    Renault and Publicis Amsterdam were tasked with demonstrating the practical value of electric mobility beyond personal transport. The client needed to address the growing energy grid instability in Utrecht caused by sustainable energy adoption. The goal was to prove that electric vehicles could act as a solution to urban infrastructure challenges, positioning Renault as a leader in the energy transition for city residents.

    Creative Idea

    The car stopped being a vehicle and became a city-wide power plant.

    Renault transformed its electric fleet into a decentralized power plant, using bidirectional charging to stabilize Utrecht's overloaded energy grid. By turning cars into mobile batteries, the campaign solved a critical infrastructure crisis while proving the utility of sustainable mobility.

    Turning Shared Cars Into Urban Batteries

    Scaling From Pilot To Powerhouse


    The project evolved rapidly from a localized experiment into a critical piece of Dutch infrastructure. Starting with a modest fleet of 50 Renault 5 E-Tech vehicles, the initiative proved that bidirectional charging could effectively mitigate grid strain. By the one-year anniversary in June 2026, the fleet had scaled to 350 vehicles across Utrecht and Eindhoven. This expansion achieved a significant technical milestone: 2 MW of grid discharge capacity, providing enough energy to support 2,000 households during peak evening hours.

    Technical Orchestration Behind The Scenes


    The production of the case study required close coordination between Publicis Amsterdam and 10/10 Amsterdam to capture the complex interplay between software and hardware. The project relied on the Last Mile Solutions platform, which managed over 120,000 charging transactions to ensure the grid remained balanced. Robin Berg, CEO of We Drive Solar, was instrumental in the technical deployment, designing the bidirectional posts that allowed the cars to function as mobile energy storage units.

    Long Term Grid Resilience


    The campaign moved beyond traditional advertising by integrating into the city's energy strategy. The data collected during the first five months showed a 300 kW reduction in evening peak demand, with each vehicle contributing an average of 1,300 kWh back to the network. Looking ahead, the project aims to reach a 500-car fleet, which is projected to provide 10% of the total flexibility required to stabilize the Utrecht regional grid. This shift positions Renault not just as an automotive manufacturer, but as a primary stakeholder in the transition to renewable urban energy systems.

    Company

    Renault leveraged its advanced V2G bidirectional charging technology to turn electric vehicles into mobile, grid-stabilizing energy storage units.

    Category

    Automotive brands typically market performance, luxury, or status, ignoring the role of vehicles as active components of urban energy infrastructure.

    Customer

    Residents felt anxiety regarding grid instability and the environmental impact of rapid electrification, seeking solutions that provide tangible community benefits.

    Culture

    The global energy transition and the urgent need for sustainable, flexible power solutions made bidirectional charging a highly relevant, timely innovation.

    Strategy:

    Solve systemic infrastructure failures by repurposing consumer products into essential public utilities.

    Results

    The campaign successfully deployed a fleet of 500 Renault 5s equipped with V2G technology. This initiative turned cars into mobile power sources, capable of storing and returning megawatts of clean energy to stabilize the grid for 190,000 households. The project achieved 6,100 discharging cycles, returning 37,000 kWh of electricity back to the grid. The technology is set to expand to 4 more cities.
