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.
