Germany has taken a decisive step toward enabling the large-scale adoption of bidirectional charging.
According to a recent report from electrive.net, the German Bundestag has approved a key amendment to national energy legislation, removing the long-criticized double grid fee applied when energy was taken from the grid, stored, and later fed back into it.
This policy shift fundamentally changes the economics of Vehicle-to-Grid (V2G) technology.
With double charging eliminated, V2G is moving from experimental to commercially viable.
This is one of the most significant milestones for Europe’s EV charging and smart energy sectors in recent years.
Why This Policy Matters: The Value of Bidirectional Charging
Bidirectional charging enables electric vehicles to not only receive power from the grid but also supply it back to homes (V2H), buildings (V2B), microgrids, and the public grid (V2G).
This capability plays a strategic role in the future of energy systems:
- Grid stability & peak load management
- EVs as flexible, mobile energy storage
- Higher utilization of renewable power
- New revenue opportunities for operators and EV owners
Until now, regulatory barriers had prevented V2G from achieving meaningful scale.
Germany’s latest decision removes the most significant financial obstacle.
Implications for the European EV & Energy Landscape
The impact will be far-reaching across the mobility and electricity sectors:
1. Growing Demand for V2G-Ready Charging Infrastructure
Operators will increasingly deploy hardware capable of both charging and controlled discharging.
2. Strong Adoption by Fleets and Residential Markets
V2H and V2B will become more practical as EVs integrate into home and building energy systems.
3. EVs Become Active Components of the Smart Grid
Bidirectional charging will influence energy planning, grid flexibility, and market design.
Germany’s decision is widely regarded as the catalyst for Europe’s V2G commercialization cycle.
