The service turns electric cars into distributed energy storage, supporting Germany’s renewable integration and creating new revenue streams for owners. It also showcases a scalable business model that could accelerate V2G adoption across Europe.
Vehicle‑to‑grid technology is emerging as a cornerstone of the energy transition, allowing electric‑vehicle batteries to act as flexible storage assets that balance supply and demand. In markets like Germany, where renewable penetration is high and grid congestion is a growing concern, V2G can provide ancillary services, peak‑shaving, and grid‑stability benefits. By monetising idle battery capacity, V2G also creates a new value proposition for EV owners, turning a traditionally passive asset into an active revenue source.
BMW’s collaboration with Eon leverages both automotive engineering and utility expertise to deliver a turnkey V2G solution. The offering bundles a bidirectional Wallbox Professional, a specialized electricity tariff, and a smart meter, all coordinated through the My BMW app. Financial incentives—up to €720 yearly bonuses and €0.40 per kilowatt‑hour exported—are designed to offset vehicle operating costs and encourage participation. Early adopters receive a €700 wallbox discount, underscoring the partnership’s commitment to rapid market penetration and consumer adoption.
The rollout signals a broader shift toward integrated mobility‑energy ecosystems. As utilities seek distributed resources to defer infrastructure upgrades, and automakers aim to differentiate their EV portfolios, V2G could become a standard feature in future vehicle line‑ups. However, scalability will depend on regulatory clarity, standardized communication protocols, and the economics of battery degradation. If these challenges are addressed, the BMW‑Eon model may serve as a blueprint for other markets, accelerating the convergence of transportation electrification and renewable grid integration.
Munich (Germany) – BMW Group and Eon are launching the first commercial vehicle‑to‑grid (V2G) offering for private customers in Germany.
Effective immediately, the complete product package is available to order, consisting of the bidirectional BMW Wallbox Professional, the Eon Öko‑Strom Home & Drive V2G electricity tariff, including a separate V2G feed‑in contract, and – if not already installed – a smart metering system (smart meter).
The offer is initially aimed at BMW vehicles of the Neue Klasse, starting with the BMW iX3 based on sixth‑generation BMW eDrive technology. These models can not only draw energy from their high‑voltage battery but also feed it back into the power grid. Charging and discharging are automated via an algorithm jointly developed by BMW and Eon.
As part of the contract agreed with Eon, customers receive a time‑based bonus of up to €720 per year, provided the vehicle is connected to the wallbox with the V2G function activated. The bonus is credited regardless of whether actual charging or discharging takes place and is capped at €60 per month. BMW calculates the bonus payment based on a theoretical annual driving distance of up to 14,000 kilometers. In addition, every kilowatt‑hour actually fed into the grid is remunerated at €0.40 per kWh. Control is handled via the My BMW app, where charging targets and bonus balances can also be viewed.
“The first commercial V2G offer in Germany marks a groundbreaking milestone, linking electromobility with the energy transition,” said Filip Thon, CEO of Eon Germany.
Marcus Krieg, Vice President New Business Models at BMW Group, explained: “With the Neue Klasse, BMW vehicles become an active part of the energy ecosystem for the first time. Their technology enables intelligent storage and return of energy to the grid, reducing customer costs while strengthening the use of renewable energy.”
For the first 100 private customers with a BMW iX3 who opt for Eon’s V2G electricity tariff, an additional discount of €700 on the wallbox is available. In parallel, BMW and Eon are offering cost‑optimized charging for all BMW and MINI electric vehicles, where charging processes are automatically shifted to lower‑priced time windows, with additional bonuses possible.
