The battery will store renewable energy – to be used later by you or by your local grid when it’s needed most.
Get money off your energy bills
With a home battery, you could save up to £90/year2 because you’ll be using more of your own energy.
Develop Home Energy Storage with us
As one of the first to use this technology, your feedback will help shape the future of home batteries.

To take part in the trial, you’ll need to switch your energy to OVO. In return, we’ll install a 4.1kWh Powervault Battery worth £5000, absolutely free.
What does the trial involve?
We have been working with your local DNO (distribution network operator) to identify particular areas where the network would benefit from having additional flexibility on the customer's side in the form of home energy storage. In addition to increasing the household self-sufficiency by enabling use of more electricity generated from the solar panels, batteries can form a critical part in supporting low voltage (LV) networks at peak times through reducing peak demand of the household and exporting back to the network if called up by the network operator.
During some specific events throughout the year your battery may be used to support the local network. You will be able to track these actions via the online Powervault portal, which comes with your Powervault battery.
Between October and March
At times when your local network is under constraint or at risk of fault, part of your Powervault battery capacity may be reserved and used to support your local network. Essentially, at times when it’s needed most, we will export the energy stored in your battery back to the grid.
During this period, there may be times where we top up the solar energy stored in your battery with energy from the grid. This is to ensure that there is enough energy available to provide the support mentioned above to your local network.
You may see your energy consumption rise when we need to top up your battery with energy from the grid. There is a risk that when this happens, your energy bill may increase. However, over the course of the trial you will be better off and could save up to £902 on your energy bill per year.
Between April and September
Your battery will predominantly be used for your home - storing energy from your solar panels to be used within your home when the sun isn’t shining. There may be occasions where we are testing how else your battery can be used to support the wider electric grid to integrate more renewable generation - so you really are becoming part of the future UK energy network.
Powervault is a British company, headquartered in London. It designs and manufactures smart energy storage systems for the home, which store free solar energy and cheap electricity from the grid to reduce household energy bills and increase energy efficiency.

A Powervault system can be typically installed in a single visit, although this will depend on each property. The Certified Installer will be able to confirm how long the install will take after they have completed a survey.
The Powervault battery comes with a market-leading warranty of 10 years, and Powervault will either repair the defective product without charge for parts and labour, or will provide a replacement in exchange for the defective product. You can find more warranty information here: http://www.powervault.co.uk/technical/warranty/
If you’re planning on moving home, give us a call on 0330 102 7423 and we’ll look into possible options. We might be able to remove your battery and look to re-install at your new property once it’s on supply with OVO.
If you leave OVO within the two year trial period, we’ll arrange to come and remove the battery. After the two year trial period, you’re free to leave OVO and your battery will continue to function as normal.
The Powervault customer portal provides customers with a platform from which to monitor their energy use and optimise their charging schedules. Customers can access information about the present and historical performance of their system and use the smart tariff controller on the portal to optimise the charging of their battery against ‘smart’ time-of-day tariffs.

1. Register your interest
Register your interest via our online form. Once received, we'll be able to get a general overview of your eligibility for a battery installation.
2. Terms & Conditions
If selected as a participant, you’ll be provided with the Terms and Conditions of the trial, and we’ll give further detail the next steps to complete your install.
3. Switch to OVO
If you're not already an OVO customer, we'll ask you to start your switch. You can sign up to any of our single-rate, fixed term tariffs.
4. Technical Survey
A technical survey will be undertaken to ensure that your home setup meets the requirements for the battery installation.
5. Agree an installation date
Once all of the technical checks have taken place we’ll arrange an installation date with you.
6. Battery Installation
An engineer from our installation partners will come and install your charger, on a day that suits you best. You'll get access to the PowerVault control functions and can use your new device!
Terms & Conditions
Savings based on the estimated annual savings for a customer with an annual electricity usage of 5,000 kWh, 5kWp rooftop PV and a 4.1 kWh/3.3kW Powervault battery. Some battery capacity will be used for supporting the local grid. Comparison made against the same user without a battery. Savings are an estimate only and your actual costs will vary according to your region and usage.
