What Is A Dynamic Tariff?

Our dynamic tariff SimplyDynamic regularly adjusts your energy price based on current electricity prices. 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.

What Our Customers Are Saying

View Testimonials
Joachim Vollstedt – SimplyDynamic

Simply the best electricity provider we've ever had.

Quote icon

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?
