Synergy Battery Rewards is WA's virtual power plant. When the grid is busy, Synergy can use your home battery to send power back, and you get a bill credit for every kWh it sends.
Bigger batteries can send more power per event, so they earn more. Find your home size below.
| Home size | Battery size | Per year |
|---|---|---|
| Smaller home | 10 to 15 kWh | $29 to $88 |
| Medium home | 20 to 30 kWh | $59 to $176 |
| Big home | 30 to 40 kWh | $88 to $235 |
| Very big home | 40 kWh or more | $118 or more |
Estimate only: 70¢/kWh × about 70% of the battery sent per event × 6 to 12 events a year.
On top of this
You need all 7. Your installer checks most of these at quote time.
Your battery goes in through the WA Residential Battery Scheme
Battery Rewards is only open to scheme batteries right now. Buying or leasing a home that already has a compatible scheme battery also counts.
Your inverter is on Synergy's approved list, under DER-StorageCheck model codes
Sungrow, GoodWe, Sigenergy and many others qualify. Being on the list isn't enough on its own: the Tesla Powerwall 3 is listed, but not under DER-Storage or the WA scheme, so it doesn't get the rebate.
You're a Synergy home customer on an eligible plan
Home Plan (A1), Home Business Plan (K1), Midday Saver, or the Electric Vehicle Add On.
Your battery stays online
It needs a reliable internet connection, and keeping it online is your job. A new Wi-Fi password, router or internet provider takes it offline until it's reconnected. Offline, your system is limited to 1.5 kW of export.
Your system is big enough
Inverters rated at least 2.5 kVA (one or combined) and at least 5 kWh of battery, meeting Synergy's Tier 1 and Tier 2 requirements.
No life support, and no other VPP
Homes with registered life-support equipment can't join, and you can't be in another VPP at the same time.
You're on the Western Power network
Perth metro and the South West (SWIS grid only).
Quoted a specific model? What to check on Synergy's approved list before you sign.
Events happen when the grid is busy on very hot or very cold days, usually a run of 30 to 35°C+ days when air conditioners are working hard across Perth.
A little, but not much. These are the figures most installers and warranty documents quote.
Your warranty
You can have both. Power sent in an event earns the DEBS rate as well as the 70¢/kWh credit.
| Compare | DEBS (distributed energy buyback scheme) | VPP (Synergy battery rewards) |
|---|---|---|
| Who decides when | You control when to export | Synergy controls the timing |
| What you earn | 10¢/kWh 3pm to 9pm, 2¢/kWh other times | 70¢/kWh in events, plus DEBS rates |
| How you sign up | Apply once ($7.53 inc GST), plus a two-way meter | Sign the Battery Rewards agreement |
| Who can join | Eligible Synergy customers with a new or upgraded system | Compatible (VPP-ready) systems only |
Under the current WA rules, you need to join (Tier 2 registration) to get the WA Battery Scheme help:
$130/kWh, up to $1,300
rebate for Synergy customers (10 kWh max eligible)
Up to $10,000
interest-free loan, household income under $210,000
For most homes, yes: the credit is worth more than the extra wear, and your DEBS export credit still applies during events.
Before you stay out
Good to know
A plain-English framework for deciding if Battery Rewards fits your goals.
Why 30 events a year is not 30 extra cycles, and what a throughput warranty actually caps.
Synergy customers get $130/kWh back, capped at $1,300.
