Three simple moves
Save. Event. Earn.
GridPiggy spots an opportunity.
When energy prices or grid conditions create an opportunity, GridPiggy can run an Event using eligible battery flexibility.
The value goes into your PiggyBank.
The additional value created during an Event is recorded in your PiggyBank, where you can see what your battery has earned.
Self-consumption first. GridPiggy Events second. Extra value for you.
Your home has priority
Your battery’s first job
Your battery’s first job
is saving you money.
GridPiggy does not forget why you bought a battery.
Before looking for earning opportunities, your FoxESS battery supports your home — storing your solar energy and reducing the electricity you need to buy from the grid.
Only eligible battery flexibility is considered for GridPiggy Events.
- Use more of your own solar
- Buy less energy from the grid
- Keep your household energy needs first
- Unlock additional value when conditions are right
Save first means exactly that.
Smart moments. Real value.
What is a GridPiggy Event?
A GridPiggy Event is a short period when your battery can respond to an energy opportunity.
That could mean charging when grid energy is cheaper, avoiding higher-cost electricity later, or exporting eligible stored energy when the grid values it more.
GridPiggy identifies the moment. Your compatible FoxESS battery responds. The value created is added to your PiggyBank.
Store energy while it is cheap.
Grid energy becomes cheaper. Your battery charges at the lower price and holds that energy for a more valuable time.
More affordable energy stored for later.
Release it when the grid needs it.
The grid needs more energy and export value rises. Eligible stored energy is exported during the Event.
The additional value is added to your PiggyBank.
Event availability, operation and value vary by location, electricity plan, energy-market conditions and system eligibility.
Where your battery’s value adds up
Meet your PiggyBank.
PiggyBank is the home for the additional value your FoxESS battery creates through GridPiggy Events.
Each completed Event adds to your story: what happened, how your battery responded and what value it generated.
Simple enough to understand at a glance. Detailed enough to show how your battery is working harder.
Your battery does the work. PiggyBank keeps the score.

The detail
Frequently
Frequently
asked questions.
What is confirmed today, and what is still to be confirmed — in plain language.
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 battery responds within the
program settings you have agreed to.
PiggyBank is where the additional value created by your battery during GridPiggy Events
is recorded, so you can see what each Event was worth. It is not a bank account, and the
PiggyBank interfaces shown on this site are concept previews — settlement and
payment options are to be confirmed.
Yes. Self-consumption comes first: your 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.
No. Registration records your interest and basic system information only. It does not
give GridPiggy remote access to your battery and does not activate any control
functions.
No. Event availability and value depend on your location, electricity plan,
energy-market conditions and system eligibility. Any figures shown on this site are
illustrative examples, not projections of what a particular household would earn.
To be confirmed. GridPiggy is built around existing FoxESS batteries and inverters, and
the supported configurations are being finalised. Registering your model and inverter
details is what tells us which systems to prioritise.
