Virtual Power Plants: What They Are and How Australians Can Benefit
A virtual power plant (VPP) connects thousands of home batteries, solar systems and smart devices into a coordinated energy network that earns participants bill credits or cash.
A virtual power plant is a network of small, distributed energy resources — home batteries, solar inverters, EV chargers, smart thermostats and controllable loads — coordinated by software to behave like a single large power plant. When the grid needs support, the VPP operator dispatches these resources collectively. Participants are compensated for the grid services they provide.
How a VPP Works in Practice
You install a home battery (or already have one) and enrol with a VPP operator. You retain ownership and control of your battery for most purposes. During grid stress events — typically heatwaves, evening demand peaks or network incidents — the operator automatically discharges a small amount of your stored energy into the grid. In return, you receive bill credits or direct payments. The events are typically brief (15–60 minutes) and have minimal impact on your home energy use.
VPP Programs Available in Australia
| Program | Operator | Who can join | Reward type |

| AGL VPP | AGL | AGL solar/battery customers | Bill credits |
| Origin Loop | Origin Energy | Origin battery customers | Bill credits / cash |
| Reposit Power | Reposit | Compatible battery brands | Cash for grid dispatch |
| Amber + battery | Amber Electric | Battery owners on wholesale tariff | Export earnings at spot price |
| SA Government VPP (SAPN) | SA Power Networks | SA residents with batteries | Completed 2023 — ended |
Financial Rewards
Earnings from VPP participation in Australia vary significantly by program and market conditions. Conservative estimates based on current programs suggest $100–$400 per year in bill credits or cash for a standard 10–13 kWh battery. During high-demand periods like extreme heatwaves, dispatch events can pay much more. For batteries enrolled in wholesale pass-through programs like Amber, earnings depend directly on spot prices during dispatch.
Benefits Beyond the Financial
- VPPs reduce the need for fossil fuel "peaker" plants that run only during peak demand spikes
- They make the grid more stable by responding instantly to frequency changes
- They enable more renewable energy on the grid by helping smooth out production variability
- AEMO has identified VPPs as a key tool for managing the transition to a high-renewable grid
VPP dispatch events are typically brief and unnoticeable. You won't come home to a flat battery — operators are contractually limited in how much they can draw and must leave you with adequate reserve for household needs.
Should You Join a VPP?
If you have a compatible home battery, joining a VPP is almost always worthwhile. The financial upside is positive, the inconvenience is minimal and the grid benefit is real. The key questions are: which program is available for your battery brand, and whether the reward structure suits your usage patterns. Check with your battery installer for compatible programs.
