Active SA VPP programs
AGL Tesla VPP (formerly SA Government VPP)
The original AusGrid-funded VPP, now operated by AGL with Tesla Powerwalls. Largest residential VPP in the world. Households get reduced retail rates in exchange for dispatch rights.
Amber Electric SmartShift
Amber passes wholesale electricity prices through to retail customers. Battery owners can opt into SmartShift, which charges the battery when wholesale is cheap and discharges when it's expensive. Periodically generates $20+/day in arbitrage.
sonnen VPP
Available to sonnenBatterie owners. In exchange for VPP enrolment, sonnen offers a capped flat-rate electricity plan that often beats market retail.
Notes specific to South Australia
SA has the most developed VPP market in the country. Battery payback periods can drop to 4–6 years with active VPP participation, versus 8–10 years without.
How VPP economics work in SA
VPP earnings depend on two state-specific factors: wholesale electricity price volatility, and grid stress frequency. SA has high daytime solar penetration, which drives wholesale prices to near-zero or negative at midday and very high during the 5pm-8pm evening peak. A battery that can charge midday and discharge during peak earns substantial arbitrage.
Should you enrol in a SA VPP?
Two questions help decide:
- Is your battery 10 kWh or larger? Smaller batteries don't generate enough dispatchable capacity for VPP economics to make sense.
- Are you home in the evening (5pm–9pm)? If you discharge the battery yourself during peak hours anyway, VPP enrolment displaces that discharge to grid export — net economically positive only if the per-event payment beats the difference between your import and feed-in rates.
For most SA households with a 10–13.5 kWh battery and average evening usage, VPP enrolment adds $300–$900/yr to total solar income. We'll model the exact number for your address when we get in touch.
Common questions
What VPP programs are available in South Australia?
SA currently has 3 active residential VPP programs: AGL Tesla VPP (formerly SA Government VPP) (AGL / Tesla), Amber Electric SmartShift (Amber Electric), sonnen VPP (sonnen). Each has different payment models and battery brand compatibility — check the details below.
How much can I earn from a VPP in South Australia?
SA has the highest VPP returns in the country thanks to extreme daytime wholesale price volatility. Active VPP participants commonly earn $800-$1,500 per year on top of normal solar feed-in income. Amber Electric customers with smart-shift batteries occasionally see $2,000+.
Do I need to switch retailers to join a VPP in SA?
Sometimes. Retailer-led VPPs (AGL, Origin, Powershop) require you to be on their retail plan. Operator-led programs (Tesla, Reposit, Amber, sonnen) operate alongside or as their own retail backend. We'll flag the trade-off when we get in touch.
Does SA require VPP enrolment for the federal battery rebate?
No. The federal Cheaper Home Batteries Program requires your battery to be VPP-capable — meaning it can support enrolment — but actual enrolment is optional. You can claim the rebate and never join a VPP.
