Green Electricity Switch in Germany
Since 6 June 2025, switching electricity providers in Germany takes 24 hours by law (Bundesnetzagentur rule). Compare certified green tariffs in English, pick one, and the new provider handles the rest. Realistic savings sit at 200 to 360 € a year, based on Finanztip’s May 2026 figures.

Key Takeaways
- Technical switch: 24 hours since 6 June 2025 (Bundesnetzagentur).
- Savings from leaving the default tariff (Grundversorgung): 200 to 360 € a year for a 3,000 kWh household (Finanztip, May 2026).
- Three trustworthy green labels: ok-power, Grüner Strom Label, TÜV NORD "Geprüfter Ökostrom". A bare "TÜV-zertifiziert" claim is not enough.
- A 3,500 kWh household avoids about 1.2 tonnes of CO2 a year on a certified green tariff, roughly the footprint of 8,500 km in an average petrol car (Umweltbundesamt 2025).

How the switch actually works
You start the comparison above. Type in your postal code (PLZ), your yearly consumption, and switch the filter to "certified green tariff". If you do not know your kWh number yet, a rough estimate is 1,500 kWh per person in the household per year. The tool returns a sorted list of real providers with their yearly price.
Click the tariff you want and the rest is paperwork the new provider does for you:
- You fill an online form with your address, meter number (Zählernummer), and IBAN.
- The new provider cancels your old contract in your name.
- Once your old cancellation period runs out (Grundversorgung: 14 days; a regular fixed tariff: usually four weeks), the new provider starts delivering.
- On the switch day you read your meter once and send the number to the new provider. Most have an app for it; a photo works.
That is the whole process. You do not have to call your old supplier, write a German letter, or talk to the grid operator.
The 24-hour rule and what changed in June 2025
Before June 2025, the back-office side of a provider switch routinely took three weeks. The EU electricity market directive pushed Germany to fix that. Since 6 June 2025 the Bundesnetzagentur requires every supplier to complete the technical handover inside 24 hours, the moment your old contract ends. The Verbraucherzentrale welcomed the change because the long handover used to discourage people from switching at all.
Two things to keep separate:
- Technical switch (between providers, behind the scenes): 24 hours, fixed by law.
- Your old contract’s notice period: contract-dependent. Grundversorgung is 14 days. A standard fixed tariff is usually four weeks at the end of the contract term.
If you are in a long fixed contract, the switch will not start tomorrow. You can still book the new tariff today; the new provider plans the start date around your old contract end.
What green electricity actually costs in 2026
The household average sat at 37.2 cents per kWh in January 2026, according to the BDEW price monitor. Green tariffs do not have to be more expensive. New-customer green tariffs in 2026 start around 25 cents per kWh, depending on your postal code and consumption level. For a three-person household with 3,000 kWh a year, the numbers look like this:
| Tariff | Price per kWh | Yearly cost |
|---|---|---|
| Grundversorgung (BDEW Ø January 2026) | 37.2 ct | ≈ 1,116 € |
| Finanztip-recommended new-customer tariff (May 2026) | 31.3 ct | ≈ 939 € |
| Cheap certified green tariffs | from 25 ct | from 750 € |
| Possible saving per year | up to 360 € |

One thing to watch when you compare: first-year bonuses (Sofortbonus, Wechselbonus) make the year-one price look smaller than the real long-term cost. The number you want is the "Effektivpreis ab dem zweiten Jahr" (effective price from year two), which most comparison portals show separately.

Which green labels are actually worth something
The word "Ökostrom" is not protected in Germany. Any supplier can put it on a tariff. The signal that matters is the label:
- ok-power-Label (issued by EnergieVision e. V., founded by the Öko-Institut). One of the strictest standards. Requires a share of newly built renewable plants and a fixed investment per kilowatt-hour into more capacity.
- Grüner Strom Label (NABU, BUND, Deutsche Umwelthilfe). Requires the supplier to invest at least 0.5 cents per kWh into new renewable infrastructure. The hardest funding rule on the market.
- TÜV NORD "Geprüfter Ökostrom". Verifies origin and rules out double-counting. The "TÜV NORD" part matters here. A bare "TÜV-zertifiziert" claim has no single fixed standard because several different TÜV bodies use different criteria.
Plain origin certificates (Herkunftsnachweise, HKN) without a label say less than people assume. They can come from old Norwegian hydropower plants without any of your money flowing into the German renewable build-out. The Umweltbundesamt has a clear explainer on this.
One thing to keep in mind for any "100 % CO2-neutral" claim you see in marketing copy: starting 27 September 2026, the EU Empowering Consumers for the Green Transition Directive restricts that kind of blanket claim unless the supplier can document offsets in a specific way. Looking for the three labels above is the safer signal than reading the hero text on a provider’s homepage.
Is the switch worth it for an expat?
Financial side. The average household leaving the default Grundversorgung saves 200 to 360 € a year, according to Finanztip (May 2026). The exact number depends on your consumption and how expensive your current tariff is. If you are still on an old expensive fixed contract, the saving can be higher. Price guarantees of 12 or 24 months are common and they lock in the rate.
Environmental side. On a tariff with the ok-power or Grüner Strom Label, your money funds new renewable capacity. A household with 3,500 kWh of consumption avoids about 1.2 tonnes of CO2 a year, using the German grid emissions factor of 344 g CO2 per kWh ( Umweltbundesamt 2025). For scale: that is roughly the footprint of 8,500 km in an average petrol car ( co2online, 142 g CO2 per km).
One honest caveat: physically, the electricity from your socket is the same mix as your local grid. Your tariff choice acts through where your money goes, not through which electrons reach your flat. That is still the most direct lever a private household has on Germany’s energy transition. If your main motive is price, our cheap green electricity guide takes a price-first angle.

What if you do not speak German?
The comparison tool above runs in English and the contract flow itself does not require fluent German. Two things make life easier for newcomers:
- A small group of providers run their service in English end-to-end. The clearest example is Ostrom (Berlin, 100 % green, app-first, English customer support). Others like Polarstern and Octopus Energy have at least bilingual onboarding.
- For traditional providers (Vattenfall, EnBW, the local Stadtwerke), the contract itself is in German, but the comparison and the cancellation step are automated. You usually do not need to read the small print to switch.
If English-first service is non-negotiable, filter for those providers first, then by price. If you are comfortable with a translator app for the welcome letter, the whole German market opens up and the price floor drops.
On the banking side, most providers accept any German IBAN. Our bank account comparison lists English-friendly options if you do not have a German IBAN yet. If you also need a credit card without a long credit history, free credit cards in Germany covers that.
