, the long-term trajectory of electricity prices will depend on the successful integration of renewables, ongoing grid investment, and effective regulatory oversight. Households are encouraged to proactively manage their energy consumption and explore available options to mitigate rising costs.
