Utilities as the Hidden Growth Engine Behind Peer-to-Peer EV Charging
Peer-to-peer EV charging is often framed as a mobility innovation, but its real long-term potential reaches much further. For utilities, energy retailers and infrastructure leaders, community charging models open a path to expand EV access, deepen customer relationships and create new digital revenue streams—without relying only on costly, net-new charging buildouts. When underused private chargers are connected through intelligent digital platforms, charging stops being just a transaction. It becomes a networked service layer that can improve grid visibility, support load balancing, enable off-peak incentives and deliver a more seamless customer experience across the EV journey.
That is what makes Renault’s Plug Inn such an important proof point. Built with Publicis Sapient, Plug Inn showed how a peer-to-peer model can connect EV drivers to home and business charging stations, helping address range anxiety by unlocking existing infrastructure rather than waiting for the public network alone to catch up. In its first month, the platform reached 25,000 downloads, more than 8,000 users and 1,000 registered charging stations. It also demonstrated that shared charging can support a profitable service-based model while contributing to a more sustainable mobility ecosystem.
Why utilities should care about community charging
As EV adoption grows, utilities face both pressure and opportunity. Charging demand introduces new complexity into the grid, but it also creates a new arena for customer engagement and service innovation. Utilities are no longer limited to supplying kilowatt-hours. They can play a central role in helping customers navigate EV ownership, charging access, pricing and energy optimization.
Peer-to-peer charging is especially compelling because it expands the available charging network quickly by making better use of assets that already exist. Thousands of private chargers sit idle for much of the day across homes and businesses. A digital platform can turn those underused assets into part of a broader charging ecosystem. That reduces the need to fund every new charging point from scratch while improving convenience for drivers in residential areas, underserved neighborhoods and regions where public infrastructure is still sparse.
For utilities, that means faster market participation with a lighter infrastructure burden. Instead of focusing only on building, owning and operating every charging location, they can help orchestrate a distributed network of chargers, hosts and drivers. In doing so, they gain access to usage signals that can inform grid planning, customer offers and future service development.
From charging access to grid intelligence
The real utility opportunity begins once a charging network becomes digital, connected and data rich. Every charging session creates insight into when, where and how energy is being consumed. When this information is brought together across customer, charging and grid systems, utilities gain a stronger view of demand patterns and can respond more intelligently.
That enables several high-value use cases:
- Improved grid visibility: Charging data helps utilities identify where demand is growing, where capacity may come under pressure and where investment will have the greatest impact.
- Off-peak incentives: Utilities can encourage charging when demand is lower, helping customers save while smoothing consumption across the network.
- Load balancing: Better visibility into charging behavior supports managed charging strategies that reduce spikes and avoid unnecessary strain on the grid.
- Smarter planning: Data from distributed chargers can help utilities determine where public charging, grid upgrades or new partnerships are most needed.
This is where peer-to-peer charging becomes more than a convenience play. It becomes part of a broader digital operating model for electrification. Utilities that move early can use these data flows to improve reliability, avoid inefficient overbuilding and create more adaptive energy services.
A better EV customer journey for utilities
The shift to EVs has exposed how fragmented the customer journey can be. Drivers must navigate vehicle selection, charger installation, public charging access, tariffs, pricing and ongoing usage across multiple disconnected providers. Utilities have an opportunity to reduce that friction and become a trusted guide across the full experience.
Community charging can strengthen that role. A utility-enabled platform can help customers discover charging options, understand costs, access transparent pricing and receive tailored guidance on when and where to charge. With the right digital foundation, the experience can evolve from basic access to more personalized services such as dynamic incentives, battery-related insights, proactive alerts and loyalty or referral programs.
In this model, charging is no longer a commodity purchase. It becomes an ongoing relationship. Drivers benefit from more confidence, flexibility and price transparency. Charger owners gain a simple way to generate value from assets they already own. Utilities gain more touchpoints to build trust, differentiate their brand and develop new propositions beyond energy supply.
Plug Inn shows what the model can do
Plug Inn proved that a peer-to-peer charging proposition can be built quickly, launched at pace and adopted by the market. Publicis Sapient helped Renault define the vision, business case and MVP for the service in just eight weeks, then brought together strategy, customer experience, engineering and data capabilities to shape the platform. The approach was iterative and data driven, with continuous testing and refinement aimed at reducing risk and improving quality.
Just as importantly, the platform was designed around the elements that make a shared charging model viable: trust, verification, fair pricing, simplicity and reliability. Drivers could locate, reserve and navigate to charging points through a seamless experience. Hosts had a straightforward path to make their chargers available and generate revenue. The result was a community-based service model with measurable traction and broader ecosystem value.
For utilities, the lesson is clear: the future of charging will not be won by infrastructure alone. It will be shaped by the intelligence, usability and interoperability wrapped around that infrastructure.
New business models for a more connected ecosystem
Community charging creates room for utilities to participate in new kinds of value creation. They can bundle charging with home energy offers, managed charging programs or renewable energy propositions. They can partner with OEMs, municipalities and mobility players to simplify the EV journey. They can use charging data to inform new products, better segment customers and deliver more relevant digital services.
They can also help accelerate a broader ecosystem shift. As Publicis Sapient’s work across mobility and energy shows, the greatest value often comes from connecting strategy, product thinking, engineering and data rather than treating charging as a standalone asset play. The organizations that lead will be those that can unify customer experience with operational insight—turning fragmented charging interactions into connected service journeys.
How Publicis Sapient helps utilities lead
Publicis Sapient helps organizations move from concept to launch and ongoing refinement by combining SPEED capabilities: Strategy, Product, Experience, Engineering and Data & AI. In the context of peer-to-peer and community EV charging, that means helping utilities define viable business models, design intuitive customer journeys, build scalable platforms and activate data to improve both user value and operational performance.
That end-to-end approach matters because success in EV charging requires more than an app or a network map. It requires a service model customers trust, a platform that can scale, data that can be turned into action and a strategy that aligns ecosystem partners around shared value.
Plug Inn is one proof point of what that looks like in practice. But the bigger story is what it signals for the market. Utilities have an opportunity to become the hidden growth engine behind peer-to-peer EV charging—expanding access without funding every charger themselves, improving grid outcomes and creating more intelligent, networked services for drivers. Those that seize that opportunity can help shape a more flexible, sustainable and customer-centric future for electrified mobility.
