Current snapshot
- The AER said its 2025-26 DMO decision was made in a difficult cost-of-living environment, with pressure across wholesale, network and retail cost components.
- The AEMC's 2025 price outlook now looks at total energy costs, not just electricity prices, because electricity, gas and petrol increasingly need to be considered together.
- Australia now has more than 4 million small-scale renewable energy installations, with the CER saying one in three suitable homes has rooftop solar.
Electricity prices are talked about constantly, but a lot of that conversation is too shallow to be useful. One week the blame falls on wholesale markets. The next week it is networks, gas, policy or retailers. For people paying the bill, that can feel noisy and contradictory. The practical question is simpler: what is actually pushing costs up, how much of that pressure is temporary, and what can a home or business do about it?
Cost of Living and Energy Bills: Why Power Has Become a Bigger Budget Issue matters because electricity is no longer just a utility line item. It is becoming the backbone of home and business energy strategy. Once solar, batteries, EV charging, hot water electrification and smarter tariffs enter the picture, the cost of electricity shapes the value of much broader decisions. That is why looking only at the bill total is not enough.
In Australia, the current picture is clear. The Australian Energy Regulator's 2025 to 2026 Default Market Offer decision lifted standing offer prices in several regions. AEMO's market reporting has continued to show that volatility, weather, outages and network constraints still matter. The AEMC's latest long-range outlook has also made a bigger point: future affordability depends not just on today's price, but on how well the transition to renewables, storage and electrification is coordinated. So this article focuses on the pieces that actually matter, not the usual headlines.
Why this issue is front of mind in 2026
The current concern about electricity prices is not happening in a vacuum. It is grounded in recent regulatory decisions and recent market data. Those signals do not say the same thing, but together they tell a consistent story: the cost of serving customers is still under pressure, and volatility remains part of the picture.

That matters because consumers tend to experience price pressure in two ways at once. First, there are regulated or reference price movements that shape standing offers and influence market offers. Second, there are underlying system conditions, such as wholesale volatility or network constraints, that feed through to risk costs and future pricing. Good decisions need to account for both.
What is actually pushing costs higher
Retail electricity pricing is a stack, not a single number. Wholesale energy is only one component. Network costs matter because poles, wires, system strength and local constraints must still be paid for. Retail costs matter because retailers must fund operations, risk management, customer acquisition and bad debt. Environmental schemes matter because they sit inside the cost of supply. When pressure shows up across several layers at once, consumers feel it.
Households often treat energy bills as fixed overheads, even though behaviour, tariffs, equipment and fuel choice can materially change them.
Gas, petrol and electricity can no longer be planned separately if a household is considering EVs, heat pump hot water or induction cooking.
A bill that looks manageable in one season can become a problem once heating, cooling or transport costs rise at the same time.
That is why headlines about one cause can be misleading. Gas market tightness can matter. Coal outages can matter. Transmission limits can matter. Hot weather or cold still weather can matter. A regulator's decision can matter. But the bill usually reflects an accumulation of pressures rather than a single dramatic event.
Why average market prices and household bills are not the same thing
A household does not usually buy electricity directly at the five-minute wholesale price. Retailers hedge those exposures using contracts. If the market becomes more volatile, those hedging costs can rise. That means a quarter with only a handful of severe price events can still influence future retail pricing. From a customer perspective, that is one reason it can feel like bills move even when average generation conditions seem to have improved.
What households and businesses can do about it
No single response suits every site, but the practical options are usually consistent. First, reduce the amount of expensive grid energy you need to buy at high-value times. Second, improve how flexible loads are timed. Third, plan future electrification so that new electrical demand can be served efficiently rather than simply added to an already stressed bill.
Solar reduces the marginal cost of using electricity during daylight hours.
Electrification can shift spending away from volatile gas and petrol toward electricity, which can then be offset with solar.
Batteries and tariff-aware control can make a household less exposed to expensive evening imports.
It is also worth separating short-term and long-term responses. In the short term, tariff review and load-shifting can help. In the medium term, solar and possibly batteries become relevant. In the longer term, electrification changes the entire household or business energy budget by shifting spend away from gas and petrol.
Common mistakes when reacting to price headlines
-
Comparing only the current quarterly bill instead of the full annual energy budget
-
Ignoring petrol and gas when evaluating solar or electrification
-
Chasing a cheap system without considering long-term operating costs
-
Assuming rebates alone make a project worthwhile
A calmer approach usually wins. The right project is not necessarily the fastest one to install. It is the one that responds to the actual source of cost pressure on the site.
The longer-term view
It is tempting to treat electricity prices as a short-term frustration. That is understandable, especially when people are dealing with seasonal bill shocks. But the more useful view is that households and businesses are moving into an energy system where flexibility has real value. Timing, control and self-generation matter more than they used to. That is not only a market story. It is also a design story.
One of the reasons the AEMC shifted its reporting toward total household energy costs is that electricity is becoming a bigger share of energy spending as homes electrify. That means the effect of solar, load control, EV charging strategy and hot water scheduling can no longer be treated as side issues. They sit at the centre of affordability. A site that is set up well can absorb this change better than one that continues to buy energy in the most exposed way.
For businesses, the same logic applies in a different form. Energy is becoming a more strategic overhead. It affects margins, forecasting confidence and sometimes customer expectations around decarbonisation. That is why the best response to rising prices is rarely a single gadget. It is a better energy system.
What to do before making a solar or battery decision
Start with the bill, but do not stop there. Look at the tariff structure, the timing of your highest usage, and any planned changes in the next few years. If you are thinking about an EV, hot water replacement, reverse-cycle heating, new tenancy patterns or longer operating hours, they all matter. An energy decision made from a static picture can be technically sound and still wrong for the next stage of the property.
The next step is to separate no-cost, low-cost and capital responses. No-cost actions include tariff review and simple behaviour changes. Low-cost actions may include timers, controls or metering improvements. Capital responses include solar, batteries, electrification upgrades and switchboard work. This sequence matters because it avoids solving a timing problem with an expensive hardware answer when a simpler change would have captured part of the value.
Finally, compare options using a few grounded scenarios rather than a single perfect-case estimate. A conservative case, a typical case and a future-electric case will usually reveal far more than one headline savings number. That is particularly true in a market where both retail offers and household or business energy use are evolving.
A practical decision checklist
Before you respond to rising prices with a purchase, check four things. First, what part of your bill is actually hurting? For some sites it is rising daytime energy. For others it is evening imports, winter heating, demand peaks or a growing transport fuel bill that will soon become an electricity bill. Second, what is likely to change in the next few years? A household planning an EV or a business planning longer operating hours should not design for the past.
Third, what can be solved with better timing rather than more hardware? This matters because time-of-use tariffs, controlled loads and flexible appliances can sometimes unlock savings that reduce the size or urgency of a capital project. Fourth, what role do you want the grid to keep playing? Some customers want the lowest practical bills. Others place more value on backup, resilience or reduced gas exposure. The right answer depends on that objective.
If those points are clear, the energy decision becomes much easier. Instead of reacting to headlines, you are designing a response to your own cost profile. That is a much better position for solar, batteries or electrification planning.
Example of how this changes a real decision
Take a household that has rising evening consumption, an ageing gas hot water system and a likely EV purchase in the next two years. If that household reads only a headline about rising electricity prices, it may assume the answer is to install the biggest solar system it can afford straight away. That could help, but it may not be the best sequence. A better sequence might be to review the tariff first, size solar around future daytime opportunity, plan for hot water electrification, and then assess whether battery storage becomes valuable once the evening load is clearer.
Now take a small business that is open during the day, has refrigeration or HVAC loads, and is starting to see more complex tariff structures. That business may initially think its problem is simply expensive electricity. In reality, the bigger issue might be that short intervals of high demand are shaping the bill. Solar may still be part of the answer, but the design brief will be stronger if the business understands the cost mechanism first.
In both cases the lesson is the same. Rising prices do not point to one universal fix. They point to the need for better diagnosis. When the site understands what the bill is reacting to, solar, storage and electrification become far easier to evaluate properly.
One last point, price pressure is not the same as emergency
Rising prices understandably create urgency, but urgency does not always need to mean rushing into the first available hardware decision. In energy, the strongest projects are usually built from a clear view of timing, load and future change. That is especially true now that homes and businesses are becoming more electrified and more flexible.
The practical takeaway is simple. Use current market conditions as a reason to review the whole energy picture, not as a reason to skip that review. People who do that usually make better decisions and keep more of the value over the life of the system.
How Decarby Solar approaches this topic
At Decarby Solar, these discussions usually start well before a customer asks for a quote. We help people separate the headline from the practical decision. That means looking at the tariff, the load profile, likely future electrification, and whether solar or storage will solve the real cost problem rather than the obvious one.
Frequently asked questions
Why talk about total energy costs instead of only the electricity bill?
Because households spend on electricity, gas and transport fuel. Once you consider EVs and electrification, the best decision is often the one that lowers combined energy costs over time.
Can solar help if my bill is high mainly because of winter heating?
Potentially, but solar alone may not solve it. Heating load, tariff structure, insulation, hot water and appliance efficiency all matter. The answer is often a package, not a single product.
Does every household need a battery to manage cost of living pressure?
No. For many homes, solar comes first. Batteries are strongest where evening usage is high, feed-in tariffs are low or backup and tariff shifting matter.
