Australia’s Energy Market Is Changing: What It Means for Homeowners and Small Businesses
Answer: From 1 July 2026, regulated Default Market Offer prices are set to fall for many households and small businesses in South East Queensland. But your own bill still depends on your retailer, tariff, usage habits, solar system, meter type and whether your property is ready for batteries, EV charging and smarter energy use.
Safety & compliance in Queensland
Solar, battery, EV charger, switchboard and electrical installation work should be assessed and completed by a licensed electrician. Do not open electrical equipment, attempt solar repairs yourself, or assume an older switchboard can safely handle new loads. Always check manufacturer instructions, network requirements and Queensland electrical safety rules before upgrading.
Australia’s electricity system is changing quickly. More rooftop solar, large-scale renewables, batteries, smart meters, EVs and data centres are changing how electricity is generated, stored, priced and used.
For homeowners and small businesses, the practical question is not just “will power prices drop?” It is: is your property set up to use electricity safely, efficiently and at the right time of day?
Default electricity prices are expected to fall for many South East Queensland customers
The Australian Energy Regulator has released its final Default Market Offer prices for 2026–27. The Default Market Offer, or DMO, is a regulated safety-net price for standing offer electricity plans in New South Wales, South East Queensland and South Australia. It also acts as a reference price when comparing market offers.
From 1 July 2026, the AER says prices will fall for most households and small businesses on the DMO. In South East Queensland, residential flat-rate standing offer prices are set to fall by 7.2% compared with the previous year. Small business reductions in South East Queensland are set to range from 10.4% to 14.0%, depending on tariff type.
The important detail: this does not mean every customer’s bill automatically drops by the same amount. The DMO does not apply to every plan, and many customers are on market offers rather than standing offers.
| Customer type | South East Queensland DMO change | What it means | What to check |
|---|---|---|---|
| Household on flat-rate standing offer | Down 7.2% | A lower regulated reference price may help, but your actual bill depends on your retailer and usage. | Compare your plan, daily supply charge, usage rates and solar feed-in tariff. |
| Small business on flat-rate standing offer | Down 10.4% | Businesses on standing offers may see a larger reference-price reduction than households. | Check when your business uses power and whether a market offer is better suited. |
| Small business on time-of-use standing offer | Down 14.0% | Time-of-use pricing can reward businesses that shift usage away from expensive periods. | Review peak, shoulder and off-peak use before changing tariffs. |
Batteries are changing how electricity prices behave
Battery storage is becoming more important because it can absorb excess solar and renewable energy during the day, then discharge energy during the evening peak when demand is higher.
Australian Government reporting based on AEMO’s Q1 2026 data says renewables supplied 46.5% of National Electricity Market generation in the March quarter of 2026. It also reported that batteries were shifting more daytime solar into the evening peak, helping moderate prices during high-demand periods.
For homeowners, this is why batteries are getting more attention. A battery may help you use more of your own solar instead of exporting during the day and buying electricity back at night.
For small businesses, batteries may become more relevant if you have high evening usage, expensive peak-period demand, backup-power concerns, or solar production that does not line up well with your operating hours.

Older solar systems should not be ignored
Many Queensland homes and businesses installed rooftop solar years ago. Those systems may still be working, but that does not mean every component is still performing safely or efficiently.
Australian Government solar guidance says solar panels commonly last around 20 to 30 years, while string inverters often last around 10 to 15 years. That means an inverter may need replacement before the panels do.
Signs your solar system may need a check
- Solar production has dropped compared with previous years.
- The inverter shows fault messages or warning lights.
- Your monitoring app has stopped showing reliable data.
- Panels, conduit, cabling or roof mounts look damaged.
- Labels are missing, faded or no longer readable.
- There has been storm, water, hail or pest damage.
- You are planning to add a battery, EV charger or major new appliance.
A solar health check is especially worthwhile before adding new equipment. A battery or EV charger should not be connected to a system that has unresolved faults, poor monitoring, ageing components or switchboard issues. Contact us directly if you have any questions regarding your system and interest in updating your previous system with an appropriately sized battery!
EVs and vehicle-to-grid technology are becoming part of the energy conversation
Electric vehicles are no longer just a transport decision. They are becoming part of the home and business energy conversation.
Vehicle-to-grid, often called V2G, allows a compatible EV battery to discharge electricity back into the grid. Vehicle-to-home, or V2H, allows a compatible EV battery to help power a home. Australian Government EV guidance says new standards have been approved to make it easier for manufacturers to bring V2G and V2H capable vehicles and chargers to Australia.
This technology is still developing and will not suit every property straight away. Compatibility depends on the vehicle, charger, retailer plan, network requirements, approvals, warranty conditions and the electrical setup of the property.
Before installing an EV charger, check whether your switchboard, mains supply, safety switches and available capacity are suitable. For many homes, the charger is only one part of the job; the switchboard and load assessment matter just as much.
Data centres and AI are adding another layer of electricity demand
Australia is also preparing for more electricity demand from data centres, including AI-related infrastructure. These facilities can use large amounts of electricity and may also place pressure on local water, grid connections and infrastructure.
The Australian Government has outlined expectations for data centre and AI infrastructure developers, including supporting Australia’s energy transition, using water sustainably, investing in Australian skills and jobs, and paying their full share of new grid connection costs so those costs are not unfairly passed to consumers or businesses.
For a homeowner or small business owner, this may feel distant. But it is part of the bigger picture: the grid needs to support households, businesses, EV charging, electrification, solar exports, batteries and large new loads at the same time.
What Queensland homes and businesses should do now
The best response is not to rush into every new technology. The smarter approach is to understand your property, check your current electrical setup, and plan upgrades in the right order.
| If you are considering... | Check first | Why it matters |
|---|---|---|
| Changing electricity plans | Your usage pattern, tariff type, solar feed-in rate and daily supply charge. | The cheapest-looking plan may not be cheapest for your actual usage. |
| Adding a battery | Solar performance, inverter age, switchboard condition and evening electricity use. | A battery works best when it is matched to real usage and connected to a safe, compliant setup. |
| Installing an EV charger | Switchboard capacity, circuit protection, cable route, charger location and charging habits. | A poor installation can overload circuits or make charging inconvenient. |
| Upgrading business equipment | Load requirements, operating hours, board capacity and whether demand charges apply. | New equipment can change your peak demand and tariff suitability. |
Before you buy or upgrade
- Review your electricity bill: check whether you are on a standing offer, market offer, flat tariff, time-of-use tariff or demand tariff.
- Look at when you use power: batteries, EV charging and time-of-use plans depend heavily on timing.
- Check solar performance: do not add new equipment to an underperforming or unsafe solar system.
- Assess the switchboard: older boards may need upgrades before EV chargers, batteries or higher loads are added.
- Ask about compliance: make sure the installer considers Queensland requirements, manufacturer instructions and network connection rules.

FAQ
Will my electricity bill definitely go down from 1 July 2026?
Not necessarily. The AER’s Default Market Offer prices are set to fall for many South East Queensland customers on standing offers, but your actual bill depends on your retailer, plan, tariff, meter type, solar setup and how much electricity you use.
Is now a good time to buy a battery?
It depends on your solar production, evening usage, tariff and budget. A battery usually makes more sense when your solar system is working well and you regularly buy electricity after the sun goes down. Have your solar and switchboard checked before committing.
How often should a solar system be inspected?
Follow the manufacturer’s maintenance requirements and Queensland electrical safety guidance. As a guide, older systems, storm-exposed systems and systems with faults or reduced output should be inspected by a licensed electrician with solar experience.
Can any home install an EV charger?
Most homes can install some form of EV charging, but not every property is ready for a high-powered charger without checks or upgrades. A licensed electrician should assess your switchboard, wiring, load capacity and charger location first.
What should small businesses check before changing tariffs?
Check when your business uses the most power, whether demand charges apply, how solar affects daytime usage, and whether equipment upgrades could change your peak load. A tariff that suits one business may not suit another.
