What Is A Dynamic Tariff?

Our dynamic tariff updates every hour to match the real electricity market price — so you always pay what energy actually costs. When solar and wind production are high, prices drop. In the evenings, when demand increases, they rise. By shifting your consumption to the cheapest hours, you can save up to 35 % — and the Ostrom App makes it easy for you.

Benefits At A Glance:

Electricity At Market Price
We don’t add any profit margin to the electricity you use. You only pay a 6 € monthly service fee — that’s as fair as it gets. Even Stiftung Warentest and Finanztip agree.
Benefit From Affordable Solar And Wind Power
With a dynamic tariff, you benefit whenever renewable energy is abundant. When the sun shines or the wind blows, electricity prices fall — and your savings rise.
Reduce Costs Through Optimization
Optimize your energy use with the Ostrom App by shifting consumption to the cheapest hours. You’ll cut your electricity costs and support a cleaner grid — since the lowest prices usually mean the greenest energy.
Stay Protected From High Prices
With the Ostrom App, you can see tomorrow’s electricity prices and track your past usage — making it easy to avoid price spikes and stay in control of your costs.

View Testimonials
Joachim Vollstedt – SimplyDynamic

Simply the best electricity provider we've ever had.

After several unsuccessful attempts to get a smart meter from the network provider, Ostrom came into play. I immediately accepted the unrivaled affordable offer. Since then, heating with electricity and our heat pump has been absolutely without alternative. Green electricity, sometimes free or even with cash back, fair, monthly, and transparent billing. Simply the best electricity provider we've ever had. What more could you want?

Felix Stausberg – SimplyDynamic

Allows us to automatically save on electricity costs.

By connecting our heat pump, PV system, and electric car with the Ostrom app, we optimally benefit from the dynamic tariff. This allows us to automatically save on electricity costs and use energy in the best possible way.
