The combination of solar, batteries and Virtual Power Plants is transforming how Australians think about energy. What was once a one-way relationship is now interactive, flexible and increasingly consumer-driven.
For years, the role of households in Australia’s energy system was relatively simple. Energy retailers and networks supplied the energy, and consumers used it.
The rise of rooftop solar changed this; suddenly, households weren’t just consuming energy – they were generating it too.

AGL spokesperson Jane Butler, General Manager Electrification and Innovation says solar panels allowed Australians to produce their own electricity, power their homes during the day and get paid to feed any excess back to the grid.
“But the rise of home battery systems is reshaping that dynamic,” Jane says.
Today’s energy-savvy households are taking things one step further.
With the addition of battery storage and smart technology, smart energy consumers are becoming “prosumers” – consumers who also produce, store and actively manage their own electricity.
And now, with the rise of Virtual Power Plants (VPPs), those individual systems are being connected into something even more powerful.
From passive bill-payer to active energy player
Adding a battery to your solar system changes how your home interacts with energy.
Instead of sending unused solar power back to the grid during the day – often for a relatively low feed-in tariff – you can store that energy and use it later, like in the evening when demand (and prices) are typically higher.
This means you can rely less on the grid, make better use of the energy you generate and gain more control over your electricity usage.
But when that battery is connected to a broader network, like AGL’s Virtual Power Plant, it becomes part of something much bigger.
A power plant in your postcode – how VPPs actually work
A Virtual Power Plant (VPP) is essentially a network of connected solar batteries that can work together when the grid needs extra energy – operating like a traditional power plant, but without a single physical location.
Instead of one large generator, Jane says a VPP draws small amounts of stored energy from thousands of individual batteries across different homes.
“By drawing a limited amount of stored energy from each battery, the VPP creates a large pool of energy that can be shared to the grid to help support it when needed – for example, on a summer’s day when everyone is running their air-conditioners,” Jane explains.
“This coordinated approach helps reduce pressure on the grid, improve reliability and support the broader energy system as it transitions towards renewables.”
The feel-good factor (with real-world impact)
There’s a clear community benefit to participating in a VPP.
By allowing a portion of your stored energy to be shared when it’s needed most, you’re helping stabilise the grid and support other households during peak demand periods.
It’s a small contribution at an individual level – but when thousands of homes participate, the collective impact can be significant.
At the same time, you’re still getting more value from your own solar system, making better use of the energy you generate rather than letting it go to waste.
Backup power and peace of mind
Beyond grid support, battery systems can also offer greater resilience at home.

“If you select a battery with backup power capability, you can keep running your essential appliances when there is a power outage,” Jane says.
“AGL will always leave you with power in your battery.”
Jane says this is something that’s becoming increasingly valuable as extreme weather events and peak demand periods put pressure on the grid.
“AGL’s approach ensures that you’ll always retain some power in your battery, so you’re not left without energy when you need it most.”
This added layer of reliability is one of the key reasons more Australians are considering battery storage as part of their home energy setup.
The financial upside – more ways to get rewarded
While there’s a strong sustainability and reliability case for batteries and VPPs, there’s also plenty of financial benefit, too.
By storing your solar energy and using it strategically, you can reduce your reliance on grid electricity – particularly during peak pricing periods.
On top of that, programs like AGL’s Virtual Power Plant (VPP) and Battery Rewards Plan1 are designed to provide additional value.
A VPP is a network of solar batteries that can work together when the grid needs extra energy, just like a power plant. By drawing a limited amount of energy from each battery, the VPP creates a large pool of energy that can be shared.
If you’re eligible and choose to participate, Jane says you can receive bill credits based on how much energy you export back to the grid through the VPP.
“The amount you earn depends on how much you export,” Jane says.
“You choose how much energy to export, and there are no penalties for exporting your full battery.”
Turning your battery into a smart savings tool
Alongside potential bill credits, AGL’s Battery Rewards Plan 1 offers lower overnight electricity rates.
This means you can charge your battery from the grid when prices are cheaper – and then use or export that energy when it’s more valuable.
For households on time-of-use (ToU) tariffs, this can create an additional opportunity to optimise energy usage.

In simple terms, it allows you to “buy low and use high” – charging your battery at lower rates and benefiting from higher-value energy later.
Combined with solar generation, this creates a more dynamic and responsive energy system within your home.
Who can get involved?
If you live in South Australia, Victoria, New South Wales or Queensland – and already have a battery installed – you may be eligible to connect to AGL’s Virtual Power Plant.
Once connected, your system becomes part of a broader network designed to support grid reliability while helping you unlock more value from your energy setup.
It’s a shift that reflects a broader change happening across Australia’s energy landscape – one where households are no longer just end users, but active participants.
