Germany’s Federal Network Agency (Bundesnetzagentur) adopted its determination on the market integration of storage and charge points, known as MiSpeL, on 1 October 2026. The rules treat bidirectional charge points as far as possible like stationary batteries. Households and businesses can now store both grid power and their own solar power and feed it back, without losing support under Germany’s Renewable Energy Sources Act (EEG). Grid operators and metering operators have until the end of September 2027 to implement the rules.
Key Takeaways
- Germany’s MiSpeL rules, adopted 1 October 2026, put bidirectional charge points on a similar footing to batteries.
- EEG support is kept for stored renewable power, and re-fed grid power is netted for levies and grid fees.
- A simple one-meter option targets homes with solar up to 30 kWp, pending EU state-aid approval.
- Network and metering operators have until end of September 2027 to implement.
What Changes
- Before: green power and grid power in storage had to be kept strictly separate. Only pure green-power storage qualified for EEG support, and bidirectional charge points were excluded.
- Now: EEG support is kept and also paid for renewable power that was stored temporarily, including in an EV battery.
- Grid power that is taken from the grid and later fed back is netted, so less levies and grid fees are paid on it.
- The rules work with subsidised and unsubsidised renewable plants, and even at sites with no generation at all.
Two Options for Measuring
| Option | Who it suits | Metering |
|---|---|---|
| Separation option (Abgrenzungsoption) | All users; exact calculation of eligible and netted volumes | Usually two meters; one in special cases |
| Flat-rate option (Pauschaloption) | Households with a solar system up to 30 kWp | Generally one meter |
The flat-rate option cannot be used until the European Commission approves the underlying law under state-aid rules. During the transition period, the rules can be applied early if the grid operator and metering operator agree.
Bundesnetzagentur President Klaus Müller said bidirectional use of charge points helps both e-mobility and the power system, and that Germany can become a frontrunner in bidirectional charging.
What It Means
For home energy installers, MiSpeL removes a key regulatory barrier to vehicle-to-home and vehicle-to-grid set-ups in Germany. Combined with dynamic electricity tariffs, an EV can charge when prices are low and supply power back when prices are high. Real-world use still depends on vehicles and chargers that support bidirectional power flow, plus the right metering.
For most households today, the practical step is smart, tariff-aware AC charging, which already captures much of the price benefit. A connected Type 2 wallbox with app scheduling, such as the EV-ACT3204E, fits that role. Distributors planning bidirectional ranges can discuss requirements through our OEM and private-label programme.
