EDF & Valeo – Vehicule to Blockchain
Blockchain energy trading platform with Vehicle to Grid capabilities
1. Project Summary
Name of company: EDF & Valeo
Sector: Energy / Automobile
Project Period: May – November 2019
Mission of the project:
The business goal of this project is twofold: - To demonstrate the advantages of vehicle to grid (i.e. V2G) capabilities in the context of collective self-consumption where local participants can trade energy through a decentralized market place. - To investigate the impact of an energy aggregator on the local energy market place.
- A physical demonstrator has been built to illustrate the blockchain based P2P trading solution on a small locality equipped with self-production means and an electric car. This allows to target a wide range of audience with instructive and communicative purposes to foster the development of this technology.
- An agent-based framework has been developed to simulate the performance of the system with configurable parameters to study the macro-behavior of the system. This allows, amongst other analysis, to investigate the impact of an energy aggregator on the local energy market place.
Xdev technologies: Business Partners Platform Framework / ChainDeploy
BC technologies: Parity (Ethereum)
Maturity Level: Proof of Concept

Summary of the project
In the context of aPeer-to-Peer energy marketplace enabling local self-consumption, the introduction of electric vehicles capable to discharge their batteries could be beneficial on many aspects and enable new capabilities. To raise public awareness on this concepts of self-consumption, we have built a physical demonstrator simulating a small locality and interacting on the Blockchain. In addition, we have developed a proprietary simulation tools to conduct in-depth experiments of this solution in a virtual environment. This allows to assess the economic and social needs to deploy such an infrastructure.
Growing concern over environmental issues has pushed the energy market towards green energy and decentralized production. Consumers equipped with local production means (i.e.prosumers) such as solar panels or wind turbines, are now able to consume and sell their self-produced energy. New market approaches are being developed to allow the redistribution and pricing of this renewable energy within a community. In a previous project1, we have demonstrated how a blockchain based solution can enable Peer-to-Peer trading of energy, based on a automated auction process ruled by a smart contract.
However, renewable energy as well as consumer consumption are variable by nature, and sometimes do not match. For example, energy production often peaks around 1pm, due to massive adoption of solar panels in households. However, consumption is often low at this time of the day, and peaks during the evening. With the emergence of new Vehicle-to-Grid technologies, Electric Vehicles have appeared as a solution to store,transport and re-distribute energy to smooth the energy balance and increase the autonomy of the locality.
The objective of this study is to analyse the impact of Vehicle-to-Grid capabilities in a local energy marketplace.
Peer-to-peer energy market places are a first step towards effective re-allocation of energy, yet it does have limitations :
Our solution integrates a Vehicle-to-Blockchain capability to a decentralised local energy market place. We have demonstrated that this new capability smooths the production / consumption balance of prosumer communities, by adding a different consumer / producer profile to the market place.
Indeed, economic incentives encourages behaviours that are beneficial to all:
- Electric Vehicle owners are encouraged to charge their vehicle at night when energy demand is cheaper, then giving the energy accumulated in the car back to the grid during peak hours for higher prices. This behaviour smoothes the energy balance of the community.
- Electric Vehicle owners are encouraged to decharge in localities with low supply of green energy and hence higher price.. This means green energy can be transported, and areas not equipped with green energy production can enjoy green energy produced in neighboring localities through their vehicles.
As a result, the enlarged grid is beneficial to all :
In a nutshell, this solution brings cleaner power, lower energy costs and greater stability.
In the course of developing the aforementioned system, several challenges have been tackled:
- V2G and local marketplace promotion: through a pedagogical and playful physical demonstrator, we highlight the benefits of such capabilities for end-users, the locality and the environment.
- Multi-agent simulation to assess economic viability: in order to simulate the locality with its households and Electric Vehicles, we have implemented a simulator based on the multi-agent paradigm that is suited to distributed architectures such as a Blockchain. The simulations enables to perform a sensibility analysis of the economical gain provided by the solution in different settings (e.g. vary the number of EVs, their battery capacity, the number of households, the climate etc.).
