Virtual power plant

Get paid for the capacity sitting idle in your battery.

Most batteries spend a good part of the year only half used. A virtual power plant pays you for that spare capacity, and that income can go towards the one line on your bill solar and storage cannot touch on their own: the daily supply charge.

What a VPP actually does

It pays for capacity you were not using

Your battery is sized for your worst evenings, which means on an ordinary day a good portion of it sits idle. A VPP puts that spare capacity to work and pays you for it, without changing how the battery serves your own home first.

That income can cancel out your supply charge

Solar and storage cut the energy you buy, but the daily supply charge is fixed and lands whether you use a kilowatt or not. It is the one part of the bill you cannot generate your way out of. VPP income is the mechanism that can offset it.

You keep your electricity retailer

Joining does not mean switching providers or signing up to a plan you did not choose. You stay with whoever you are with, and keep the freedom to change later.

Every battery we install is VPP compatible

We do not sell storage that cannot participate. Whichever battery suits your home, the option is there whether you take it up now, later, or never.

Your warranty is unaffected

Participation is within the operating limits the manufacturer warrants. Taking part does not put your cover at risk.

It is optional, and reversible

You do not have to join, and you are not locked in if you do. We will walk you through the terms before you decide rather than after.

How it works

How it works

  1. Check it suits you

    We look at your battery, your usage and your tariff, and tell you honestly whether the numbers are worth having.

  2. We handle the setup

    Enrolment and configuration are done for you. Nothing changes about how you use power day to day.

  3. Watch the credits arrive

    Track participation and earnings in the app, and tell us if it is not paying what you expected.

Frequently asked questions

Will it leave me without power?

No. Your own home is served first, always. A VPP only ever draws on capacity beyond what your household needs.

Do I have to change electricity retailers?

No. That is deliberate on our part. Some VPP programs tie you to one provider; we would rather you kept the freedom to shop around.

Does it cost anything to join?

No upfront cost. You are credited for taking part.

Will it wear my battery out faster?

Cycling contributes to degradation, which is why warranties are written around throughput. Participation stays inside those limits and does not affect your cover.

What is the difference between this and a feed-in tariff?

A feed-in tariff pays a flat rate for anything you export, whenever you export it, and those rates have fallen a long way. A VPP pays for capacity released when the grid genuinely needs it, which is worth considerably more.

Can I leave later?

Yes. Terms vary by program, including any notice period, and we go through them before you enrol.
