The short answer: the biggest savings on an Australian power bill usually come from fixing the plan, not rationing the heater. Households on an electricity plan more than three years old pay an average of $221 more per year than those on newer plans, according to the ACCC's December 2025 National Electricity Market report.
So before you start rationing showers, run five checks on your plan: how old it is, what the daily supply charge is doing, whether the headline benchmark price has anything to do with your rate, what your solar exports actually earn, and what mode your battery is running in.
None of them require a spreadsheet, just your latest bill and a bit of healthy suspicion.
1. Am I paying a loyalty tax on an old energy plan?
If you haven't switched plans or retailers in a few years, quite possibly. The loyalty tax is the pattern where a retailer wins you over with an attractive rate, then lets it quietly creep up once you've settled in and stopped paying attention.
The ACCC's December 2025 report found the loyalty penalty averages $221 a year nationally, reaching as much as $408 a year in South Australia and $303 in New South Wales. According to ACCC commissioner Anna Brakey, loyalty penalties are alive and well, and the best way to save is to switch, either to a cheaper plan with your current retailer or to a new one altogether.
The catch, as Energy Consumers Australia's CEO Dr Brendan French has pointed out, is that keeping the low rate means switching plans once or twice a year. People have lives, and that's exhausting. Which is exactly what retailers count on.
2. Why is my supply charge going up when I use less power?
Your bill has two main parts. The usage charge covers the energy you use. The daily supply charge is a fixed amount you pay for being connected to the grid, whether you use a lot of power or none at all.
Recent regulatory changes let retailers recover more of their operating costs through that fixed daily charge. The industry calls it a rebalancing. In practice, some customers have faced increases of up to 86 per cent to their daily fixed charge, according to SBS, often paired with a slightly lower usage rate to soften the look of it. Solar Quotes' retail energy report has tracked the same shift.
For anyone trying to reduce a power bill, this is the trap. You can cut your usage all you like, but you can't do a thing about a fixed charge. When you compare energy plans, check the daily supply charge as closely as the cents per kilowatt hour, because the fixed charge is where costs are increasingly being tucked away.
Whether this legally amounts to price gouging is now under formal investigation: Energy Minister Chris Bowen has asked the ACCC and the Australian Energy Regulator to examine whether retailers raising supply charges this sharply have breached misconduct laws.
3. Power prices are falling, so why did my bill go up?
The falling price in news headlines is usually the Default Market Offer (DMO) - the benchmark ceiling the Australian Energy Regulator sets for customers who don't shop around. Fewer than ten per cent of households are actually on a default offer. Everyone else is on market offers that sit below it.
A falling benchmark doesn't automatically lower what you pay. A lower ceiling actually gives retailers less room to discount their market offers, and some appear to be making their cheapest plans more expensive to claw back the margin. So if the news said prices were coming down and your bill went up anyway, the benchmark and your rate were never the same number. Judge your plan on its own figures, not on the headlines.
4. Is my solar feed-in tariff too low?
Plenty of Australian solar owners are on feed-in rates of around 4 cents per kilowatt hour, and some have had theirs cut as low as 2 cents. At those rates, it's fair to conclude exporting isn't worth much bother.
The wholesale market tells a different story. Prices swing throughout the day, crashing towards nothing when solar floods the grid at midday and spiking in the evening. A flat few cents for your exports means someone else is capturing the gap between what your energy is worth and what you're paid for it. With Amber Electric, you're paid the wholesale price for what you export, which during an evening price spike can be worth far more than a couple of cents.
5. Is my home battery earning as much as it could?
Most batteries ship in self-consumption mode. Solar charges the battery by day, the house runs off it at night. It works, and it will cut your bill compared to having no battery. But it was never designed to get you the best return, because the battery has no idea what prices are doing. It just repeats the same loop.
On Amber Electric's wholesale plan, that same battery can do much more. SmartShift, Amber's battery automation, watches the market in real time, charges your battery when energy is cheap or free, and sells what you're not using back to the grid when prices peak, where exports can earn up to $19 per kilowatt hour. You keep 100 per cent of those earnings.
The results can flip a bill entirely:
- Calvin, an Amber customer in Sydney's Inner West, hasn't had a positive bill since switching, cashed out over $3,000 in a year, and has recouped around 30 per cent of his system's cost in two years.
- David's household went from paying close to $3,000 a year to finishing the year $2,146 in credit.
Neither home is running rare or specialised gear. They have the same kind of batteries thousands of Australian homes already own, and the improved return came from putting them on a plan that pays wholesale rates for what they export, combined with automation that sells their stored energy
What makes Amber Electric different from a traditional energy retailer?
There's a reason these five problems all show up together. A traditional retailer buys energy on the wholesale market, adds a markup and sells it back to you. The bigger the markup, the more they make. Confusing bills, rising fixed charges and discounts that quietly lapse all help keep that markup out of sight.
Amber Electric is an Australian energy retailer built the other way around. Customers pay the wholesale price of energy with no markup, solar and battery exports earn the real wholesale rate, and Amber's only margin is a flat monthly subscription that stays the same whether your bill is big or small. There's no gap to widen, so there's no reason to make your bill harder to read.
If you've done the switching, the comparing and the double-checking and your bill still isn't budging, see what you'd pay with Amber Electric.
