With V2G, cars help you save money

Behind this somewhat childish title lies V2G, a now mature technology that transforms the electric car into a central player in the energy system.
Volkswagen, in partnership with its energy subsidiary Elli, is preparing to launch a complete Vehicle-to-Grid (V2G) offering in Germany starting in the fourth quarter of 2026. The principle: allowing electric vehicles to store electricity and then reinject it into the grid as needed.
The offering is based on an integrated ecosystem that includes a vehicle, application, dynamic electricity tariff, smart meter, and bidirectional charging station. The installation of the meter is already available and constitutes a key step in the rollout.
According to Volkswagen, this approach aims to significantly reduce the total cost of mobility, with potential savings estimated between 700 and 900 euros per year in the most favorable scenarios. Ultimately, charging could become almost cost-neutral for the most flexible customers.
Beyond individual interest, V2G also addresses systemic issues.
By storing surplus renewable energy and reinjecting it during peak demand, vehicles help stabilize the electrical grid and limit energy losses. The group’s modular MEB platform already enables large-scale deployment, with around one million compatible or bidirectionally prepared vehicles in Europe.
With Elli, Volkswagen aims to become a central player in the energy ecosystem by connecting production, storage, and consumption in a single integrated model. The gradual rollout in Europe is expected to follow after Germany, with pre-registrations starting in 2026 and a generalization anticipated for the ID. range models that are already compatible.
