Kaluza leading the way with domestic Vehicle-to-Grid (V2G) optimisation

Posted: 15 Jul 2019

The world's largest domestic Vehicle
to-Grid project






2 year project (2018-2020)


£5m project with £3m funding from Innovate UK


Validate the technical and commercial potential for a domestic V2G charging solution


1000 V2G Units installed and connected to Kaluza platform

Project Sciurus is part of the UK’s Vehicle-to-Grid competition, funded by the Office for Low Emission Vehicles (OLEV) and the Department for Business Energy and Industrial Strategy (BEIS), in partnership with Innovate UK.

Vehicle-to-Grid (V2G) charging will enable electric car owners to save on their transport and energy bills by buying energy at times of low cost and selling unused energy back to the grid during peak times.

In turn, development of a smart grid around electric vehicles, smart charge points and other connected home devices entails considerable cost savings for grid operators. Instead of spending large sums on unsustainable network reinforcements, operators can tap into the inherent flexibility of millions of electric vehicles bought in the UK over the next decade, creating a giant battery at the residential level. Through intelligently managing charging behaviours via V2G the UK can turn electric, supply and demand can be efficiently balanced, accelerating decarbonisation.

The use of Intelligent charging of electric vehicles


Project Sciurus is the world’s largest domestic V2G roll out. 1,000 chargers will be supplied and installed, at no cost to the customer, with the aim to validate the technical and commercial potential for a domestic V2G charging solution capable of providing flexibility services to electricity networks and bring added benefits to the device user.

We are delighted to win the Innovate UK grant and collaborate with such innovative partners to develop this new and exciting technology that will help balance the grid. By developing vehicle-to-grid technology we’re taking smart charging one step further, enabling drivers of electric vehicles to sell energy back to the grid at peak times. This in turn will help to balance the grid and maximise the use of renewables in the energy system.

Kaluza Optimisation

The first project of its kind, all hardware and software components are developed from scratch. Indra Renewable Technologies, Kaluza’s manufacturing partners, have built a revolutionary wall-mounted domestic V2G charger. Integrated with Kaluza intelligence, the platform receives live signals from the grid and optimises charging so that energy is bought at times when cost and carbon levels are low while ensuring that vehicles are ready by the time scheduled by the EV drivers.



As the project’s energy supplier partner, OVO Energy, has developed innovative customer propositions in tandem with their bespoke electric vehicle tariff ‘EV Everywhere’ that encourages early adopters to participate in the trial. To take part, charger recipients must drive a Nissan Leaf and be or become an OVO Energy customer.

OVO Energy will pay customers 6p per kwh sold back to the grid, saving some customers approximately £300 a year on their energy bill. potentially allowing them to drive their car for free. With Kaluza integrated across 1,000 V2G units, grid operators can harness new flexibility to offset demand peaks and generate more renewable energy that can be dynamically stored across a more distributed ecosystem.

Results of the project will be published on completion in 2020.
