Is a home battery worth it in Victoria? Savings & payback in 2026

I get asked this more than any other question, so here's my honest answer: for a lot of Victorian homes, yes. But "worth it" is about more than the payback number, and I'll be upfront about where the maths gets tight.

The short version, as of October 2026: with our retail partners, a battery of around 10 kWh with blackout protection starts from about $8,900 after the federal rebate. If it covers 10 kWh of your evening and overnight use, I estimate it saves around $1,240 a year, which pays a $10,000 battery back in roughly 8 years. Use less power at night and that stretches to 13 years or more. Then there's everything the payback doesn't count, which I'll get to.

Why the numbers look better in Victoria now

Two things have changed, and both work in a battery's favour:

Selling your solar back earns almost nothing

The Essential Services Commission no longer sets a minimum feed-in tariff in Victoria. Since 1 July 2025, retailers choose their own rate, and the floor is zero. On most of the bills our team looks at, the feed-in tariff is now 1 cent per kWh or less. So every kWh you export earns next to nothing, while buying it back in the evening costs 40 cents or more. Storing it instead is where a battery earns its keep.

Free power in the middle of the day

Since 1 October 2026, the Victorian Midday Power Saver gives households with a smart meter three hours of free electricity every day, from 11am to 2pm. The Victorian Government confirms that home batteries can charge from the grid during that window.

This is the part I'm most excited about. A battery used to rely on your solar to fill it, and in a grey Melbourne July that often didn't happen. Now it can top up for free even on a cloudy day, then run your home through the expensive evening peak.

It isn't free money for everyone, though. It's a time-of-use plan, and its other rates can be higher than what you pay now. For 2026–27, the 4pm to 9pm peak is about 40 to 50 cents per kWh and overnight power is about 23 to 25 cents, depending on your area (Essential Services Commission). With a battery covering those expensive hours, that trade-off usually works out well. Without one, compare it carefully with your current plan.

What a battery actually costs after the rebate

Rather than quote national averages, here are real starting prices for battery packages through RebateSpy in Victoria, as of October 2026. They're for a single-phase home, fully installed, after the federal battery rebate, and every one includes blackout protection:

• Around 10 kWh: from about $8,900
• Around 15 kWh: from about $9,800
• Around 20 kWh: from about $10,200

Premium all-in-one brands, like Tesla, Sigenergy and Sungrow, generally sit between about $14,000 and $20,000. Brand matters more than size here, which is why a premium 10 kWh battery can cost more than a good-value 15 kWh one. A three-phase home, a switchboard upgrade or a tricky install can also add to the price.

What's included matters as much as the price

You've probably seen ads for a big battery, fully installed, for around $5,000. Some of those are starting prices. Extras like blackout protection, or a longer cable run when the battery sits more than a few metres from the switchboard, can be added once the installer has seen your home.

The prices above already include blackout protection. Before we quote, we ask for photos of your switchboard, your existing system and where you'd like the battery, so the extras are priced in upfront. If something unexpected comes up on installation day, we cover it. In the rare case a site needs major extra work, like a long trench, we'll tell you before anything is installed. Whoever you compare, ask for the full list of what's included before you sign. Our guide to the lowest quote trap shows what to look out for.

One thing surprised me when I lined these up. On some brands, a 20 kWh battery costs only a few hundred dollars more than the 10 kWh version, partly because the federal rebate grows with the battery. With free midday power to fill it, a bigger battery can make a lot of sense, as long as you'll actually use the extra storage. A bigger battery can also help you earn more feed-in credits if you switch to a plan that offers higher feed-in tariffs during the evening peak, by setting your battery to export some power in the evening, although you also want to make sure you keep enough charge to cover your overnight usage. Our guide to what size battery you need helps you work that out.

My worked example

Here's how I'd estimate it for a typical Melbourne home. These are my assumptions, so treat the result as a guide, not a promise.

• Battery: 10 kWh usable, at $10,000 after the rebate. That's towards the more affordable end of our partners' prices.
• Plan: the Midday Power Saver, with peak power at 44 cents and overnight power at 24 cents per kWh, both within the 2026–27 ranges.
• Charging: from your solar or the free midday window, so storing each kWh costs you nothing, or about 1 cent in lost feed-in.
• Use: half of what the battery supplies covers the 4pm to 9pm peak, and the other half covers overnight.

If you use about 10 kWh after the sun goes down

5 kWh at 44 cents plus 5 kWh at 24 cents is $3.40 a day. That's about $1,240 a year, and a payback of around 8 years.

If you use about 6 kWh after dark

3 kWh at 44 cents plus 3 kWh at 24 cents is $2.04 a day, or about $745 a year. Payback stretches to around 13 years. Honestly, for a household like this I'd look at a smaller battery before a bigger one.

Real savings will move around a bit. A battery loses a little energy each time it charges and discharges, electricity prices change every year, and a virtual power plant could add something on top.

Your electricity plan matters as much as the battery

The same battery can save very different amounts depending on the plan it's paired with. It's the part of a proposal we spend the most time on, because it's where most of the savings are won or lost. Right now there are three main approaches in Victoria.

The Midday Power Saver

Free power from 11am to 2pm, and published rates for the rest of the day. It's simple and predictable, which is why I've used it for the example above.

Amber with SmartShift

Amber passes on wholesale electricity prices, which change every five minutes. Its SmartShift software runs your battery for you, using forecasts of prices, your solar and your usage to decide when to charge, when to use your stored power and when to sell it back to the grid. The upside can be big, especially when prices spike. The trade-off is that prices aren't fixed, so your bill moves with the market, and Amber manages the battery day to day rather than you. You do also have the ability to manually tell the battery what to do using the Amber app as well, if you think you’ll benefit more from holding power you can manually set that up on the Amber app.

GloBird ZEROHERO

GloBird's ZEROHERO plan is the more predictable option. It gives you a free charging window in the middle of the day (12pm to 3pm for new customers), a $1 daily credit if you avoid drawing power from the grid between 6pm and 9pm, and bonus credits for exporting from your battery in the evening peak. Your battery is set to charge in the free window and run your home or export in the evening, and we can even help you set that up.

Both work as virtual power plants (VPPs), where your battery helps the grid at busy times and you're paid for it. In our proposals, we usually model your savings on Amber or GloBird, depending on your battery and how hands-on you want to be, and compare that with what you're paying now. Not every battery works with every plan, so it's worth checking before you choose.

The rebate drops on 1 January 2027

The federal rebate depends on the date your battery is installed. From 1 January 2027, a battery with 10 kWh of usable capacity earns 57 STCs instead of 68, $418 less at $38 per STC (Clean Energy Regulator). I wouldn't rush a decision to save $418. But if you're already leaning towards a battery, it's worth starting the conversation now, because installers get busy before Christmas. Another thing to consider is that the difference in the rebate increases as the battery size increases, so if your usage warrants a bigger battery than 10kWh, the reduction in rebate value would be higher than $418. Here's what the January change means.

Why I don't judge a battery on payback alone

If payback were all that mattered, I'd tell some people to wait. But from the families we talk to, it's rarely the reason they're happiest with their battery a year later. Here's what the maths leaves out.

Blackout protection

This is the big one for me. Every battery package we put together with our partners includes blackout protection as standard, because keeping the lights, the fridge and the internet on during an outage is one of the best reasons to own a battery.

One thing worth understanding: how much of your home stays on depends on the battery's inverter. Each one can only supply so much power at once. If too many big appliances run together during a blackout, the system can trip and you'd have to reset it. So we back up the circuits that matter most and keep their combined load under that limit. Before you sign, ask exactly which circuits are covered.

Protection from price rises

Electricity prices are reset every year. Every kWh your battery supplies is a kWh you're not buying at next year's price, whatever that turns out to be. I think of it a bit like locking in part of your bill.

Peace of mind

Using more of your own solar, leaning less on the grid in the evening, and knowing you've got backup when a storm takes the power out. It's hard to put a dollar figure on that, but it matters to a lot of the people we help.

So, is a battery worth it for you?

Here's my take. I think a battery is likely worth it if:

• you use 8 kWh or more in the evening and overnight
• you have solar, or you're adding it, plus a smart meter for the Midday Power Saver
• you'd value keeping the power on during blackouts
• you plan to stay in your home for at least the next 8 to 10 years

I'd hold off, or go smaller, if:

• your evening use is low and you're out most nights
• you're planning to sell in the next few years
• you're only doing it for the dollars and your payback comes out well past 10 years

If a battery doesn't stack up for you today, that's okay. The rebate runs until 2030, battery technology keeps improving, and things like an electric car or going all-electric can change the numbers quickly. It's worth checking again in a year or two, and we're happy to help then too.

And if you've read this far and a battery sounds right for your home, we’d love to help. Our team will look at your bills and usage, recommend the battery and electricity plan that suit how you use power, and put together a package with one of our vetted retail partners, with blackout protection and the likely extras priced in upfront.
