We love transparent pricing as much as anyone! We offer you our SimplyFair tariff with monthly cancellation, flexible and easy to understand for everyone.
Benefit from electricity at cost price — no hidden fees! All tariffs are risk-free monthly cancellable.
Our energy is always from 100% renewable sources. That's why Ostrom is a certified B Corp™.
Get access to everything stress-free through the Ostrom App. No paper, no fax!
Since we want to help reduce your energy consumption, we detach our profits from it. In contrast to traditional providers, our SimplyFair tariff is based on the current market price, including government taxes and levies.
We only charge a flat 6€ basic fee to cover our costs, that's it!

By observing the market at all times, we’re able to minimize the impact of price fluctuation.
Since we sell our electricity at cost, prices may rise — or fall — according to market prices. In contrast to other providers, we also pass down savings to our customers. In any case, we will inform you at least four weeks in advance.
Cancellation is free at any time. We believe our customers stay with us because they choose to every day, not because of a minimum contract term.
Because let’s be honest: it’s overdue. Simply sign up on our website and manage everything in our app. No need for "email templates" or translation apps!
Access your annual invoices, submit and track your meter readings, and adapt your monthly payments all within the Ostrom app.
With our live customer support chat, get answers to your questions within seconds — not hours or days!
Deutsche Sprache, schwere Sprache. We're a proud German startup, but we also know our language ain’t easy. To maintain full transparency we offer everything — from signup to contract — in English as well.

You can sign up with or without a smart meter, it’s up to you! We offer our SimplyFair tariff for customers with a regular digital meter or our SimplyDynamic with hourly pricing—smart meter required.
Simply sign up for SimplyFair, and if you have a supported smart meter installed, you will be automatically switched to SimplyDynamic. No more worries checking if you have a smart meter or not!
We take pride in providing excellent customer service. But don’t just take our word for it: Hear it from customers who’ve already made the move 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.
Oh yeah, and we have our top-rated app... and our incredible customer support... and our smart integrations... and our certified green energy...
No, there’s no need to wait! Even if your current contract has up to 12 months remaining, you can sign up with Ostrom today. Just sign up now, and we’ll take care of the rest — your contract will seamlessly switch to Ostrom as soon as your existing one ends.
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. Our last price increase was in 2022, and we did 7 price decreases (yes!) since then.
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!
Both have all the great features for all Ostrom customers: risk-free monthly cancellable contract, all the features of the Ostrom App (smart home integrations, referrals, perks, CO2 tracking, Ostrom Store, live customer chat & more!)
While energy prices change often, our SimplyFair tariff removes that complexity for our customers. It's the perfect balance between dynamic prices that change hourly and 24-month contracts that keep you locked in to a high price (think households in 2024 still paying 2022 prices).
Our last price increase was in 2022, and afterwards we did 7 price decreases then. This means our customers quickly received cheaper prices as soon as they came. How awesome is that!
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.
Switch and save in only 5 minutes!
