We’ve made it our mission to provide green electricity for all. By leveraging tech, we keep things lean and simple, allowing us to focus on our customer’s needs and stay 100% green — without needing to markup our tariffs like other providers.
We sell our energy at cost because we'd rather our customers consume less, instead of more.
We sign with 100% renewable energy sources, meaning your power comes from the best places.
Read your meter, manage your payments, or chat with us live—all in one app. No letters, no fax!
Moving apartments? Leaving the country? We support you all the way. With our flexible tariff, you won’t be locked into contracts or sent bills for the electricity you didn't use. Sign up with us now within minutes — and cancel even faster.Our Tariff
