Changing your provider is quite simple – after you have completed the signup, we will contact your current electricity supplier and your network operator. You don’t have to take care of anything else!

No need – we take care of everything for you. Although, if during the signup process, you do not choose to give us the right to do so (Sonderkündigungsrecht), you will have to handle the cancellation of your previous provider.

If you experience either an electricity price increase or a pending change of address, you may have this special cancellation right.

In this case, we are not able to terminate the contract for you for legal reasons. You will have to cancel the contract in writing to your previous provider.

You can use our draft.

No – your previous electricity provider will communicate with us the exact date of change. In addition, the basic utility (Grundversorgung) will always act as a fallback in any eventuality.

Ostrom immediately takes of the switchover process. The handover may be required to wait based on your previous provider.

Your signup can still be completed today, and you only Start with Ostrom after a successful change of contract.

Your meter number can be easily found from your electricity bill. It will be usually listed on the top.

Alternatively, this is also available on your electricity meter. The meter is usually at homes by the front door, in the hallway or at the basement. For apartments, best to ask your landlord or your building manager (Hausverwaltung) for details.

The Marktlokations-ID represents your locatin within the grid system. Your Marktlokations-ID can easily be found on your last electric bill.

We are happy to continue serving you at your new address as Ostrom is available throughout Germany. Do note, however, that the local network charges may vary. Write us an e-mail to hallo@ostrom.de for more details.

Contract & Invoice

Our tariff consists of a fair monthly fee. Unlike other electricity providers, we explicitly do not add overheads to your consumption. The greenest energy is the one you wind up never needing. We want to align our incentives with you, less power is the best power.

Electricity contracts all function with the same calculation – a basic fee from consumption together with taxes and environmental levies. Based on the answers you provided during your signup such as your address and your household size, we estimate your forecasted consumption. This will be the amount you will be charged monthly. From the app you can easily toggle the amount monthly based on your usage. Any deviations are balanced out at the end of the year (Nachzahlung).

You have two main payment options: either you give us a SEPA direct debit mandate, which will automatically deduct your payment from your account each month, during the signup process or you can do a manual bank transfer each month.

The due date is always at the beginning of the month, due to our flexible monthly contract. For example, the charge for the month of May will be during the 1st of May.

Your first bill will be sent after one year with Ostrom. This will show your total billing over the month. If you want to get a more accurate reading, you can use our app to submit your meter reading.

An Abschlag is the monthly payment deduction based on your forecasted electricity consumption. If you use less power you get money back at the end of the year and vice versa. So if you were billed EUR 500 and you wind up using only EUR 400 of electricity at the end of the year, you’ll be debited back EUR 100.

You can easily change your monthly fee on the app with just a few taps.

There is no minimum contract period (Mindestlaufzeit) and you can cancel anytime within the month with a 4 weeks notice period (Kündigungfrist). Unlike other providers we only offer flexible monthly contracts and will never charge you early exit fees.

While that’s unfortunate, we understand and we aim to make even this process as easy as possible. We are legally required to receive this notice in writing – simply email us at hallo@ostrom.de your desire to cancel ideally from the same email you used to sign up with us and your details such as your meter number, your Marktlokation-ID and your full name.

Everything is set from your side! From here, we will contact your old electricity provider and cancel your contract with them. Once we’ve sorted out your earliest possible termination date, we begin the switching process.

Note that this process may take about 2 weeks. Nothing to worry about, once there is news, you will get an email from us about the change.
