Project Sciurus

Case Study

The Challenge

Project Sciurus was a hugely ambitions, UK based V2G project, that ran between 2018 and 2021 and combined experts in energy, transport and infrastructure.

The project developed a real-world domestic solution for V2G, installed V2G in hundreds of homes across the UK and smartly controlled its operation to reduce cost and provide services to the grid.

Further the project was to demonstrate the business case for domestic V2G.

The Development

Cenex analysed the data coming in from all the chargepoints installed as part of the project. This data was used to understand how participants were using their cars and the chargepoints.

We also derived customer archetypes for the participants to analyse the business case for each and identify which ones were best for a V2G proposition; annual revenue for each V2G customer archetype and with each V2G revenue stream was calculated.

Further, Cenex disseminated the analysis and learnings from the project through a white paper, public report, webinar and podcast.

The Results

The project had some significant achievements, including:

  • 320 V2G units installed in real homes across the UK
  • The technology and business cases to prove the economic, environmental and societal value of V2G.
  • The design and manufacture by Indra of a wall mounted domestic V2G chargepoint that was CHADEMO and CE certified, G98 and G99 type tested, achieving vastly reduced unit costs.
  • Development by Kaluza of an ‘Intelligent Energy Platform’ that monitors and calculates the best charging schedules to follow based on the customer needs, energy wholesale and balancing markets.
  • Development of a Customer App that allowed customers to monitor car import and export and set their charging preferences.

The project also made some key findings:

  • The V2G units were able to create between £230 and £300 of value per year through the spot electricity market via the Kaluza platform. When combined with flexibility services this could grow to £500 per year
  • 75% of participants said that they plugged in their EV after every trip. This is much higher than most EV users, who typically plug in to a home chargepoint about once every three days.

Use of the V2G technology during the trial alleviated most of the participants concerns
