Volkswagen Commercial Vehicles and enercity have launched a pilot project for bidirectional charging. Together, the companies want to show that electric vehicles can be efficiently integrated into the energy market.

The pilot project focuses on the ID. Buzz from Volkswagen and a BiDi-capable charging infrastructure from enercity, which will be used to test the interaction between the vehicle, wallbox, energy management system and virtual power plant. The aim of the project is to demonstrate the technical feasibility, economic potential and social benefits of vehicle-to-grid (V2G) in real-life operation. "The energy transition needs flexibility—and we have long been able to achieve this if we think about mobility and the energy system together," says Aurélie Alemany, CEO of enercity, explaining the importance of the concept. She continues: "With the pilot project, we are making company fleets part of the solution: the e-car batteries provide flexibility exactly when the energy system needs it. This reduces costs for our business customers in the long term—and at the same time supports grid stability and the integration of renewable energies."

Free Driving Possible Under Favorable Conditions

With bidirectional charging of electric vehicles, the electricity not only flows from the grid into the vehicle's battery, but can also be fed back into the grid via the charging station. The flexible use and marketing of this storage capacity can not only reduce energy costs, but also generate additional revenue. Under favorable conditions, the energy company estimates that driving could even be almost free of charge. enercity has already provided the technical proof of concept for bidirectional charging in a laboratory setup. Now it wants to prove the economic viability and scalability of the model.

Easy to Integrate into Everyday Life

In the first step of the pilot, the partners are focusing on the application for commercial customers with plannable downtimes and locations of the company's own fleets—overnight, for example. For this use case, Volkswagen's V2G-capable vehicles will be used to demonstrate that the potential of bidirectional charging can be easily and profitably realized for users in everyday life.

Real-Time Tests This Year

The joint project began in 2025 with preliminary studies and will now be implemented in 2026. It is investigating technical processes, the marketing of flexibility via a virtual power plant and cost reductions in real operation—through real-time tests with real B2B fleets.

With bidirectional charging, enercity has already been able to simulate real market conditions. This combines various sources of revenue such as arbitrage and balancing energy. In addition to the close technical integration of the charging infrastructure into the energy management system, this creates a holistic offering consisting of vehicle, wallbox and energy product.
