We work with numerous grid operators (see map) to make the smart meter rollout as efficient as possible. If you already have an Ostrom contract and live in the area of one of our partner grids, you can apply for a smart meter in the Ostrom App and switch to our SimplyDynamic tariff.
Is your grid operator not yet a partner of ours? Don't worry, we are already working on further collaborations. As soon as smart meter installation becomes available through another grid operator, we will inform you in our app.

Stiftung Warentest Says...
"Most tariffs are around 21 cents. Ostrom is the cheapest and stands at 19.3 cents." The kilowatt-hour, including VAT and all additional costs, cost only 10.5 cents for our sample household in Berlin with Ostrom. The fixed costs at Ostrom amount to 16.2 cents per kilowatt-hour without VAT. If you subtract the negative electricity price of 7.4 cents from this and factor in VAT again, you arrive at this low price." (translated from German original)

View Testimonials
I have been an Ostrom customer for a while now and am truly impressed by the service. The onboarding process was simple and transparent, and I appreciate the flexibility that Ostrom offers with its digital app. Customer support is responsive, the app is user-friendly, and I always have a clear overview of my electricity consumption and costs. It is refreshing to work with a provider that is both modern and environmentally conscious. Highly recommended!
After several failed attempts to get a smart meter from my grid operator, OSTROM came into the picture. I immediately accepted their unbeatable offer. Since then, heating with electricity and our heat pump has been the only logical choice. Green electricity, sometimes free or even earning us money, with fair, monthly, and transparent billing. Simply the best electricity provider we’ve ever had. What more could you want?
Dank des dynamischen Tarifs und NeoGrid lade ich mein E-Auto genau dann, wenn der Strom günstig und grün ist - und bekomme pro kWh sogar Geld zurück. So wird nachhaltige Mobilität zum No-Brainer.
Klasse ist, dass ich dafür (für die Teilnahme am virtuellen Kraftwerk mit NeoGrid) keine spezielle Hardware brauche, sondern die zeitliche Steuerung der Ladevorgänge über die standardmäßige Cloudverbindung meines Fahrzeugs erfolgt. Einfacher geht es wirklich nicht.
The connection process was fast, and I was quickly offered the "VPP" (Virtual Power Plant) concept as a test user, which won me over immediately.
Ostrom has something for everyone: low energy prices with either a fixed or market rate – combined with fair service, all in one app. For me as a customer, it has really paid off so far!
Durch die Verbindung unserer Wärmepumpe, der PV-Anlage und des E-Autos mit der Ostrom-App profitieren wir optimal vom dynamischen Tarif. So sparen wir automatisch Stromkosten und nutzen die Energie bestmöglich.
Ostrom helps me save money with their dynamic tariff. In combination with my wallbox, I charge my EV at low grid prices. The app is clearly laid out and support responds very quickly!
