Everything the main pages keep short, answered properly here — including the parts that are still to be confirmed.
GridPiggy today
What is live,
What is live,
what is not.
What you can do today, what is still being built, and what is genuinely undecided.
Registration is open now. The connected service — GridPiggy Events, battery response and
PiggyBank — is still being built, and rollout dates will be announced to registered owners
first.
To be confirmed. GridPiggy is built around existing FoxESS batteries and inverters, and the
supported configurations are being finalised. Telling us your battery model, capacity and
inverter at registration is what decides which systems are prioritised.
No. Registration records your interest and basic system information only. It does not give
GridPiggy remote access to your battery, does not activate control functions and does not
enrol you in a program.
To be confirmed. The intent is to work with the FoxESS system already installed at your home
rather than replace it. If a particular configuration turns out to need anything extra, that
will be set out clearly before you are asked to decide anything.
To be confirmed. Initial availability depends on energy-market and program arrangements that
vary by region. Your postcode at registration is what tells us where FoxESS owners are
concentrated, which is a direct input into that decision.
Events and PiggyBank
How the value
How the value
is created.
What an Event is, how the value is handled and where the honest gaps still are.
An Event is a short period when your battery responds to an energy opportunity — charging
while grid energy is cheaper, or exporting eligible stored energy when the grid values it more.
GridPiggy identifies the moment; your compatible FoxESS battery responds within the program
settings you have agreed to.
No. Event availability, operation and value vary by location, electricity plan, energy-market
conditions and system eligibility. Nothing on this site is a promise of savings or earnings, and
every figure shown is an illustrative example rather than a projection for any particular home.
To be confirmed. The method will depend on the Event type, the energy your battery charged or
exported, the market or program value at the time and the agreed owner share. The calculation
will be published before any Event runs.
PiggyBank is where the additional value your battery creates during GridPiggy Events is
recorded: what happened, how your battery responded and what the Event was worth. It sits on
top of the savings your battery already makes at home.
No. PiggyBank is not a bank account, deposit product or investment, and GridPiggy is not a bank
and does not provide financial products. It is a record of Event value, nothing more.
To be confirmed. Settlement and payment arrangements — including whether value is paid
out, credited or applied another way — have not been finalised, and no withdrawal
functionality exists today. Every PiggyBank interface on this site is a concept preview with
illustrative figures.
Your home and the Founding 50
Your household
Your household
comes first.
The priority order in your home, and what founding membership actually means.
Yes. Self-consumption comes first: your FoxESS battery supports your home before any Event is
considered, and only eligible battery flexibility is used. Final operating parameters are set
out in the program terms before anything is activated.
The Founding 50 is a limited group of FoxESS owners who will be first in line for the GridPiggy
experience: founding member status, priority onboarding, first access to eligible Events and
early access to PiggyBank. Applications are open now, and founding status cannot be added later.
Membership is limited to 50 accepted owners and is subject to the Founding 50 terms.

Still to be confirmed.
Two lists. Anything that moves from the right column to the left will be announced to registered owners first.
What is not settled yet
- Rollout dates for GridPiggy Events.
- Which system configurations are compatible.
- Initial locations and eligibility rules.
- How Event value is calculated and shared.
- PiggyBank settlement and payment options.
Nothing on this page is a promise of savings or earnings. Outcomes depend on household consumption, solar generation, battery size, electricity tariff, system configuration, location and program availability. Every dashboard, balance and Event interface shown on this site is a concept preview with illustrative figures.
