Since we want to help reduce your energy consumption, we detach our profits from it. In contrast to traditional providers, our 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 all times.
