Question 1

Can German EV owners earn money with a parked electric car under the new MiSpeL rules?

Accepted Answer

In principle, yes. MiSpeL lets bidirectional charging points be used much like home batteries, buying power at low prices and feeding it back at high prices. Operators have until the end of September 2027 to implement the ruling, and no earnings are guaranteed.

Question 2

What does MiSpeL stand for, and who issued the ruling?

Accepted Answer

MiSpeL stands for Marktintegration von Stromspeichern und Ladepunkten, meaning market integration of electricity storage and charging points. Germany's Federal Network Agency (Bundesnetzagentur) adopted it on 1 October 2026.

Question 3

Why were bidirectional EV charging points excluded from subsidies before MiSpeL?

Accepted Answer

Earlier rules required green and grid electricity to be strictly separated in storage, and only pure green-power storage could receive EEG support. Bidirectional charging points were excluded altogether.

Question 4

How does MiSpeL protect solar subsidies when a battery also charges from the grid?

Accepted Answer

It sets out how to account for the two sources separately. EEG support is retained and is also paid for temporarily stored renewable electricity.

Question 5

Does MiSpeL reduce grid fees and levies for electricity fed back from an EV?

Accepted Answer

Yes. Fed-back quantities are netted, so correspondingly fewer levies and grid fees are due on the original grid purchase. MiSpeL regulates how these quantities are determined.

Question 6

Do I need rooftop solar panels to use MiSpeL with an electric car in Germany?

Accepted Answer

Not necessarily. The rules can be used with subsidised plants, with unsubsidised plants, and even without electricity generation. The simplified flat-rate option is aimed at households with a solar system of up to 30 kWp.

Question 7

How many meters does a household need for each MiSpeL option?

Accepted Answer

The delineation option usually requires two meters, though one is enough in special cases. The flat-rate option generally requires only one.

Question 8

When can German households start using the MiSpeL options for bidirectional charging?

Accepted Answer

Network and metering operators have a transition period until the end of September 2027. During it, the options can be used if both operators agree. The flat-rate option also needs the European Commission's state-aid approval first.
