What is a VPP, and is it worth it?
Last updated 2 October 2026
What a VPP is
A virtual power plant (VPP) links many home batteries together under one operator so they can act like a single, much bigger power station. Instead of building one large battery facility, a VPP provider draws a small amount from thousands of home batteries at once, usually during short windows when the grid needs extra supply.
How batteries get aggregated
Your battery stays physically where it is and keeps doing its normal job, charging from solar, powering your home in the evening. The VPP operator's software remotely coordinates every enrolled battery at once during a dispatch event, each contributing a small, pre-agreed share rather than any single battery being drained on its own.
How participants are typically paid
Payment structures vary by provider, but generally combine some mix of:
- A one-off sign-up incentive for enrolling an eligible battery
- Ongoing bill credits applied periodically
- Per-event payments when your battery is actually dispatched
Some of these are run or supported by state governments rather than just retailers. The NSW VPP Incentive and South Australia's REPS VPP incentive are both real examples, each administered through an approved VPP provider rather than paid as a fixed government amount. We don't quote a specific dollar figure for either here as the exact amount is set by the provider, not published as a flat number, see each state's rebate page for what is confirmed.
Backup reserve settings
Most VPPs let you set a reserve, a minimum charge level the operator can't dispatch below, so your battery still has backup capacity left for your own home if the power goes out. It's usually a setting you control, not something that empties your battery without warning.
Brand compatibility limits
Not every battery works with every VPP provider, compatibility depends on the battery's own hardware and software. Based on each manufacturer's own published specs:
- Sigenergy is integrated with several Australian VPP platforms.
- AlphaESS is VPP-ready and FCAS-capable per its datasheet.
- FoxESS (H3 Smart inverter) is compatible with VPP platforms including Amber, Evergen and Synergy.
Always confirm directly with a specific VPP provider before buying a battery for VPP participation, compatibility lists change.
What to compare before signing up
- How you're actually paid, sign-up bonus, bill credit, per-event, or a mix
- Whether you can set your own backup reserve level
- Contract length and any lock-in or exit fees
- Which battery brands and models are eligible
- How much control the provider has over your battery, and how often it's used
Common VPP questions
Will a VPP drain my battery during a blackout?+
Most VPPs let you set a backup reserve the operator can't dispatch below, so your battery keeps capacity available for your own home. Check this is configurable before signing up.
Do I need a specific battery brand to join a VPP?+
Often yes. VPP providers publish their own list of compatible battery brands and models, and not every battery on the market qualifies. Check compatibility with the specific provider before buying.
Can I leave a VPP if I change my mind?+
Most providers allow you to exit, but contract length, notice periods and any exit fees vary. Check the terms before signing up, not after.
BatteryMe VPP: planned
BatteryMe is planning to build its own VPP. It is not available yet. We're not making any claims here about payments, eligible battery brands or a launch date, there's nothing to sign up for yet. This section will be updated once there is something real to describe.
