A VPP pays you to let someone else discharge your battery when the grid needs power. The payments are real. So is the wear, and most comparisons of VPP providers do not mention it.
Read the throughput clause in your battery warranty before you read any VPP offer. Most warranties expire at a stated energy throughput or cycle count, whichever comes first, and VPP participation reaches that limit years earlier than household use alone. If a program earns you $400 a year and costs you three years of warranty on a $12,000 battery, that is not a good trade.
With that established, here is what the market looks like and how to compare it. Our Complete Guide covers the underlying mechanics in more detail.
What a VPP Actually Does
Your battery, aggregated with thousands of others, dispatched as if it were a single generator.
The operator discharges your stored energy into the grid during demand peaks or price spikes, and sometimes charges it when prices are low or negative. In return you get bill credits, a higher feed-in rate, trading payouts, or a sign-up incentive, depending on the program.
The grid benefit is genuine. Distributed storage responds faster than a gas peaker and defers network investment. That is why state governments subsidise participation.
What to Compare
Battery compatibility. The hard gate. VPPs support a specific list of battery models, and if yours is not on it, nothing else matters. Check before you buy a battery if VPP income is part of your business case.
How much control you keep. Some programs let you set a minimum reserve so the battery never drops below, say, 30%, preserving blackout backup. Others take more control and give you fewer opt-outs. If you bought the battery for resilience, a program that can empty it before a storm defeats the purpose.
Number of dispatch events. The figure that determines wear. Ask for the expected events per year and the typical depth of discharge per event, then work out the annual throughput against your warranty limit. Programs that will not give you that number are telling you something.
Payment structure. Fixed feed-in uplift, per-event payments, trading upside, or bill credits. Fixed structures are predictable and usually pay less. Market-linked structures pay more in a volatile year and nothing in a quiet one.
Whether you must switch retailer. Many VPPs are tied to a specific retailer, so joining means taking that retailer's usage rates and daily supply charge too. A good VPP payment attached to an uncompetitive energy plan can leave you worse off overall. Compare the total annual cost, not the VPP payment in isolation.
Solar and EV integration. Whether the program optimises your solar generation and any EV Charger alongside the battery, or only dispatches the battery.
Your state. Availability and incentives vary considerably, and some of the better arrangements are state-backed.
Who Operates in Australia
The landscape moves, so treat this as a starting list rather than a current price comparison.
Amber Electric passes through wholesale prices and lets your battery trade against them, for a monthly subscription. The highest upside and the highest variability, and it works properly only with automation that responds to price signals. Suited to a larger battery and an owner comfortable with an unpredictable bill.
Discover Energy combines a fixed feed-in rate with bonus payouts from market trading. More predictable than Amber, and it requires switching retailers.
AGL runs a straightforward program dispatching stored energy during peak events. A simple entry point, particularly for existing AGL customers, with correspondingly modest returns.
SolarHub operates mainly in the ACT and NSW, often through local installers, with region-specific incentives.
Synergy in Western Australia is state-backed, pairing rebates with guaranteed VPP participation for eligible battery owners. Where you qualify, state-backed programs are usually the better deal.
sonnenVPP works with sonnenBatterie systems across several states, which makes it relevant only if you own or are buying that hardware.
How to Decide
Three questions, in order.
Does the program support my battery, and does it leave me the reserve I want? If either answer is no, stop there.
What does it cost me in warranty? Expected annual throughput from dispatch events, against the throughput limit in your warranty. Convert that into years of warranty life consumed.
What is the total annual position? VPP earnings, minus any worse energy rates if switching retailer is required, minus the amortised warranty cost. That is the real number, and it is often much smaller than the headline payment.
For a household that already has a battery on a supported model, with a program that preserves a reserve and dispatches modestly, a VPP is usually worth joining. For a household considering buying a battery specifically to earn VPP income, the case is much weaker, and the arithmetic rarely survives an honest accounting of the wear.
Ask each provider for expected events per year and typical depth of discharge in writing. That single question separates the programs worth joining from the ones that are quietly expensive.
