I check VPP participation in three steps: can the equipment communicate with a VPP, does the chosen VPP provider support the exact inverter and battery, and does the customer meet the rules for the plan or incentive being considered? Passing one check does not automatically pass the others.
What is a VPP?
A virtual power plant connects many batteries so they can work together. The VPP operator may charge or discharge participating batteries at selected times to support the grid. In return, customers may receive bill credits, higher export payments, an upfront incentive or another financial benefit.
Check 1: is the system technically VPP-capable?
Many new grid-connected batteries are designed so they can communicate with an external service. This normally requires compatible control hardware or software and a reliable internet connection.
Technical capability is only the first step. It does not mean every VPP company supports that model.
Check 2: does the provider support the exact equipment?
VPP providers maintain their own compatibility lists. These lists can be model-specific and can change as new integrations are approved.
For example, Origin’s current compatibility list includes a range of GoodWe ETA-G20 three-phase inverter models and the GoodWe ESA battery series. That is useful, but I still confirm the exact model before relying on it in a proposal because compatibility lists can change.
Check 3: does the customer meet the plan or incentive rules?
A compatible battery may still need the right electricity retailer, smart meter, solar system, internet connection, location and account type. Some VPP plans also have rules about life-support equipment or participation in another VPP.
Government incentives add another layer. The incentive rules are not the same thing as the retailer’s equipment list.
Current NSW VPP incentive
As checked on 17 August 2026, the NSW Government says households and small businesses may be eligible for an incentive when connecting an eligible battery to a participating VPP. Batteries over 2 kWh and up to 50 kWh can be eligible, while the incentive calculation applies to capacity made available to the grid up to 28 kWh.
The actual dollar amount can vary by VPP provider and contract. The NSW Government also says customers may need to change retailer because not every retailer works with every VPP.
The NSW VPP incentive can be combined with the Australian Government’s Cheaper Home Batteries Program where the requirements of both programs are met.
Why this matters
You might find a battery on an approved government product list and assume it will work with your preferred VPP. That is not enough. The VPP provider still needs to support the battery and inverter combination, and the customer still needs to meet the provider and incentive rules.
Questions I would check before choosing a VPP
- Is the exact inverter model supported?
- Is the exact battery model or series supported?
- Do I need to move to a specific electricity plan?
- Can I stay with my current retailer?
- How much battery capacity can the VPP use?
- Is a minimum backup reserve protected?
- How often can the VPP discharge the battery?
- What payments, credits or sign-up benefits apply?
- Are there exit fees or a minimum contract period?
- Does VPP cycling affect the battery warranty?
- Does a state incentive have separate eligibility rules?
Do not choose the battery from the incentive alone
A VPP payment can improve the economics, but the battery still needs to suit the property. I would first check solar surplus, later grid use, tariff, battery size, backup goals and compatibility. The VPP should improve a suitable system, not be the only reason the system is selected.
