What is a VPP, exactly?
A Virtual Power Plant aggregates thousands of residential home batteries (and sometimes hot-water systems and air conditioners) into a single dispatchable resource for the electricity market operator. The VPP operator — usually a retailer (AGL, Origin) or specialist (Tesla, Reposit) — has the right to draw on a portion of your battery's stored energy during specific high-value moments: peak-demand events, frequency response, or wholesale market price spikes.
You keep priority access to your own battery. Typical contracts reserve 20–30% of capacity for your own use at all times, and many cap dispatch at 50% of available capacity per event.
VPP programs by state
Australia's residential VPP landscape is highly state-specific because of retail market structure differences. Pick your state for the operators active in your area:
The three VPP payment models
1. Per-event payment
You're paid a fixed amount each time the VPP dispatches your battery (typically $1–$5 per event). Best for transparency — you can see exactly what you earned. Reposit and Energex GridReady use this model. Annual earnings: $200–$600.
2. Discounted retail plan
Instead of paying you per event, the operator gives you a cheaper electricity plan in exchange for VPP rights. Tesla's Energy Plan and sonnenFlat both work this way. Best for households that import a lot of electricity — the discount is most valuable when your usage is highest.
3. Wholesale market exposure
Amber Electric passes wholesale electricity prices through to retail customers. Battery owners can charge when wholesale is cheap and discharge when it's expensive. Best annual returns ($800–$1,500) but requires comfort with variable pricing. Available in SA, VIC, NSW, ACT, QLD.
What you give up by joining a VPP
- Some battery capacity during dispatch events (typically capped at 50% per event)
- Internet dependency — your battery needs reliable broadband to participate
- Lock-in to a specific retailer in most retail-led programmes (Tesla, AGL, Origin)
- Marginally faster cycle wear — extra dispatch events accelerate battery degradation
The cycle-wear penalty is usually small (5–10% over 10 years) and compensated by the per-event payments.
Should I join a VPP?
Three quick rules:
- Yes, if you live in SA, VIC, NSW, or ACT (high volatility, strong returns), have a 10+ kWh battery, and have reliable internet.
- Maybe, if you live in QLD or WA (regulated retail; check what's available in your area) — the answer is programme-specific.
- Probably not, if you have a small battery (under 7 kWh), live in TAS (low grid volatility), or rely on the battery primarily for blackout backup.
Common questions
What is a Virtual Power Plant (VPP)?
A Virtual Power Plant is a network of distributed home batteries that an operator can remotely dispatch to support the grid during peak demand events. Your battery still serves your home first; the VPP gets to draw on the remaining capacity at high-value moments. In exchange, you receive a flat per-event payment, a discounted electricity plan, or a higher feed-in tariff.
Is VPP participation mandatory under the Cheaper Home Batteries Program?
No — but your battery must be VPP-capable. The federal Cheaper Home Batteries Program (launched 1 July 2025) requires the installed battery to support VPP enrolment, but actual enrolment is optional. You can claim the rebate, install the battery, and never enrol if you prefer.
How much can I earn from a VPP?
Typical residential VPP returns sit between $200 and $1,500 per year, depending on your battery size, your state's wholesale price volatility, and which programme you join. South Australia (highest volatility) generates the strongest returns; Tasmania (most stable grid) generates the least.
Will the VPP drain my battery during a blackout?
No. Modern VPP contracts include a reserved minimum charge (typically 20–30% of capacity) that the operator can't dispatch. Your home retains backup power even during grid stress events.
Can I leave a VPP if I'm not happy?
Yes. Most residential VPPs are no-lock-in agreements that you can exit at any time, typically with one month's notice. Check the specific T&Cs of each programme.
