The 5 Most Frequently Asked Questions

• #1 Why should I switch to Ostrom?
  Ostrom is the only energy provider that has the same incentives as you - to use less electricity! With our flat 6 € basic fee, we earn the same from a small flat as from a large house. Therefore, unlike every other energy provider, we genuinely want you to use less electricity.

• #2 I still have my contract period with my old provider. Do I have to wait?
  No, there’s no need to wait! Even if your current contract has up to 12 months remaining, you can sign up early with Ostrom today. Just sign up now, and we’ll take care of the rest.

• #3 What is the difference between the SimplyFair and SimplyDynamic tariffs?
  SimplyFair: Our original transparent tariff for all! Easily add meter readings to track your consumption on our app. Energy prices track the market prices on a monthly basis.

SimplyDynamic: Our smart-meter compatible tariff! For those customers who already have a smart meter, automatically see your energy consumption on an hourly basis. This means you can take advantage of low prices when the sun shines or the wind blows!

• #4 I'm worried about price changes. What do they look like at Ostrom?
  While energy prices change often, our SimplyFair tariff removes that complexity for our customers. We truly stick to our electricity-at-fair-prices model. This means that unlike our competitors whose prices mostly only go up, we even pass on decreases as well.

• #5 Does Ostrom offer risk-free, flexible, monthly cancellable contracts?
  Yes! Both our SimplyFair and SimplyDynamic tariffs do not have the typical 12- or 24-month minimum contract periods like every other provider. We want you to stay because you want to, not because you have to.
