Australian homeowners navigating their electricity bills into 2027 can anticipate a mixed but generally more favourable outlook. For most households in New South Wales, Victoria, and South East Queensland, Default Market Offer (DMO) and Victorian Default Offer (VDO) prices are set to decrease from 1 July 2026 to 30 June 2027. This translates to average annual savings of up to $229 for some households, though South Australian flat-rate customers will see a modest increase.
This shift is primarily driven by a significant reduction in wholesale electricity costs, fuelled by increased renewable energy generation and battery storage capacity across the National Electricity Market (NEM). However, it’s crucial to remember that these are default offer prices; genuine savings for most households will depend on actively engaging with market offers and utilising available rebates.
The 2026-27 Default Market Offer & Victorian Default Offer Explained
The Default Market Offer (DMO), set by the Australian Energy Regulator (AER), acts as a safety net for residential and small business customers on standing offer contracts in New South Wales, South Australia, and South East Queensland. Victoria has its own equivalent, the Victorian Default Offer (VDO), set by the Essential Services Commission (ESC). Both are reviewed annually and apply from 1 July each year.
These offers also serve as a crucial reference price, against which retailers must compare their market offers, making it easier for consumers to gauge the competitiveness of different plans.
State-by-State Residential Price Changes (1 July 2026 - 30 June 2027)
The AER and ESC released their final determinations in May 2026, outlining the following changes for residential customers on standing offers:
| State/Region | Tariff Type | Price Change (vs. 2025-26) | Annual Impact (Approx.) |
|---|---|---|---|
| New South Wales | Flat Rate | Decrease 3.4% to 5.0% | Save $66 to $137 |
| Time-of-Use (TOU) | Decrease 3.7% to 7.7% | Save $72 to $211 | |
| South East Queensland | Flat Rate | Decrease 7.2% | Save $155 |
| Time-of-Use (TOU) | Decrease 10.7% | Save $229 | |
| South Australia | Flat Rate | Increase 1.4% | Add $33 |
| Time-of-Use (TOU) | Decrease 1.1% | Save $25 | |
| Victoria | Average Flat Rate | Decrease 5.0% | Save $84 |
Note: Annual impacts are based on typical residential consumption benchmarks and may vary based on individual usage and distribution zone.
For instance, a typical Victorian household on a flat tariff can expect their average annual bill to be $84 lower in 2026-27 compared to the previous year, based on 4,000 kilowatt-hours (kWh) annual usage.
Driving Factors: Wholesale Prices and Renewables
The primary reason for these price adjustments is a significant easing of wholesale electricity costs. The Australian Energy Regulator noted that wholesale costs fell between 2% and 14% for the coming financial year. This contrasts sharply with the dramatic swings observed in late 2025 and early 2026, where average spot prices jumped from $48.98 per MWh in November 2025 to $152.25 per MWh in January 2026.
Key contributors to this downturn include:
- Increased Renewable Generation: More wind and solar power entering the system. Renewable generation reached a record 41.7% of total supply in August 2026.
- Battery Storage Expansion: Rapid deployment of grid-scale and home batteries is playing a much larger role in balancing supply and demand, particularly during evening peaks. Batteries met 49% of the grid’s dispatchable power needs during the evening in August 2026, up from just 0.4% in 2020.
- Reduced Gas Reliance: Australia’s dependence on gas for power during the evening peak (5 pm to 8 pm) fell by nearly 70% in the year to August 2026, as batteries filled the gap. Domestic gas prices declined sharply in Q2 2026, averaging $9.05 per gigajoule (GJ), down 26.8% from Q2 2025, which further reduces electricity generation costs.
“Australia’s wholesale electricity prices were about 45% lower over the same period compared to surging prices in the EU and Japan, demonstrating how renewable energy and battery storage can protect electricity markets from global fuel price spikes.”
While these factors contribute to lower wholesale costs, network charges (the cost of poles, wires, and infrastructure) remain the largest component of a typical bill, accounting for approximately 38% to 50%.
The End of Universal Federal Energy Relief & What’s Next
Homeowners should be aware that the universal federal Energy Bill Relief Fund ended on 31 December 2025. This means the automatic credits of up to $300 (2024-25) and a further $150 (first two quarters of 2025-26) are no longer applied to electricity bills.
From January 2026, bills reflect full retail prices without this Commonwealth offset. While this may feel like an increase, it’s the removal of a subsidy, not a rise in underlying prices. Existing state and territory-based targeted concessions for eligible cardholders (e.g., pensioners, healthcare card holders) remain active.

Actionable Strategies to Reduce Your 2027 Electricity Bill
Despite the generally positive DMO/VDO outlook, homeowners can take proactive steps to further reduce their energy costs in 2027:
-
Shop Around for Market Offers: The DMO/VDO is a safety net, not necessarily the cheapest option. Retailers often provide more competitive market offers. Use government comparison websites like Energy Made Easy (NSW, SA, SE QLD) or Victorian Energy Compare (VIC) to find the best deal for your specific usage patterns. Always compare the full annual cost, including daily supply charges and usage rates (c/kWh).
-
Embrace Time-of-Use (TOU) Tariffs and Smart Meters: With the introduction of the new Solar Sharer Offer in DMO regions (NSW, SA, SE QLD) from 1 July 2026, smart meter households can access 3 hours of free power in the middle of the day. This offers a significant opportunity to shift high-consumption activities (like running dishwashers, washing machines, or charging EVs) to these free periods, potentially saving up to 24 kWh daily. Even without the Solar Sharer Offer, TOU tariffs can be beneficial if you can shift usage to off-peak hours.

-
Invest in Solar and Batteries: The long-term trend for electricity prices is still influenced by volatile fossil fuel costs. Installing rooftop solar panels, especially when paired with a home battery, provides significant insulation from grid price fluctuations. Federal Small-scale Technology Certificates (STCs) offer an upfront discount on solar and heat pump hot water systems, although the value reduced slightly on 1 January 2026.
Consider exploring options like:
-
Electrify Your Home: Transitioning from gas to electric appliances can lead to long-term savings as gas prices continue to be a financial burden for many households. Rebates are available for heat pumps, induction cooktops, and efficient air conditioners. Read our guide: Electrify Your Home in 2026: Real Costs, Rebates & Savings Up to $15,000+
-
Maximise Rebates and Concessions: Don’t miss out on state and federal support. From Solar Victoria rebates (up to $1,400 + $8,800 interest-free loan) to the NSW Low Income Household Rebate ($285/year), significant savings are available. The federal Household Energy Upgrades Fund also offers low-interest loans for energy efficiency improvements.

Bottom Line
Australia’s electricity price forecast for 2027 indicates a period of stabilisation and even reduction in default market offer prices for most homeowners, largely thanks to the increasing penetration of renewables and battery storage in the energy mix. While the universal federal energy bill relief has ended, the regulated safety net prices (DMO and VDO) are generally trending downwards from 1 July 2026. However, to truly minimise your energy expenditure, proactive engagement is key. Compare market offers, leverage smart meter tariffs, and explore the extensive state and federal rebates available for energy-efficient upgrades and solar battery installations. Taking these steps can lead to significant annual savings beyond the baseline reductions.
