Australian households and businesses face varied impacts on their electricity bills for the 2026-27 financial year, following the Australian Energy Regulator’s (AER) approval of annual pricing proposals and network charges for electricity distributors across most states. Published on 24 April 2026, these decisions will see network charges largely increase, with a notable exception in Victoria, as the energy market continues its complex transition.
The network charges, which constitute a significant portion of a typical electricity bill, are set to rise in the Australian Capital Territory, New South Wales, Northern Territory, Queensland, South Australia, and Tasmania. The AER’s assessment ensures these proposals align with National Electricity Rules and each distributor’s five-year regulatory revenue determination.
Drivers Behind the Increases
The primary factors contributing to the upward trend in network charges include established revenue paths from previous determinations, escalating transmission costs, persistent inflation, and the recovery of previously under-recovered revenue by distributors.
New South Wales consumers will see increases partly driven by costs associated with the state’s Electricity Infrastructure Roadmap. In South Australia, rising transmission costs also encompass the recovery of expenses related to the Firm Energy Reliability Mechanism, a critical component for maintaining grid stability.
Queensland’s Cyclone Recovery Costs
In Queensland, Energex, the state’s largest electricity distributor, received AER approval for a significant cost pass-through. This allows Energex to recover AUD$66.1 million in incremental costs incurred due to Tropical Cyclone Alfred. These costs will be recovered across the 2026-27 and 2027-28 regulatory years, directly impacting electricity bills in South-East Queensland.
Victoria’s Unique Outlook
While most states are preparing for increased network charges, Victoria presents a contrasting scenario. The AER is still assessing pricing proposals for Victorian electricity distributors in May, following the release of final determinations for the 2026-31 regulatory period. However, initial high-level estimates suggest a potential average annual decrease of AUD$6 to AUD$38 in the distribution component of Victorian residential electricity customers’ bills across the 2026-31 period.
This projected decrease is attributed to forecast higher demand, which is expected to spread the approved revenue increases across a larger customer base, ultimately leading to lower per-customer bills than in the current period. The actualisation of these savings will, however, depend on whether the anticipated demand increases are realised.
“We have carefully considered all submissions and feedback from stakeholders and reviewed the proposed expenditure to ensure that it is clearly justified, timely and efficient,” said AER Board Member Lynne Gallagher, regarding the revenue decisions. “Following our assessment, we have either accepted, rejected or in some cases, identified other solutions to address consumers’ concerns and deliver the outcomes they were seeking at a lower cost.”
Impact on Retail Prices and Consumer Action
These approved network charges are foundational for retail electricity prices. Retailers will incorporate these underlying costs into the prices offered to customers for the upcoming 2026-27 year. The AER acknowledges that electricity bills remain a significant concern for many households and businesses across Australia.
To help consumers navigate these changes and find the most suitable energy plan, the AER encourages the use of its Energy Made Easy website, a free and independent price comparison tool.
Looking ahead, the AER will integrate the approved network charges for New South Wales, South Australia, and South-East Queensland (Energex) into the final 2026-27 Default Market Offer (DMO), which is slated for publication by 26 May.

Summary of Approved Network Charge Impacts (Distribution Component, 2026-27)
| State/Territory | General Trend | Key Drivers | Specifics |
|---|---|---|---|
| ACT | Increase | Revenue paths, transmission costs, inflation, under-recovered revenue | N/A |
| NSW | Increase | Revenue paths, transmission costs, inflation, under-recovered revenue, NSW Roadmap costs | N/A |
| NT | Increase | Revenue paths, transmission costs, inflation, under-recovered revenue | N/A |
| Queensland | Increase | Revenue paths, transmission costs, inflation, under-recovered revenue | Energex: +AUD$66.1M for Tropical Cyclone Alfred recovery (2026-28) |
| South Australia | Increase | Revenue paths, transmission costs, inflation, under-recovered revenue, Firm Energy Reliability Mechanism costs | N/A |

These changes underscore the ongoing evolution of Australia’s energy grid and the regulatory efforts to balance investment in infrastructure with consumer affordability. Consumers are advised to review their energy plans and consider options for managing their electricity usage in light of these new charges.
