Starting in 2027, many things will change for households with solar panels or an electric car. The net metering scheme will disappear, and the feed-in tariff will become less favorable. But for smart electric car drivers, there's an opportunity: bidirectional charging . This transforms your EV from a means of transportation into an energy manager. In this article, we explain what bidirectional charging is, what's changing in 2027, and—most importantly—how you can benefit financially from it.
What is bidirectional charging?
With traditional charging, you simply charge your electric car at a charging station. With bidirectional charging, it works both ways: you can not only charge the battery , but also feed power back from the battery to your home or the electricity grid. Your car then becomes a mobile home battery .
Bidirectional charging is possible thanks to technologies such as:
- V2G (Vehicle-to-Grid): you supply energy back to the energy grid
- V2H (Vehicle-to-Home): you power your home
- V2B (Vehicle-to-Building): you support a (company) building
Some models from brands like Hyundai, Kia, Nissan, and MG already support this technology. And the number of compatible vehicles is growing rapidly.
Feed-in tariff in 2027: what will change?
The government is abolishing the current net metering scheme, which until now allowed you to feed in your electricity directly. Instead, you'll receive a lower feed-in tariff from your energy supplier, often just a fraction of the kilowatt-hour price you pay when you consume it.
What does this mean to you?
- Feeding back into the grid yields less
- Storing your own electricity is becoming more interesting
- Smart consumption control (like with your EV) becomes profitable
Bidirectional charging allows you to use your own generated power at times when your energy is most valuable .
This is how smart energy returns via your electric car work
With bidirectional charging, you can charge your car with solar energy during the day and use that power at home in the evening – or feed it back into the grid during peak rates. Combine this with a dynamic energy contract , and you'll earn money from your timing:
- Charge cheaply when the electricity price is low (for example at night or when there is a lot of sun/wind)
- Return when the price is high (for example in the evening when demand is high)
Result: lower costs and potentially higher returns.
Getting maximum benefit: smart charging solutions
To take advantage of bidirectional charging, you need a suitable charging station . Please note:
- The charging station must be able to charge bidirectionally (V2G/V2H support)
- You may need a CCS or CHAdeMO connector depending on your car
- Smart energy management via apps or a load balancing system helps you switch optimally between charging and supplying

Is your car suitable for bidirectional charging?
Not every EV supports this technology. Here are some examples that do:
- Hyundai IONIQ 5/6
- Kia EV6
- Nissan Leaf (with CHAdeMO)
- MG ZS EV (some models)
Many brands are expected to transition to V2G standards in 2025-2027. So check if your next EV supports this.
Not ready yet? Then you can invest in a future-proof charging station so you're ready later.
Future of bidirectional charging
The energy transition requires smart energy storage and usage. Governments and grid operators are investing in pilots for bidirectional charging. This means:
- More support for returns via EVs
- Dynamic rewards based on energy market prices
- New possibilities to make your car part of a local energy grid

Frequently asked questions about bidirectional charging
- What is the difference between V2G and V2H?
- V2G feeds back into the grid; V2H powers your home directly. V2H is ideal for dynamic tariffs or for energy autonomy.
- Does bidirectional charging affect my battery?
- When used correctly, the impact is minimal. Many EVs are specifically designed for this.
- Do I need a special charging station?
- Yes, standard chargers aren't bidirectional. You need a V2G-compatible charging station and a car that supports it.
- Can I also benefit without solar panels?
- Absolutely! Even without generating your own energy, you can charge smartly at low rates and feed it back in at high rates.
