OVO Vehicle-to-Grid Trial

The OVO V2G Charger stores electricity in your Nissan electric vehicle battery when it’s cheaper and more likely to have been produced by renewable sources, then sells energy back to the grid when it’s in demand.

Sign up to OVO Energy, join the trial and you’ll get a groundbreaking charger for free. You will also get a £75 credit on your first OVO Energy bill and a payment of up to 30p per kWh of energy exported back to the grid.

Combining your Nissan EV and our V2G Charger could save you up to £570 a year

Get a free charger, and much more

On your first bill following your install, you’ll receive a £75 credit as a thank you for joining the OVO V2G trial.

Following this, each month you’ll get a credit for all the energy you have exported back to the grid.

You’ll see this on your energy bill as a ‘Vehicle-to-grid Trial Export Credit’.


OVO Vehicle-to-grid charger

The V2G Charger stores electricity in your Nissan LEAF battery when it’s cheaper and more likely to have been produced by renewable sources, then sells energy back to the grid when it’s in demand, which might even save you enough to charge your car for free.

Building a better grid for everyone

The grid is the UK’s energy network, connecting millions of homes to thermal power stations and renewable energy sources. And it’s getting greener. But green energy is intermittent by nature. We can’t switch it on when demand is high. And without flexibility, adding more renewables to the grid is complicated and expensive.

For a flexible, balanced grid, we need more control and that starts on your driveway.

How it works

Your charger will handle most of the clever stuff itself – all you need to do is tell the Kaluza web-app when you need your car to be ready and a minimum charge level. Then, just plug in your car when you get home. The Kaluza intelligent energy platform will then decide when to charge your battery and when to export to the grid – all while having your car ready for when you need it.

Tell the Kaluza web-app when you need to use your car and your chosen minimum charge level.
Plug your car in to your charger whenevr you’re at home.
The V2G charger will charg your car when demand on the grid is low, and export when demand is high (working around the charging schedule you’ve set in the web-app)
Anything exported that your house doesn’t use, OVO will sell back to the grid. You’ll see the money you’ve saved on your monthly statement.

Frequently Asked Questions

How do I know if I'm eligible for the trial?

You’ll need to own or lease a Nissan LEAF, or a Nissan e-NV200.

You’ll also need to be an OVO energy customer on any of our fixed term plans. You’ll also need to have a smart meter installed and have your data sharing preferences set to half hourly. You also need a suitable space to install the charger, and unfortunately we can’t support people on Economy 7 tariffs.

Once on the trial, to remain eligible you’ll need to make sure your data preferences are kept as half hourly and that the V2G charger is the main method of charging your electric vehicle. If not, your charger may be removed.

I'm not an OVO customer, can I still take part?

The trial is for OVO customers only. If you’re not an OVO customer, but you’re willing to switch - great! Register your interest here, and let us know you’re prepared to switch. We’ll then let you know when to switch as part of the sign-up journey.

I am on a dual rate (Economy 7) tariff, can I still take part?

At this stage, the trial is only for people on a single-rate tariff. If you are on a dual-rate tariff and want to be part of the trial, let us know and we can get you switched over.

Why is the V2G Charger only available for Nissan electric vehicle drivers?

The LEAF, and the e-NV200 are currently the only vehicles we will be supporting as part of our trial. So you’ll need to drive one to take part.

Why is my Nissan EV not supported?

Our agreement with Nissan currently only guarantees warranty coverage for the following:

Nissan LEAF - 30kWh, 40kWh, 62kWh Nissan e-NV200 - 40kWh If you have a 24kWh Nissan LEAF and your existing warranty period has expired, you are also eligible to join the trial.

However, if your battery capacity is 24kWh and you are still in your warranty period, we are working on an agreement with Nissan that will allow you to take part in the trial.

Will it effect my Nissan EV battery Warranty?

We are working closely with Nissan to ensure that no battery degradation is caused by V2G charging beyond what would be expected from normal charging using a standard EV home charge point. We continue to work with Nissan to make sure that during our trial, your existing warranty will remain unaffected.

If you have a 30kWh, 40kWh, or 62kWh Nissan electric vehicle, your existing battery warranty remains unaffected by your participation on the trial.

If you have a 24kWh LEAF that is already out of warranty, you are also eligible to join the trial.

If you have a 24kWh and are still in your warranty period, we are still working with Nissan to confirm that you can take part and hope to have more news soon.

How long does the trial last?

The trial will last for 24 months from the date your charger is installed. You’ll need to remain an OVO customer throughout the duration of the trial on any OVO plan. During the trial we’ll ask you for regular feedback to help us develop and refine the product for the future.

As it is a trial, the terms may be subject to change. At worst, if we need to change or cancel the trial, we will let you know 30 days before doing so.

Is the V2G Charger mine to keep after the trial?

At the end of the trial, you have two options:

  • You can keep the charger and have the ownership of it transferred to you. You will be required to pay a fee of 1p for administrative purposes.
  • You can have the charger removed for free

How do I know if my property is suitable?

To install the V2G charger you’ll need off-street parking and a wall we can attach the charger to. We’ll assess your property as part of the installation process, and confirm whether we can install a charger.

We will support any standard installs for free as part of the trial. If it’s a very complex install, we’ll provide you with a no-obligation quote for the work, or advise you that we can’t install at your house during the trial. Either way, we’ll make sure you’re 100% happy with the detail of the install process before we start any work.

I'm on the trial - when will I receive my export credits?

You’ll see your export credits as a line item on your regular statement. The amount shown will be for the entire calendar month previous.

For example, if you get your statement from us on the 10th of each month, on the 10th July you’ll receive your export credits for June 1st - June 30th. You’ll see July’s credits in August, and so on.

Why is my export credit lower if I have solar?

If you have solar panels, we will be paying you for all of your exports, not just those from your vehicle-to-grid charger. As we’ll be paying you at a rate of your 26p per kWh, you will be receiving significantly more than your current deemed export payment.
