How much CO2 emissions have been prevented by the V2G trial?
Will OVO offer time of use tariffs similar to Octopus?
What is likely to be the future of the V2G chargers once the trial has ended and will there be the option to control them without the Kaluza platform? (Will we have direct control over them if we changed supplier for example)
Is it possible for Ovo to be more transparent (include KWh figures) with export payments?
Is an API or local access via MQTT (or some other protocol) going to happen for V2G and smart charger? (Also useful for errors and faults)
Is Kaluza planning an integrated energy system for domestic users (bringing solar, V2G / V2H, battery storage, heat pumps, heating etc together on one platform) with integration with existing hardware and tariffs that make financial sense for consumers to want?
Will there be an IOS / Android app for Kaluza?
Will it be possible to have V2G and Smart charger (or multiple smart chargers) controlled from a single account?
How does Kaluza / OVO make profit from V2G and is this commercially viable once the trial has ended?
Is OVO working with DNO’s and Government to facilitate mass roll out of V2G in the future? (It seems currently there is a very mixed response from different DNO’s)
Thank you for trying to change the future for the better.

This is a huge one, thanks for posting this
I don't have the data available from the beginning of the trial, but since the beginning of 2020, the 322 V2Gs connected to the platform saved 16.41 tonnes of CO₂ by time shifting charging.
Time of use tariffs
Within OVO we constantly review our tariffs in relation to the competition and market trends. Time of use & type of use tariffs are an area of investigation for OVO at the moment but there is no timeline for the launch of a commercial proposition yet. Watch this space!
Is it possible for OVO to be more transparent (include KWh figures) with export payments?
As this is what we’d call a ‘technical feasbility trail’, there are limitations to what insights we can offer trialists. However we recognise the value of providing kWh info to trialists and will review it as part of the trial review phase
We don't have any commercial framework in place for offering our APIs as a SaaS (software as a service) product. At the moment we only offer our APIs to selected partners, but this may change in the future as we scale. I'd be very interested to know what your use case would be though
Integrated Energy System
An integrated energy system is part of our long term vision, see our Flex platform website for more info.
We debated for a long time about whether to build a progressive web app (PWA) or a native app back when we started in 2017. Having had a lot of combined experience developing native, hybrid and web apps, we decided to go with a PWA for a number of reasons:
- It's much quicker and easier to deploy a new version of the app for us and for you
- All users are always on the latest version (which reduces the complexity of potential support issues "I'm on version 5.1.1" "Oh, that version doesn't support feature X")
- It's works on iOS, Android, Windows, Symbian, Mac, Linux, etc. out of the box with little additional effort on our part
- The device hardware and functionality that web apps can access like the camera, fingerprint sensor, location awareness, notifications, etc. are continually expanding and improving
- There's no overhead of publishing to an app store (costs, complicated release processes, third party review time, opaque rules, etc.)
That said, we acknowledge Apple, Google and Microsoft have trained several generations to expect apps to live in app stores. Native apps still have greater access and potency than their web based brethren (for the moment) and Apple certainly treats web apps as second class citizens in its ecosystem. In contrast, putting our current app onto the Google Play Store is relatively easy, but we didn't think it was fair to differentiate our offering like that, especially given the majority of our users are on iOS.
I mentioned in my response to
Multiple Device Support
This is also on our radar. We know it's causing pain for some of you, particularly if you have a V2G. It's not something we're planning on working on in 2020, but we may look at in the future.
The V2G trial is and always was a technical feasibility trial. The intention was never to make a profit, but determine if bidirectional charging could support grid flexibility. Part of the trial review will be to determine if the device could be incorporated into a revenue generating proposition.
A major part of our programme is working closely with government to achieve a shared understanding of what a future where local grid balancing is the norm looks like. By its very nature this involves ongoing discussions with DNOs and National Grid.
Becoming the Standard
Our founder Stephen Fitzpatrick expresses this most eloquently when he says his vision for OVO is to get to a point where it's considered Critical National Infrastructure. We would very much like to become the de facto standard and are pursuing a number of partnerships with this in mind.
